Now that you mention it, aren't there superconductors that work at only liquid nitrogen temperatures?
The good ones work at liquid nitrogen temperatures. One of the previous times superconductors were the rage there were articles about a new one discovered, that only worked at 8°K or some such.
There are but they are ceramic which limits their applications because of poor mechanical properties.
They do say next research step is room temperature..
Sure it is. (Memory doesn’t run at room temperature. It runs at half the boiling point of water).
Memory runs at -68.5°C ?
You have water at -68.5 C? Most of us call that ice. So I am pretty sure you know what I mean and you’re flirting with the HN rules.
You can't halve the temperature of something by halving its measument in Celcius, because the celcius starts at some arbitary point above absolute zero.
50 degrees celcius is 86% as hot as the boiling point of water, not 50%.
You both did the math in kelvin then converted to C. You knew what you were doing.
