  • i don’t think so, it’s like megatons to megawatts but stupider, instead of using up uranium from adversary they want to use up their own plutonium, while also having policies against spent fuel reprocessing (for alleged nonproliferation reasons, which is patently bullshit, power generation was straight up cheaper this way because new uranium is cheaper than reprocessing and use of mox. some other countries (at minimum ru, fr, in, pk, jp, cn, il) do reprocessing as a matter of national security/energy independence/hedge against future shortages of uranium). also this requires recertification of reactors for mox use, which won’t always work or else only part of uranium can be replaced, and if it’s for smr, then there’s gonna be a lot of plutonium in there, and it all starts with handing plutonium to motherfucking sam altman, for only a slight chance of any positive results

    i see it more as current administration ripping copper wiring from walls than anything else tbh




  • i don’t mean beta-oxidation, it’s just a series of separated normal reactions. i mean something like this: when first learning about ketones, you might learn about aldol condensation, which has enol as a nucleophile and another carbonyl as electrophile. at some other point you might learn about strecker reaction, which has iminium ion as electrophile and cyanide as nucleophile. but really, what you can do is mix and match, and you can pair enolizable ketone and iminium (mannich reaction) or carbonyl and cyanide (cyanohydrin formation) and then generalize, for example you don’t need strictly ketone for mannich, you can use any electron rich conjugated system like malonate or nitroalkane anion (henry reaction) or phenol or indole. to figure this out you need to study mechanisms. these last two are usually treated as variants of friedel-crafts reaction, but really categories like this are fake

    and to get that right, you need to know how these reactive intermediates look like, how reactive they are, what influences their stability which means that ochem starts with discussion of carbocations, carboanions, radicals, their shapes and orbitals involved, hyperconjugation, solvent effects and the like. and then first reactions taught are sn1/sn2, because these showcase these fundamentals nicely, and from there, it’s about introduction of more compound classes

    we only had synthons introduced during lecture at around 4th year, and only for ochem path, it’s not doing a lot at that point and imo would have much more impact right after ochem intro course

    you’re not missing anything, it’s an unhinged tradeoff that you do because you need to conserve copper for brass casings because nazis are in calais, there’s zero reason to do this today. apparently it’s still allowed in uk for some unthinkable reason but i haven’t heard of it anywhere else. yes, single fuse *per ring is used, rated at double what it would be in star/radial circuit

    you don’t even need a fault, sufficient asymmetry in ring geometry or load distribution already will cause this problem

    yeah that’s what separate fuses for separate branches of circuit are for, all in one central box because where else are these supposed to be. if your lamp is wired with 6A-rated wire then that branch should be fused with 6A fuse, which on its own is unhinged because usually much thicker wires are used anyway
