I found it here on the microsoft research web page. Even though there are quiet a few mathematics, many of them are understandable enough. Even if you don’t, it doesn’t matter.

I hope this makes any of you who just have a passing glance at science to be truly interested. ^_^ (hat tip quantum pontiff) And if you are interested in the more advanced stuff, quantum electrodynamics, here is the link which I posted a long time ago.
