    Knowledge is knowing that a few drops of gasoline contains all the calories you’d need in a day

    Wisdom is knowing that it isn’t a good idea to drink gas

      Pedantry is fact checking a comment, figuring out it would actually take around a cup (or 1/4 liter) of gasoline, then figuring out how to convert that to drops and pointing out it would actually take close to 4,700 drops, not just a few.

        Smart-assery is replying how it can still be consumed as just a single, very large drop.

          Smart-assery is replying that gasoline doesn’t have enough surface tension to form such a large drop.

            Lemmy-ing is recreating a typical Reddit thread but making sure every comment points out that they’re self-aware.

        Hmmm let’s see, you need roughly 2.39kcal or 10kJ of fuel a day.

        Gasoline has an energy density of 45 MJ/kg.

        https://energyeducation.ca/encyclopedia/Energy_density

        Sciencing those together means you need 0.00022 kg or 0.22g of gasoline a day

        Gasoline has a mass density of 0.7475 g/cm^3, more sciencing means you need 0.294 cm^3 of gasoline by volume.

        https://www.engineeringtoolbox.com/fuels-densities-specific-volumes-d_166.html (average across range and convert to g/cm^3)

        Here let’s pull a number out of our butts, let’s say a drop is a sphere with a diameter of 5mm, so the radius is 0.25cm. Volume is 4/3 pi r^3 which comes out to 0.065 cm^3/ drop.

        0.294/0.065 gives 4.5 drops.

        So you’d need 5 drops of gasoline to get your days worth of energy.

        Seems we’re off by a factor of a thousand. Most likely you doubled up on 1Calorie = 1000 calories. (Damnit food industry, what the hell?!?) 1kcal is already converted to the base calorie, as opposed to 1kCal.

      I also like the version: “knowledge is knowing that the tomato is a fruit, wisdom is knowing that you shouldn’t put it in a fruit salad”

        The full version is:

        Strength is being able to crush a tomato.
        Dexterity is being able to dodge a thrown tomato.
        Constitution is being able to eat a poisoned tomato and live.
        Intelligence is knowing a tomato is a fruit.
        Wisdom is knowing not to use a tomato in a fruit salad.
        Charisma is being able to sell someone on a tomato-based fruit salad.

        “Hey, isn’t salsa technically a tomato-based fruit salad?”

        “Found the bard!”
