  The reason you need to slow down is because you’re starting on Earth, which means you’re moving fast enough parallel to the sun’s surface that for every foot you fall downwards toward the sun, the sun’s surface curves away by 1 foot. This results in the nearly circular orbit around the sun we exist in.

  If you start speeding up, the orbit becomes more elliptical, except your aphelion starts raising away from the sun because now you’re moving fast enough that you’ve moved more than 1 foot sideways in the time you’ve fell 1 foot downwards.

  Slowing down has the opposite effect. If you get your speed down to 0, you’ll fall straight down toward the sun as normal with gravity. But you don’t need to go all the way down to 0 velocity to enter the sun, you just need to slow down until your elliptical orbits brushes up against the sun’s surface.

  Understanding classical waves better is what helped me wrap my mind around the physical meaning of the uncertainty principle. It’s not just a technical limitation, and it’s not just because you need to interact with something to measure it. It’s just a property of waves. Since small enough particles exhibit the properties of waves, it only makes sense that we can’t know their location and momentum at the same time with arbitrary precision.

  The velocity of a wave is a function of its frequency and wavelength. But imagine a highly localized wave, essentially just a peak. What’s its frequency? Well, we find that it doesn’t have one frequency! If you decompose the wave, you find its mathematically a superposition of multiple sine or cosine functions with different frequencies and therefore velocities. So the more localized the wave is, i.e the more you know its position, the less and less you know about its frequency and therefore velocity.

  This stuff blew my mind when it was first explained to me.

  “Restrict it’s usage” lmao, no. The restrictions on alcohol are not comparable in any universe to the restrictions on illegal drugs that you can literally be put into prison for using.

  It literally does not matter that N2O is not perfectly harmless because nothing is, you absolute rube. There are OTC products massively more dangerous that will never be banned because the demographics that tend to use them aren’t widely maligned by the rich, old pieces of shit in power. That includes alcohol.

  Fuck you if you think your right to not have to smell weed or whatever in public makes it okay to throw people into prison.

  I don’t buy that they are banning it because of people getting high. That makes not one iota of sense while alcohol is still legal and much more harmful to your health.

  This really is just another instance of boomers trying to get one last fuck you in to their children and grandchildren before they walk out the door.

  It says they’ll make exceptions for legitimate uses, I assume that includes making whipped cream. It’ll probably just be much harder to legally get your hands on it unless you run a catering company or restaurant.

  CO2 would cause the cream to sour as a result of it’s acidity, and plain nitrogen isn’t soluble enough, so it makes sense that they’d include it as an exception.

  Fun and abundant drug with minimal long or short term health consequences: exists

  Terf Island: oi bruv, you got a loiscense for that squirty cream product? you can’t ave that mate, you might en up feelin good without gettin proper consent from the king.

  Breaking the law is actually cool and good. Ideally, I think people should break the law more often, not less often.
