##### Asked by: Anna Mitchell

Pythagorean Theorem. The Pythagorean theorem was **first known in ancient Babylon and Egypt (beginning about 1900 B.C.**). The relationship was shown on a 4000 year old Babylonian tablet now known as Plimpton 322. However, the relationship was not widely publicized until Pythagoras stated it explicitly.

## Who really invented the Pythagorean Theorem?

Pythagoras

Nevertheless, the theorem came to be credited to Pythagoras. It is also proposition number 47 from Book I of Euclid’s Elements. According to the Syrian historian Iamblichus (c. 250–330 ce), Pythagoras was introduced to mathematics by **Thales of Miletus and his pupil Anaximander**.

## Why was the Pythagorean theorem invented?

Hence, the sum of their area equals the area of the square built on the hypotenuse (the dashed one). So Pythagoras’ theorem holds for isosceles right triangles. The legend tells that, after proving this result, Pythagoras generalized his theorem, **to make it hold for right triangles whose sides are not equal**.

## Did Pythagoras actually discover the Pythagorean Theorem?

The Greek philosopher Pythagoras of Samos (lived c. 495 BC) is most famous today for having allegedly discovered the Pythagorean theorem, but, historically speaking, **he did not really discover this theorem** and it is even questionable whether he ever engaged in any kind of mathematics at all.

## In what year was Pythagoras born?

about 570 BCE

Pythagoras was born about **570 BCE** on the island of Samos. He died at Metapontium, in modern-day Italy, about 500 to 490 BCE.

## Did Pythagoras came to India?

What is even less well-known is that **Pythagoras had visited India**. There are documents from Greece dating back to before the start of the Christian era as well as just after the Christian era that describe his visit to the country.

## Who invented math?

**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.

## Who invented zero?

About 773 AD the mathematician **Mohammed ibn-Musa al-Khowarizmi** was the first to work on equations that were equal to zero (now known as algebra), though he called it ‘sifr’. By the ninth century the zero was part of the Arabic numeral system in a similar shape to the present day oval we now use.

## Who discovered pi?

Archimedes of Syracuse

The first calculation of π was done by **Archimedes of Syracuse** (287–212 BC), one of the greatest mathematicians of the ancient world.

## Is pi an infinite?

Pi is a number that relates a circle’s circumference to its diameter. Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That’s because **pi is what mathematicians call an “infinite decimal”** — after the decimal point, the digits go on forever and ever.

## Why is 3.14 called pi?

It was first called “pi” in 1706 by [the Welsh mathematician] William Jones, because **pi is the first letter in the Greek word perimitros, which means “perimeter.”**

## Who was born on Pi Day?

of Einstein

March 14 every year is celebrated as Pi Day to commemorate mathematical constant Pi. It is also the birthday of **Einstein**, one of the greatest physicists of all time. Einstein was born on Pi day, March 14, 1879.

## How old is Einstein today?

What would be the age of Albert Einstein if alive? Albert Einstein’s exact age would be **143 years 2 months 1 day** old if alive. Total 52,292 days.

## Who passed away on Pi Day?

On March 14, 2018, famed theoretical physicist and cosmologist **Stephen Hawking** died at his home in Cambridge, England, at the age of 76. Hawking was a celebrity both in the science community and in the public eye.

## Is today Einstein’s birthday?

Albert Einstein’s birthday is on **March 14** — 3/14 — which is celebrated as Pi Day. Did he ever make jokes about that?
