Meet Archimedes of Syracuse: The Mathematician Who Discovered Pi and Designed War Machines
It’s the most wonderful time of the year—for mathematicians, anyway.
Pi Day is Thursday, March The relatively new holiday is a celebration of the mathematical calculation pi, or the infinite number representing the constant ratio of a circle’s circumference to its diameter. Pi is essential to engineering and modern construction.
Although many sought to find it, the calculation of pi, which is also expressed by the fraction 22/7, is commonly credited to Greek mathematician Archimedes of Syracuse more than 2, years ago.
According to , physicist Larry Shaw founded Pi Day day in , selecting March 14 because the numeric date represents the first three digits of pi (). It also happens to be Albert Einstein’s birthday.
The first Pi Day took place at the Exploratorium, a San Francisco–based science museum, and featured a circular parade and fruit pies. The latter has become a delicious tradition among academic and office settings. In , the U.S. House of Representatives passed a resolution recognizing March 14 as National Pi Day.
According to the Exploratorium, mathematicians began using π, the Greek letter pi, for the calculation’s symbol in the s, starting with William Jones in Leonha

What Did Archimedes Invent?
Archimedes was a mathematician and inventor from ancient Greece. Regarded as one of the greatest mathematicians in history, he’s the father of integral calculus and mathematical physics. There are many ideas and inventions that have been attributed to him. While there’s no exact date for his birth and death, he was born approximately between and B.C. and died sometime between or B.C. in Syracuse, Sicily.
The Archimedes Principle
Archimedes wrote in his treatise “On Floating Bodies” that an object submerged in fluid experiences a buoyant force equal to the weight of the fluid it displaces. The famous anecdote for how he came up with this was started when he was asked to determine if a crown was pure gold or contained some silver. While in the bathtub, he arrived at the principle of displacement by weight and ran through the streets naked shouting "Eureka (I have found it)!" A crown with silver would weigh less than one that was pure gold. Weighing the displaced water would allow calculation of the density of the crown, showing whether or not it was pure gold.
The Archimedes Screw
The Archimedes screw, or screw pump, is a machine that can raise water from a lower to a higher level. It is useful for irrigation systems, water syste
