Dear Ray Munroe,
Thank you for explaining to me lattice matters. I just quoted v. Neumann.
Descarte's hesitation got obvious to me from a Russian booklet by Cornelius Lanszos (Loevy) who quoted Einstein.
What about the number of dimensions, my argumentation is stolen from a book on physics of plasma the author of which listed many mutually excluding explanation of retrograde motion of cathode spots and argued like B. Russell on religions: At best one out of them can be correct. Hopefully, you do not feel hurt. Ren needs a high rating.
I do not know any reason to consider in theory the natural reference point for elapsed time hopping instead of sliding relative to the conventional scale. In practice, signal processing of auditory signals differs from the natural smooth one. It is restricted to a limited sample rate.
Concerning Heisenberg's uncertainty and what you called non-quantum ear, I would like to tell you that the smallest audible motion of membrane is in the order of a picometer, smaller than the diameter of the hydrogen atom, according to Schulman within the micro-world.
Replace E by omega and h by 1. The uncertainty relation would hold in signal processing too. Nonetheless cochlea and my spectrogram perform better, and I tried to explain why.
Do not worry about spin of point-like models. Recall bishop Berkeley. Models can be very useful even if they fail to model all aspects at a time. Look at the word trivial: three ways. No street is a line, no ramification of streets is a point. A point is still something ideal that does not have parts. Nonetheless I favor sinc(r) instead of 1/r.
To me there is no reason to separate between good physics, appropriate mathematics and good philosophy. The most common criterion is to avoid arbitrariness.
I dislike the word timetravel because it is often meant as an allegedly possible shift of time in reality. Here is again my distinction between past time as a measurable quantity that exclusively belongs to unchangeable reality and what has been abstracted from it and extrapolated: ordinary time. Of course we can shift, flip, stretch or otherwise manipulate any record or theoretical process.
Go in a cinema and travel back into the past. You cannot manage getting younger. I dislike technologies of fraud.
Future buildings do not yet exist. In so far they are not yet to be seen and not yet real. How stupid is a physics that ignores this peculiarity? The notion direction of time is better than direction in time but not sufficient. We have to accept causality, i.e. the fact that no influence comes from future.
Regards,
Eckard
