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... -
haruspex reacted to Andrew Mason's post in the thread Undergrad Textbook description of R##\ddot{\text o}##mer's light speed calculation with
Like.
Whether Earth is moving toward or away from Jupiter is almost immaterial in itself. The orbital period of Io is about 42.5 hours. In... -
haruspex replied to the thread Undergrad Textbook description of R##\ddot{\text o}##mer's light speed calculation.Bingo. As should have been obvious, it would not have been possible to time an individual transit since that is defined as the period Io... -
haruspex replied to the thread Undergrad How can light be a wave and particle at the same time?.You're right - I was looking at the first line of the body of the post, the bit to the right of the"TL;DR". I just assumed the title... -
haruspex replied to the thread Undergrad How can light be a wave and particle at the same time?.I have a suspicion that some respondents are reading the thread title as "How can light be a wave and particle at the same time" instead... -
haruspex replied to the thread Undergrad Textbook description of R##\ddot{\text o}##mer's light speed calculation.That’s reading too much into the way the diagram is drawn. The distances 1-2 and 3-4 will be about the same, but not exactly. Suppose... -
haruspex replied to the thread Undergrad Textbook description of R##\ddot{\text o}##mer's light speed calculation.The text is clarified somewhat by the caption on the figure: "When the Earth moves away from Jupiter during a transit." I.e. it’s not... -
haruspex replied to the thread Undergrad The natural numbers and logical consequences of them.Infinity is to do with things. How you can discuss things rigorously without developing a theory of sets eludes me. -
haruspex replied to the thread Newton's laws and inclined plane with friction.We are: The normal force between two bodies is, by definition, normal to the plane of contact of the bodies (if that is well defined)... -
haruspex replied to the thread High School A question about the rotation of points on a wheel."not moving at all" may be misleading. Its instantaneous velocity is zero, but it is accelerating upwards.
