Egyptians Mathmatics 2000-1800 B.C.
1.)It is thought that the Egyptians introduced the earliest fully-developed base 10 numeration system at least as early as 2700 BCE (and probably much early) 2.)Often rounded off to the higher power, written in hieroglyphs, but they had no concept of a place-valued system such as the decimal system is. -
2000 BCE
Babylon 2000 B.C.- 500 B.C.
1.)The Babylonians replaced the older (4000 BC - 2000 BC) Sumerian civilization around 2000 BC. The Sumerians had already developed writing (uniform on clay tablets) and arithmetic (using a base 60 number system). 2.)The Babylonians adopted both of these. But, Babylonian math went beyond arithmetic, and developed basic ideas in number theory, algebra, and geometry. 3.)Some of their methods were rules that solved specialized quadratic, and even some cubic, equations. -

Egyptian Numerals 2000-1800 B.C
1.)1 is shown by a single stroke.
2.)10 is shown by a drawing of a hobble for cattle.
3.)100 is represented by a coil of rope.
4.)1,000 a drawing of a lotus plant.
5.)10,000 is represented by a finger.
6.)100,000 a tadpole or frog
7.)1,000,000 figure of a god with arms raised above his head. -

Rhind Papyrus 1650 B.C.
1.)The Rhind Papyrus, dating from around 1650 BCE, is a kind of instruction manual in arithmetic and geometry, and it gives us explicit demonstrations of how multiplication and division was carried out at that time. 2.)The Rhind Papyrus dates from approximately 1650 B.C.E. Mr. A. Henry Rhind, a Scottish lawyer, visited Egypt in the mid-nineteenth century on the advice of his physician in hopes that its dry climate would be beneficial to his poor health -
1500 BCE
India 1500 B.C.- 200 B.C.
1.)These are appendices to the Vedas, and give rules for constructing sacrificial altars. To please the gods, an altar's measurements had to conform to very precise formula, and mathematical accuracy was very important. 2.) It is not historically clear whether this mathematics was developed by the Indian Vedic culture, or whether it was borrowed from the Babylonians. -

Classical Geometry 600 B.C.- 400 A.D.
1.)Thales Miletus was one of the Seven pre-Socratic Sages, and brought the science of geometry from Egypt to Greece. He is credited with the discovery of five facts of elementary geometry, including that an angle in a semicircle is a right angle (referred to as “Thales Theorem”). But some historians dispute this and give the credit to Pythagorus. There is no evidence that Thales used logical deduction to prove geometric facts. -
570 BCE
Pythagorean Theorem 570-495 B.C.
1.)The sum of the areas of the two squares on the legs (a and b) equals the area of the square on the hypotenuse (c) -
330 BCE
Chinese Geometry 100-1400 B.C
1.)The first definitive work and the oldest in existence on the geometry of China was the ‘Mo Jing’. It was a compilation of work done by philosopher Mozi, produced after his death around 330BC. -
201 BCE
Hellenistic Geometry 201- 300 A.D.
1.)Among the best known and most influential mathematicians who studied and taught at Alexandria were Euclid, Archimedes, Eratosthenes, Heron, Menelaus and Diophanus. 2.)During the late 4th and early 3rd Century BCE, Euclid was the great chronicler of the mathematics of the time, and one of the most influential teachers in history. -

Islamic Geometry 10th century
1.) A binomial is a simple type of algebraic expression which has just two terms which are operated on only by addition, subtraction, multiplication and positive whole-number exponents, such as (x + y)2. -

Islamic Geometry
1.)Persian astronomer, scientist and mathematician Nasir Al-Din Al-Tusi was perhaps the first to treat trigonometry as a separate mathematical discipline
2.)Major mathematical contributions was the formulation of the famous law of sines for plane triangles -
17th Century
1.)In the wake of the Renaissance, the 17th Century saw an unprecedented explosion of mathematical and scientific ideas across Europe, a period sometimes called the Age of Reason. 2.)The invention of the logarithm in the early 17th Century by John Napier (and later improved by Napier and Henry Briggs) contributed to the advance of science, astronomy and mathematics by making some difficult calculations relatively easy. -
18th Century
1.)The period was dominated, though, by one family, the Bernoulli’s of Basel in Switzerland, which boasted two or three generations of exceptional mathematicians, particularly the brothers, Jacob and Johann. 2.) His “Elements of Geometry”, a re-working of Euclid’s book, became the leading geometry textbook for almost 100 years. -
19th Century
1.)Later in life, Gauss also claimed to have investigated a kind of non-Euclidean geometry using curved space but, unwilling to court controversy, he decided not to pursue or publish any of these avant-garde ideas. 2.)This left the field open for János Bolyai and Nikolai Lobachevsky (respectively, a Hungarian and a Russian) who both independently explored the potential of hyperbolic geometry and curved spaces. -
20th Century
1.)determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels. -
Fractal theorem 20th century
1.)A fractal is a natural phenomenon or a mathematical set that exhibits a repeating pattern that displays at every scale. It is also known as expanding symmetry or evolving symmetry. -
Present-Day Geometry
1.)Modern day geometry has made developments in a number of areas, including those that make use of the raw computing power of today’s computers. -
