The dog is absolutely right. Even me, never really connected to knot theory, have heard about the Jones polynomial.dkotschessaa said:Found in Colin Adam's "The Knot Book," but found and copied/pasted from mathoverflow. (I added hyperlinks for the concepts needed to get the joke).

Can you explain? I don't get it.fresh_42 said:The shortest math joke: Be ##ε < 0##.
It's about conventions. As ##n## is an integer, ##z## a complex number, ##p## a prime, ##i,j,k## indices or ##A_{ji}## a transposed matrix so is ##ε## in calculus the byword of something arbitrary small, but positive. Uncounted definitions and proofs about convergence, differentiation or continuity start with an ##ε > 0##.Jonathan Scott said:Can you explain? I don't get it.
OK, I know all that but it still doesn't make sense to me when preceded by the word "Be".fresh_42 said:It's about conventions.

Yeah, probably, sorry! I had 'let' first and wasn't sure for it sounds a little like 'let it be'. In German it's 'be' (conditional).Jonathan Scott said:OK, I know all that but it still doesn't make sense to me when preceded by the word "Be".
Perhaps it's a language problem; I might expect a proof to start with: "Let ##ε > 0##" in which case "Let ##ε < 0##" might be considered a joke.
OK, that makes sense now, and Google finds that "Let epsilon be less than zero" or similar seems to be quite an old joke, probably predating Google (in that the oldest reference I could find appears to be from 1994).fresh_42 said:Yeah, probably, sorry!

I don't know details but a famous group of scientist once used this method to prove the geocentric model of our universe. I think they called themselves catholic church. They also have had a similar powerful PR department.dkotschessaa said:I have never heard of that particular group of scientists. I find their views interesting and I am very curious what methodologies they used to reach such a conclusion

You cannot know. There is no device installed to use some of that infinite power!DennisN said:
