Nerdy Elements

As a couple of engineers, I know that there will be incorporation of some nerdy science-y elements into our wedding. One good place to start is in the attire.

Here are some fun ties I found that the groom might get a kick out of (all from ties.com)What self-proclaimed nerd doesn't know the value of pi to 50 places?
Nuclear physics - classy!
Good old trigonometry and calculus - very important to engineers
But the best (and most subtle) might be this graph paper!
And one more example. I think this could be a really fun way to incorporate our nerdiness into the wedding (and make for fun pictures!)

What do you think?
