Half as Hot

Careful, half of what, kelvin?

Probably want it between the winter temperature and the current summer temperature, but genies are traditionally fickle and pounce on any ambiguity

30°C is 303 Kelvin. Half of that is 151 Kelvin, which translates into a fairly mild -122°C!

Takes out hockey stick

Granted. Celsius now range from 0 to 50

Edit: ... or whatever unit you prefer. It's still the same

Reminds me of a time one of my friends was happy that it was going to warm up and said something like "it's going to be twice as warm tomorrow". It was going from maybe 20F to 40F or something.

That led to an interesting discussion.

This knowledge comes in handy with marketing BS around CPU coolers. If an aftermarket cooler gets a CPU to 35C when the stock cooler is at 70C, marketing will sometimes claim it cut temperatures in half.

I use this as an example for interval vs ratio; you can't halve Celsius because it's an interval scale where zero is arbitrary. Kelvin is ratio as it has an absolute zero-- you very much can halve it and doom near the entire planet next summer

Obviously we'd all die but I wonder how exactly. This would make a good question for Randall Munroe.

A good genie would instantly invent a metric of "number of degrees in excess of room temperature"

Is the temperature scale directly proportional to the heat energy? I think the amount of energy needed to raise water by 1 degree is the same no matter the starting temperature for example. Is 100°K double the heat energy of 50°K?

Could someone please explain?

Is that Kurt Angle?

Is it hotter down south than it is in the summer?
