    I think the point is that the bladder is above where the pee comes out so gravity could be pulling it out of the body. Aiming upwards wouldn’t change this relationship because the pee is outside the body at that point. By being upside down the bladder is now below where the pee comes out and gravity would be keeping it in. By being able to pee upside down, he demonstrates that gravity is not a necessary component.

    I think it can be demonstrated by aiming upwards with some extra pressure though. If gravity were the only thing pulling pee out, i wouldn’t be able to shoot over someone’s head for instance as the pee wouldn’t have enough kinetic energy. Thus gravity is not the only component.





  • If we know the values of ln(-1)¹⁰ and pi¹⁰ we hypothetically could calculate their divided result as -1 instead of using strict logic, but it is missing a few steps. Moreover logs of negative numbers just end up with an imaginary component anyway so there isn’t really any progress to be made on that front. Typing ln(-1)¹⁰ into my scientific calculator just yields i¹⁰pi¹⁰, (I’m guessing stored rather than calculated? Maybe calculated with built in Euler) so the result of division is just i¹⁰ anyway and we’re back where we started.

    I have seen 1 called a trivial factor, but I have never seen it excluded entirely from a factor list: perhaps it’s a cultural thing like how 0 is/isn’t a natural number depending on where you are from.

    On further research it seems like my earlier critique about requiring exactly two prime factors is a little off in any case, as it would exclude e.g. 4 (which only has one prime factor). It seems like semi primes must be a product of exactly two prime numbers so I think any definition based on number of factors is doomed to over- or under- define these semi primes as they could have either three or four factors.
