LIFE AND CONTRIBUTIONS OF ERNEST RUTHERFORD
Ernest Rutherford was born in New Zealand in 1871 and studied at the University of New Zealand, earning his DSc in 1900. He made pioneering discoveries about the structure of the atom, discovering alpha and beta radiation emitted by uranium and defining them as positively charged atomic particles. Rutherford's gold foil experiment led him to deduce that atoms have a small, dense nucleus containing their mass, around which electrons orbit. He was awarded the Nobel Prize in Chemistry in 1908 and held prestigious positions including as President of the Royal Society.
Subrahmanya chandrashekar1
Subrahmanyan Chandrasekhar was born in 1910 in India. He received his early education in India and received his PhD from Cambridge University in 1933. In 1930, he discovered the Chandrasekhar limit, which established the maximum mass that can be supported by the pressure of electrons in a white dwarf star. This discovery led to the later discoveries of neutron stars and black holes. Throughout his career, Chandrasekhar made seminal contributions to the fields of stellar structure and evolution. He was awarded the Nobel Prize in Physics in 1983 for his work on stellar structure and evolution. Chandrasekhar passed away in 1995 at the age of 84.
Ernest Rutherford
Ernest Rutherford was a nuclear physicist born in 1871 in New Zealand who made several groundbreaking discoveries about the structure of atoms and radioactive decay. He studied at the University of New Zealand and conducted research that led to his first major science prize in 1904. Some of Rutherford's key discoveries included discovering the radioactive gas radon in 1897, proposing the nuclear model of the atom in 1911 which described the atom's nucleus, and predicting the existence of neutrons in 1920. Rutherford was knighted in 1914 and became the first person to successfully achieve nuclear transmutation by transforming nitrogen into oxygen in 1917.
Ernest Rutherford
Ernest Rutherford conducted an experiment in 1911 where he fired positively charged alpha particles at a thin gold foil. Contrary to expectations, many particles were deflected or bounced back, showing that the atom's mass was concentrated in a small nucleus rather than evenly distributed as Thomson's plum pudding model predicted. This led Rutherford to propose the nuclear model of the atom, with electrons orbiting a dense central nucleus, revolutionizing the field of nuclear physics.
Ernest rutherford
Ernest Rutherford was a New Zealand-British chemist and physicist known as the father of nuclear physics. He coined the terms alpha and beta rays to describe two types of radiation emitted by thorium and uranium. Rutherford's research with Frederick Soddy established that radioactive elements can transform into other elements. He later demonstrated that alpha particles could be directed through thin metal sheets, laying the foundation for future particle physics experiments. Rutherford made many contributions to the field of nuclear physics and has had numerous institutions, awards, and places named in his honor.

This document provides biographical information about the English chemist and physicist John Dalton. It describes that Dalton was born in 1766 in Cumberland, England into a Quaker family. As a young man, he helped his brother run a Quaker school. He was influenced by his friend Elihu Robinson, an instrument maker and meteorologist, which sparked his interests in mathematics and meteorology. The document outlines Dalton's contributions including his research on color blindness, for which the term "Daltonism" was coined, as well as his work on the reflection and refraction of light. It describes Dalton's atomic theory which proposed that elements are made of atoms and that atoms of different elements have different weights. The document also notes some
life and works of 5 great personalities from different fields
Ernest Rutherford was a New Zealand physicist known as the father of nuclear physics. He discovered the concept of radioactive half-life and differentiated alpha and beta radiation while working at McGill University. Later experiments at the University of Manchester proved that alpha radiation is helium nuclei. Rutherford is most famous for his 1911 gold foil experiment which led to his proposal of the Rutherford model of the atom with a small, dense nucleus. He conducted the first nuclear reaction splitting an atom in 1917.
Pioneers
The document summarizes the contributions of several pioneers of nuclear technology, including:
- Henri Becquerel discovered spontaneous radiation in 1896 and won the 1903 Nobel Prize along with the Curies. Marie Curie won two Nobel Prizes, discovering radium and polonium.
- Ernest Rutherford discovered alpha and beta rays in 1899 and the theory of radioactive decay with Soddy in 1901. He received the 1908 Nobel Prize.
- Niels Bohr published the theory combining nuclear theory with quantum theory in 1913.
- Einstein gave the theories of relativity and E=mc2, receiving the 1921 Nobel Prize for the photoelectric effect.
Development of the periodic table
The document summarizes the development of the periodic table over time by various scientists from the 17th century to today. Dmitri Mendeleev produced one of the first recognizable periodic tables in 1869, arranging elements based on atomic weight and leaving gaps for undiscovered elements. Later, Henry Moseley determined that arranging elements by atomic number instead of weight gave a better organization, and scientists like Glenn Seaborg continued discovering new elements that were added to the table. The periodic table is now a fundamental tool that organizes all the known elements according to their atomic structure.
The periodic table
1. Johann Döbereiner noticed that the atomic weight of strontium fell between calcium and barium, elements with similar properties, proposing the Law of Triads.
2. John Newlands classified elements into groups and noted pairs differed by multiples of eight in atomic weight, proposing the Law of Octaves.
3. Dmitri Mendeleev developed the first recognizable periodic table, ordering elements by atomic mass and predicting undiscovered elements, though Henry Moseley later showed atomic number was fundamental.
Marie curie – discoverer of radioactive elements
Marie Curie was a Polish physicist and chemist born in 1867 who made groundbreaking discoveries in the field of radioactivity. She coined the term radioactivity and discovered the radioactive elements polonium and radium. Curie received numerous honors, including being the first person to receive two Nobel Prizes, for her scientific achievements. Radioactivity is the process by which unstable atomic nuclei emit radiation as they decay into more stable forms, and the rates of radioactive decay are expressed in half-lives, the time it takes for half of a radioactive substance to decay.
Pres discovery & invention
The document provides examples of descriptions of inventions and discoveries. It describes Whitcomb Judson's invention of the zipper in 1893. It also summarizes the discovery of radioactivity by Antoine Henri Becquerel in 1896, when he discovered that uranium salts emitted invisible and penetrating rays capable of exposing photographic plates even in the dark. Additionally, it discusses the discovery of DNA in the early 1950s by Francis Crick and James Watson at Cambridge University and Maurice Wilkins and Rosalind Franklin at King's College in London.
The history of the earth
The document summarizes key aspects of the formation and history of the solar system and Earth. It discusses:
- The accepted nebular hypothesis model for the origin of the solar system over 4.5 billion years ago.
- How radiometric dating methods show the Earth formed 4.55 billion years ago by accretion of elements in the solar nebula, with its core, mantle, and crust separating as it cooled.
- How fossils found in rocks of different eras provide temporal and paleoecological information about the changing Earth and life over geologic time.
- The theories of catastrophism and uniformitarianism explaining sudden versus gradual changes shaping the Earth's surface and climate over millions of years
Discovery of atom
The Indians first attempted to discover atoms in the 6th century BCE, referring to the smallest particle as "anor". Several scientists like Lavoisier, Kekule, and Mendeleev attempted to organize the elements into a periodic table. Dmitri Mendeleev is generally credited with inventing the periodic table of chemical elements in 1869, arranging them into a table to illustrate recurring trends in their properties. The periodic table layout has been refined over time as new elements were discovered and new theoretical models explained chemical behavior. Safety tips are provided like not experimenting carelessly in the chemistry lab and maintaining clear concepts to build a strong foundation.
James Chadwick
James Chadwick was a British physicist born in England. He studied under Ernest Rutherford and worked with him on experiments involving radioactive substances. This led Chadwick to continue Rutherford's idea that there were neutral particles in the nucleus of an atom. Through his own experiment in 1932, Chadwick was able to prove the existence of the neutron. He called these neutral particles "neutrons" and showed they have about the same mass as a proton but no electric charge. This discovery of the neutron was fundamental to modern physics and earned Chadwick the 1935 Nobel Prize in Physics.
Tell A Story The Periodic Table
The development of the periodic table occurred over many decades as scientists discovered elements and recognized patterns in their properties. Early proposals included Dobereiner's law of triads in 1829 and Newlands' law of octaves in 1863. However, Dmitri Mendeleev is considered the father of the periodic table for his 1869 table that predicted undiscovered elements. Later, noble gases like argon were discovered and placed on the table. The modern periodic table was influenced by discoveries of atomic structure and isotopes that explained the periodic recurrence of properties.
Discovery of neutron
Sir James Chadwick discovered the neutron in 1932. He was awarded the 1935 Nobel Prize in Physics for this discovery. Chadwick performed an experiment where he smashed alpha particles into beryllium and allowed the radiation to hit paraffin wax. The results showed collisions with beryllium atoms released massive neutral particles, which Chadwick named neutrons. Neutrons have the same mass as protons but have no charge. Chadwick's discovery of the neutron helped reveal properties of atomic nuclei.
Chadwick
James Chadwick was a British physicist born in 1891 who is known for discovering the neutron. He received several honors for his work, including the Nobel Prize in Physics in 1935. Chadwick served in World War I and was a prisoner of war. He also participated in the Manhattan Project during World War II. Chadwick's model of the atom focused on neutrons, differing from Niels Bohr's model which depicted electrons in rings. Both models showed the structure of the atom but represented it differently.
Chemists and their contributions (Technovators)
The document provides biographical information on numerous chemists from both foreign and local backgrounds. Some of the notable chemists mentioned include Dmitri Mendeleev, who developed the periodic table of elements; Izaak Kolthoff, considered the "Father of Analytical Chemistry"; and Antoine Lavoisier, known as the "father of modern chemistry". The document also profiles the contributions of chemists such as Julian Banzon from the Philippines, who studied using coconut oil and natural plants as renewable resources.
The Historical Development of Atomic Models
The document traces the historical development of atomic models from ancient Greek philosophers Democritus and Leucippus proposing the first idea of atoms, to J.J. Thomson discovering the electron in 1903 and proposing atoms have a positively-charged sphere with electrons embedded, to Rutherford discovering the proton in 1911 and proving atoms have a nucleus, to Bohr solving problems with his 1913 model of electrons moving in shells around the nucleus, to Chadwick discovering the neutron in 1932 and establishing the modern nuclear model of the atom with protons and neutrons in the nucleus surrounded by electrons.

- Albert Einstein developed the theories of relativity and made important contributions to quantum mechanics.
Chemist in the development of an atom
The document traces the development of the atomic model from ancient Greek philosophers to modern quantum mechanics. Thales of Miletus first proposed that all matter comes from water, while Democritus suggested matter is made of indivisible atoms. John Dalton adopted Democritus' idea of atoms in the early 1800s and founded atomic theory. Niels Bohr then suggested atoms have a planetary structure with electrons orbiting the nucleus like planets around the sun. Finally, quantum mechanics models like Schrodinger's wave equation describe electrons as existing in quantized energy levels or orbitals within atoms.
History of radio
- The document traces the history of key discoveries and innovations in radio technology from the 18th century to the early 20th century, including Orsted's discovery of electromagnetism, Ampere's work building on this, Faraday's discovery of electromagnetic induction, and Maxwell's unification of electricity, magnetism and light into electromagnetic theory.
- It discusses early pioneers of radio including Hertz, Branly, Tesla, Bose and their experiments transmitting radio waves wirelessly. Marconi is noted for establishing the first commercial radio telegraph system in the late 1890s. However, the invention of radio involved contributions from many scientists over decades.
Matter and the Atomic Theory
This document discusses the atomic theory and properties of the three states of matter. It covers key scientists and their contributions, including Dalton formulating the atomic theory, Thomson discovering the electron, Rutherford naming the types of radiation, and Bohr proposing electron orbitals. The three states of matter - solid, liquid, gas - are compared in terms of particle motion and forces. Phase changes like melting, freezing and evaporation are explained. The development of the modern atomic model and discovery of subatomic particles like the proton and neutron are also summarized.

The atom (handouts)
1. Theories of atomic structure have evolved over millennia from ancient Greek philosophers to modern scientific experiments. John Dalton proposed atoms as the basic building blocks of matter in 1803 based on laws of chemical combination.
2. In the early 20th century, experiments revealed atoms have smaller subatomic particles including electrons, protons, and neutrons. Ernest Rutherford's gold foil experiment in 1911 established that atoms have a small, dense nucleus containing positively charged protons and uncharged neutrons, with electrons in orbits around the nucleus.
3. Niels Bohr's 1913 model visualized electrons orbiting the nucleus like planets around the sun, which explained atomic spectra. Later models like Erwin Schrödinger's 1926

Microbial interaction
Microorganisms interacts with each other and can be physically associated with another organisms in a variety of ways.
One organism can be located on the surface of another organism as an ectobiont or located within another organism as endobiont.
Microbial interaction may be positive such as mutualism, proto-cooperation, commensalism or may be negative such as parasitism, predation or competition
Types of microbial interaction
Positive interaction: mutualism, proto-cooperation, commensalism
Negative interaction: Ammensalism (antagonism), parasitism, predation, competition
I. Mutualism:
It is defined as the relationship in which each organism in interaction gets benefits from association. It is an obligatory relationship in which mutualist and host are metabolically dependent on each other.
Mutualistic relationship is very specific where one member of association cannot be replaced by another species.
Mutualism require close physical contact between interacting organisms.
Relationship of mutualism allows organisms to exist in habitat that could not occupied by either species alone.
Mutualistic relationship between organisms allows them to act as a single organism.
Examples of mutualism:
i. Lichens:
Lichens are excellent example of mutualism.
They are the association of specific fungi and certain genus of algae. In lichen, fungal partner is called mycobiont and algal partner is called
II. Syntrophism:
It is an association in which the growth of one organism either depends on or improved by the substrate provided by another organism.
In syntrophism both organism in association gets benefits.
Compound A
Utilized by population 1
Compound B
Utilized by population 2
Compound C
utilized by both Population 1+2
Products
In this theoretical example of syntrophism, population 1 is able to utilize and metabolize compound A, forming compound B but cannot metabolize beyond compound B without co-operation of population 2. Population 2is unable to utilize compound A but it can metabolize compound B forming compound C. Then both population 1 and 2 are able to carry out metabolic reaction which leads to formation of end product that neither population could produce alone.
Examples of syntrophism:
i. Methanogenic ecosystem in sludge digester
Methane produced by methanogenic bacteria depends upon interspecies hydrogen transfer by other fermentative bacteria.
Anaerobic fermentative bacteria generate CO2 and H2 utilizing carbohydrates which is then utilized by methanogenic bacteria (Methanobacter) to produce methane.
ii. Lactobacillus arobinosus and Enterococcus faecalis:
In the minimal media, Lactobacillus arobinosus and Enterococcus faecalis are able to grow together but not alone.
The synergistic relationship between E. faecalis and L. arobinosus occurs in which E. faecalis require folic acid

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
