Hi @neiltyson. Mathematicians banished 1 from prime status so that every positive integer could be written uniquely as a product of primes.

Hi
@neiltyson. PS Speaking of primes, today triskaidekaphobia is supposed to reign supreme.Maybe we should banish 13 from primedom too? ;-) - 1 more reply

@neiltyson@JohnAllenPaulos That would exclude all other prime numbers since they would be a multiple of a prime.Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson@JohnAllenPaulos No. The rule is a number greater than 1 divisible by itself and 1. https://primes.utm.edu/notes/faq/one.html …Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson@JohnAllenPaulos What would that make Zero since it can't be divided at all? Is it the Alpha Prime? -
@ThePatMann No, zero has an infinite number of factors since zero divided by anything is zero - a whole number.

@neiltyson@JohnAllenPaulos Some would argue it's THE prime number. ;)Thanks. Twitter will use this to make your timeline better. UndoUndo

@neiltyson@CharlesMunn1@JohnAllenPaulos infinite primes, all but 2 are odd. So the chance a prime is odd= 1/infinity... So 2 doesn't exist -
@man_bites_dogma Geeeze, if so how can@memcculloch prove 2+2 = 4? & does that invalidate MiHsC? or F=MA?@neiltyson@JohnAllenPaulos
