What’s pictured here is the Finite Element Method. Basically, the bridge is composed into little chunks, on which the physics solution is approximated by e.g. linear functions. Then one has to assemble and solve a system of equations (the matrix shown here) to determine the coefficients (i.e. slope) of those linear functions. Putting everything together gives a piecewise-linear approximation of the physics solution, and the smaller you make the chunks the better your solution gets. All of this is of course not done by hand, that’s what computers are for.

9·3 months agoThat’s very optimistic. History shows that once a regime is established, power is consolidated, the media is in line and protests are repressed, ousting the regime and rebuilding democracy can take a long time.
Russia had this level of obvious corruption and pillaging of state resources in the 90s, and where are they now?
The way I read it, the US donated twice as much as EU institutions, but EU countries donated as well, bringing the EU total above that of the US. Only counting EU institutions is like only counting donations made by the US federal government, but not those made by US states.

It really depends on what you’re getting in return. If your taxes paid for your healthcare and education, things would be different

Every car I’ve ever driven with such a feature only shuts off when in neutral and you let go of the clutch. For short stops, I just stay in first gear and keep the clutch pressed.
