Found my new favorite YouTube Channel: Minute Physics. Fascinating, eh?

I've been sitting in Ohana Court for the past week or two looking up at the basketball hoops. The trusses didn't look like they were doing much. I was compelled to search for an answer. If you can sit through it, here's the explanation. (Spoiler: Internal trusses are under tension, they get pulled on. External trusses are under compression, they get squeezed. Each truss plays its part of disperse the load on the bridge.) Check out the last video for a quicker look at what's happening.

Here's another look at the physics that's more visual. Red=Compression Forces. Blue=Tension Forces.

If you want to skip to the really amazing part, start at 3:18.

My mother is a forerunner. Always one step ahead of the crowd. Ask her and she’ll tell you, it’s not an easy place to be. Challenge the status quo and things get ugly. Her latest battle: nutrition, wellness and alternative medicine has been no exception. Traditionally and unfortunately, I’ve sat among her naysayers. To be fair, the claims she made were pretty hard to swallow. “I’m being poisoned by my morning shower? Really, mom?” “The vial on your chest told the doctor what?” I figured it was her against the world. The whole nation couldn’t be ignorant? No way, sorry mom, you’re crazy. (Somebody tell me, is that "Read More" button hard to spot?)
