Rakesh SharmaBorn: January 13, 1949 (age 63), PatialaWing Commander Rakesh Sharma, AC (Ashok Chakra Award), Hero of the SovietUnion, is a former Indian Air Force test pilot who flew aboard Soyuz T-11 as partof the Intercosmos program.Sharma was the first Indian to travel in space.The Intercosmos Research Team was a program that was conducted by theSoviet Union and included active participation from allied countries such asIndia, Syria and France. Rakesh Sharma was chosen for this assignment andever since, he has been an inspiration to upcoming cosmonauts.Early Life:On January 13th 1949, Rakesh Sharma was born in the well-known district of Patiala located in the stateof Punjab. As a young boy, he enrolled at St. Georges Grammar School in Hyderabad and received hisearly education from there.Sharma joined the Indian Air Force in 1970 as a pilot officer after joining the NDA as an IAF cadet in1966.Career:In 1970, after joining the Indian Air Force as a test pilot, his passion for flying opened up severalopportunities such as being a part of war operations against Pakistan.He flew various Mikoyan-Gurevich (MiG) aircrafts starting from 1971. Rakesh swiftly progressedthrough many levels and in 1984 he was appointed as the Squadron Leader and pilot of the Indian AirForce.He was a squadron leader with the Indian Air Force, when he flew into space in 1984 as part of a jointprogramme between the Indian Space Research Organisation (ISRO) and the Soviet Intercosmos spaceprogram.He spent eight days journeying around the Earths orbit in a space station called Salyut 7. He joined twoother Soviet cosmonauts aboard the Soyuz T-11 spacecraft which blasted off on April 2, 1984.Spaceflight:Sharma joined the Indian Air Force and progressed rapidly through the ranks.Sharma, then a Squadron Leader and pilot with the Indian Air Force embarked on a historic mission in1984 as part of a joint space program between the Indian Space Research Organisation andFirst Indian totravel into Space

Eight days) in space and board the Salyut 7 space station, a low earth orbit space station,conducting an earth observation programme concentrating on India. He also did life sciences andmaterials processing experiments, including silicium fusing tests. He is also reported to haveexperimented with practicing Yoga to deal with the effects of prolonged orbital spaceflight.While Rakesh was in space, he was asked by the then Prime Minister Indira Gandhi on a famousconversation, who asked him how does India looks from space, Rakesh replied"Saare Jahan se Achcha Hindustan Hamara"Meaning Our land of Hindustan, is the Best in the world.A few years later he retired from the Indian Army as a Wing Commander.He joined the Hindustan Aeronautics Limited in 1987 and served as Chief Test Pilot in the HAL NashikDivision until 1992.He then shifted to National Flight Test Center (NFTC) in Bangalore and began to work on Light CombatAircraft program, along with a few others.He retired from test flying in 2001.In 2006, Sharma took part in a conference involving a gathering of the best scientists of ISRO, who wereresponsible for one of Indias space missions. Currently, he has retired from his services and is now thechairperson for the Automated Workflow.Honors:He was conferred with the honor of Hero of Soviet Union upon his return from space.The Government of India conferred its highest gallantry award (during peace time), the AshokaChakra on him and the other two Soviet members of his mission.Timeline:1949: Rakesh Sharma was born in Patalia into a Punjabi family.1966: He joined the National Defense Academy as an Air Force trainee.1970: Appointed as a test pilot by Indian Air Force.1971: Rakesh Sharma flew the Mikoyan-Gurevich, a Russian jet.1984: He was a part of a space mission owing to which he became the first man to travel to space.2006: He took part in a space conference held by ISRO.
  3. 3. Kalpana ChawlaBorn: July 1, 1961, KarnalDied: February 1, 2003, TexasKalpana Chawla was an Indian-American astronaut who, was a missionspecialist on the space shuttle Columbia.She first flew on the space shuttle Columbia in 1997 as a mission specialistand primary robotic arm operator. Chawla was one of seven crew memberskilled in the Space Shuttle Columbia disaster.Kalpana Chawla was Indias first women aeronautical engineer to travel intospace. She has been a role model to several women in terms of achievementand contributions to the field of aeronautics.Early Life:Kalpana Chawla was born on the 1st of July, 1961 in a small town in Karnal located in the state ofHaryana. Her parents, Banarasi Lal Chawla and Sanjyothi had two other daughters named Sunita andDeepa and a son named Sanjay.Kalpana was the youngest in her family and hence, she was the most pampered too.She got educated at the Tagore Public School and later enrolled into Punjab Engineering College tocomplete her Aeronautical Engineering Degree in 1982. In the same year, she moved to the US. She gotmarried to Jean-Pierre Harrison in 1983. He was her flying instructor and an aviation author.In 1984, she completed her M.S. in Aerospace Engineering from the University of Texas in Arlington. In1988, she obtained a Ph.D. in the same subject from the University of Colorado at Boulder.Career:Kalpana Chawla was a certified flight instructor who rated aircrafts and gilders. She also held acommercial pilot license for single and multi-engine airplanes, hydroplanes and gliders. Kalpana was alicensed Technician Class Amateur Radio person certified by the Federal Communication commission.Owing to her multiple degrees in Aerospace, she got a job in NASA as the Vice President of the OversetMethods, Inc. in 1993. She was extensively involved in computational fluid dynamics research onVertical/Short Takeoff and LandingChawla joined the NASA Astronaut Corps in March 1995 and was selected for her first flight in 1996.She spoke the following words while traveling in the weightlessness of space, "You are just yourintelligence". She had traveled 10.4 million km, as many as 252 times around the Earth.First Indian Womanto Travel intoSpace
  4. 4. First Space Mission:Her first space mission began on November 19, 1997 as part of the six-astronaut crew that flewthe Space Shuttle Columbia flight STS-87.Chawla was the first Indian-born woman and the second Indian person to fly in space, followingcosmonaut Rakesh Sharma who flew in 1984 in a spacecraft.On her first mission Chawla traveled over 10.4 million miles in 252 orbits of the earth, logging more than372 hours in space. During STS-87, she was responsible for deploying the Spartan Satellite whichmalfunctioned, necessitating a spacewalk by Winston Scott and Takao Doi to capture the satellite.A five-month NASA investigation fully exonerated Chawla by identifying errors in software interfacesand the defined procedures of flight crew and ground control.After the completion of STS-87 post-flight activities, Chawla was assigned to technical positions in theastronaut office to work on the space station, her performance in which was recognized with a specialaward from her peers.Next Space Mission:In 2000, she was again assigned on her second flight mission as a part of Flight STS-107. Kalpanasresponsibility included microgravity experiments. Along with her team members, she undertook adetailed research on advanced technology development, astronaut health & safety, the study of Earthand space science. During the course of this mission, there were several mishaps and cracks weredetected in the shuttle engine flow liners.On January 16, 2003, Chawla finally returned to space aboard Columbia on the ill-fated STS-107mission.Death:It was on February 1st 2003 that the space shuttle, STS-107, collapsed over the Texas region when it re-entered the Earths atmosphere. This unfortunate event ended the lives of seven crew membersincluding Kalpana.Awards:She was the first Indian woman to travel in a space shuttle for 372 hours and complete 252 rotationsaround the Earths atmosphere. Her achievements have been an inspiration to many others in India andabroad. There are many science institutions named after her.Posthumously awarded:Congressional Space Medal of HonorNASA Space Flight MedalNASA Distinguished Service Medal

  6. 6. Vikram SarabhaiBorn: August 12, 1919, AhmedabadDied: December 31, 1971, KovalamVikram Ambalal Sarabhai was an Indian physicist.He is considered to be the “father of the Indian space program”Early Years & Education:Vikram Ambalal Sarabhai was born on August 12, 1919 at Ahmedabad in anaffluent family of progressive industrialists. He was one of eight children ofAmbalal and Sarla Devi. He had his early education in a private school,“Retreat” run by his parents on Montessori lines.Marriage and children:In September, 1942, Vikram Sarabhai married Mrinalini Sarabhai, a celebrated classical dancer. Thewedding was held in Chennai without anyone from Vikrams side of the family attending the weddingceremony because of the ongoing Quit India movement led by Mahatma Gandhi.Vikram and Mrinalini had two children - Kartikeya and Mallika. Vikram Sarabhai had a troubledmarriage and was in a long term relationship with Dr.Kamala Choudhary.His daughter Mallika Sarabhai was awarded the Padma Bhushan, Indias third highest civilian honor forthe year 2010 and his son Kartikeya Sarabhai was awarded the Padma Shri in 2012.After his matriculation, Vikram Sarabhai proceeded to Cambridge for his college education and took thetripods degree from St. Johns college in 1940. When World War II began, he returned home and joinedas a research scholar under Sir C. V. Raman at the Indian Institute of Science, Bangalore His interest insolar physics and cosmic ray led him to set up many observation stations around the country. He builtthe necessary equipment with which he took measurements at Bangalore, Poona and the Himalayas. Hereturned to Cambridge in 1945 and completed his Ph.D in 1947.Physical Research Laboratory:Vikram Sarabhai was instrumental in establishing the Physical Research Laboratory (PRL) in Ahmedabadin November 1947. The laboratory was established in a few rooms in M.G. Science Institute of theAhmedabad Education Society, which was founded by his parents. Subsequently, it got support from theCouncil of Scientific and Industrial Research (CSIR) and the Department of Atomic Energy.At the young age of 28, he was asked to organise and create the ATIRA, the Ahmedabad TextileIndustry’s Research Association and was its Honorary Director during 1949-56. He also helped build anddirect the Indian Institute of Management, Ahmedabad from 1962-1965.Father of the IndianSpace Program
  7. 7. Indian Space Programme:Dr. Homi Jehangir Bhabha, widely regarded as the father of Indias nuclear science program, supportedDr. Sarabhai in setting up the first rocket launching station in India (TERLS)at Thumba near Thiruvananthapuram on the coast of the Arabian Sea, primarily because of its proximityto the equator. After a remarkable effort in setting up the infrastructure, personnel, communicationlinks, and launch pads, the inaugural flight was launched on November 21, 1963 with a sodium vapourpayload.As a result of Dr. Sarabhais dialogue with NASA in 1966, the Satellite Instructional TelevisionExperiment (SITE) was launched during July 1975 – July 1976 (when Dr.Sarabhai was no more).Dr. Sarabhai started a project for the fabrication and launch of an Indian satellite. As a result, the firstIndian satellite, Aryabhata, was put in orbit in 1975 from a Russian Cosmodrome.Dr. Sarabhai was very interested in science education and founded a Community Science Centre atAhmedabad in 1966. Today, the centre is called the Vikram A Sarabhai Community Science Centre.After the sudden death of Homi Bhabha in an air crash, Vikram Sarabhai was appointed Chairman,Atomic Energy Commission in May 1966. He wanted the practical application of science to reach thecommon man. He decided to acquire competence in advance technology for the solution of country’sproblems based on technical and economic evaluation of its real resources. He initiated India’s spaceprogramme, which today is renowned all over the world.Death:Sarabhai died on 30 December 1971 at Halcyon Castle, Thiruvananthapuram, Kerala. He was visitingThiruvananthapuram to attend the foundation stone laying ceremony of the Thumba railway stationbeing built to service the newly created Thumba Equatorial Rocket Launching Station.Awards:Shanti Swarup Bhatnagar Award (1962)Padma Bhushan (1966)Padma Vibhushan, posthumous (after-death) (1972)Distinguished Positions:President of the Physics section, Indian Science Congress (1962),He was the Chairman of the Atomic Energy Commission in 1966,President of the General Conference of the I.A.E.A., Verína (1970),Vice-President, Fourth U.N. Conference on Peaceful uses of Atomic Energy (1971)
  8. 8. Honours:The Vikram Sarabhai Space Centre, (VSSC), which is the Indian Space Research Organizations leadfacility for launch vehicle development located in Thiruvananthapuram (Trivandrum), capital of Keralastate, is named in his memory.Along with other Ahmedabad-based industrialists, he played a major role in setting up of the IndianInstitute of Management, Ahmedabad.In 1974, the International Astronomical Union at Sydney decided that a Moon Crater BESSEL in the Seaof Serenity will be known as the Dr. Sarabhai Crater.
  9. 9. C V RamanBorn: November 7, 1888, TiruchirapalliDied: November 21, 1970, BangaloreSir Chandrasekhara Venkata Rāman, FRS, was an Indian physicist whosework was influential in the growth of science in India.He was the recipient of the Nobel Prize for Physics in 1930 for thediscovery that when light traverses a transparent material, some of thelight that is deflected changes in wavelength. This phenomenon is nowcalled Raman scattering and is the result of the Raman Effect.Early Life:Chandrashekhara Venkata Raman was born on November 7, 1888 inTiruchinapalli, Tamil Nadu. He was the second child of Chandrasekhar Iyer and Parvathi Amma. Hisfather was a lecturer in mathematics and physics, so he had an academic atmosphere at home. Heentered Presidency College, Madras, in 1902, and in 1904 passed his B.A. examination, winning the firstplace and the gold medal in physics. In 1907, C.V. Raman passed his M.A. obtaining the highestdistinctions.Career:During those times there were not many opportunities for scientists in India.Therefore, Raman joined the Indian Finance Department in 1907. After his office hours, he carried outhis experimental research in the laboratory of the Indian Association for the Cultivation of Science atCalcutta. He carried out research in acoustics and opticsIn 1917, Raman resigned from his government service and took up the newly created Palit Professorshipin Physics at the University of Calcutta. At the same time, he continued doing research at the IndianAssociation for the Cultivation of Science, Calcutta, where he became the Honorary Secretary.He was elected to the Royal Society of London in 1924 and the British made him a knight of the BritishEmpire in 1929.On February 28, 1928, Raman led experiments at the Indian Association for Cultivation of Science withcollaborators, including K. S. Krishan, on the scattering of light, when he discovered the Raman effectthat tells when light traverses a transparent material, some of the light that is deflected changes inwavelength.Raman spectroscopy came to be based on this phenomenon, and Ernest Rutherford referred to it in hispresidential address to the Royal Society in 1929.Raman was president of the 16th session of the Indian Science Congress in 1929. He was conferreda knighthood, and medals and honorary doctorates by various universities.Second Indian & FirstIndian Scientist to Receivethe Nobel Prize
  10. 10. Raman was confident of winning the Nobel Prize in Physics as well, and was disappointed when theNobel Prize went to Richardson in 1928 and to de Broglie in 1929.He was so confident of winning the prize in 1930 that he booked tickets in July, even though the awardswere to be announced in November, and would scan each days newspaper for announcement of theprize, tossing it away if it did not carry the news. He did eventually win the 1930 Nobel Prize inPhysics "for his work on the scattering of light and for the discovery of the effect named after him".He was the first Asian and first non-White to receive any Nobel Prize in the sciences.Before him Rabindranath Tagore (also Indian) had received the Nobel Prize for Literature in 1913.During his tenure at IISc, he recruited the then talented electrical engineering student, G. N.Ramachandran, who later was a distinguished X-ray crystallographer himself.Raman also worked on the acoustics of musical instruments. He worked out the theoryof transverse vibration of bowed strings, on the basis of superposition velocities.He was also the first to investigate the harmonic nature of the sound of the Indian drums such asthe tabla and the mridangam.Raman and his student, Nagendra Nath, of Mim high school, provided the correct theoreticalexplanation for the acousto-optic effect (light scattering by sound waves), in a series of articles resultingin the celebrated Raman-Nath theory.In 1934, Raman became the assistant director of the Indian Institute of Science in Bangalore, wheretwo years later he continued as a professor of physicsHe also started a company called cv Chemical and Manufacturing Co. Ltd. in 1943 along with Dr.Krishnamurthy. The Company during its sixty year history established four factories in Southern India.In 1947, he was appointed as the first National Professor by the new government of IndependentIndia.He retired from the Indian Institute in 1948 and a year later he established the Raman Research Institutein Bangalore, where he worked till his death.Sir C.V. Raman died on November 21, 1970.Personal life:He was married on 6 May 1907 to Lokasundari Ammal (1892–1980) with whom he had two sons,Chandrasekhar and Radhakrishnan.On his religious views, he was said to be an agnostic.C.V. Raman was the paternal uncle of Subrahmanyan Chandrasekhar, who later won the Nobel Prize inPhysics (1983) for his discovery of the Chandrasekhar limit in 1931 and for his subsequent work on thenuclear reactions necessary for stellar evolution.
  11. 11. Honours and Awards:Raman was honored with a large number of honorary doctorates and memberships of scientificsocieties.• He was elected a Fellow of the Royal Society early in his career (1924)• The British made him a knight of the British Empire in 1929.• In 1930 he won the Nobel Prize in Physics.• In 1941 he was awarded the Franklin Medal.• In 1954 he was awarded the Bharat Ratna.• He was awarded the Lenin Peace Prize in 1957.• In 1998, the American Chemical Society and Indian Association for the Cultivation ofScience recognized Ramans discovery as an International Historic Chemical Landmark.National Science Day:India celebrates National Science Day on 28 February of every year to commemorate the discovery ofthe Raman Effect in 1928.

This limit is now known as the Chandrasekhar limit.He obtained his doctorate in 1933. Soon after receiving his doctorate, Chandrasekhar was awarded thePrize Fellowship at Trinity College, Cambridge. In 1937, he accepted the position of Research Associateat the University of Chicago. Chandrasekhar stayed at University of Chicago throughout his career,becoming the Morton D. Hall Distinguished ServiceProfessor in Astronomy and Astrophysics in 1952. In1952 he established the Astrophysical Journal and was its editor for 19 years, transforming it from alocalpublication of the University of Chicago into the national journal of the American Astronomical Society.He became a US citizen in 1958.Career:Subrahmanyan Chandrasekhar is best known for his discovery of Chandrasekhar Limit. He showed thatthere is a maximum mass which can be supported against gravity by pressure made up of electrons andatomic nuclei.The value of this limit is about 1.44 times a solar mass. The Chandrasekhar Limit plays a crucial role inunderstanding the stellar evolution. If the mass of a star exceeded this limit, the star would not becomea white dwarf. It would continue to collapse under the extreme pressure of gravitational forces. Theformulation of the Chandrasekhar Limit led to the discovery of neutron stars and black holes. Dependingon the mass there are three possible final stages of a star - white dwarf, neutron star and black hole.Apart from discovery of Chandrasekhar Limit, major work done by Subrahmanyan Chandrasekharincludes:• Theory of Brownian motion (1938-1943)• Theory of the illumination and the polarization of the sunlit sky (1943-1950)• Theory of the illumination and the polarization of the sunlit sky (1943-1950)• The equilibrium and the stability of ellipsoidal figures of equilibrium, partly in collaboration withNorman R. Lebovitz (1961-1968)• The general theory of relativity and relativistic astrophysics (1962-1971) and• The mathematical theory of black holes (1974- 1983).Nobel Prize:Subrahmanyan Chandrasekhar was awarded (jointly with the nuclear astrophysicist W.A. Fowler) theNobel Prize in Physics in 1983. He died on August 21, 1995.Legacy:• In 1999, NASA named the third of its four "Great Observatories" after Chandrasekhar. Thisfollowed a naming contest which attracted 6,000 entries from fifty states and sixty-one

  15. 15. Homi J BhabhaBorn: October 30, 1909, MumbaiDied: January 24, 1966, Mont BlancHomi Bhabha, whose full name was Homi Jehnagir Bhabha, was a famousIndian atomic scientist.In Independent India, Homi Jehnagir Bhabha, with the support of JawaharlalNehru, laid the foundation of a scientific establishment and was responsiblefor the creation of two premier institutions, Tata Institute of FundamentalResearch and Bhabha Atomic Research Centre(former name is the TrombayAtomic Energy Establishment).Homi Bhabha was the first chairman of Indias Atomic Energy Commission.Colloquially known as “father of Indian nuclear programme”Early life:Homi Jehangir Bhabha was born on October 30, 1909, in Bombay in a rich Parsi family. He received hisearly education at Bombays Cathedral Grammar School and entered Elphinstone College at age 15 afterpassing his Senior Cambridge Examination with Honors.His name, Jahangir (Jehangir), is from Persian meaning “conqueror of the world.”He then attended the Royal Institute of Science until 1927 before joining Caius College of CambridgeUniversity. This was due to the insistence of his father and his uncle Dorab Tata, who planned forBhabha to obtain a degree in Mechanical engineering from Cambridge and then return to India, wherehe would join the Tata Steel Mills in Jamshedpur as a metallurgist.Research in Nuclear physics:In January 1933, Bhabha received his doctorate in nuclear physics after publishing his first scientificpaper, "The Absorption of Cosmic radiation".In the publication, Bhabha offered an explanation of the absorption features and electron showerproduction in cosmic rays. The paper helped him win the Isaac Newton Studentship in 1934, which heheld for the next three years. The following year, he completed his doctoral studies in theoreticalphysics under Ralph H. Fowler.During his studentship, he split his time working at Cambridge and with Niels Bohr in Copenhagen. In1935, Bhabha published a paper in the Proceedings of the Royal Society, Series A, in which performedthe first calculation to determine the cross section of electron-positron scattering. Electron-positronscattering was later named Bhabha scattering, in honor of his contributions in the field.First chairman ofIndias Atomic EnergyCommission
  16. 16. Return to India:Due to outbreak of Second World War, Homi Jehangir Bhabha, returned to India in 1939.He set up the Cosmic Ray Research Unit at the Indian Institute of Science, Bangalore under C. V. Ramanin 1939.With the help of J.R.D. Tata, he established the Tata Institute of Fundamental Research at Mumbai.In 1945, he became director of the Tata Institute of Fundamental Research.Apart from being a great scientist, Homi Bhabha, was also a skilled administrator. After independence hereceived the blessings of Jawaharlal Nehru for peaceful development of atomic energy.He established the Atomic Energy Commission of India in 1948 and was its chairman.Under his guidance Indian scientists worked on the development of atomic energy, and the first atomicreactor in Asia went into operation at Trombay, near Bombay, in 1956.Under his guidance, nuclear reactors like the Apsara, Cirus and Zerlina were built.Homi Bhabha was chairman of the first United Nations Conference on the Peaceful Uses of AtomicEnergy, held in Geneva in 1955.He advocated international control of nuclear energy and the outlawing of atomic bombs by allcountries. He wanted nuclear energy to be used for alleviating poverty and misery of people.He was the President of the International Union of Pure and Applied Physics from 1960 to 1963.Death:Homi Bhabha died in an aeroplane crash in Switzerland on January 24, 1966.Legacy:After his death, the Atomic Energy Establishment at Trombay was renamed as the Bhabha AtomicResearch Centre in his honour.In addition to being an able scientist and administrator, Bhabha was also a painter and a classical musicand opera enthusiast, besides being an amateur botanistThe Homi Bhabha Fellowship Council has been giving the Homi Bhabha Fellowships since 1967 Othernoted institutions in his name are the Homi Bhabha National Institute, an Indian deemed university andthe Homi Bhabha Centre for Science Education, Mumbai, India.He is the recipient of the Adam’s Award, Padma Bhushan, an Honorary Fellow of the American Academyof Arts and Sciences and Foreign Associate of the National Academy of Sciences in the United States.
  17. 17. Jagadish Chandra BoseBorn: November 30, 1858, BikrampurDied: November 23, 1937, GiridihAcharya Sir Jagadish Chandra Bose, CSI, CIE, FRS was an Indian Bengalipolymath: a physicist, biologist, botanist, archaeologist, as well as an earlywriter of science fiction.He pioneered the investigation of radio and microwave optics, made verysignificant contributions to plant science, and laid the foundationsof experimental science in the Indian subcontinent.He was the first to prove that plants too have feelings. He inventedwireless telegraphy a year before Marconi patented his invention.IEEE (Institute of Electrical and Electronics Engineers) named him one ofthe fathers of radio science.He is also considered the father of Bengali science fiction.He was the first person from the Indian subcontinent to receive a US patent, in 1904.He also invented the crescograph (A crescograph is a device for measuring growth in plants. It wasinvented in the early 20th century by Sir Jagadish Chandra Bose, an Indian scientist)Early Life:Sir Jagadish Chandra Bose was born in Bikrampur, Bengal, (now Munshiganj District of Bangladesh) on30 November 1858.His father Bhagabanchandra Bose was a Deputy Magistrate. Jagadish Chandra Bose had his earlyeducation in village school in Bengal medium. In 1869, Jagadish Chandra Bose was sent to Calcutta tolearn English and was educated at St.Xaviers School and College. He was a brilliant student. He passedthe B.A. in physical sciences in 1879.In 1880, Jagdishchandra Bose went to England. He studied medicine at London University, England, for ayear but gave it up because of his own ill health. Within a year he moved to Cambridge to take up ascholarship to study Natural Science at Christs College Cambridge. In 1885, he returned from abroadwith a B.Sc. degree and Natural Science Tripos (a special course of study at Cambridge).Joining Presidency CollegeBose returned to India in 1885, carrying a letter from Fawcett, the economist to Lord Ripon, Viceroy ofIndia.Father of the BengaliScience Fiction &Inventor of Cresco graph
  18. 18. On Lord Ripon’s request Sir Alfred Croft, the Director of Public Instruction, appointed Bose officiatingprofessor of physics in Presidency College. The principal, C. H. Tawney, protested against theappointment but had to accept it.Bose was not provided with facilities for research. On the contrary, he was a ‘victim of racialism’ withregard to his salary.In those days, an Indian professor was paid Rs. 200 per month, while his European counterpart receivedRs. 300 per month. Since Bose was officiating, he was offered a salary of only Rs. 100 per month. Withremarkable sense of self respect and national pride he decided on a new form of protest.Bose refused to accept the salary cheque. In fact, he continued his teaching assignment for three yearswithout accepting any salary.Finally both the Director of Public Instruction and the Principal of the Presidency College fully realizedthe value of Bose’s skill in teaching and also his lofty character. As a result his appointment was madepermanent with retrospective effect. He was given the full salary for the previous three years in a lumpsum.As a teacher Jagdish Chandra Bose was very popular and engaged the interest of his students by makingextensive use of scientific demonstrations. Many of his students at the Presidency College were destinedto become famous in their own right. These included Satyendra Nath Bose and Meghnad Saha.Radio Research:In 1894, Jagadish Chandra Bose decided to devote himself to pure research. He converted a smallenclosure adjoining a bathroom in the Presidency College into a laboratory. He carried out experimentsinvolving refraction, diffraction and polarization. It would not be wrong to call him as the inventor ofwireless telegraphy.In 1895, a year before Guglielmo Marconi patented this invention, he had demonstrated its functioningin public.Bose wrote in a Bengali essay, Adrisya Alok (Invisible Light), “The invisible light can easily pass throughbrick walls, buildings etc. Therefore, messages can be transmitted by means of it without the mediationof wires.”Jagdish Chandra Bose later switched from physics to the study of metals and then plants. He fabricated ahighly sensitive "coherer", the device that detects radio waves. He found that the sensitivity of thecoherer decreased when it was used continuously for a long period and it regained its sensitivity whenhe gave the device some rest. He thus concluded that metals have feelings and memory.In May 1897, two years after Boses public demonstration in Kolkata, Guglielmo Marconi conducted hiswireless signaling experiment on Salisbury Plain.In 1899, Bose announced the development of a "iron-mercury-iron coherer with telephone detector" ina paper presented at the Royal Society, London.Sir Nevill Mott, Nobel Laureate in 1977 for his own contributions to solid-state electronics, remarkedthat:
  19. 19. "J.C. Bose was at least 60 years ahead of his time" and "In fact, he had anticipated theexistence of P-type and N-type semiconductors."Plants research:Jagdish Chandra Bose showed experimentally plants too have life. He invented an instrument to recordthe pulse of plants and connected it to a plant. The plant, with its roots, was carefully picked up anddipped up to its stem in a vessel containing bromide, a poison. The plants pulse beat, which theinstrument recorded as a steady to-and-fro movement like the pendulum of a clock, began to growunsteady. Soon, the spot vibrated violently and then came to a sudden stop. The plant had died becauseof poison.He founded the Bose Institute at Calcutta, devoted mainly to the study of plants. Today, the Institutecarries research on other fields too.Science Fiction:In 1896, Bose wrote Niruddesher Kahini, the first major work in Bengali science fiction. Later, he addedthe story in the Abyakta book as Palatak Tuphan.He was the first science fiction writer in the Bengali language.Legacy:To commemorate his birth centenary in 1958, the JBNSTS scholarship programme was started in WestBengal. In the same year, India issued a postage stamp bearing his portrait.On September 14, 2012, Boses experimental work in millimeter-band radio was recognized as an IEEEMilestone in Electrical and Computer Engineering, the first such recognition of a discovery in India.Books:Response in the Living and Non-living , 1902Plant response as a means of physiological investigation, 1906Comparative Electro-physiology : A Physico-physiological Study, 1907Researches on Irritability of Plants , 1913Physiology of the Ascent of Sap, 1923The physiology of photosynthesis, 1924The Nervous Mechanisms of Plants, 1926Plant Autographs and Their Revelations, 1927Growth and tropic movements of plants, 1928Motor mechanism of plants, 1928

Meghnad SahaBorn: October 6, 1893, Dhaka DistrictDied: February 16, 1956, DelhiMeghnad Saha FRS was an Indian Bengali astrophysicist best known for hisdevelopment of the Saha equation ("ionization formula), used to describechemical and physical conditions in stars.He was the first director of Indian Association for the Cultivation ofScience (IACS), the oldest research institute in India.Early Life:Meghnad Saha was born on October 6, 1893 in Sheoratali, a village in theDistrict of Dacca, now in Bangladesh. He was the fifth child of his parents,Sri Jagannath Saha and Smt. Bhubaneshwari Devi.His father was a grocer in the village. Meghnad Saha had his early schooling in the primary school of thevillage. As his family could hardly able to make both ends meet, Meghnad Saha managed to pursue hisschooling only due to the generosity of a local medical practitioner, Ananta Kumar Das, who providedhim with boarding and lodging in his house.In 1905, he joined the Dhaka Collegiate School. Here he not only received a free studentship, but also astipend. However he lost both his free studentship and stipend when he participated in a boycottagainst the then British Governor of Bengal Sir Bampfylde Fuller when he came on a visit to Dacca.He took admission in the Kishorilal Jubili School and passed the Entrance Examination of the CalcuttaUniversity in 1909, standing first among the student from East Bengal obtaining the highest marks inlanguages (English, Bengali and Sanskrit combined) and in Mathematics.In 1911, he ranked third in the ISc exam while the first position went to another great scientistSatyendranath Bose.Meghnad Saha took admission in Presidency College Calcutta. In 1913 he graduated from PresidencyCollege with Mathematics major and got the second rank in the University of Calcutta while the first onewas taken by S.N. Bose.In 1915, both S.N.Bose and Meghnad Saha ranked first in M.Sc. exam, Meghnad Saha in AppliedMathematics and S.N. Bose in Pure Mathematics.While studying in Presidency College, Meghnad got involved with Anushilan Samiti to take part infreedom fighting movement. He also came in contact with nationalists like Subhash Chandra Bose andRajendra Prasad.First director of IndianAssociation for theCultivation of Science
  22. 22. Scientific CareerIn 1917, Meghnad Saha joined as lecturer at the newly opened University College of Science in Calcutta.He taught Quantum Physics. Along with S.N. Bose, he translated the papers published in German byEinstein and Minkowski on relativity into English versions.In 1919, American Astrophysical Journal published - "On Selective Radiation Pressure and itsapplication" - a research paper by Meghnad Saha.He put forward an "ionization formula" which explained the presence of the spectral lines. The formulaproved to be a breakthrough in astrophysics. He went abroad and stayed for two years. He spent time inresearch at Imperial College, London and at a research laboratory in Germany.In 1927, Meghnad Saha was elected as a fellow of Londons Royal Society.Back to IndiaMeghnad Saha moved to Allahabad and in 1932 Uttar Pradesh Academy of Science was established. Hereturned to Science College, Calcutta in 1938. During this time Saha got interested in Nuclear Physics.In 1947 he established the Indian Institute of Nuclear Physics (now known as the Saha Institute ofNuclear Physics).He took the first effort to include Nuclear Physics in the curriculum of higher studies of science. Havingseen cyclotrons used for research in nuclear physics abroad, he ordered one to be installed in theinstitute. In 1950, India had its first cyclotron in operation.He was nominated for the Nobel Prize in Physics four times- 1930, 1937, 1939, and 1940."In 1952 he stood as an independent candidate for Parliament and was elected by a wide margin. Hedied on February 16, 1956 due to a heart attack.

  30. 30. APJ Abdul KalamBorn: October 15, 1931 (age 81), DhanushkodiAvul Pakir Jainulabdeen Abdul Kalam is an Indian scientist andadministrator who served as the 11th President of India.He is a man of vision, who is always full of ideas aimed at the developmentof the country and is also often also referred to as the ‘Missile Man ofIndia’ for his work on the development of ballistic missile and launchvehicle technology.People loved and respected Dr APJ Abdul Kalam so much during his tenureas President that was popularly called the Peoples President.Kalam was elected the President of India in 2002, defeating LakshmiSahgal and was supported by both the Indian National Congress andthe Bharatiya Janata Party, the major political parties of India.He is the first Indian person to win the Hoover Prize.Early Life & EducationKalam was born on 15 October 1931 to Jainulabdeen, a boat owner and Ashiamma, a housewife,at Rameswaram, located in the South Indian state of Tamil Nadu.He came from a poor background and started working at an early age to supplement his familysincome. He was brought up in a multi-religious environment but did follow a religious routine.After completing school, Kalam distributed newspapers in order to financially contribute to his fathersincome.In his school years, he had average grades, but was described as a bright and hardworking student whohad a strong desire to learn and spend hours on his studies, especially mathematics."I inherited honesty and self-discipline from my father; from my mother, I inherited faith in goodnessand deep kindness as did my three brothers and sisters."—A quote from Kalams autobiographyAfter completing his school education at the Rameswaram Elementary School, Kalam went on toattend Saint Josephs College, Tiruchirappalli where he graduated in physics in 1954. He then movedto Madras in 1955 to study aerospace engineering at the MIT Madras, India.While Kalam was working on a senior class project, the Dean was dissatisfied with the lack of progressand threatened revoking his scholarship unless the project was finished within the next two days. Heworked tirelessly on his project and met the deadline, impressing the Dean who later said:"I [Dean] was putting you [Kalam] under stress and asking you to meet a difficult deadline".Missile Man of India
  31. 31. Career as a ScientistAfter graduating from Madras Institute of Technology (MIT – Chennai) in 1960, Kalamjoined Aeronautical Development Establishment of Defense Research and DevelopmentOrganization (DRDO) as a chief scientist.Kalam started his career by designing a small helicopter for the Indian Army, but remained unconvincedwith the choice of his job at DRDO.Kalam was also part of the INCOSPAR committee working under Vikram Sarabhai, the renowned spacescientist.In 1969, Kalam was transferred to the Indian Space Research Organization (ISRO)where he was theproject director of Indias first indigenous Satellite Launch Vehicle (SLV-III) which successfully deployedthe Rohini satellite in near earth orbit in July 1980.Joining ISRO was one of Kalams biggest achievements in life and he is said to have found himself whenhe started to work on the SLV project.Kalam first started work on an expandable rocket project independently at DRDO in 1965. In 1969,Kalam received the governments approval and expanded the program to include more engineers.In 1963–64, he visited Nasas Langley Research Center in Hampton Virginia, Goddard Space FlightCenter in Greenbelt, Maryland and Wallops Flight Facility situated at Eastern Shore of Virginia.During the period between the 1970s and 1990s, Kalam made an effort to develop the Polar SLV andSLV-III projects, both of which proved to be success.Kalam was invited by Raja Ramanna to witness the countrys first nuclear test Smiling Buddha as therepresentative of TBRL(Terminal Ballistics Research Laboratory), even though he had not participated inthe development, test site preparation and weapon designing.In the 1970s, a landmark was achieved by ISRO when the locally built Rohini-1 was launched into space,using the SLV rocket.In the 1970s, Kalam also directed two projects, namely, Project Devil and Project Valiant , which soughtto develop ballistic missiles from the technology of the successful SLV programme.Kalam and Dr. V. S. Arunachalam, metallurgist and scientific adviser to the Defense Minister, worked onthe suggestion by the then Defense Minister, R. Venkataraman on a proposal for simulataneousdevelopment of a quiver of missiles instead of taking planned missiles one by one.R Venkatraman was instrumental in getting the cabinet approval for allocating 388 crore rupees for themission, named Integrated Guided Missile Development Program (I.G.M.D.P) and appointed Kalam asthe Chief Executive.He was the Chief Scientific Adviser to the Prime Minister and the Secretary of Defence Research andDevelopment Organisation from July 1992 to December 1999.The Pokhran-II nuclear tests were conducted during this period where he played an intensive politicaland technological role. Kalam served as the Chief Project Coordinator, along with R.Chidambaram during the testing phase.
  32. 32. In 1998, along with cardiologist Dr.Soma Raju, Kalam developed a low cost Coronary stent. It wasnamed as "Kalam-Raju Stent" honouring them.In 2012, the duo, designed a rugged tablet PC for health care in rural areas, which was named as "Kalam-Raju Tablet".Tenure as President (2002-2007)Abdul Kalam served as the 11th President of India, succeeding K. R. Narayanan. He won the 2002presidential election defeating Lakshmi Sahgal. He served from 25 July 2002 to 25 July 2007.Kalam was the third President of India to have been honoured with a Bharat Ratna, Indias highestcivilian honour, before becoming the President. Dr. Sarvapali Radhakrishnan(1954) and Dr. ZakirHussain (1963) were the earlier recipients of Bharat Ratna who later became the President of India.He was also the first scientist and the first bachelor to occupy Rashtrapati Bhawan.During his term as President, he was affectionately known as the Peoples President.In his words, signing the Office of Profit Bill was the toughest decision he had taken during his tenure.Article 72 of the Constitution of India empowers the President of India to grant pardon, suspend andremit death sentences and commute the death sentence of convicts on death row.Kalam acted on only one mercy plea in his 5 year tenure as a President, rejecting the plea of rapistDhananjoy Chatterjee, who was hanged thereafter. The most important of the 20 pleas is thought to bethat of Afzal Guru, a Kashmiri terrorist who was convicted of conspiracy in the December 2001 attack onthe Indian Parliament and was sentenced to death by the Supreme Court of India in 2004. While thesentence was scheduled to be carried out on 20 October 2006, the pending action on the mercy plearesulted in him continuing in the death row.Frisking by American security authoritiesAbdul Kalam was frisked at the JFK Airport (John F. Kennedy International Airport) in New York, whileboarding a plane on 29 September 2011. He was subjected to "private screening" as he does not comeunder the category of dignitaries exempt from security screening procedures under Americanguidelines.He was frisked again after boarding the Air India aircraft with the US security officials asking for hisjacket and shoes, claiming that these items were not checked according to the prescribed proceduresduring the "private screening", despite protests from the airline crew confirming him as Indiaspresident.India threatened retaliatory action as there was a "general sense of outrage" around the country. TheIndian Ministry of External Affairs protested over this incident and a statement by the ministry said thatthe US Government had written a letter to Kalam, expressing its deep regret for the inconvenience.Kalam was previously frisked by the ground staff of the Continental Airlines at the Indira GandhiInternational Airport, New Delhi in July 2009 and was treated like an ordinary passenger, despite himbeing on the Bureau of Civil Aviation Securitys list of people exempted from security screening in India.
  33. 33. Popular CultureIn May 2011, Kalam launched his mission for the youth of the nation called the What Can I GiveMovement with a central theme to defeat corruption. He also has interests in writing Tamil poetry andin playing veenai, a South Indian string instrument.He was nominated for the MTV Youth Icon of the Year award in 2003 and in 2006.In the 2011 Hindi film I Am Kalam, Kalam is portrayed as an extremely positive influence to a poor butbright Rajasthani boy named Chhotu (role played by Harsh Mayar), who renames himself Kalam inhonour of his idol.Awards & HonoursA. P. J. Abdul Kalams 79th birthday was recognized as World Students Day by United Nations.He has also received honorary doctorates from 40 universities.The Government of India has honoured him with the Padma Bhushan in 1981 and the PadmaVibhushan in 1990 for his work with ISRO and DRDO and his role as a scientific advisor to theGovernment.In 1997, Kalam received Indias highest civilian honour, the Bharat Ratna, for his immense and valuablecontribution to the scientific research and modernization of defence technology in India.Year of Award Name of the Award Awarding Organization2012 Doctor of Laws (Honoris Causa) Simon Fraser University2011 IEEE Honorary Membership IEEE2010 Doctor of Engineering University of Waterloo2009 Hoover Medal ASME Foundation, USA2009 International von Kármán Wings Award California Institute of Technology, U.S.A2008 Doctor of Engineering (Honoris Causa)Nanyang Technological University,Singapore2007 King Charles II Medal Royal Society, U.K2007 Honorary Doctorate of Science University of Wolverhampton, U.K2000 Ramanujan Award Alwars Research Centre, Chennai[1998 Veer Savarkar Award Government of India1997 Indira Gandhi Award for National Integration Government of India1997 Bharat Ratna Government of India1990 Padma Vibhushan Government of India1981 Padma bhushan Government of India

Hargobind KhoranaBorn: January 9, 1922, RaipurDied: November 9, 2011, ConcordHar Gobind Khorana is an American molecular biologist.For his work on the interpretation of the genetic code and its function inprotein synthesis, he was awarded the Nobel Prize in the year 1968. Thisaward was, however, also shared by Robert W. Holley and MarshallWarren Nirenberg.The very same year, he received another award ‘Louisa Gross HorwitzPrize’ along with Nirenberg that was presented to them by the ColumbiaUniversity.He became a naturalized citizen of the United States in 1966 and subsequently received the NationalMedal of Science.He served as MITs Alfred P. Sloan Professor of Biology and Chemistry, Emeritus and was a member ofthe Board of Scientific Governors at The Scripps Research Institute.Khorana was born to Hindu parents in Raipur village in West Punjab, British India, currently Pakistan. Hisfather was the village "patwari" (or taxation official).He was home schooled by his father until high school. He earned his B.Sc from Punjab University,Lahore, in 1943, and his M.Sc from Punjab University, Lahore, Pakistan in 1945. In 1945, he beganstudying at the University of Liverpool.

  36. 36. Verghese KurienBorn: November 26, 1921, KozhikodeDied: September 9, 2012, NadiadVerghese Kurien was an Indian engineer and renowned socialentrepreneur, best known as the "Father of the White Revolution", forhis billion-litre idea or Operation Flood — the worlds biggestagricultural development programme.The operation took India from being a milk-deficient nation, to thelargest milk producer in the world, surpassing the USA in 1998, withabout 17 percent of global output in 2010–11, which in 30 years doubledthe milk available to every person.He founded around 30 institutions of excellence (like AMUL, GCMMF, IRMA, NDDB) which are owned,managed by farmers and run by professionals.As the founding chairman of the Gujarat Co-operative Milk Marketing Federation (GCMMF), Kurien wasresponsible for the creation and success of the Amul brand of dairy products. A key achievement atAmul was the invention of milk powder processed from buffalo milk (abundant in India), as opposed tothat made from cow-milk, in the then major milk producing nations.His achievements with the Amul dairy led Prime Minister Lal Bahadur Shastri to appoint him founder-chairman of the National Dairy Development Board (NDDB) in 1965, to replicate Amuls "Anand model"nationwide.He was also known as the "Milkman of India".Personal life:Born on 26 November 1921 at Calicut, Madras Presidency, British India (now Kozhikode, Kerala) intoa Syrian Christian family, he would later turn an Atheist. His father was a civil surgeon in Cochin (Kochi,Kerala). He went on to marry Molly, the daughter of a friend of his father.He graduated in Physics from Loyola College, Madras in 1940 and then obtained his Bachelors inmechanical engineering from the University of Madras. After completing his degree, he joined the TataSteel Technical Institute, Jamshedpur from where he graduated in 1946.He did however train for dairy technology later on, on a government sponsorship to New Zealand, abastion of cooperative dairying then, when he had to learn to set up the Amul dairy.Father of White Revolution& Milkman of India
  37. 37. Career:Kurien arrived back on 13 May 1949, after his masters degree, and was quickly deputed to theGovernment of Indias experimental creamery, at Anand in Gujarats Kheda district by the governmentand rather half-heartedly served out his bond period against the scholarship given by them. He hadalready made up his mind to quit mid-way, but was persuaded to stay back at Anand by TribhuvandasPatel (who would later share the Magsaysay with him) who had brought together Khedas farmers as acooperative union to process and sell their milk, a pioneering concept at the time.Patels sincere and earnest efforts inspired Kurien to dedicate himself to the challenging task beforethem, so much so, that when Prime Minister Jawaharlal Nehru was to visit Anand later, toinaugurate Amuls plant, he embraced Kurien for his groundbreaking work. Meanwhile, Kuriens buddyand dairy expert H. M. Dalaya, invented the process of making skim milk powder and condensed milkfrom buffalo milk instead of from cow milk.This was the reason Amul would compete successfully and well against Nestle which only usedcow milk to make them. In India, buffalo milk is the main raw material unlike Europe where cow milk isabundant.The Amul pattern of cooperatives became so successful, that in 1965 Prime Minister LalBahadur Shastri, created the National Dairy Development Board (NDDB) to replicate the programnationwide citing Kuriens "extraordinary and dynamic leadership" upon naming him chairman.As the Amul dairy experiment was replicated in Gujarats districts in the neighbourhood ofAnand, Kurien set all of them up under GCMMF in 1973 to sell the combined produce of the dairiesunder a single Amul brand.Today GCMMF sells Amul products not only in India but also overseas.He quit the post of GCMMF Chairman in 2006 following disagreement with the GCMMF management.When the National Dairy Development Board expanded the scope of Operation Flood to cover theentire country in its Phase 2 program in 1979: Kurien founded the Institute of Rural ManagementAnand (IRMA).Kuriens life story is chronicled in his memoir I Too Had a Dream.Interestingly Kurien, the person who revolutionized the availability of milk in India did not drink milkhimself.Film and its use in enlarging movement:Veteran film-maker Shyam Benegal, then an advertising executive whoed Manthan (the churning of themilk ocean).Not able to finance it, Benegal was helped by Kurien who hit upon an idea of getting each of his half amillion farmers to contribute a token two rupees for the making of the movie.
  38. 38. Manthan hit a chord with the audience immediately when it was shown in Gujarat in 1976, whichimpressed distributors to release it before audiences, nationwide.The movies success gave Kurien another idea. Like shown in the film, a vet, a milk technician and afodder specialist who could explain the value of cross-breeding of milch cattle would tour other parts ofthe country along with the films prints, to woo farmers there to create cooperatives of their own.UNDP would use the movie to start similar cooperatives in Latin America.Books:1.

  39. 39. Birbal SahniBorn: November 14, 1891, PorbandarDied: April 10, 1949, Aga Khan PalaceBirbal Sahni was an Indian paleobotanist who studied the fossils of the Indiansubcontinent, was also a geologist who took an interest in archaeology.He founded the Birbal Sahni Institute of Palaeobotany in Lucknow (U.P), India.His greatest contributions lie in the study of botany of the plants of India aswell as paleobotanyApart from writing numerous influential papers on these topics he alsoserved as the President, National Academy of Sciences, India and as anHonorary President of the International Botanical Congress, Stockholm.Early LifeThe third son of Ishwar Devi and Lala Ruchi Ram Sahani, Birbal Sahni was born in Behra, SaharanpurDistrict, West Punjab, on 14 November 1891. Among the frequent guests of his parents were MotilalNehru, Gopal Krishna Gokhale, Sarojini Naidu, and Madan Mohan Malaviya.He was also influenced into science by his grandfather who owned a banking business at Dera IsmailKhan and conducted amateur research in chemistry. He got his early education in India at GovernmentCollege University, Lahore (where his father worked) and Punjab University (1911). He learnt botanyunder S. R. Kashyap. He graduated fromEmmanuel College, Cambridge in 1914. He later studiedunder Professor A. C. Seward, and was awarded the D.Sc. degree of the University of London in 1919.In 1920 he married Savitri Suri, daughter of Sunder Das Suri who was an Inspector of Schools in Punjab.Savitri took an interest in his work and was a constant companion.CareerBirbal Sahni then came back to his native country India to work as the professor of Botany at the highlyesteemed Banaras Hindu University at the holy city of Varanasi.Sahni returned to India and served as Professor of Botany at Banaras Hindu University, Varanasiand Punjab University for about a year.He was appointed the first Professor and Head of the Botany Department of the LucknowUniversity in 1921. The University of Cambridge recognized his researches by the award of the degree ofSc. D. in 1929. In 1932 Palaeontologica Indica included his account of the Bennettitalean plant that hePioneer ofpalaeobotany
  40. 40. named Williamsonia Sewardi, and another description of a new type of petrified wood, Homoxylon,bearing resemblance to the wood of a living homoxylous angiosperm, but from the Jurassic age.Sahni maintained close relations with researchers around the globe, being a friend of Chester A. Arnold,noted American paleobotanist who later served his year in residence from 1958-1959 at the institute.He was a founder of The Paleobotanical Society which established the Institute of Palaeobotany on 10September 1946 which initially functioned in the Botany Department of Lucknow University but latermoved to its present premises at 53 University Road, Lucknow in 1949.On 3 April 1949 the Prime Minister of India Jawaharlal Nehru laid the foundation stone of the newbuilding of the Institute. A week later, on 10 April 1949, Sahni succumbed to a heart attack.HonoursSahni was recognized by several academies and institutions in India and abroad for his research.He was elected a Fellow of the Royal Society of London (FRS) in 1936, the highest British scientifichonor, awarded for the first time to an Indian botanist.He was elected Vice-President, Palaeobotany section, of the 5th and 6th International BotanicalCongresses of 1930 and 1935, respectively; General President of the Indian Science Congress for 1940;President, National Academy of Sciences, India, 1937–1939 and 1943-1944. In 1948 he was elected anHonorary Member of the American Academy of Arts and Sciences. Another high honor which came tohim was his election as an Honorary President of the International Botanical Congress, Stockholm in1950, but he died before he could serve.Contributions & InfluencesIn their book Historical perspective of early twentieth century Carboniferous paleobotany in NorthAmerica, William Darrah et al have mentioned multiple interactions of scientists with Birbal Shaniregarding fieldwork.In his speeches, former President of India Sarvepalli Radhakrishnan has mentioned Birbal Sahni inseveral contexts including science, religion etc.In the English Newspaper The Hindu, Dr. Sahni has been called Pioneer of palaeobotany (in India).In their paper "New interpretations of the earliest conifers", Rothwell have cited from Revision ofIndian fossil plants: Part III. Monocotyledons by Dr. Sahni.In their paper Seed plant phylogeny and the origin of angiosperms: An experimental cladisticapproach, Dayle and Donohogue have included sections from A petrified Williamsonia by Dr. Sahni.
  41. 41. Srinivasa RamanujanBorn: December 22, 1887, ErodeDied: April 26, 1920, ChetputSrinivasa Ramanujan was a mathematician par excellence. He is widelybelieved to be the greatest mathematician of the 20th Century. SrinivasaRamanujan made significant contribution to the analytical theory ofnumbers and worked on elliptic functions, continued fractions, and infiniteseries.Ramanujan was said to be a natural genius by the Englishmathematician G.H. Hardy, in the same league as mathematicianslike Euler and Gauss.Early LifeSrinivasa Aiyangar Ramanujan was born on December 22, 1887 in Erode, Tamil Nadu.His father worked in Kumbakonam as a clerk in a cloth merchants shop. At the of five Ramanujan wentto primary school in Kumbakonam. In 1898 at age 10, he entered the Town High School in Kumbakonam.At the age of eleven he was lent books on advanced trigonometry written by S. L. Loney by two lodgersat his home who studied at the Government college. He mastered them by the age of thirteen.Ramanujan was a bright student, winning academic prizes in high school.At age of 16 his life took a decisive turn after he obtained a book titled "A Synopsis of ElementaryResults in Pure and Applied Mathematics" by G. S. Carr. The book was simply a compilation ofthousands of mathematical results, most set down with little or no indication of proof. The bookgenerated Ramanujans interest in mathematics and he worked through the books results and beyond.By 1904 Ramanujan had begun to undertake deep research. He investigated the series (1/n) andcalculated Eulers constant to 15 decimal places. He began to study the Bernoulli numbers, although thiswas entirely his own independent discovery. He was given a scholarship to the Government College inKumbakonam which he entered in 1904. But he neglected his other subjects at the cost of mathematicsand failed in college examination. He dropped out of the college.Ramanujan lived off the charity of friends, filling notebooks with mathematical discoveries and seekingpatrons to support his work. In 1906 Ramanujan went to Madras where he entered PachaiyappasCollege. His aim was to pass the First Arts examination which would allow him to be admitted to theUniversity of Madras. Continuing his mathematical work Ramanujan studied continued fractions anddivergent series in 1908. At this stage he became seriously ill again and underwent an operation in April1909 after which he took him some considerable time to recover.Indian Mathematician
  42. 42. On 14 July 1909 Ramanujan marry a ten year old girl S Janaki Ammal.During this period Ramanujan had his first paper published, a 17-page work on Bernoulli numbers thatappeared in 1911 in the Journal of the Indian Mathematical Society. In 1911 Ramanujan approached thefounder of the Indian Mathematical Society for advice on a job. He got the job of clerk at the MadrasPort Trust with the help of Indian mathematician Ramachandra Rao.The professor of civil engineering at the Madras Engineering College C L T Griffith was interested inRamanujans abilities and, having been educated at University College London, knew the professor ofmathematics there, namely M J M Hill. He wrote to Hill on 12 November 1912 sending some ofRamanujans work and a copy of his 1911 paper on Bernoulli numbers. Hill replied in a fairly encouragingway but showed that he had failed to understand Ramanujans results on divergent series. In January1913 Ramanujan wrote to G H Hardy having seen a copy of his 1910 book Orders of infinity.Hardy, together with Littlewood, studied the long list of unproved theorems which Ramanujan enclosedwith his letter. Hardy wrote back to Ramanujan and evinced interest in his work.University of Madras gave Ramanujan a scholarship in May 1913 for two years and, in 1914, Hardybrought Ramanujan to Trinity College, Cambridge, to begin an extraordinary collaboration. Right fromthe start Ramanujans collaboration with Hardy led to important results. In a joint paper with Hardy,Ramanujan gave an asymptotic formula for p(n). It had the remarkable property that it appeared to givethe correct value of p(n), and this was later proved by Rademacher.Ramanujan had problems settling in London. He was an orthodox Brahmin and right from the beginninghe had problems with his diet. The outbreak of World War I made obtaining special items of food harderand it was not long before Ramanujan had health problems.On 16 March 1916 Ramanujan graduated from Cambridge with a Bachelor of Science by Research. Hehad been allowed to enrol in June 1914 despite not having the proper qualifications. Ramanujansdissertation was on Highly composite numbers and consisted of seven of his papers published inEngland.Illness & Return to IndiaRamanujan fell seriously ill in 1917 and his doctors feared that he would die. He did improve a little bySeptember but spent most of his time in various nursing homes. On February 18, 1918 Ramanujan waselected a fellow of the Cambridge Philosophical Society and later he was also elected as a fellow of theRoyal Society of London. By the end of November 1918 Ramanujans health had greatly improved.Ramanujan sailed to India on 27 February 1919 arriving on 13 March. However his health was very poorand, despite medical treatment, he died on April 6, 1920.In 1918, Hardy and Ramanujan studied the partition function P(n) extensively and gave a non-convergent asymptotic series that permits exact computation of the number of partitions of aninteger. Hans Rademacher, in 1937, was able to refine their formula to find an exact convergent series
  43. 43. solution to this problem. Ramanujan and Hardys work in this area gave rise to a powerful new methodfor finding asymptotic formulae, called the circle method.He discovered mock theta functions in the last year of his life. For many years these functions were amystery, but they are now known to be the holomorphic parts of harmonic weak Maass forms.Ramanujan’s NotebookWhile still in Madras, Ramanujan recorded the bulk of his results in four notebooks of loose leaf paper.These results were mostly written up without any derivations.Mathematician Bruce C. Berndt, in his review of these notebooks and Ramanujans work, says thatRamanujan most certainly was able to make the proofs of most of his results, but chose not to.The first notebook has 351 pages with 16 somewhat organized chapters and some unorganized material.The second notebook has 256 pages in 21 chapters and 100 unorganised pages, with the third notebookcontaining 33 unorganised pages. The results in his notebooks inspired numerous papers by latermathematicians trying to prove what he had found. Hardy himself created papers exploring materialfrom Ramanujans work as did G. N. Watson, B. M. Wilson, and Bruce Berndt. A fourth notebook with 87unorganised pages, the so-called "lost notebook", was rediscovered in 1976 by George Andrews.Ramanujan – Hardy Number 1729The number 1729 is known as the Hardy–Ramanujan number after a famous anecdote of the Britishmathematician G. H. Hardy regarding a visit to the hospital to see Ramanujan. In Hardys words:“ I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number1729 and remarked that the number seemed to me rather a dull one, and that I hoped it wasnot an unfavorable omen. "No," he replied, "it is a very interesting number; it is the smallestnumber expressible as the sum of two cubes in two different ways. ”The two different ways are1729 = 13+ 123= 93+ 103.Generalizations of this idea have created the notion of "taxicab numbers". Coincidentally, 1729 isalso a Carmichael number.RecognitionRamanujans home state of Tamil Nadu celebrates 22 December (Ramanujans birthday) as State ITDay, memorializing both the man and his achievements, as a native of Tamil Nadu.A stamp picturing Ramanujan was released by the Government of India in 1962 – the 75th anniversaryof Ramanujans birth – commemorating his achievements in the field of number theory, and a newdesign was issued on December 26, 2011, by the India Post.
  44. 44. Since the Centennial year of Ramanujan, every year 22 Dec, is celebrated as Ramanujan Day bythe Government Arts College, Kumbakonam where he had studied and later dropped out.On the 125th anniversary of his birth, India declared the birthday of Ramanujan, December 22, asNational Mathematics Day. The declaration was made by Dr. Manmohan Singh in Chennai onDecember 26, 2011. Dr Manmohan Singh also declared that the year 2012 would be celebrated asthe National Mathematics Year.In popular CultureA film, based on the book The Man Who Knew Infinity: A Life of the Genius Ramanujan by RobertKanigel, is being made by Edward Pressman and Matthew Brown with R. Madhavan playingRamanujan.Another international feature film on Ramanujans life was announced in 2006 as due to beginshooting in 2007. It was to be shot in Tamil Nadu state and Cambridge and be produced by an Indo-British collaboration and co-directed by Stephen Fry and Dev Benegal. A play, First Class Man byAlter Ego Productions, was based on David Freemans First Class Man. On 16 October 2011, it wasannounced that Roger Spottiswoode, best known for his James Bond film Tomorrow Never Dies, isworking on the film version, starring actor Siddharth. Like the book and play it is also titled The FirstClass Man; the films scripting has been completed and shooting is being planned from 2012.A Disappearing Number is a recent British stage production by the company Complicite thatexplores the relationship between Hardy and Ramanujan.The novel The Indian Clerk by David Leavitt explores in fiction the events following Ramanujansletter to Hardy.On 22 March 1988, the PBS Series Nova aired a documentary about Ramanujan, "The Man WhoLoved Numbers"Ramanujan is mentioned in the Hollywood Blockbuster Good Will Hunting starring Matt Damon afilm based on an orphan genius living in the rough part of South Boston.
  45. 45. Ganapathi ThanikaimoniBorn: January 1, 1938, ChennaiDied: September 5, 1986, KarachiGanapathi Thanikaimoni, a successful botanist of his days, is remembered tilldate for his widespread contribution in the field of palynology. His researchesand projects not only helped India to make its presence felt on the world stageof botany, it also furthered public relations between two countries. GanapathiThanikaimoni gradually established himself in the role of Indias ambassador toother countries to promote the research made in botany in our country. Thani, as he fondly came to beknown as, specialized in the research of pollen morphology and phylogeny of the palm tree. Aftercompleting his preliminary education in Madras, Ganapathi Thanikaimoni visited Pondicherry to earn hisdoctorate degree. His research work is still held in high regard. A project that he had started and whichhad to be put on hold because of his untimely demise is still being pursued by the French Institute inPondicherry.Early Life & EducationGanapathi Thanikaimoni was born on New Years Day in the year 1938 in Madras. He spent his entirechildhood in the city of Madras and passed his school and college years from the same. Madras, at thattime, was very important geographically, because of the proximity of ports. He earned a Masters ofScience degree in Botany from the University of Madras in the year 1962. Ganapathi Thanikaimoni wastaking lessons under Professor B G L Swamy, a famous plant morphologist during that time in theUniversity of Madras. It was in the same year that he received the Fyson Prize for his contribution in thefield of natural science. It was after his college years that Ganapathi Thanikaimoni started work on hisresearch paper that eventually earned him a doctorate degree from the University of Montpellier. In1970, the University authorities decided to grant him the doctorate degree because of his research inpollen morphology and the classification of the evolutionary stages of the palm tree.CareerArmed with a doctorate degree from the University of Montpellier and the Fyson Prize, GanapathiThanikaimoni went ahead to establish himself as a botanist. He joined as a scientist at the FrenchInstitute of Pondicherry, joining the palynology laboratory that was set up inside the institute in the year1960.Thani worked in Pondicherry under the guidance of Dr Professor Guinet. His hard work and dedicationwere soon identified by the teachers at the institute, who did not waste time to promote Thani to thepost of director of the palynology laboratory. Reports claim that Ganapathi Thanikaimoni was not onlyscientifically sound, but also very organized in his work. It was his administrative capabilities coupled
  46. 46. with his huge store of learning that drew the attention of all his seniors and teachers at the FrenchInstitute of Pondicherry.During his initial years at the French Institute of Pondicherry, Thani worked on the Clusiaceae, Araceae,Mimosaceae, Menispermaceae and Sonnera species of plants. His researches with the enlisted specieswere published in journals that were brought out by the French Institute of Pondicherry from time totime. Though Ganapathi Thanikaimoni worked on a particular set of species within the plant kingdomand based his research on the pollen morphology of this species, he did not flinch from working on allother plants from the large collection in the plant kingdom as well. Thani insisted that all species mustbe studied if accurate results are to be achieved for a particular set of plants because behavioralpatterns of different species are interrelated.Thani never believed in limiting his research work to only the modern flora. Although pollen morphologyas done by him chiefly dealt with the pollen of modern flora, he made it a point to extend his researchto fossil pollen as well. It was on the insistence of Thani that a tertiary pollen study was organized at the7th IPC held in Brisbane, Australia. In the year 1972, he received worldwide recognition when hiscompilation of morphology of angiosperm pollen was published as the Index Bibliographique sur laMorphologic des Pollens dAngiospermes. This introduced his studies to a worldwide audience. In theyear 1983, as a representative of the French Institute of Pondicherry, Ganapati Thanikaimoni becamethe head of a workshop that was held in Pondicherry to share botany concepts and pollen morphologyideas with Indian and French palynologists. Thani studied the pollen of plants derived from regions inAfrica and India. He had a collection of about 20,000 slides of tropical palynomorphs, which were usedfor further research work.Role in SocietyDr Ganapathi Thanikaimoni was not only involved in the study of pollen, but also tried his best tocontribute to the wellbeing of the society. Thani tried his best to educate government authorities totake proper care of coastlines and to rehabilitate arid areas across India. It is well known that mangrovesplay a very important role in balancing the eco system; therefore Thani took steps to educate the societyand the government on the necessity of a mangrove. He was also one of the masterminds in theUNESCO developed Asia and Pacific Mangrove Project.
