### Blogging Mathematics

Writing about Equations in blogs from Blogbuilder news

My thanks to those who have recently given us the abiility to render mathematics in Warwick blogs.

I can't resist the temptation to try it out. Tradition has it that the phrase "Let no-one ignorant of geometry enter" was inscribed on the door to Plato's academy. For a more modern mathematical motto one might choose Euler's identity:

$e^{i\pi} + 1 = 0$

linking in a surprising manner five fundamental, apparently-unrelated mathematical constants: 0, 1, i, e, and $\pi$. Hence the in-joke "We are number $-e^{i\pi}$" sometimes seen on mathematics students' T-shirts.

1. I like that you have a category named Bagatelle. It made me smile.

I have to concur that e to the ipi plus 1=0 is a remarkable equation. A friend of mine once characterized this mathematical statement as "the five strangest numbers in the universe all linked together into one neat equation".
