Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Just looked at the Wikipedia page. What is the reason for so many fucking scales?

Different people deciding at different times that they need to measure temperature for something specific and then varying degrees of adoption.

Well Kelvin makes some math much easier. Formulas look pretty if you don't need to remove 213 a bunch of times.

Iirc it's 273.15 but yeah, less maths.

Is there any research on which xkcds are cited most often?

The purpose for this one is for scientists that normally use Fahrenheit. Those people don't really exist though

[–] [email protected] 3 points 1 year ago

they used to exist like 200 years ago

Title made me think centimeters.

Kelvin mostly seems to be used to measure unimaginably hot (like ovens, metal forges, stars) or unimaginably cold (e.g. planets beyond Mars) things, Fahrenheit still exists only because the US Congress was lazy (though as an American I do find it somewhat useful for comparing weather and Earth’s climate zones in finer detail than just -1 in winter and 28 in summer), and I’ve never heard of that last one.

Kelvin is useful in physics because it's always positive, reducing the amount of shenanigans.
