"The mountains flowed before the Lord" in a song by prophetess Deborah recorded in the Bible (Judges 5:5)
It's actually used in rheology to describe if a materials acts more like a liquid or a solid. Even mountains acts like liquid at a big enough time scale :)
With such visually compelling frames, why not throw a popover that provides some context for those of us without physics degrees?
I really enjoy spending time at the shooting range (yeah, it is an Arizona thing :-), so the video gave me an interesting perspective.
