How would one use pi?
What is
1) electrical engineers used pi to solve problems for electrical applications
2) statisticians use pi to track population dynamics
3) medicine benefits from pi when studying the structure of the eye
4) biochemists see pi when trying to understand the structure/function of DNA
5) physicists looking into the behavior of fluid ripples see pi and use it in their calculations
6) clock designers use pi when designing pendulums for clocks
7) aircraft designers use it to calculate areas of the skin of the aircraft
8) 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.
9) Navigation, such as global positioning (GPS)
