"I have a dream", "Tear down this wall", "I cannot tell a lie". Everyone knows these famous historical words. However, throughout history there have also been several numbers - this is the thread for those. RULES [unofficial - I have no moderation powers] -Numbers ONLY -Years, ages, quantities, distances etc all welcome -Have fun 1969 This was a great year. Woodstock. The moon landing. And guess what - the last two digits form one of the canonical funny numbers. Amazing. 200 Amount of Philistine foreskins presented to Saul by David in return for Saul's daughter as a wife. 0 Amazingly, this used to not even be a number at all, but now most Mathematicians think that it is. Incroyable. Depending on your precise definition, it was invented by the Egyptians or possibly the Indians.

1 The first year AD AND the last year BC. Yes, there was no 0AD OR 0BC - it just goes straight from 1 to 1.

Four Score and Seven, because the Gettysburg Address was a pretty good speech.

I like all the weird funny constants that show up in strange places. Pi, e, r , c all the good ones. G, g and the rest.

The square root of two, the length of the diagonal of a square with side length one. A clever proof shows that if the square root of two were actually the ratio of two integers, then we could produce an integer that is both even and odd. Impossible! Irrefutable proof that the Pythagorean school's philosophy, a perfect world measurable in integer ratios, was wrong. Legend has that a member of the school was drowned after showing this flaw to the outside world.

I like 419 because Jin Gongdi, age 33, succeeds his developmentally disabled brother Jin Andi as emperor of the Eastern Jin Dynasty. Andi is strangled by orders of the warlord Liu Yu. and 70 because 17th of Panemos (17th of Tammuz), about July 14) – Sacrifices cease in the temple.[5]

i Not a historical number, but I always liked the idea of an imaginary number. And I like how it was invented. "We can't go any further with this equation because there is no square root of minus one." "gently caress it, lets just make one up so we can move on and be in the pub by 4." Also 5318008, because I owned a calculator when I was 12. BrigadierSensible has a new favorite as of 04:02 on Mar 9, 2015 |

BrigadierSensible posted:i A very historical number! (Just not a number given to dates.) The number i is fundamental to our ability to solve problems in differential equations, number theory, physics, electrical engineering, and a lot more! You might also like the quaternion numbers, which go back to 1843. The Irish mathematician Hamilton had been sitting on the idea of extra square roots of -1 for a while, but couldn't figure out how their multiplication should work*. He finally figured it out while taking a walk with his wife, and was so excited he graffitied his equations onto a bridge. Quaternions are pretty useful for modelling Newtonian physics. *The trick is that ij = -ji. Quaternions are weird.
