The Middle Square Method (Generating Random Sequences VIII)

Von Neumann proposed the middle square method of generating pseudo-random numbers in 1949, in a paper published a bit later. The method is simple: you take a seed, say 4 digits long, you square it, and extract the middle 4 digits, which become the next seed. 272 more words


Beyond Conway: Cellular Automata from All Walks of Life

There’s a time in every geek’s development when they learn of Conway’s Game of Life. This is usually followed by an afternoon spent on discovering that the standard rule set has been chosen because most of the others just don’t do interesting things, and that every idea you have has already been implemented. 1,262 more words


Is something like a re-discovery of the same thing by the same person possible?

Yes, we continue to remain very busy.

However, in spite of all that busy-ness, in whatever spare time I have ], I cannot help but “think” in a bit… 611 more words

Quick von Neumann stability analysis

von Neumann stability analysis is a great tool to assess the stabilty of discretizing schemes for PDEs. But too often, imho, the discussion is too convoluted. 854 more words


Monte Carlo Methods, where Math and Chance Meet

Can chance play a role in a mathematical calculation?

At first glance, it seems the answer is no. We usually think that a mathematical algorithm is deterministic, so that  1,058 more words
