Using computer models, the mathematician Edward Lorenz coined the term "butterfly effect" in 1972 to describe a phenomenon in chaos theory wherein the flapping of a butterfly's wings can trigger a cascade of tiny changes that lead to larger ones, like tornadoes. I do wonder what Lorenz would say about my jump.

Nothing. Repeat after me, "mathematical chaos describes mathematical models, not the real world". A mathematical simulation can display chaos. It means that simulation may not be useful to predict things, such as minor differences in initial conditions can trash weather predictions in certain cases. This does not mean that butterflys cause tornadoes.

Stop confusing nature with the model. Nature isn't chaotic. Your models may be. Generally they aren't.

If I roll my eyes while I yawn, will they fall out?

Dumb, but still the closest the Stranger's gotten to demonstrating scientific integrity on this matter.

As a bus driver, i object :)

I thought it was pretty funny.

Still, as it stands the Viaduct is probably one of safer roads in Seattle—until it isn't.

Nice thighs, Ansel.

You need to amplify the lateral sheer force, not the vertical stress. Pilings support against vertical but the damage risk is sheering forces.

Which means shaking back and forth like a monkey or ape.

So, other than annoying your fellow riders, what exactly was accomplished here?
