    Undergrad Carroll interviews Barandes on Indivisible Stochastic QM

    @Morbert you have played more with the math, what does t mean for a two level system, let's say a switch with two positions. What is the difference between the switch being in state up and it being in superposition of up plus down? In the first case it remains there forever while in the other...

    Undergrad Carroll interviews Barandes on Indivisible Stochastic QM

    How I am not following this discussion?! Edit: Oh I see, this is that 2025 podcast.

    Graduate Time evolution of a detected particle

    Well (assuming free particle) starting at ##|\psi(t=0)\rangle=|x_0\rangle## you need only to carry $$|\psi(t)\rangle=e^{-i\hat H t/\hbar}|x_0\rangle=\int_{-\infty}^{\infty} \mathrm dx\,\sqrt{\frac{m}{2\pi i\hbar t}}\exp\!\left(\frac{i m(x-x_0)^2}{2\hbar t}\right)|x\rangle$$ so it acquires a...

    Undergrad Heat radiation in vacuum

    Sure, consider it a "yes and" instead.

    Please give me examples of people who are famous for 2 different things

    Is philosophy and science two different fields? Because many did that.

    So AI is the ultimate arbiter here? You should decide what counts and check that AI is right about what it says.

    Undergrad Heat radiation in vacuum

    Yes but also outer space (in the sky) is at 3K, the windshield facing away from the house is cooling by emitting heat away. This is the principle of radiative cooling.

    Please give me examples of people who are famous for 2 different things

    Putting aside scientists that were also philosophers and scientists that were also politicians, I would consider: Thomas Young, not only greatly famous for proving that light is a wave (and also a bunch of things in mathematics, hearing, music and more) but also famous for being one of the main...

    Undergrad Heat radiation in vacuum

    1. yes 2. yes, note that there is no difference between the top lid and the other lids as in this problem gravity is mostly irrelevant 3. it depends on the temperature of the fruits, large temperature differences will result in more meaningful heat transfer.

    Other Technical books that have been read cover to cover

    I have a friend that during undergrad did all of the problems of Cohen-Tannoudji.

    It's been half a century - Why am I still warring with my printer?

    I strongly believe printer companies do not sell printers or software for printers, they sell ink. Printers are relatively cheap now, what they want is that you subscribe to these companies for ink cartridges which cost much more in the long run. You need to buy more cartridges even if some ink...

    Graduate How valid is the indivisible interpretation of quantum mechanics?

    More like Barandes interpretation does not want to define its properties in terms of usual entanglement terminology. I still don’t know if it super deterministic, hidden variables non local or something else (à la MWI). He wants to define it under Barandes made-up terms, by which nonlocality...

    Not Penrose

    The problem with Penrose consciousness argument is that it is full of holes, it is based on some quantum property of microtubules (the only part that can be falsified), which he mysteriously connects with Gödel incompleteness theorem (like what is the link there??? also he clearly assumes his...

    Undergrad "The wavefunction never collapses"

    Indeed that is known as the probability definition problem of MWI.
