**There's no way to be sure**, but anthropologists generally agree that the circle was created long before history was recorded. And, the Greeks considered the Egyptians to be the inventors of geometry.

Prof. Ishikawa does not need any introduction. He is known the world over as the Father of Quality Circles.

16. The first theorems relating to circles are attributed to Thales around 650 BC.

x2 + y2 = r2 , and this is the equation of a circle of radius r whose centre is the origin O(0, 0). The equation of a circle of radius r and centre the origin is x2 + y2 = r2 .

A circle is named by its center. Thus, the circle to the right is called circle A since its center is at point A. Some real world examples of a circle are a wheel, a dinner plate and (the surface of) a coin. The distance across a circle through the center is called the diameter.

All of these were approximations of measurements that compared the circumference of a circle to its diameter. Around 250 BC, a brilliant mathematician by the name of Archimedes of Syracuse became interested in an idea developed by his compatriots a hundred years or so earlier.

"Zero and its operation are first defined by [Hindu astronomer and mathematician] Brahmagupta in 628," said Gobets. He developed a symbol for zero: a dot underneath numbers.

Archimedes is known as the Father Of Mathematics. He lived between 287 BC – 212 BC. Syracuse, the Greek island of Sicily was his birthplace. Archimedes was serving the King Hiero II of Syracuse by solving mathematical problems and by developing interesting innovations for the king and his army.

Archimedes is known as the Father of Mathematics. Mathematics is one of the ancient sciences developed in time immemorial. A major topic of discussion regarding this particular field of science is about who is the father of mathematics.

The triangle was known in China in the early 11th century by the mathematician Jia Xian (1010–1070).

It was developed and mentored by two engineers of Indian Railways PC, Bihari and Swami Das, in association with Principal Dr. Kamran of CMS Lucknow India.

MUMBAI: Here's proof that Indians have a flair for mathematics. Indians scored higher than the global average in GMAT's quantitative section that tests math skills in 2010. But Chinese students have the highest average in quantitative scores, and India is far behind, at seventh position.

Indian mathematics emerged in the Indian subcontinent from 1200 BCE until the end of the 18th century. In the classical period of Indian mathematics (400 CE to 1200 CE), important contributions were made by scholars like Aryabhata, Brahmagupta, Bhaskara II, and Varāhamihira.

Leonhard Euler, a Swiss mathematician that introduced various modern terminology and mathematical notation, is called the King of mathematics. He was born in 1707 in Basel, Switzerland, and at the age of thirteen, he joined the University of Basel, where he became a Master of Philosophy.

Born April 30th, 1777, in Brunswick (Germany), Karl Friedrich Gauss was perhaps one of the most influential mathematical minds in history. Sometimes called the “Prince of Mathematics”, he was noticed for his mathematical thinking at a very young age.

The Egyptians invented the first ciphered numeral system, and the Greeks followed by mapping their counting numbers onto Ionian and Doric alphabets.

infinity, the concept of something that is unlimited, endless, without bound. The common symbol for infinity, ∞, was invented by the English mathematician John Wallis in 1655.

Horace Mann invented school and what is today the United States' modern school system. Horace was born in 1796 in Massachusetts and became the Secretary of Education in Massachusettes where he championed an organized and set curriculum of core knowledge for each student.

Archimedes' method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than the circumference of the circle) and the perimeter of a polygon circumscribed outside a circle (which is greater than the circumference).

The symbol π was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by Swiss mathematician Leonhard Euler.

India, the world's largest democracy, ranks No. 25 overall. It took top spots in Movers, a measure of economic potential, and in Heritage. These countries, which range from Austria to South Korea, performed the best overall in the 2017 Best Countries rankings.
