You can kind of isolate the different vibrational modes and their corresponding energy transmission. "Phonons" are basically sound waves (the particle analogue), labeled in figure 2: https://www.nist.gov/system/files/documents/2019/07/12/dcs_2...
If you work a good 9-5 you've got several hours each day to tinker. Also, nothing in that video was 100k+. A nice watchmaker's lathe is ~10k. A full CNC enabled Bridgeport mill is 12k. That shop could be assembled with care for ~20k, or carelessly for ~50k. It's not nothing, but it's less than a boat. It's less than a country club membership. It's less than a few trips to Disney World.

Superfluid helium's maximum thermal conductivity is roughly 100x diamond's maximum!
They're trained to not maim or kill. More training won't fix it. More money and more resources won't fix that systemic rot.
40%, after all.
He has a long-running series where he works to make a new Antikythera mechanism using ancient (bronze age) technologies. He's a master machinist, so he has fabulous insight into workholding, precision, etc. https://www.youtube.com/show/VLPLZioPDnFPNsHnyxfygxA0to4RXv4...
His skeleton clock build is one of my favorite pieces of internet content ever, up there with Bartoz's gorgeous webpages: https://ciechanow.ski/cameras-and-lenses/
These guys will tell you their industry is more dangerous than nuclear power, and we regulate the living shit out of nuclear power. If you think models can't be regulated, look up the export controls on MCNP and tell me how that's different.
It's the same as a buttonhole camera used for spying. The differentiator (vs a phone or SLR or similar) is that its primary function is concealed.
Their contemporary equivalents seem to be interested in speedrunning a revolution that ends badly for everyone.
Direct verification of inverse square laws is hard! For electromagnetic interactions (ie Coulomb's law) you can use scattering. If you want to do a static experiment (Coulomb's Law the hard way or gravity) you probably need a torsion pendulum experiment. AFAIK the best in the world at that are at UW in the Eöt-Wash group: https://www.npl.washington.edu/eotwash/torsion-balances

There are minor variances locally, but you can make enough components common to benefit massively from economies of scale.
Indeed, we've largely missed the point of the "David and Goliath" story. David rolled up to a sword fight with a handgun.
I have a Waterman on my wall :)
It's great to use these tools to give you more time to be a human, but the ReadMe is for humans, and is dramatically improved by being set in your voice. The problem is that when your project description looks like the result of a solid twenty minute prompt session it woefully undersells the rest of the project.
It might be cool! I might bother to learn it! But I'm not going to care more than you about it.
The heading "The type system is gradual, and that is the whole design" is a dead giveaway.
Actually the whole "How young this is" section reads very LLM-y. Claude, I think? It's funny that LLMs have more distinctive authorial voices than so many people.
It's not a positive signal, because for the lifespan of that product I just bought, I have removed myself from the addressable market.
