Keep in mind that the society they are conforming to is much more open-minded, tolerant, and freethinking. It is possible that earlier "rebellious" generations have done some work in toppling barriers, and those positive effects a

My bullshit detectors are leaping off the charts. There are so many completely uncontrolled experiments described there, and the article just jumps to the conclusion that they demonstrate an effect. Add on top that the theory makes not a fl

My understanding is that Mersenne Twister is kind of a gold standard for non-cryptographic PRNGs. Linear congruential generators are known to be rather poor, and only ideal where speed is critical and the quality doesn't matter.

Wow, 1000 bounces is huge. 8 bounces is a reasonable setting for a high-performance 3D path tracer. I guess it's that much easier in 2D.

Maglev, huh. Does that imply the track has to have embedded coils / permanent magnets? If so, seems like that pretty much explodes the cost, no?

Cool. Many languages allow 0b11110000 style notation, though. If that's available, it's much preferable to hex when the bit arrangement matters. One should not ever force the reader to do the mental work of this quiz if it can be

If Blue Origin never takes this beyond a little pogo jump to the Karaman line, then SpaceX gets the last laugh. If they do scale this to orbit and succeed, then good for them! It's not disingenuous, and we all win. I don't see m

Brains are machines, and drugs damage them in such a way that the damage accelerates. If you think you are not driven by your own reward system, or that you are above it, you are laughably mistaken. By and large, you will do what your rewar

That is what is so unsettling about T-symmetry. What you describe is merely improbable , not impossible. With appropriate starting conditions, it is certain. Basically we'd require all the particles in the comet to bounce into each ot

Are you proposing a "hidden state" which is unobservable? Such a formulation is not consistent with quantum mechanics, as proven by Bell's theorem, unless you permit instantaneous influence from arbitrarily distant parts of t
