I was under the impression that solid helium was just out of the question at any pressure. Although my own search has revealed otherwise and your question points out similar.
Lets say 1atm, everything is solid at 0K except Helium which is still merrily a liquid.
My thoughts are currently...
I'm guessing this most likely has something some to do with Helium's superfluidity, but I'm still managing to draw a blank on what exactly stops it solidifying.
Any thoughts?
As the title suggests, I'm curious about the first experiments to find the speed of sound and who developed/performed them. Who was the first to really have a good crack at it? And who came up with the equations to how it varies under differing conditions?
We hear all the time about other...
I understand that this is a bit cheeky but I've found a problem on one of my mechanics problem sheets that is giving me a headache. As much as I could just ignore it I'd rather try and gain some more understanding of the vague world of rotation and orbit
Even at this early stage I'm...
