If you think of it, pi is actually strange. This unreasonable number shows up in the craziest locations. If you swing a mass backward and forward on a string, there’s a pi in there It pops up in the Heisenberg unpredictability principle, Einstein’s general relativity, and the interaction between two electric charges.
Naturally, the majority of people associate pi with circles. That’s reasonable, considering that one of the most fundamental meaning of pi is the ratio of the area to the size of a circle:
Now for the fundamental part. Tomorrow, as you may know, is Pi Day. Why tomorrow? Since it’s March 14– yes, 3/14– and 3.14 is the worth of pi to two decimals. Naturally, the real number continues to an unlimited variety of decimal locations: 3.14159265359 … and so on, permanently. That’s why it’s called irrational.
I should add that the United States is basically the only location that uses the middle-endian date format of month/day/year. If you choose the little-endian format of day/month/year, then today is 14/ 3– which is clearly not pi. (In that case I recommend July 22, since the fraction 7/22 is a relatively decent approximation for pi.)
Anyway, my traditional method of commemorating Pi Day is to find a brand-new way each year of determining a nume
