    I've used both, though I'm not sure I can compare them directly, since it has been a year or more since I switched from Hacker's Keyboard. Unexpected Keyboard works well for me whe…

    If you want to be specific, specify the solid angle [0] captured, in your prefered units, e.g 4π steradians = 41253 square degrees = 1 spat. [0] https://en.wikipedia.org/wiki/Solid…

    I'm not sure if eddyg had a different idea, but I think the following sums it up: - base16 is a specification of how different UI elements map to colors [1], and also some tooling,…

    > the texture of the rice will come out quite wrong. Out of curiosity, in what sense can the texture be wrong? I never wash my rice, and I like the texture.

    Are you perhaps referring to the latest release (which was 1.4 years ago) rather than the latest commit on main (which was 41 days ago)?

    Comment #40242245

    Not to nitpick (I only stumbled upon this recently myself), but the mechanism driving a Crookes radiometer (which I presume is the type you're talking about) is not photon pressure…

    That was sort of my point. If we use a definition of "touching" that is relevant to the atomic scale, whatever that definition is, we can reasonably talk about what "touching" mean…

    Comment #40080656

    To be somewhat pedantic: "touching" is a word. The extent to which it is or is not an "exact science" depends on what is meant by "touching", and by "exact science". The definition…

    I disagree, as long as we're talking in ratios instead of absolute amounts. The difference between "a pinch of baking powder" vs "5 grams of baking powder" is about a factor of 20.…

    How about this: two objects are touching when the interaction forces between the objects are of similar magnitude to the interatomic forces within the objects. Very generally speak…

    disclaimer: I'm not an expert, but I've been watching some geology lectures focused on the pacific northwest [1] for fun recently. This is on the Jaun de Fuca Ridge, on the other e…

    Comment #39759747

    That is the common interpretation in the field, and in fact the phrases "strange metal" and "non-Fermi-liquid" are used somewhat interchangeably. I'd point out that there is anothe…

    Comment #39759597

    The understanding of strange metals, and more broadly, systems (i.e. materials) where strong (often quantum) interactions are important is one of the main general research areas of…

    Comment #39758577

    Minor but perhaps significant nitpick: the title of the article is "Quantum Weirdness in New Strange Metals Bends the Rules of Physics", and in this case "Strange Metal" is a techn…

    Comment #39573333

    4ad's comment has the right general idea. To explain in more detail: They compared pulsed light to continuous light with the same average power [1]. This means that the light inten…

    Comment #39573122

    It's not discussed in the linked article, but the paper it's based on argues against second harmonic generation and in favor of a two photon absorbtion process [1]. I'm not enough …

    Comment #39397230

    As a condensed matter physicist (working in the same field but not on altermagnetism specifically), I would say this is being much more picky about the language than most people in…

    I usually just use flour and water. Sometimes I add some salt. As far as I understand, this is very common, though perhaps less common for homemade styles of pasta.

    My 2 cents: > 4. The secret is to weigh the eggs and adjust everything using that measurement. This implies that only egg-based pasta can be made at home, which is not the case. > …

    To be fair to jaquesm, it looks like nanna's comment used to say '80 years ago' and was edited, so the correction was more significant. See comment by kitd.

    It has been a while since I read it, but I recall Cryptonomicon taking place mostly in south-east Asia. Are you thinking of Snow Crash? It's set on the west coast of the US (if I r…

    > i guess the "1D" short hand is well understood within the community. Yes, this refers to systems where only one dimension is important for the physics of the system.

    Comment #39137008

    In the jargon (at least in "low energy" physics and related fields), 'one-dimensional' often means that only one spatial dimension is relevant to the behavior of the system rather …
