Published on

History of Math is a project in which students worked together in learning about historical development of mathematical ideas and theories. They were exploring about mathematical development from Sumer and Babylon till Modern age, and from Ancient Greek mathematicians till mathematicians of Modern age, and they wrote documents about their explorations. Also they had some activities in which they could work "together" (like writing a dictionary, taking part in the Eratosthenes experiment, measuring and calculating the height of each other schools, cooperating in given tasks) and activities that brought out their creativity and Math knowledge (making Christmas cards with mathematical details and motives and celebrating the PI day). Also they were able to visit Museum, exhibition "Volim matematiku" and to prepare (and lead) workshops for the Evening of mathematics (Večer matematike). At the end they have presented their work to other students and teachers.

  20. 20.  Our first knowledge of math comes from Egypt and Babylon  Babylon math dates back to 4000 BC along with the Sumerians in Mesopotamia
  21. 21.  Little is known about Sumer  It was first inhabited 4500 and 4000 BC  Today, these people are called Ubaidiansi  Even less is known about their math
  22. 22.  They used cuneiform and wrote on clay tablets  They used over 2000 signs Picture 1. Sumerian cuneiform record
  23. 23.  They developed heksagezimal number system which was taken by the Babylonians  Babylonians, Assyrians and Hiti inherited Sumerian law and literature and more importantly their way of writing  What we have kept from the Sumerians today is the division of weeks to 7 days, days to 24 hours, 60 minutes in an hour and 60 seconds in one minute
  24. 24.  With the collapse of the Sumerian civilization in Mesopotamia Babylon is developed  They inherited from the Sumerians cuneiform and heksagezimal number system Picture 2. The digits of the Babylonian number system
  25. 25.  They used 2 basic forms for numbers:  They had no symbol for zero or a decimal point, so it was difficult to interpret the findings from this era Picture 3. Babylonian symbol for the number 10 Picture 4. Babylon symbol for number 1 or 60

  63. 63. • in the second millennium BC China had symbols for numbers • they counted with sticks until abacus appeared in the 16th century Picture 1. chinese numbers Picture 2. abacus • not much is known about the mathematics of ancient China, but it is fairly certain that the origins of astronomy and mathematics of ancient China date back to at least the second millennium BC, at that time the Chinese have already had an elaborate calendar • oldest surviving mathematical texts originate from the time around 200 BC
  64. 64. • Contributions of Chinese mathematicians: • The Holy Book of arithmetic (2nd - 12th century) - indirect talks about the Pythagorean theorem • Arithmetic in nine books (about 150 BC) - the process of calculating the area of a triangle, rectangle, circle, circular section and clip, the volume of prism, pyramid, cylinder, cone, deprived (truncated) cone and pyramid • The book of phases (I Ching) - one of the oldest surviving book - used for fortune telling and divination, contains elements of the binary notation of numbers
  65. 65. • The famous mathematicians: • Zhang Qiu Jian (5th c.) - Gave the formula for the sum of the arithmetic series • Tsu Chung - chih (430 to 500) - the value of the number π takes a precise six decimal places • Quin Jiu - Shao (1202 -1261) - Sought the solution of equations method that is called Horner (William Horner, 1819), although it was known in China 500 years earlier • Chu Shih - kieh (1270 -1330) - wrote two important texts that are the pinnacle of Chinese mathematics texts which contain Pascal's triangle binomial coefficients, which is known in China for four centuries before it was discovered by Pascal.
  66. 66. INDIAN MATHEMATICS
  67. 67. • in ancient Indian mathematics there is no great works exclusively devoted to mathematics; mathematics is present only as part of, as a separate chapter in astronomical or astrological works • the oldest known mathematical texts are Sulvasutre, accessories to religious texts  in them are the rules for measuring and building temples and altars at the level of elementary geometry • characteristics of Indian mathematical texts is that they are generally written in verse Picture 1. Indian numbers
  68. 68. Ancient India mathematics: • Aryabhatta (476 to 550) - he knew how to take out the second and third root of the division into groups of radikands • gave the correct formula for the area of a triangle and a circle, writes about quadratic equations and potencies • Brahmagupta (598 – about 670) • Brahmaguptas formula: a generalization of Heron's formula in the cyclic quadrilateral;
  69. 69. • Mahavira (9th century) - dealt with elementary mathematics and the first Indian mathematician who wrote the only math dedicated text • Bhaskara (1114 – 1185) - the most famous Indian mathematician to the 12th century, has contributed to the understanding of numerical systems and solving equations and proved the Pythagorean theorem • his main mathematical works of Lilavati and Bijaganita, dealt with plane and spherical trigonometry
  70. 70. Arab mathematics
  71. 71. • Today's western style math is much more similar to what we find in the Arab mathematics than that of ancient Greeks, many of the ideas that have been attributed to the Europeans proved to be actually Arabic Picture 1. Arabic numbers Al-Khwarizmi (780 – 850) first great Arab mathematician
  72. 72. Arabic mathematicians: • Al-Karaji (953 - 1029) - is considered the first person who completely freed algebra from geometrical operations and replaced them with arithmetic • founded the influential algebraic school that will work successfully for centuries •Al-Khwarizmi (780 - 850 ) first great Arab mathematician • he wrote about algebra, geometry, astronomy and he introduced Arabic numerals in mathematics • he dealt with linear and square equations. He built tables for sinus and tangens functions. He gave a general method for finding two roots of quadratic equations : 𝑎𝑥2 + 𝑏𝑥 + 𝑐 = 0 𝑥1,2 = −𝑏 ± 𝑏2 − 4𝑎𝑐 2𝑎
  73. 73. • Al-Haytham (965 - 1040) is probably the first who attempted to classify the even perfect numbers • also was the first person that has imposed Wilson's theorem (if p is prime, then p divides 1 + (p - 1)!), it is unclear if he knew how to prove it • Omar Khayyam (1048 – 1131) with mathematics also dealt with astronomy, philosophy and poetry • gave a complete classification of cubic equations (14 types) and the first to notice that you do not need to have a unique solution • Nasir al-Din al-Tusi (1201 - 1274) wrote important works on logic, ethics, philosophy, mathematics and astronomy • The most important contribution was his creation of trigonometry as a mathematical discipline, not a means of astronomical calculations, and gave the first complete account of plane and spherical trigonometry. • This work gave the theorem of the sinuses for planar triangles: 𝑎 sin 𝛼 = 𝑏 sin 𝛽 = 𝑐 sin 𝛾

  95. 95. Biography  Blaise Pascal was a French mathematician, physicist, inventor, writer and Christian philosopher. He was a 'child prodigy' and was educated by his father.  Pascal’s earliest jobs were in applied and natural sciences, where he contributed to the study of fluids, and clarified the concepts of pressure and vacuum by generalizing the work of EvangelistaTorricelli.
  96. 96.  Pascal's first calculating machine
  97. 97. Pascal’s contribution to math  The first significant work, Blaise wrote at age sixteen, and it was a basic draft of his famous debate on the sections of the cone.
  98. 98.  Blaise Pascal, also created his famous  mystical hexagram (Pascal's theorem), which has not survived.  In his 'Treatise on the arithmetical triangle' '(Traité du triangle arithmétique), described the convenient, practical tabulation of binomial coefficients, now called "Pascal's Triangle'.
  99. 99. Pascal’s contribution to physics  His work in the field of hydrodynamics and hydrostatics has focused on the principles of hydraulic fluids. His inventions include the hydraulic press (using hydraulic pressure to multiply force) and the syringe.  Hydrostatic pressure increases the depth, acts equally in all directions and is equal in all places at the same depth.
  100. 100.  Pascal’s law  The fundamental law of hydrostatics:  The fluid contained in a closed vessel outer pressure p expands equally in all directions, that is, particles of the liquid pressure is transmitted equally in all directions.
