Thanks for ruining my day. Until now, it had never crossed my mind that I've been a sexagenarian for quite a while now. And don't anyone trot out that old joke about how it sounds like more fun than it is.

Apparently that video drew a lot of interest, but many people still had questions or had trouble understanding it. The presenter has uploaded a second video in order to clear everything up...

LibreCad has this print preview mode where there is a text box that accepts a print scale ratio. Also, the screen shows a representation of the page that you can drag aroud to set the offset, and thus select which part of the drawing will be on the page, and where on the page it will be. The...

It's hard, but a woodwind instrument can play multiple notes at the same time. This shouldn't be physically possible. In this video, we learn about acoustics and chaos theory to understand how this phenomenon works.

Exploring when and why a double pendulum is chotic or not.

This clip refers to an emission probability p. Would this be a probability density (probability per unit time)? The presenter doesn't emphasize this, but I would like to make sure whether that is the case. https://youtube.com/clip/UgkxxP5JQkuMJ62AVyDKdm6ixJFBVrT1-l7a?si=icaigJovcG5qg83l

In superdeterminism, it's already fixed what everyone is going to believe, right?

If the K number is pre-shared (and not embedded in the message), I suppose it would meet this criterion? And in that case, I assume a professional wouldn't find it hard to crack.. but what kind of analysis would yield the key? Hopefully the methods can be understood by someone who is not a...

Alice generates a random series of digits that define a key 0 < K < 1, using a physics based, nearly perfect random generator. She then calculates exp( Pi * K) / 4, or some such irrational number. She calculates as many decimal places as are required to encrypt the block of plain text. She...

Could it be something analogous to the "superliminal scissors" thing where the point of intersection moves faster than light? Say we have two plane waves moving in nearly opposite directions, but with say a 181 degree angle rather than 180. Then the nodes / antinodes might move faster than...

It's a while since I posted those questions, and it took me a minute to even understand Q1. Which could mean I haven't worded it very clearly. Edit: I think it would be clearer to just say "if a candidate function for the regulating function integrates to zero ... " Edit again: No, that isn't...

TIL how an aha moment yielded a key insight into the analogy between electrical and mechanical systems, leading to a secret device that contributed to McLaren's success in Formula-1 for several years.

The story of the J-Damper, a mysterious device at the heart of the biggest spy scandal in Formula 1 racing history.
