You mentioned you believe different, more analog, hardware will be required in order to fully mimic biological (e.g. human) brain... -
PeroK replied to the thread A 1-Way Speed of Light.What you are really measuring, if anything, is whether a (rigid) object retains the same proper length when rotated in a gravitational...
-
Speed isn't a well defined measure in curved spacetime. So the answer is yes or no, depending on your coordinate choice.

PeroK reacted to renormalize's post in the thread Finding the nth roots of a complex number with Like.
Here's what Mathematica gives for the roots of the equation ##z^3=-2+2\,i##, expressed in both rectangular and polar form. You can use...

PeroK reacted to Dale's post in the thread A Is the constancy of c a postulate or a derivable theorem? with Like.
An alternative approach is to just write the most general affine transformation between inertial frames and determine the coefficients...

PeroK replied to the thread I Eddington’s margin of error.Probably. But, it gave the newspapers a great headline!
-
Unfortunately, in Eddington's day it was not common to report experimental errors. So you may need to look at more modern experiments...

PeroK reacted to PeterDonis's post in the thread A Physical properties of the vacuum in GR vs. QFT with Like.
I don't think there is a "canonical" process by which the community does this. Every physicist has their own opinion about it. Consider...

PeroK reacted to ersmith's post in the thread I Understanding the historical shift away from absolute simultaneity with Like.
It should perhaps be noted that while LET can reproduce all of the predictions of SR, it does not naturally extend to a theory of...

PeroK reacted to PeterDonis's post in the thread I Understanding the historical shift away from absolute simultaneity with
Informative.
There is no such thing. LET, as I've said, is SR, plus the claim that there's an unobservable absolute reference frame. It has to use... -
PeroK reacted to Herman Trivilino's post in the thread I Understanding the historical shift away from absolute simultaneity with Like.
Every theory has limits of validity. So it's always possible that a theory can be replaced with another that has less restrictive...
