    Graduate Does a Particle's Identity Have a Physical Cost?

    You are unambiguously proposing a new theory. We do not evaluate new theories. However, in addition to this being a new theory, your premise is incorrect: This is simply not true. Many particles decay. In doing so they cease being themselves and become something else. For the particles that...

    Graduate Is photon frequency intrinsic or observer-dependent?

    For a radio wave and a gamma ray propagating in the same spatial direction, the ##k^\mu## vectors are pointing in the same direction in spacetime.

    Undergrad Please Explain (actually explain) The Monty Hall Problem

    Oops, sorry I missed this earlier. This is a Bayesian updating approach. I used a uniform prior which is a conjugate prior. So after observing ##w## wins out of ##g## games for a given strategy ##\text{door}=d,\ \text{switch}=s## the posterior is a beta distribution ##p(d,s) \sim...

    Is A.I. more than the sum of its parts?

    Because if you do not disclose it then that is deceptive (plagairsim). Because if you do disclose it other people may not bother reading it. Because a lot of people don't want to communicate with AI. Because you might want to improve your own writing skills. Because it sounds generic to others...

    High School Why simplifying this function generates different outputs for same input?

    It is forbidden specifically at ##x=2##. Elsewhere it is not forbidden.

    Undergrad Single-photon double-slit with multiple apparatus?

    Personally, my view was more that it wasn’t a good way to test the history concept that you were interested in.

    Is A.I. more than the sum of its parts?

    That is a good question. It seems like a more natural business approach. Find small clearly defined problems whose solution is clear but difficult to program. Make an AI that does that and sell it. In that light a chatbot seems like a solution in search of a problem. Writing chat responses is...

    Is A.I. more than the sum of its parts?

    I wonder if it is possible to have a disagreement where people don’t exaggerate the argument they are addressing.

    Undergrad Single-photon double-slit with multiple apparatus?

    OK, so the test you are proposing is actually not a strong test of this. If you want to test for “apparatus history” you would want the maximum possible history effect, not the minimum. So you would want to use a single detector as long as possible. Then you would bin the collected counts into...

    Is A.I. more than the sum of its parts?

    Hallucination in this context is a technical term. AI does hallucinate in this technical sense. Nevertheless, that is the word that is used. Very often technical terms mean something different from the non-technical word that is used.

    Is A.I. more than the sum of its parts?

    That is not at all my experience. The vast majority of the AI generated physics posts of this nature are word salad. I believe AI can do decent summaries, we have trialed that among the mentors and my view of the summaries was positive. But not analysis or argument.

    Is A.I. more than the sum of its parts?

    Or because the outputs are a highly non-linear function of the inputs. I don’t think “more than the sum of its parts” is equivalent to “alive”.

    How does cloud memory work for a chat like WhatsApp?

    I do notice that as you scroll back the display can get slower. That must be related.
