Anyone know any problems that are "easy to understand but impossible to solve"? Like Goldbach's conjecture or Fermat's last theorem for instance.

    Haha well that's true, but I didn't mean it literally. I could google up unsolved problems, but I wanted to find some that other people had come across that maybe we could try to think about and try to solve together rather than alone.

    Haha I don't know what the best definition of a sonic boom is, I think it relates to going faster than the speed of sound and somehow creates a shockwave by displacing air or something fancy lol

    Got one: Question: Five pirates are parting ways after finding a treasure of 100 pieces of gold. The pirates decide to split it based on a vote. Each pirate, from oldest to youngest, gets to propose a plan on how to split the gold. If at least 50 percent of the other remaining pirates agree on the plan, that is how they will split the gold. If less than 50 percent of the pirates agree, the pirate who came up with the plan will be thrown overboard. Each pirate is smart, greedy, and wants to throw as many others overboard as possible without reducing the amount of gold they get. What plan can the first (oldest) pirate propose to live and get as much gold as possible?
