      That was funny, but I think in just a teasing manner, like "two can play at this corrections game." I think they both know Veritasium was right on that; because, when one only shows one significant digit, rounding it is the best, accepted way. It's the power of ten that is important. I prefer scientific notation, "7.8 E-31".

      He could've found much more, but maybe he was trying to be nice. Derek, as he increasingly tends to do these days, muddled up a lot of details in his explanation. He gave the right answers, but for poorly communicated reasons. For example, the two copies of 100! that cancel each other out (one in the numerator and the other in the denominator) have very different meanings, which is a subtlety he should have better clarified. And worse, he did the calculation for a loop containing all of the objects, and then nonchalantly stated that the same works for any subset of the objects. Let alone mentioning that it works only for more than half of the total, it is poor communication even to take his edge case calculation and apply it to the interior cases without inspection.

      I don't think he was correct at all and the only way he was able to claim to have been right is to have framed the question as vauge as he could, and then retconned in the actual answer after he was called out for an incorrect video that wasn't even convincing. Knowing that there's a big difference between the amount of power the light gets instantly and after a second, the only way to salvage it is to make assumptions not presented in the original video. Assuming that the light bulb isn't dimmable, which is what most people think of when there's a light bulb in a problem, then he would have been totally wrong.

    I think reaction videos to other people's videos seem to come up more (on the suggested video list) as if they are more click-baity than usual! Maybe because we all like errors to be spotted... but are not so keen on having our own errors pointed out!
    Hopefully no one will expose someone else's errors in public in an embarrassing or humiliating way. It seems so many science/maths communicators on UA-cam all know each other so are all friends and sometimes friendly rivals!

    • @baksatibi
      @baksatibi Рік тому +24

      Regarding going metric, imperial unit countries could adopt the SI prefixes without completely giving up on the imperial units. Just pick one unit for each dimension (length, mass, volume, etc.) and start using the SI prefixes with it. For example you can have nanofeet, microfeet, millifeet, centifeet, decifeet, feet, decafeet, hectofeet, kilofeet, megafeet, etc. This would have the advantage that citizens don't have to suddenly get used to units they rarely (if ever) used in their lives, but gets rid of the non-decimal unit conversions which is probably the source of most errors when using imperial units. This also makes it easier to transition to the metric units because then only one conversion factor is needed per dimension.

    Actually I thought that the only interesting thing in his video was the statement that the warden can't beat this strategy merely by ensuring that his chosen permutation has a long cycle. Because, he says, the prisoners can simply modify the strategy by doctoring the permutation -- I think he says "add 5" or something. That's genuinely interesting and would merit amplification.

    • @AssemblyWizard
      @AssemblyWizard Рік тому +2

      Sure but what if my permutation is shifting all cards by one? (in box 1 there's card number 2, etc). This is a loop of length 100, and just by adding 5 (or any other offset except 99) the loop still exists.
      "This is my friend Derek, and what I think he meant to say is, all the prisoners need to remember a whole new permutation, and compose it with the given permutation"
      If they use some generic rule instead of another permutation, the malicious guard can construct the permutation to have big loops after the rule.
      If the guard doesn't know the offset they're planning to add then the 100-loop won't work, but probably there's a permutation which foils every addition.

    • @thelivetoad
      @thelivetoad Рік тому +3

      @@AssemblyWizard But it may not be a single loop. Think of a loop 1->2->3->4->1 of length 4. I am not sure what Derek meant by "shift by 5" but let's imagine a "shift by 1" here. Prisoner 1 goes to box one, opens it, sees 2, and shifts by 1: result 3. They then go to box 3, open it, sees 4, shifts by 1 (cyclically): result 1. So we get 1->3->1. But crucially this strategy never opens the liberating box 4. So I am confused by what he might have meant by this. You can easily doctor a permutation (in this case in effect squaring it) to make a permutation with shorter cycles (in this case 2 of length 2 rather than 1 of length 4) but you need a way to do this and lead each prisoner to the box with their number in it. You could instead "shift by 1" by first opening box 2, seeing 3; then opening box 4 and see 1. As long as the number of prisoners isn't prime this would always reduce the length. But there are other modifications possible. So there is lots of latitude for investigating this as a game.

    • @bennettpalmer1741
      @bennettpalmer1741 Рік тому +5

      @@thelivetoad The "add 1" is adding 1 to each box. The visual given was the first prisoner physically relabeling each box, then using the original strategy. So, the prisoner would first check box "1" (formerly known as box 100), then if that box contained a 6, he'd move on to box "6" (previously known as box 5), etc. This effectively randomizes the contents of each box, undoing the warden's sabotage.

    • @thelivetoad
      @thelivetoad Рік тому

      @@bennettpalmer1741 Well, any permutation of the labels will only result in the same cycle structure as before, so it cannot undo the warden's counterstrategy. Again, the main issue is "is there a cycle of length greater than 1/2 the number of prisoners". If yes then any relabeling maintains that reality. Some prisoner will be in that cycle. One of the ways of implementing the "shift by x" strategy (the second one I described above) would in effect traverse a positive power of the permutation. If prisoner y's number is in a cycle of length L then a power of that by a divisor D of L will reduce it to D cycles of lengths L/D. Of course you don't know the length of the cycle that contains your number and at any rate you have to make sure to implement such a strategy so that your number is in the cycle you end up traversing. (See my first example above.) The beauty of the original strategy was that by starting at the box labeled with your number you'd traverse a cycle guaranteed to contain the box with your number in it. Remember, the warden will not release you if you al find a box with a relabeled version of your numbers -- you have to find the box with your number in it as put there by the warden.
