But on Friday, March 14, the crowd was a little more robust than usual, for good reason. The date- 3/14- translates nicely into 3.14, also known as Pi, the mathematical constant.

PORTLAND, Ore. — Today is March 14, known as Pi Day for the famous mathematical constant — but it’s also Albert Einstein’s birthday. And while most people recognize Einstein for his famous ...

Pi Day is an annual celebration of the mathematical constant pi (π). Pi is the ratio of a circle’s circumference to its diameter, and it is approximately equal to 3.14159.

March 14 — a day you’re more likely than most others to eat — or throw — a pie and get a reduced price on your pizza. It’s all in celebration of pi (Greek letter π), the mathematical constant and ...

Willem de Sitter’s solutions to Einstein’s equations: His models describe universes where curvature is instead driven by a cosmological constant rather than matter. These ideas and concepts ...

Friday is Pi Day. Pi, the mathematical constant in math which represents the ratio between a circle’s circumference to its diameter, is commonly approximated to 3.14.

Understanding Euler’s Number (e) Euler’s number e is a mathematical constant that begins with 2.71828. Just like pi (π), it is non-terminating, which means it goes on and on.

The mathematical constant π has been calculated in numerous ways over the centuries. For instance, π is defined as the ratio of the circumference of a circle to its diameter.
