Another physics experiment for today’s Top 200 Photo

photo #90 is:

Another attempt at the physics stroboscopic shots. This time the pen fell too quickly so a lot of the images are in the bounce at the bottom.

This one goes out to all the physics geeks out there.  (Applied Engineering Physics counts too, Jing Qing)

Some pessimists decry that even electric cars have pollution created at the power plant thus what’s the point - let’s just have our current gas guzzlers. What they forget are their thermodynamics lessons in college. It’s no secret that we have yet to find an efficient way to convert fuel into useful energy. Of that $3 gallon of gas, only around $1 is used to move your car forward. The rest is blown out the tailpipe.

Man it feels good to be an engineer!
