Themed demonstrations, make-and-take activities and table-top games will celebrate pi, a number that is an important part of all things round. Visitors will learn more about pi and how it is used in everyday life.
The term π (Pi) refers to the ratio between a circle’s diameter and circumference. Simply stated, a circle’s circumference is π (approximately 3.14) times longer than its diameter. This concept holds true for circles of any size. Considered one of the more important mathematical concepts, π is important for many mathematical equations necessary in the areas of science and engineering. To honor the number, March 14 or 3/14 is known and celebrated as Pi Day.
