An insect that has the only mechanical gears ever found in nature (2013) (opens in new tab)

Thanks for posting that. It truly is mind blowing. It makes my head hurt just thinking about how life exists and it all starting with this insanity. In computing, there's this idea of a machine that could make itself, an idea Von Neumann toyed with. And yet, here is life, which figured it out billions (if not more) years ago. Makes you wonder just what in the hell is going on in this universe.

That video is seriously cool. Thanks again.

What you posted is so cool! And look at ATP synthase! wow. https://www.youtube.com/watch?v=kXpzp4RDGJI

These vids always make me want to eat healthier and exercise. Don’t want to let my little subcelular machines down after all this work:(

Youtube recommended a talk by the animator, which is fascinating:

Not an expert, but I feel like interlocking your hands does not count because the definition of a gear includes rotation, and transmission of motion. Interlocked hands don't rotate and they don't transmit motion.

Interlocking hands seems to me to be about grip strength. Sometimes it's easier to grip your other hand by interlocking than it is to grip the object you're lifting.

>What other things on the technology tree did we skip over and might we discover out in some insect, bird or fish?

Or beyond that, what fundamental physics principles have we somehow missed? Perhaps faster-than-light travel is actually really simple, and we somehow just haven't discovered it yet. Meanwhile, some much more primitive civilization elsewhere has, and is going to invade us soon with their FTL spaceships armed with... cannons equivalent to our Medieval weapons. They'll be in for a big surprise when we shoot back with guided missiles.

Ok, we've changed to that from https://canyouactually.com/first-mechanical-gear-ever-found-.... Thanks!
