Explore the Matrix

I've been going through my google reader, catching up on whatever interesting blog entries I missed. One that I have been enjoying more and more is James F. McGrath's blog Exporing Our Matrix. It's sometimes academic yet readable, and he posts lots of sci-fi and science stuff, so what's not to like!
This entry from January is a good example of why I like it. His post on Santa and Religion was also very good.

Now for a random xkcd comic.

Cheers.
