    I also heard a claim that such patterns can (marginally) discourage graffiti of the seats. And if branding is a thing you care about, they can reflect some parts of that. London S-Stock trains’ seats point to the lines where they run, and there have been Danish trains that straight up feature the old DSB logo in the seat pattern.











  • LPT: find a plausible excuse to leave gatherings in a way that seems outside your control. This gives you an exit without seeming impolite. Between my parents, if one starts asking about the dogs, that’s their cue to start leaving. If they leave because “they need to take care of the dogs,” the hosts won’t have to know whether that means “we’d have loved to stay here but unfortunately, duty calls” or “we’d rather be spending time with our dogs than you guys.”

    According to that article, someone tried reacting it with just about anything he could find in the lab, and if it weren’t for the fact that it’s documented in a published paper, one could never be convinced that those experiments are the work of anyone other than a completely deranged scientist. The author of this article claims to have run out of expletives before finishing the second page.

    Also stated in this article, and converted for your convenience, reacting FOOF with H2S will yield about 1.8 MJ/mol of excess thermal energy.

    Most chemists, when you say “fill a reactor vessel at 700 °C with 300 torr of oxygen” and they notice a tank of fluorine gas in the room, will interrupt you and say “no you won’t.”

    Not while I’m within a mile of this lab. Two miles if I’m downwind.
