@tensor_fact Couldn’t you say that about any topic that has been around 100 years?

@Eastlemon @Super70sSports Underrated 👏

@BrandonCallMeBT @Super70sSports Agreed. I loved watching him run but I really loved LJ. He had a 30 jump in 1982 in Indianapolis. They said he scratched. He didn’t. He got screwed. Like Beamon before him, Powell got lucky on one jump. Never really came close to that again

@chadhot @PaulMSherman You know me well!

How to estimate trailing zeros in factorials. Eg. 50! Divide 50/5=10. Divide the remainder by 5. 10/5=2. The trailing zeros are 10+2=12.

@jjfagan19 Yes

Babe Ruth hit 714 HRs. Hank Aaron broke the record on 4/8/74 with 715 HRs. 714 x 715 = 510,510. The factors are consecutive primes up to 2,3,5,7,11,13 and 17. The are no known larger consecutive numbers that produce consecutive prime factors. @jjfagan19

SNUB. Supernova unit in the B Band. This is an astronomical unit of measurement which represents the number of supernova per century per 10^10 solar luminosities in the B band. The SNUB for the Milky Way is 2 to 3.

For a VERY rough estimate of digits in ‘n’ factorial: n= 6 to 14 subtract 3 from n. n=15 to 18 subtract 2 from n. n= 20 to 23 subtract 1 from n.

Benford’s Law states that in a sets of real life data, the leading digit of any of the numbers will be ‘1’ about 39 % of the time while ‘9’ will appear about 5% of the time. This is used to find fraud in accounting cases.

A Planck length is 1.6 x 10^-35. The size of the observable universe is 8.8 x 10^26. Logarithmically a human is in the middle between the smallest known length and the largest observable thing.

Chess Pt 2. There are approximately 3000 named openings and variations. A GM will know the first 15 moves or so. So through 15 moves there are 9e6 games. If we assume a game is 40 moves and there are 3 reasonable moves each time, the number of games is 9e6 x 3^50 or 9e30

10^120. Shannon’s Number. Claude Shannon estimated that this was the number of chess games. He capped the game at 40 moves. There are actually over 11,000 possible moves which GH Hardy used to estimate the number of games to be 10^10^50.

1.618…Golden Ratio. It appears in nature & math. The approximate ratio between the Fibonacci numbers. It is the most irrational number. No fractional approximation gets you close. 22/7 is a close approximation of Pi. No such close approximation exists for the Golden Ratio.
