    What big gap are you referring to that you believe exists between the theory of any quantum computing platform (which is device physics) and the experiment? You seem to be conflati…

    If what determines the value of a language libraries (which makes no sense to me at all, but let's play your game), then it is one more argument against Python. You don't need FFI …

    Since you have a rosy picture of Python, I assume you're young. Python has been mostly a fringe/toy language for 2 decades, until around ~2010, when a Python fad started not too di…

    That statement is also incorrect. 1. "any representation of 3D rotations using only three values" That is not representation, that is parametrization. Euler-angle parametrization s…

    Also physicist here. I've worked on conventional superconductors, but never on unconventional ones. Last I heard, it was believed to be mediated by magnons (rather than phonons). W…

    You offer condolences, and you say you understand. Thank you, but what do you think you understand? Your analogy that somehow equates car accidents to nuclear disasters is not even…

    I'm a physicist. What education are you referring to? Downplaying the risks of nuclear power plants, which are real, is easy to do, as long as it is far from your home. Most people…

    To the parent and its sibling comments: There is no atomic or subatomic current that can explain ferromagnetism in any approximation. You read some Wikipedia pages and Feynman lect…

    Ferromagnetism has nothing to do with currents, it is due to aligned spins of partially filled shells. Below a certain temperature (Curie temperature of the material), exchange int…

    Raw performance per dollar (after including inflation adjustment) has stagnated in 40 Series. A similar thing happened in 20 Series. SUPER series has been a response to rival produ…

    What is "incorrect"? The full sentence that you conveniently chose to cut in the middle before quoting (apparently to fit into some pessimistic forecast about the significance of L…

    What of it? So does nvidia-vaapi-driver. They're third party projects, that's very different from "supported by the vendor", and doesn't change the fact that NVIDIA as a vendor off…

    You can make the same argument for VDPAU. AMD officially supports it, and there is an unofficial translation layer with limited capabilities for some Intel GPUs. Is VDPAU not a ven…
