Like.
Now I see my mistake. I was considering the change of level from the bottom of the submerged object. In such a case, objects with the... -
haruspex replied to the thread High School Tennis Balls in the Ocean.No, it does not make that assumption. I am defining H to be the height of the water above the base B of the ball. The top of the ball... -
haruspex replied to the thread High School Tennis Balls in the Ocean.Read post #15 carefully. The argument goes like this: With a ball floating inside its hexagonal prism, there are three regions of... -
haruspex replied to the thread High School Tennis Balls in the Ocean.It is not an approximation. Archimedes' Principle is exact and depends only on the volume, not details of the shape. -
haruspex replied to the thread Undergrad The countability paradox of computable numbers.Have we? How does the algorithm generate the list, to the required length, as needed? -
haruspex replied to the thread Graduate A rotating frame equation for the "carousel experiment".Except when the object is, instantaneously, at the rotation axis? -
haruspex replied to the thread High School Tennis Balls in the Ocean.Apologies - I misread your method. It’s fine, and it is the same as in post #1. -
haruspex replied to the thread Graduate A rotating frame equation for the "carousel experiment".https://en.wikipedia.org/wiki/Coriolis_force lays it all out very clearly. Correctly describing the motion in a rotating reference... -
haruspex replied to the thread High School Tennis Balls in the Ocean.Not so fast. Consider e.g. if instead they were almost the same density as the water, also hexagonal in section and 1m tall. (Btw, not... -
haruspex replied to the thread Graduate Probability puzzle.Which means it is not a solution to the problem. Each player can anticipate the other’s strategy. If player 2 calculates player 1's... -
haruspex replied to the thread Graduate Probability puzzle.Well, I have a result, but hard to be sure how accurate it is. R has probability of about 0.625 of winning. The strategy distributions... -
haruspex replied to the thread Graduate Probability puzzle.Working on it, but I don’t see an analytic way and I can’t get an accurate numerical result before the program exceeds its execution time. -
haruspex replied to the thread Graduate Probability puzzle.That does not define a stable solution. Exactly how long does L wait to decide R has failed to fire? If L waits for ##\Delta t## then... -
haruspex replied to the thread Graduate Probability puzzle.We have to make an assumption about realism. Can each duellist observe the other pulling the trigger and respond rapidly enough to... -
haruspex replied to the thread High School Geometry Puzzle: Cut The Figure to Make Two Identical Parts.The original text does not say "once". You added that in your instruction. But what does cutting once mean? It suggests a single...
