It was a hot sunday afternoon, so I decided to go sit down on the couch and watch some tv with the fan on. My fan turns out to have an oscillating feature even though it's really old, so I punched in that button and sat down and relaxed. The fan blew air in a fairly wide arc, spreading the cool it throughout much of the room at a very quick pace. Soon I was relieved of the heat of the afternoon. I realized that this has a lot to do with the physics we are learning because it is related to oscillation and wave motion. The fan follows a certain pattern and always returns to the same spot in the same amount of time. If I were to graph the displacement vs time graph it would look like a cos graph with a medium amplitude.

thank you for voicing your concerns...unfortunately there were some complications which have been thought out and methodically refuted below:
(1) the 4 officers were CHOSEN, by us, haha, and at the beginning of the year we decided to make you SECOND, not CO, VP because we felt bad because of the 5 of us that would most likely compose of the officers, you were the only one without a title therefore we invented second VP for you so that you would be something...this would be due to the fact that you are no longer secretary because you didn't bring a writing utensil or paper to any of the meetings last year and consequently did not carry out any secretarial duties therefore we had to IMPEACH you and replaced you with our current secretary, em! therefore, second VP is NOT higher than treasurer for the previously stated reasons which conclude the fact that the position was created for the single one of the five of us who lakced an officer position... treasurer>second VP :)
(2)if you're such an awesome photographer, why did it take 3 shots to get a nice one?
(3)i hope doc! doesn't read this really long and sardonic comment
