A great little art piece about how some very nice hourglasses are made.

Phil Plait again has found some good content from around the Internet. This time it’s a video from a YouTube user whom apparently does a good number of pieces on critical thinking. I think that I’m becoming a large fan of injecting science and education into popular culture.

Wow! There seem to be a good number of these kinds of videos popping up lately. This one is a breathtaking view of the known universe to scale. It’s constructed by the Hayden Planetarium. Absolutely amazingly done.

I’d love to see one of these with human understanding of the universe [...]

That’s a mouth full but it’s a pretty awesome little machine. A clock like this would be a pretty neat idea.

I must admit I’ve been a bit lax in posting one of the more interesting new pieces of Mathematics that has come around. I’ve enjoyed fractals for a long time and some of my first programs where of Sierpinski’s triangle, and the Mandelbrot. This has been saturating the interwebs, so I was reluctant [...]

With all this new work that I’ve been doing in Mathematics, I’ve started to enjoy various visualizations. Here is a really nice one showing the decline of the largest empires of old. I really like the way that the wars and independence of various countries.

I’ve a sweet spot for vehicle conversions. Keith, of Keith’s Electronics blog has bought himself a school but and is in the process of converting it. To what I’m not sure. However in his travels probably for inspiration he’s come across this interesting conversion from down under. I think I just [...]

Here is an interesting post from kottke.org, some high frame rate footage of bullets hitting various materials. I watched with the volume off, but it’s worth ten minutes time in my opinion. The most interesting part I thought was what appeared to be ballistics gel near the end.
Bullets are slow

I saw a soduko solver somewhere today, and this is the website that it was on. These are two pretty nifty robots, one that solves Rubik’s cubes and the other solves soduko. Looks like they’re both done with LEGO mindstorms, so given that small footprint these are pretty elegant solutions.

Phil Plait has up today a very well done piece of educational video about the nature of light. Apparently there is going to be a series of these, if they’re all this well done that should be great.
