Cool Science

Did you know you have lots of nerves at your fingertip? Of course - but if you ever want to be REALLY sure that they are there, just skin your thumb really good (think on the level of an ER visit) and then try to keep your mind off of it. Oh treacherous thumb, I love and hate thee.

OK, the point of the post was to take my mind off of the throbbing. I can always count on the wickedly awesome thinkgeek.com to brighten my day with genius products like this backpack: keep your things safe it will or this totally unbeleivable laser game that I wish I thought of.

Fermat famously bragged in the margins of one of his notebooks that he knew an elegant proof to the theorem which now bears his name, but didn't have the space to write it out. Well, I'm no Fermat because he was scary smart, but I've been sitting on an idea for a heat engine that generates power directly and which might fit in the palm of your hand. It would have decent efficiency I think and it's really simple and cool but I just don't have the space to describe it here.

You gotta love the brits.

For a little fun chemistry, check out what you can do with supersaturated solutions. I don't like calling it 'hot ice' because that dumbs it down too much, but cheers for a good video. I could probably show this in my class actually. Hmmmm.
