    I Please Explain (actually explain) The Monty Hall Problem

    To put it another way, the contestant is presented with ##\{ \frac{1}{3},\frac{1}{3},\frac{1}{3} \}## but before a choice is made, the host adds information that makes it ##\{ \frac{1}{3},0,\frac{2}{3} \}## - the interesting bit is why is this a paradox that so many struggle with (myself...

    I Please Explain (actually explain) The Monty Hall Problem

    Agree with this If the host and the player have the same info at the same time, then the game cant depend on the host's knowledge

    I Please Explain (actually explain) The Monty Hall Problem

    This has been beat to death, but thought I would chime in that it actually does not matter whether the host knows what door the car is behind, if you pick door 1 and the host opens 2 or 3 without knowing where the goat is, there is a 1/3 chance that the host reveals the car and a 2/3 chance he...

    I am writing a SciFi story but I don't like Rayguns

    the BFG 9000 was great but there were never enough plasma cells to use it much. I do remember hacking the double barrel shotgun to give it the same rate of fire as the chain gun, which would shred anything

    I Midpoint(s) of the unbounded number line

    does midpoint = median? a standard normal distribution has a median of zero and its range is (−∞,+∞) but does that mean you have to define a convergent function on the line to define a midpoint?

    I When are Markov Matrices also Martingales?

    Risk neutral probabilities are martingales but <> 0.5 https://en.wikipedia.org/wiki/Risk-neutral_measure Can arbitrarily create a martingale with any binomial process

    Why are LLMs so bad at deriving physics formulas?

    Was at a conference today and the discussion was RAGs set up with physics laws as a constraint on the LLM, both to improve accuracy and reduce compute by trimming possible inferences to exclude physically impossible scenarios. The context was oil & gas, particularly infrastructure assets

    I am writing a SciFi story but I don't like Rayguns

    Why not a rail gun? If you can handwaive past the energy requirement, it’s the most powerful way to launch projectiles
