  • Fahrenheit has one advantage here: You’re used to it. If you’re used to Celsius, you know that 25° is warm and 5° is cold and don’t give a shit about it not being a 0-100 scale for that particular use case.

    The 0-100 thing is pretty much the only argument I’ve ever heard in favor of Fahrenheit btw. Again, if you’re used to one of them, that’s the one that will make the most sense.

    Being used to Celsius has the advantage of automatically being used to Kelvin. For example, if you ever want to calculate anything to do with the energy required to heat something to a certain temperature, you will have a way better time with Kelvin. Being used to and measuring in Celsius helps a lot here.

    But sure, I get that you’re used to Fahrenheit. It’s just that the whole world has decided to use Celsius. Honestly, for good reason.


  • Not an expert but iirc: Materials have a resonant frequency. If they are exposed to a sound of this frequency, the object will start to vibrate pretty strongly. If the sound is loud enough and hits the frequency well enough, it can cause such strong vibrations that the object breaks.

    This is how people are able to break wine glasses using their voice.

    However, I would think that different parts of a human body have different resonant frequencies so it probably wouldn’t work quite as well. Also, human tissue isn’t particularly resonant.
