There’s more to Pi than meets the eye
Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π ”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
YPG had its 3rd annual celebration of Pi with a generous showing of over 25 different kinds of pies from savory to sweet to pizza pies. While pi has a wide variety of uses in the real world, a real life application problem that uses this problem would be a farmer that needs to know the amount of corn he would be able to put in his silo or when NASA uses it in its calculations for firing rockets into space.
As Yuma County’s premier scientific workplace, Pi is vital to many different facets of the proving ground’s mission, from weapons test planning and data reduction to weather forecasting. Here at YPG our electrical engineers use pi to solve problems for electrical applications, statisticians use pi to track population dynamics, aircraft designers use it to calculate areas of the skin of the aircraft, signal processing and spectrum analysis (finding out what frequencies are in the wave you are using) uses pi since the fundamental period of a sine wave is 2*pi, and finally navigation, such as the global positioning system (GPS).
YPG’s third annual Pi Day celebration took place on March 14, with lunchtime event-goers enjoying more than 20 different kinds of pie.
