content: I’m sure you recall Veritasium’s video about how electricity spreads in very long wires upon hitting a switch. And the huge debate it spawned. Do you think it’s over?Haha! You wish! Today AlphaPhoenix raised the bar:Watch electricity hit a fork in the road at half a billion frames per second (from Alpha Phoenix)

content: I think this one is better than Veritasium.It's so funny to see all his conclusions based upon a oscillioscope and twisted wires...!Think about twisted wire and how they works.If this continues we end up with free energi from the stars and the forever-going- machine.

content: AlphaPhoenix’s effort lacks scientific rigour, so this is not evidence in the strict sense. But it is as close as a relaxed, amateur experiment made for entertainment can get to it. Certainly at the level of proper preliminary research. And the effect is beautiful!Many might argue this is not a “real video”. But it is as real, as EHT’s pictures of Sagittarius A* or M87*, and the later M87* high resolution picture. Or as the much earlierwork by Ramesh et al. showing light propagation at trillion frames per second.

content: If I had an eternity to live on earth, rest assured I wouldn't even squander one single minute of it on this. Why does it matter? It seems these people have too much spare time, and little of worth to apply themselves to.

content: You have much less time on Earth than eternity. And you just spent it on writting a comment, which is going to be lost among trillions others and forgotten by everybody in a week. Now, THAT is a thing to ponder on!But, to at least not make it completely worthless, I will try responding: because there exists something called curiosity.

content: Quote from: golden_labels on December 09, 2023, 05:20:34 pmIt's sad how an entire industry grew that preys on people's curiosity with garbage videos like this. Veritasium is pretty much the YouTube version of TEDx: zero risk of valuable content, makes folks who aren't familiar with the subject think they just became masters of it in half an hour.

content: I have to disagree that this video is useless. We all could benefit from a better understanding of what happens in high speed circuits. I have spent many an hour working with a complicated piece of electronic equipment, and oscilloscope, and the need to have it do one thing while it is seemingly only capable of doing another. Understanding where those little squiggles in the oscilloscope trace actually come from is a tool to be working with that is almost invaluable beyond belief.Been there,Done that,There was no tee shirt for it!♪♪ You push the first valve down, ♪♪♪♪ The power goes round and round, ♪♪♪♪ Whoo, Ooo, ooO, Ohoo, Ho, Hooo, ♪♪♪♪ And it comes out here! ♪♪
