Computational Geometry and South Park

Okay, I won’t even pretend that I understand what the medial axis is, nor will I pretend that I know much about Computational Geometry. But if you’ve got a math presentation that involves South Park in one way or another I just have to check it out – and so do you.

First let me credit Ernie’s 3D Pancakes where I found out about Mesecina – computational geometry you can see. Check out the long demo talking about the medial axis and this crazy program called Mesecina which can even be downloaded, though so far you can only get the development version but apparently a release version with documentation will be available soon.

I might download it once the exams are over in case I have some time for crazy mathperiments.

Building your own Stonehenge replica

If you were ever wondering how the stones in Stonehenge got there and thought that it would’ve been too difficult for the people of the time to erect them without any of the tools that we have nowadays then I have a surprise for you:

Check out this video showing how Wally Wallington can move Stonehenge-sized pillars using only himself, gravity and his incredible ingenuity. He claims that Stonehenge and the pyramids could have easily been built using his techniques.
