We always enjoy [FloatHeadPhysics] explaining any math or physics topic. We don’t know if he’s acting or not, but he seems genuinely excited about every topic he covers, and it is infectious. He also has entertaining imaginary conversations with people like Feynman and Einstein. His recent video on tensors begins by showing the vector form of Ohm’s law, making it even more interesting. Check out the video below.
If you ever thought you could use fewer numbers for many tensor calculations, [FloatHeadPhysics] had the same idea. Luckily, imaginary Feynman explains why this isn’t right, and the answer shows the basic nature of why people use tensors.
The spoiler: vectors and even scalars are just a special case of tensors, so you use tensors all the time, you just don’t realize it. He works through other examples, including an orbital satellite and a hydroelectric dam.
We love videos that help us have aha moments about complex math or physics. It is easy to spew formulas, but there’s no substitute for having a “feeling” about how things work.
The last time we checked in with [FloatHeadPhysics], he convinced us we were already travelling at the speed of light. We’ve looked at a simple tensor explainer before, if you want a second approach.
Wasn’t youtube supposed to demonetize AI-generated content? Dave mentioned it on EEVblog few days ago.
This is clearly not AI generated content.
I concur with RP…. in other words… uh, what?
Did you post on the wrong article or something?
But to answer your question anyway, the new youtube guidelines that go into effect on july 15th don’t demonetize all “AI generated content” per se, but they expand on their existing monetization requirements for “original” and “authentic” content in a way that makes it pretty obvious youtube is intending to crack down on videos that are largely or completely AI generated.
Ah, math for that tensor tension headache.
Ah yes, but is there a lessor tensor tension (or just lessor tension) headache. I feel something coming on but now headache classification has just become so much more complicated. Ok well, Feyn man, that’s all I want to hear (for now)! š¤¦
Eight, sir; seven, sir;
Six, sir; five, sir;
Four, sir; three, sir;
Two, sir; one!
Tenser, said the Tensor.
Tenser, said the Tensor.
Tension, apprehension,
And dissension have begun.
Damn, you’ve got that running round my head so badly I nearly forgot I committed a murder…
But which direction were you facing when you committed it?
And don’t forget Z because we’re not standing on a perfectly planar planet surface.
You mentioned graphene which may have nearly zero conductivity in the z direction (perpendicular to the layers) but if one of the layers is shifted by the “magic angle”, then the combine sheets form a moire pattern of superconducting wells. Just in case you were disappointed in the lack of complexity, so far…
Tenser said the Tensor, tenser said the Tensor. Tension apprehension and dissension have begun!
