What Causes Patterns in Water Droplets with Sound Waves?

[iDimension]

I've linked the exact time for your convenience. Sound waves or something is projected into a water droplet that causes it to create awesome looking patterns. What is this effect called? Thanks.

Edit: Unscientific link deleted by mentor.

Chladni figures or Chladni patterns. Also related to the Bessel functions if I remember correctly.

Yep. Chladni was an eighteenth century musician. Thomas Hooke invented the technique in the 17th century.

Chladni also seems to have been the first to suggest that meteorites were extraterrestrial in origin.

Sorry, but that narrator's woo-hoo about vibrational thought and vibrational emotion is nothing more than pseudo-scientific nonsense. "We are holding a vibratory pattern in the liquid crystal of our bodies." What the heck is he talking about?! He's just making stuff up as he goes.

[Edit: his off-the-cuff claim about Earth's "base pulse" of 7.8 cycles per second is probably referring to the Schumann resonance. It's true that that also involves standing waves. But beyond that, how it fits into any other of his extravagant word-salad is beyond me.]

Chladni patterns are real phenomenon and are well understood though. Here is a better video on them.

A lot of crackpottery surrounds Chladni figures. I think that this is the result of curious people who want to understand the world but can't deal with real science. So they settle for something that is simple and aesthetically pleasing. They are never going to use it for any practical purpose, so it doesn't really matter whether it's wrong.

I read some thing where the guy claimed that general relativity was fatally flawed. What was the flaw? That the guy couldn't understand it. So he made up something that he could understand. Whatever. Who knows? Maybe in the year 2321 we'll find out there was something to these intuitions.

That's pretty much all crackpottery in a nutshell.

I wasn't interested in the whole religious nonsense he was talking about with the pictures of jesus in the background. I simply wanted to know what the effect was called because when it's done with water it looks pretty cool

The Op's question has been answered and we don't discuss crackpottery, so the the thread is closed.
