There’s more to Pi than meets the eye

The Outpost - - Front Page - By Casey Garcia

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. 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.
