This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

Thermal image of a road that was just repaved (europe.pub)

I could feel the heat coming off it when I stood next to the repaved section. They didn't repave the parking area at the edge. Opened to traffic again, seems firm enough to drive on at 160⁰F.

Well, 0 is arbitrary in Celsius and especially Farenheit, so doubling that temperature isn't really doubling the heat.

Kelvin has its scale actually designed around how heat energy works. 160F is 344K. Double that and you've got 688K. Convert that back to stupid-units and you have 779°F

I think I did that right, at least. If nothing else it shows how whacky temperature math can be when doubling units gets wildly different results!

Hey, hey, that’s freedom-units to you.

That said, the difference in scales when it comes to doubling is something I never really considered. Very informative!
