Zuse is probably the most under-appreciated thinker of the 20th century. Everybody's heard of Claude Shannon, von Neumann, Feynman, and all the rest of 'em, but Zuse's enormous contributions have received rather little attention. To summarize a couple of the highlights: In 1936 Germany, Konrad Zuse began developing the Z1, a mechanical calculating machine programmed via perforated 35mm film. By 1937, he had broadened…
> to surmise that our universe is computable by a deterministic computer program Please an expert chime in to complement, but I believe simulation in quantum mechanics is a quite interesting and not so simple topic. I believe the more correct thing to say is that quantum mechanics is approximable than simply computable. Don't forget, QM and current physical theories use real numbers, which are not digitally represent…
For things like light frequencies I believe we are not even sure if they are truly unquantized, so they might be discretely computable for all we know
Time is the tricky one. But if you get away from computing the whole universe and just try to compute the viewpoint of one observer that might be quite solvable
