Elliptic functions

Quarter period

In mathematics, the quarter periods K(m) and iK ′(m) are special functions that appear in the theory of elliptic functions. The quarter periods K and iK ′ are given by and When m is a real number, 0 < m < 1, then both K and K ′ are real numbers. By convention, K is called the real quarter period and iK ′ is called the imaginary quarter period. Any one of the numbers m, K, K ′, or K ′/K uniquely determines the others. These functions appear in the theory of Jacobian elliptic functions; they are called quarter periods because the elliptic functions and are periodic functions with periods and However, the function is also periodic with a smaller period (in terms of the absolute value) than , namely .

The Italian Calendar: Seasons, Months of the Year, and Days of the Week

We humans have built a lot of time-based social constructs for ourselves. Some are based on things we can observe, like the seasons, and one year being the cycle that repeates them. But things like months and days are completely arbitrary. Nevertheless, we have to learn them in order to co
