I don't know what to make of this week's vexer, so I'm just going to ask it. What substance, other than water, is LESS dense as a SOLID than as a liquid? As...
Hi Zz, ... Point well taken. I will still try the experiment on a few unsuspecting "data points" -- but you are probably correct on this issue...luckily I...
