  • 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 really don’t have a clue, but calculating averages might yield results which don’t represent a directly applicable value. If some people lose tens of years due to dramatic complications, it could weigh up a lot for people who barely lose any life length.

    Again, I’m just guessing wildly, but anything which scares people away from smoking is good in my opinion.

    There are a variety of reasons, and of course there exists people who are in full control of their weight, but decide to not do anything about it. What I’m hinting at is that there are also a lot of people who suffer with deeper psycological issues. We don’t really tease depressed people with nick names and expect them to just snap out of it at any time. Hence I feel like we should generally treat heavier people with respect instead of assuming that it’s their active choice.

    Yep, the same way people can take full control of their depression, alcoholism or other psycological issues. It’s all about just rolling up those sleeves and deciding not to have the issues. So we can safely assume that all heavier people are a result of them actively choosing to become heavy, so we should always treat them as such.





  • I’ll have a go at this.

    “No stupid questions” is something I think is applicable to any attempt at gaining knowledge, insight or perspective. “How big helicopter would you need to hoist an ice cube to the sun to extinguish it?” Though absurd, there might be a disconnect of knowledge, and the question reveals other things which could be explained.

    To me, a stupid question would be some kind of rhetoric which doesn’t seek information, but instead attempts to redicule and push own standpoints or beliefs. “Have you gotten over that religious faith yet?” or “Do you realize how dumb your political views are?”. These are examples of ineffective and condescending and will likely just leave the other person with reinforced standpoints in addition to annoyance. I find that to be a stupid approach and thus a stupid question.

    I don’t really know, but it’s my gut feeling.
