I was talking with my best chum Yoshi Tamori.
Yoshi is a mathematical genius. He likes to talk about iterations and infinities.
One of Yoshi's favorite topics is the Euler–Mascheroni constant. One is filled with a sense of wonder when you ponder its definition.
Both the harmonic series and the natural logarithm of N tends to infinity as N->inifinite. However, the difference between these two infinities is finite, namely
gamma = 0.57721 56649 01532 86060 65120 90082 40243 10421 59335 93992.
The two infinities are "relatives" separated exactly by this finite number.
