  The most famous case of a professional explosive maker blowing himself up must be Alfred Nobel’s own brother, Emil, who died on an accident on one of their nitroglycerin plants.

  OP need to train for languaging.

• ⁨Comment⁩ on ⁨Why don't electric car manufacurers put solar panels on the car roofs?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:

  Even on ideal conditions (close to the Equator, no clouds) like in Northeast Brazil, you only get 5.5 to 6.0 kWh/m^2 of Solar energy, which means the roof of a small car, with 1 m^2 of solar panels, would only generate that amount of electricity if they were 100% efficient. That’s just 10% of the battery capacity of a small EV, like a BYD Dolphin.

  My point is, even if solar panels doubled their efficiency, they would still only capture about half the energy of the Sun (currently, the best panels are at 24% efficiency), which means only about 2.5 to 3.0 kWh per day.

  It’s very easy to screw up distilation. If the temperture is not carefully controlled and you miss the points to discard the head and tails, you end up with lighter (like methanol) and heavier (like propanol or butanol) alcohols, all of them much more toxic than good old ethanol.

  Thanks for the explanation, I learned something new today.

  That’s because it detonated in orbit, so it interacted with Earth magnetic field. Far from the planet, I think there wouldn’t be an EMP, unless the targeted ship has it’s own magnetosphere. But I’m not a nuclear physicist, so take my opinion with a grain of salt.

• ⁨Comment⁩ on ⁨31-year-old teacher quit her job. Now she works at Costco—and boosted her income by 50%: ‘I've never been happier' (these are not feel good stories, this is sad)⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  Actually, 2/3rds. If she’s earning 50% more, that means the previous wage was 100 and now is 150. 100 / 150 is 0.6666… or 66.66%, 2/3rds.

  Sorry for the pedantism, but it’s the kind of math that needs to be correct to avoid misunderstandings.

  Still an awfully sad thing, tho. Teachers should be paid the same as doctors, IMHO.
