Mark Kelly is right about gun policy. His 85% statistic is bullshit

ScreenClip

I strongly support gun control.

DistributionOfPointsIdealGas

A molecule in a gas is being knocked into by lots of surrounding gas molecules. This is a very complex, almost random-seeming process. And yet we know that at higher temperatures the gas molecules simply must be moving faster on average. There must be a relationship between the temperature and the average energy. Moreover, we …
