Wednesday marks the 30th anniversary of Pi Day's creation and celebration as a holiday, and it's also coincidentally physicist Albert Einstein's birthday.
March 14 is celebrated as Pi Day when the date lines up in the numbers of the famous constant.
Topeka native wins gold in Paralympics
Calgary's Alana Ramsay, 24, won women's bronze in 1:35:20 in the women's sitting super-G ski race for her first Paralympic medal. The United States, undefeated and unscored on in three games during Group B play, faces Italy at 7 a.m.

Google asked Cronut inventor Dominique Ansell to create the doodle for Pi Day, which was first recognised by physicist Larry Shaw. Ansel, in his signature chef style, honoured the mathematical constant by demonstrating the pi formula using his personal Salted Caramel Apple Pie recipe.
Pi represents the ratio between a circle's circumference (perimeter) to its diameter (distance from side to side passing through the center), and is a fundamental element of many mathematical fields, most significantly Geometry.
According to piday.org, Pi has been calculated to over one trillion digits beyond its decimal point. It's an important part of the foundation of mathematics, most importantly geometry, where pi is key to equations calculating the area of a circle, A = π r, and the volume of a cylinder, V = π rh.
But many observe the day with a different sort of circle, in the form of pie, or pizza. Therefore, it is an irrational number which is less than infinity. It was however, William Jones, a mathematician from Wales, who first gave the Greek letter its current mathematical definition.
