Pi Day is celebrated on March 14 (3.14) every year to properly recognize the constant
pi (π=~3.14159)---the ratio of the circumference of a circle to its diameter. At Wolfram, π plays an important part in every one of our products, allowing users to do everything from
getting the basic area of a circle to
rendering a π symbol filled with the digits of π. On Pi Day last year (aka the
Pi Day of the Century), the folks at SXSW got a very
special treat from us in the name of π. This year, we decided to bring the celebration to you by offering
exclusive discounts on Mathematica. Get 15% off Mathematica Home Edition and 25% or more off Mathematica Student Edition in select territories, including North and South America, Australia, and parts of Asia and Africa. Regardless of where you are, you can still celebrate with us by finding your
Pi Day.
