  • There’s plenty of insurers not in America…

    A nuclear reactor isn’t actually a very complicated machine, in a sense. Put enough nuclear fuel in one place and it gets hot. Then, drive a heat engine with it. Usually one based on steam, although closed-cycle gas turbines, sterling engines and airbreathing jet engines have all been experimented with.

    It’s just that you have to keep track of neutron moderation and cross sections, half lives of thousands of isotopes, thermal changes, non-constant demand and the possibility of point failures, all under the condition that you can’t let anything escape. That makes it complicated, but then again each individual part on that list can be learned from open-source materials.

    It’s even known what general kinds of reactors are on various military nuclear submarines. For example, the earlier Soviet designs used a liquid lead-bismuth cooled fast neutron design, which is why the Russians have so much polonium, while the modern designs use a pressurised water coolant.


  • I agree, it’s a fairly productive social science, but is there actual evidence that psychology has made an impact in organisation and management?

    There’s plenty of anecdotes and some hard numbers that suggest management is replete with bullshit artistry. For example, most office managers rely on in-seat time as their only measure of productivity.

    Mmm, I find it really handy to know that my memories are generated rather than recalled. Sometimes, I remember something that didn’t happen, and I know not to be weird and insistent about it. That hiding things from yourself is a really effective way to manage temptation is also not what I would have expected.

    I’d actually say that by social science standards psychology has an above average number of applications.


  • There’s at least as many parts in a modern reactor as in a dishwasher, but leaving that aside the modular building thing also failed to take off the n times it’s been tried, and for similar reasons. I fully believe there’s a speedup if you do the same project multiple times, although you’d find it would plateau after a while. There’s also a speedup associated with building something large and in place.

    The big savings happen when you reach a production run where you can build or configure specialised tooling and run it until after it’s earned itself back.
