  • It only kinda works like this. If you have two slits, looking at it or not, you will see the top one. Now, the really weird thing is that if you fire a single photon at a time, you will still get the top one over time, suggesting that the single photon is somehow going through both slits and interfering with itself to do so. But the even weirder thing is, if you place a detector in one of the two slits to check which slit the photon is going through? You suddenly get the bottom picture.

    No, the difference is that if you double a kelvin number, you have quantifiably doubled the heat. If you double a Celsius or Fahrenheit number, you have not quantifiably doubled the heat… the number does not objectively count an amount of something.

    Think meters. A meter measures an exact length. Two meters is double one meter.

    Celsius doesn’t do that. Celsius is a scale between two amounts of heat.

    The equivalent for distance would be if we had a scale where 0 degrees distance was equal to 582.7762 meters, and 100 degrees distance was equal to 721.5323 meters. Each degree between 0 and a hundred is then a slice of that range. Maybe for the people who designed such a scale there’s useful reasons to do so, but you aren’t measuring the quantity or amount of something, you’re measuring a range.

    Kelvin measures molecular movement, just as hertz measures oscillations or cycles, or grams measure weight.
