  That doesn’t work anyway, since based on wheat variety, growing season, and grinding method, different flours have different information density.

    They have an international prototype sack of flour in an old missile silo in Kansas. Ultimately that’s what all the measurements are relative to

      Computational biochemists are working with a crack team of mathematicians as we speak to develop an alternative standard which does not need a reference mass

    I like to read bedtime stories to my wheat, so it learns more and has higher information density

    Sounds like the culinary world would benefit from having a measurement system that accounts for these factors.

  Still a more acceptable measurement than “1 cup”.

  source

  • VoterFrog@lemmy.world ⁨5⁩ ⁨weeks⁩ ago

    The whole point of cups is that you can buy an ingredient by the gallon and it’s very likely that you can double or halve the recipe to your heart’s content and eventually use up the entire package with no waste.

      Yeah, because no other metric can be divided by an other size of the same metric.

      That is why I always have 100ml over whenever I divide a liter by 250ml increments.

  Wouldn’t this make the units temperature-dependent?

  Landauer limit is one kTln2 per bit of information, so at 300K about 4 zeptojoule per bit.
  dividing by c² we get 46 micro-quectogram per bit, so 46 yoctogram per terabit. 369 yoctogram per terabyte.
  the Author wants half a septillion terabytes, 0.5•10²⁴ terabytes, half a yotta-terabyte.
  That makes 184 grams.

  Since I don’t know what on earth “a cup of flour” is, I can’t judge if the comic character proposes a reasonable conversion, but 0.2kg seems like a reasonable amount to use in cooking.

  For baking I would rather have my units temperature dependent than density dependent (I can compact my flour or work with water or nuts, all having different densities, but my room temperature will always be roughly 300).
  I condone einstein-landauer units.

    184 grams is a touch high for “a cup of flour”, but I’m not gonna check your math, and the comic probably wanted to use “close enough” round-ish numbers. The weight of a cup of flour is usually somewhere between 120g and 145g, going by the conversions used by major baking recipe publishers like King Arthur, Cooks Illustrated, Washington Post, New York Times, etc.

      I fear their apartment is at -50°C and this is a cry for help.

      At least I am relieved to know that even acclaimed authors native to the cup-measurement system don’t know what “a cup of flour is”.

      I’ll be off baking my pannenkoek with 150g of flour then.

      I figured it out. Typed the ln2 into my text and then forgot it in the calculator.
      Great, I’ma redo alll my numbers then rq

      Mass, not weight! Only because we’re being technical already.

  The real problem is measuring flour by volume instead of mass.

  source

  • Lucien@mander.xyz ⁨1⁩ ⁨month⁩ ago

    Solve both by measuring with moles

      are other burrowing animals also ok?

      Except that moles would only work for counting granules of ground flour, as there is no “flour” molecule. Also, you’d need to have a very accurate measurement of the average mass of a single granule (or you’d need a packing efficiency coefficient and an average granule radius, otherwise you’d have to literally count them. Also, a mole of flour granules would be INSANELY large. 6.02*10^23 of anything larger than a macromolecule is no joke. At this point, since you’d have to weigh it or measure its volume anyway (unless you feel like counting microscopic flour particles for the next few trillion years), you might as well just use grams.

  • cholesterol@lemmy.world ⁨5⁩ ⁨weeks⁩ ago

    The idea is that information must have a physical representation. But I don’t know how that would lead to a standardized mass of a byte.

    • vithigar@lemmy.ca ⁨5⁩ ⁨weeks⁩ ago

      No, you missed the point. See @milicent_bystandr@lemm.ee’s comment and link to Landauer’s Principle, the namesake of which is literally named in the title of the comic.

      TL;DR: Storing information requires a change in entropy. A change in entropy requires a change in energy. There must be a minimum non-zero amount of energy required for a given quantity of information. Energy is mass due to mass-energy equivalence. ∴ information has mass.

  Metric appears to end at 10^30, but even then, I think the better way to phrase that number would be 5,000 quetta-bytes

  Tera = 10^12; Septillion = 10^21 Source

  • Redjard@lemmy.dbzer0.com ⁨5⁩ ⁨weeks⁩ ago

    *500 000 quettabytes
    *Sextillion = 10²¹ ( = Zetta)

    I’d recommend wikipedia here, your source seems to have taken 3 years to update their table and their image is still outdated.

    They likely didn’t use quetta because it was only added 3 years ago, and is still not widely known. Or maybe it sounded better.
