I haven't seen this before. Has anyone else?
The world was not as easy as I expected. Here are the steps I took to map it into the flattened icosahedron so I can print it out, cut it out, fold it and tape it to my shirt for Halloween. Start out with the world in lat-long. world2d =...
I am trying to get two people to sign up right now. They've got a good chance.
Sander, The likelihood of collision seems intuitive, but there are a bunch of conflicting intuitions going on here. The motions seem random, but space is really big, but time is really long. A collision ends a simulation, but it doesn't end the...
Following up on Charlie's post, there is a close relation to Kolmogorov randomness and other types of randomness, so any of the measures he mentions will satisfy Vitaliy's original question.
Marco and Bjoern, This is an incredible post. About the data relevant to the MH370 flight, do you know if the data from 2014 is available? Or is there a way for you to post some small amount of data like average currents for the Indian ocean? ...
One approach is to use a static visualization of the algorithm. Besides helping you debug what is happening, a static one might be preferable to what you are making in the first place. The simplest such is to use ArrayPlot on the evolution history...
Here is a simple example of a transcendental number that has no prime chunks (using a Liouville number) 4/9+Sum[2/(10^(n!)),{n,1, Infinity}] \[TildeEqual] .664446444444444444444446444444444444444444444444 but what is the measure of such...
It would be amazing if one could actually make this analogy computable, and then even more amazing to find a simple description of a large prime by starting out with a simple knot. This type of mathematics is perhaps more art than science,...
That site contains lots of material, not just courses. For instance, materials from the Wolfram Technology Conferences. Much of the content there is timeless, but the technology is dated. Nowadays there is the whole Wolfram Technology stack that...
