| 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... |
| Thanks Rob, I see it now. I would call this more of a maze than an electric circuit. Technically an electric circuit has to be a circuit, and I think of circuit diagrams as having the funny symbols at the connections. I have seen several... |
| I think the Uud's were on Doctor Who (maybe spelled Ood). Ed, I find this unusual. Is there a reason for this sequence? Here is a version with a single graphic (so it is easier to annotate with arrows): texts = MapIndexed[Text, ... |
| Very cool. Udo's example (how can I l write a link that goes to his example?) reminds me of one of Stephen Wolfram's live experiments at the [2015 summer school][1] which might have used SubstitutionSystem, but might have also been even simpler. ... |
| More concretely, to add a boundary to the forest fire model one might just add cells which cannot burn and the boundary can be made of those types of cells. E.g., here adding state 3 BoundableForestFireRule[pGrowth_ /; 0 0, 2, Random[] |
