“Only Connect”On “Only Connect” last evening, the Mathematicians were playing agains the Wordsmiths. The Mathematicians won! “Only Connect” is a series of wordquiz game shows currently being shown on Mondays 20:30–21:00 on BBC Four. I was surprised the Mathematicians took ages to work out the value of . And there was a slight mistake on the show. is not but where is any integer. #2 20090721 21:15:12
Re: “Only Connect”The mathematicians were surprised at themselves too. Presumably the pressure was getting to them a bit. Why did the vector cross the road? It wanted to be normal. #3 20090722 05:10:34

I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20090722 05:53:30
Re: “Only Connect”Yes, that's how I know it as well. "Equal by definition" is different though. Why did the vector cross the road? It wanted to be normal. #5 20090722 06:08:41

Re: “Only Connect”
It all depends on which leaf you choose, but the standard one is to make the value pi.
I've seen this used by a few professors. I don't see anything wrong with it. Different people take symbols to mean different things. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #7 20090814 11:31:02
Re: “Only Connect”
During my maths degree I found that different lecturers, books and countries didn't have a standard for this (as http://en.wikipedia.org/wiki/Table_of_mathematical_symbols shows). #8 20090814 18:47:23
