https://www.youtube.com/watch?v=--rRyeh-viI idk if it counts as 'Educational' but the old Citroen hydropneumatic suspension systems were a wonder for their time, though from what I've read also over-complicated and a horror to keep maintained and working.

also have it serviced by someone who actually knows how it works rather than someone who just knows that "cranking adjustment bolt X will cover up problem Y"

There's a lot of poo poo like 2000s-era discovery channel where they stopped doing science and started doing EXTREME CREATURE COUNTDOWN poo poo or whatever, but there's also a lot of really good normal documentaries.

Dijkstracula posted:every now and again the algorithm serves me up something good for a change neat. the saddest part of nuclear physics is you can do like hydrogen or simple nuclei, but it's impossible to calculate/solve anything bigger. if you want to calculate stuff from bigger nuclei you just kind of have to make a whole lot of assumptions and it works pretty well, but not really.

Eeyo posted:neat. Yes. More precisely: the formulae become impossible to solve once more than one particle is involved (for the hydrogen atom we can focus on just the electron and it's solvable, but helium with 2 electrons isn't). At that point, scientists use a combination of smart assumptions and just bruteforcing an answer using powerful computers. The result of this ugly brute force solution is still orders of magnitude more precise than trying to solve it without quantum mechanics.

echinopsis posted:what makes it impossible? like truly impossible or practically impossible? we can only solve the relevant equations under very specific conditions, normally using some sort of tricky. the classic example of one you can solve is a particle in a 1d box - in the central region the potential energy is 0 (well, some finite value), infinite otherwise. because you know the probability of the particle being outside that central region, and in particular at the boundary, must be 0 (due to the PE being infinite), and that the resulting solution must be smooth*, you** can simplify the problem and enumerate the actual solutions. for the hydrogen atom they use clever tricks and the maths is harder (despite there being just a relatively simple PE field to consider), and it's just not possible in most other cases * even in this simple case you cheat a bit on this condition ** i could never really do this properly, it was all a bit hard and programming was easier.

yeah my understanding is that for approximating multi-electron equations via the canonical algorithm you essentially treat the wavefunction for each individual electron as independent, so the final equation ends up being a linear combination of those wave functions, but of course you lose being able to model things like van der waals forces because each electron's orbital can't be affected by any others in this model (I hacked on a bunch of computational chemistry stuff in undergrad and I never understood this stuff as well as I'd have liked but it was supremely cool to do Actual Science instead of fake computer "science" for a bit)
