The US Navy Research Lab has determined that Hurricane Ivan, which devastated the Alabama and Florida Gulf Coasts last fall, produced waves in excess of 90-feet high when the hurricane was 75 miles out to sea. Remember when I was talking about the weight of water? One kilogram per liter? Okay, now take that liter of water and put it up 30 meters … and let it drop on your head. That one liter alone is going to knock you out or kill you … and those waves had tons and tons of water involved. [Metric tons, of course.]

Impressive.

[And yes, I know that kilograms are a measure of mass. Deal. It's tired, I'm late, and I doubt that I could do the math right now!]
