If you read this blog, then you probably already know about xkcd, the web comic by the geektastic Randall Munroe. What you may not know is that Randall really is just that smart, with a keen interest in physics and math. He likes thinking about[...]

Physics marches to its own beat!

post from Physics Buzz on 12 July 2012 11:17:25 AM. © Physics Buzz

It started with the Cello. That was the fourth grade. I liked it, but it was a lot carrying and lugging that an 8 year old child should not have to endure. I then moved on the piano. It was cool to play. I just didn?t like only using my hands. I was pressing down on the foot pedals too hard, my instructor would advise me. After a few months I decided that I wanted to play the organ. That idea did not last long in my head. It was the contorting of the fingers again that was difficult for me to do, but I loved using my feet on the bass pedals below. Finally, I picked up a pair of drum sticks, and the story was written.
I was hooked and I practiced all of the time. The noise I would make was delightful at first with the smiles my family would have at an instrument that I loved to practice, loved to play, and would finally stick with (for the rest of my life?pun intended). After a few weeks, a practice pad was purchased to dampen the sound-smiles changed to hands over the ears and wishing that I would stop practicing. This is probably the track that most percussionists travel in their early years, the wonderful thing that is overlooked about being a percussionist is the amount of Physics involved.

From the rudiments like the 5-stroke, 9-stroke, double stroke roll, flam, ruff, paradiddle, ratamacue, and drag to the match or traditional grip, Physics encompasses a large part of the art of drumming. The lessons in Physics were there the whole time in my younger years. The amount of work done, the kinetic and potential energy concepts, the torque involved with the particular grips, and the amount of energy reflected from striking the stick on the drum head, the Physics was there. Take a look at the incorporation of Physics in drums. Enjoy!

Tribute to a Lost Era in American Travel

If ever a book on an icon of the American highway was decades overdue, this was it. Nobody had ever written a technical and social history of the GM Coach PD-4501, better known as the Scenicruiser, and commissioned by Greyhound at the Dallas-based bus system's very zenith. That, happily, is
