    For the Ross-Littlewood paradox, another way to convince yourself that the box is empty is by contradiction- Assume after the process is completed, you pull a ping-pong ball from the box. Whatever the number on the ball is, you know you would have had to put the square of that number in the box already, so that ball shouldn't be in the box if the process has been done properly. As the number on the ball was arbitrary, any ball you pick shouldn't be in the box- hence no ball should be in the box.

I mean, to be fair, you need to wait until day 18 before you get even $1000(on a single day).

      I usually love things like this, and I accept that it’s algebraically possible to prove. I’m even okay with the logic. But an infinite number is essentially undefined; it’s impossible to assign it a finite value without mutating it somehow. We can use a finite number to represent it, as we would in programming, but again, we’re only doing that so our program doesn’t run forever.
      Infinite $1 bills = infinite $20 bills? Of course! An undefined amount of a defined value is equal to an undefined amount of any other value. The denomination is just some agreed-upon unit of measure and has nothing to do with the value.

      What happened to me is that I had to choose a singer for an opera and two ladies went to audition. So in the room we were four persons : these two ladies, the pianist and me (I'm a singer too). And it turned out that not only the two ladies were born on the exact same day and year (although not being related) but they also had the same birthday as me. So it was a 3 out of 4 with the same birthday and the same profession ! What are the odds...

    Same birthday problem. Take 2 people. Look at one of the people. The odds of not having a matching birthday is 364/365 (not counting leap years). For 3 people, the calculation is (364/365) x (363/365). For 4 people, (364/365) x (363/365) x (362/365), etc. When the chance of not having a matching birthday reaches .5, then the chance of having a matching birthday exceeds 50%.

  • @bokkenka

    The sheet or paper in the last segment loses half it's area with each folding... So, by the end it would be 1 / 2^42 it's original area. You are trading area for thickness. If 0.1 mm turns into ~440 Mm, then the length of the original sheet could be ~440 Mm and wind up at 0.1 mm long after all the folding. All you would need to do was stand it up on end rather than fold it.

    But numbers can lie. I'll explain: if 3 people get a hotel room, that is $25 a night. However, because $25 can not be divided evenly, each person pays $10 each, therefore paying $30. Now, because the room was overpaid, the manager tells the bellhop to take the extra $5 to the room. When the bellhop gets to the room and the guests can't divide the $5 evenly, they each take $1 back and tip the bellhop $2.
    Therefore, the three guests paid $9 each. Well, $9 * 3 = $27, plus the $2 tip equals $29, so where is the 30th dollar?

    • @ThatWriterKevin
      @ThatWriterKevin Před 3 měsíci +1

      First of all, they're incorrectly charged $30. They don't just voluntarily give ever money. But regardless, math isn't lying, YOU'RE lying. You are correct, they all paid $9 each: $25 to the hotel and $2 to the bellhop which equals $27. The other $3 are the three dollars they were given back by the bellhop.

They use this math to hide the money, use the same story but add a couple of zeros behind those numbers. The "books" will look correct on the bottom line with a cursory look and it is not until you dig into the numbers to find the truth. My point was to show that numbers can very easily lie to you, I am just demonstrating it using very simple math, to make it easy for the average person to understand.

    If this is yet another video saying infinite sum is -1/12...
    It's good to remind yourself that the probability of 50% for two people of 23 having the same birthday does not mean that if you have 23 people, there will be two with the same birthday. It means that if you enter a 23 people room, you can flip a coin to see if there's two people with the same birthday. And you can still flip a coin many times in a row without getting one side. And as far as I understand, you have to assume they are randomly spread, not that there's a pattern that affects where the birthdays are.
    Note that it was only 379 pages because they used the extremely dense notation that was "humanly incomprehensible" so they wouldn't have to write rows upon rows of text for each expression.
    With $1 and $20 it's also good to remember that there in fact is different size infinities that you can clearly distinguish as one infinity being larger than the other. Even though infinities technically can't be compared when they hit infinity. Like 1+2+3+... Vs 1*2*3*... One grows much much faster.
