I know we're not supposed to use internet pics but I don't own a gun and didn't have a chance to go to a gun range or anything so please forgive me. Over the weekend, I watched an episode of Mythbusters in which they tested the textbook physics case that states that a bullet fired from a gun and a bullet dropped at the same time would hit the ground at the same time. Projectile motion tells us that the vertical component of motion is independent of horizontal motion. Thus, theoretically, both bullets would hit the ground at the same time. However, a documented testing of this example has never been done (according to the Mythbusters crew). After some small-scale tests, the Mythbusters tested this theory. It took a while to get their rig set up but when it was finally ready, the first attempt was perfect and proved successfully that physics mumbo jumbo actually applies in the real world. I thought this was a cool episode and yeah, it worked.

Symphony
Sorry there's no picture but my camera or computer was going nuts. Anywho, on Sunday, I went to the Honolulu Symphony's performance of The Story of Babar at the Blaisdell Concert Hall. While there, I just happened to notice some physics in the performance. I noted that all instruments create music using vibrations. Whether its a violin, a drum, or a tuba, it is the vibration of air that makes music. This vibration showed a couple of concepts like Newton's laws. The strings don't make any noise if nothing is done to them obviously. However, when they do begin to vibrate, it takes a while for the strings to stop. The cause of the vibration, the friction between the strings and the bow, and the vibration of the air, caused by energy being transferred from the strings to the air, all demonstrate a transition of energy and that every action has an equal and opposite reaction. Music is full of physics.
