    Gravity assist with one of the larger planets to make a very narrow orbit seems to be the most efficient way. But you need the planets to align correctly to have an efficient route.

    “I’ll launch you into the sun once there is an appropriate transfer window to Jupiter” just doesn’t have the same ring to it.

    The vessel would still have a lot of speed after escaping earth’s orbit, so the trajectory would become a large orbit around the sun. You still have to slow down by about ~30km/s (or ~100 000 km/h) to make that orbit intercept with the sun’s surface.

    In Ali Baba and the 40 Thieves, the number of thieves wasn’t really necessarily 40. The number was likely just chosen because 40 was an exaggerated number, much like when we’d say “I’ve told you a hundred million times”. So 40 as a shorthand for “a huge amount” seems fitting in celcius.

    Maybe if the fourth panel was removed, it would hold some humor. An expiration date on something so special as a licence go kill could give a soft chuckle. But since the fourth panel suggests that he is about to solve the issue somehow, it just makes it confusing. What is the funny part?


  • I hope I recall correctly: I was watching an episode of wan-show where they looked into a backpack returned from a miner after heavy wear, but little real damage. Live on the show they wanted to showcase the double bottom, so they cut into it (can’t recall if this was in the miners backpack or another one) and were surprized to realize there wasn’t a double bottom. Linus quickly assured, still live, that this would be handled for all customers.

    LMG did blame the manifactures of the backpack for removing a layer in a late stage design adjustment, but LMG have also alledegly taken a huge cost on assuring customers that they can receive a new backpack for free if the bottom fails for any reason.

    My memoery of this might be fuzzy, and the story I have heard comes fully from LMGs perspective, so take everything with a grain of salt.





  • But how do you apply this with Lorentz’ transformation (i.e. relativistic factors)? You cannot approach the speed of light without considering relativism. It is known that p = gamma * m * v where p is momentum, gamma is the gamma factor given by sqrt(1/(1 - (v^2/c^2))), m is mass and v is velocity. If you study the gamma factor, you’ll realize that it approaches infinite as v approaches c, the speed of light. Since we are actually dealing with light here, where v = c we are breaking the equation. Momentum cannot be defined for any mass which moves at the speed of light. It’s asymptotic at that speed.

    Also note that the same goes for E = mc^2. At relativistic speeds, also this equation needs to consider the gamma factor. So those classical equations break down for light.

    The answer is that photons don’t have mass, but they have energy. There is a good explanation a bit further up in this thread on how this is possible.




  • I never cared a lot. While I do notice the difference immediately, it never makes the experience differ in the long run. I have watched full length movies on the cover screen of my Samsung Zflip5 without feeling that I missed out on anything.

    I have a nintendo switch which I have used a lot. Even though I have a nice 55" TV and a decent soundbar, I very rarely connect the switch to the TV. I much rather use it in handheld mode so I can sit in any angle in the sofa. I guess I value comfort a lot higher than high fidelity.
