Video of a tornado in Dallas earlier today tossing tractor trailers around like toys
Earlier today, the Dallas-Fort Worth area got hit by some hellacious thunderstorms that came with several tornados, including this twister that picked up several tractor trailers weighing several tons each and just threw them around like they were tiny toys. Any DFW IHCers that got caught in this mess? Everyone okay?
I sat it out on the 24th floor of the Sheraton in downtown Dallas. Quite a show.
This really places things in perspective?

If Earth was the size of a basketball, all of its water would fit into a ping pong ball.
How much water is that? It’s roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey. Some 72 percent of Earth is covered in water, but 97 percent of that is salty ocean water and not suitable for drinking.
“There’s not a lot of water on Earth at all,” said David Gallo, an oceanographer at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts.
Life is purposeless. Don’t be shocked. The whole idea of purpose is wrong — it comes out of greed. Life is a sheer joy, a playfulness, a fun, a laughter, to no purpose at all. Life is its own end, it has no other end. The moment you understand it you have understood what meditation is all about. It is living your life joyously, playfully, totally, and with no purpose at the end, with no purpose in view, no purpose there at all. Just like small children playing on the sea beach, collecting seashells and coloured stones.
Delicious perspective goodness.
I found this scale of the universe on one of my favorite websites the other day and thought both the science and math departments would enjoy it. The link is to an interactive program that lets you zoom in and out in powers of ten and see the scale of the universe from the large (the visible universe) to the small (quantum foam). The program is a lot of fun and very interactive.
