Scales

This is because Fahrenheit is based on a brine scale and the human body. The scale is basically how cold does it have to be to freeze saltwater (zero Fahrenheit) to what temperature is the human body (100-ish Fahrenheit, although now we know that’s not exactly accurate). Fahrenheit was designed around humans.

Celsius and Kelvin are designed around the natural world.

Celsius is a scale based on water. Zero is when water freezes, 100 is when water boils.

Kelvin uses the same scale as Celsius (one degree, as a unit, is the same between the two), but defines zero as absolute zero, which is basically the temperature at which atoms literally stop doing that spinning thing. Nothing can exist below zero Kelvin. It’s the bottom of the scale.

So.
Fahrenheit: what temperatures affect humans
Celsius: what temperatures affect water
Kelvin: what temperatures affect atoms

Why didn’t my science teachers ever see fit to toss off this little fact?

Well that explains a lot, jesus.

A rare sight: “A partial annular eclipse shot at sunset from the front yard of my house in Amarillo, Texas. I think it’s safe to say that I’ll never see a sunset quite as unique as the one pictured here again.”

I WANT TO TOUCH IT

Can someone explain why the shoe didn’t melt or liquify or catch on fire?

It has a crusty skin on top because of the cool air. Once the skin breaks the heat comes through. Think of skin on porridge 👍

Thank you science side of tumblr

Physics.

Mythbusters fire a soccer ball at 50mph out of a cannon on a truck driving at 50mph in the opposite direction.

Kind of turned on right now tbh
