  I used to like and look up to SpaceX for the interesting stuff that they build,

  but nowadays i don’t care anymore. The company can fail for all i care. Musk spoiled it.

  The tipping point, for me personally, was when Musk seriously threatened to slash public spending in February this year. It shows a clear disrespect to the people, and frankly, a sociopathic attitude.

  Musk had everything, lots of money, lots of fame, lots of influence, but he threw it all away when he decided to threaten the wellbeing and lifelyhood of a lot of people just so that rich assholes can make an extra buck through tax cuts.

  it also matters because the complexity of websites is a burden to end-user devices. especially on weak smartphones, as i’m using rn, the power usage of heavy websites sucks a lot, as it considerably slows down the device overall.

  i guess Commonmark is the same thing as Markdown?

  this is why i love the fediverse (especially lemmy) so much: comments and posts are simple markdown.

  it comes quite close to the principle of distributing content in the way of markdown articles.

  Why are the pyramids in egypt?

  Because they were too big for the british museum.

  I like saying that society is a hot gas.

  It is a mass of small particles that barely interact with one another, heated up by the heat of anger and hate, floating in a large space aimlessly.

  My type of society would be a liquid, where particles are free to move but close to other particles.

  the thing is, when you build rockets, and they actually work, and put people on mars, you can reasonably demand that people who demand exponential growth actually go to mars, because earth is already full. this way, you can get rid of the billionaires.

• ⁨Comment⁩ on ⁨SpaceX's Starship blows up ahead of 10th test flight⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  this but unironically. send all the billionaires to mars!

• ⁨Comment⁩ on ⁨SpaceX's Starship blows up ahead of 10th test flight⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  but is it significant harm, compared to other things?

  i mean, every company harms the environment somewhat. streets pollute the environment through their presence. oil refineries leak huge amounts of methane into the air. factories often produce toxic chemicals as by-products.

  rather the opposite i’d say … ready for take-off.

  isn’t that Hitachi?

• ⁨Comment⁩ on ⁨Honda successfully launched and landed its own reusable rocket⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  I suspect it’s because the hydrogen molecules are bigger than a single helium atom, which doesn’t form molecules (since it’s a noble gas).

  So the hydrogen molecule only seeps through if it’s oriented right (since the hydrogen molecule is a stick-shaped molecule).

• ⁨Comment⁩ on ⁨Honda successfully launched and landed its own reusable rocket⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Yeah, if by “going over”, you mean accelerating in the horizontal direction, then you’re right.

  Just to illustrate this: Consider we want to put 1 kg of mass into orbit.

  First, we have to raise it by 100 km. That requires 1e6 J = 1 MJ of energy (formula is mgh).

  Then, we have to accelerate it sideways, to a speed of 8 km/s. The energy to do that is 32 MJ (formula is ½mv²).

• ⁨Comment⁩ on ⁨Honda successfully launched and landed its own reusable rocket⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  While what you said is true,

  i guess that most people’s motivation is rather the economic benefits. Think of it this way:

  The 1960s space race created jobs all across the US and inspired a generation of scientists.

  Mars settlement could do the same, but bigger. At least that’s the idea.

  I’m just glad that renewable energy will make us independent from middle eastern oil eventually. maybe then the bloodshed can end.

  ok but now, where does the word “Funke” (spark) come from?

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  yeah, true

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  There were electrochemical cells (invented in 1800) that provided a constant current for some time.

  Idk the details. Look up Galvanic cell, Volta cell.

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  ooh i always guessed the word “Funk” comes from function, i.e. the radio is a useful tool that has a function to whoever is using it.

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Two inventions:

  • Internet
  • Computers

  are independent of each other, but go together nicely.

  You could have an internet (sort of) without computers. Consider Teletypers, FM Radio broadcasts, or Telephone.

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  i would like to hear about it :)

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  which is about the frequency that the heart (german Herz) is beating with.

• ⁨Comment⁩ on ⁨Hertz, showing the difference between science and engineering⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  Funnily enough, Faraday seemingly also understood that the Electric Field only possesses a potential in the absence of changing magnetic fields. Because only in the absence of changing magnetic fields, the rotation of the Electric Field is zero, and only then it has a potential.

  Even if they had a complete model of all of physics, it still wouldn’t answer all questions, as a lot of important data is just random. Whether nature decided to go with D-molecule or L-molecule is essentially random.
