Entry Eighteen: "Close My Eyes and I'll Take a Riiiiiiiiiide . . ."

So this weekend I saw PEPPER. It was tight. Inside of the cramped, sweaty confines of the Pipeline Cafe, there were several physics concepts that could be observed. Sound waves from the amps were creating compressions and rarefactions in the air in order to produce the massive amount of sound necessary to rock out. There were too many collisions to count, most of them being inelastic collisions due to the tremendous amount of pushing and shoving in the crowd. And I am sure that there was something having to do with electricity and positive and negative charge taking place too.


Thank you Grace McLane, best Valentine's present ever.

Entry Seventeen: A Great Weekend for Raider Nation

The Iolani Boys Varsity Soccer Team are the State Champions. Chee! That was a good game. That was the first game I ever watched (on t.v. at midnight since I couldn't go the actual game), and I had no idea how sexy it can be.

Also, the Iolani Boys Varsity Swim Team are the State Champions. Chee! A sexy sport as well, due mostly to the attire.

Aside from that, I gleaned that there were certain physics concepts involved in the soccer game. Near the end of the game, Period One Physic's very own Reid Sakamoto ('09) was hit with a vicious shoulder tackle from some Millilani a-hole. This collision was not completely elastic, so momentum and kinetic energy were not conserved. If they were, then we would use the Conservation of Kinetic Energy and Conservation of Momentum equations. What else . . .

The average force of the collision is equal to change in momentum over change in time, or (mvi-mvf)/tf-ti. Although I don't know the numbers to calculate it, the force looked pretty big.

Needless to say, this did not halt our victory. Congratulations to the swimmers and soccer players. It is a good time to be a part of Raider Nation.


This reeks of jealousy.

Entry Sixteen: Doogs and Waves

I finally finished my Tanglewood audition tape! Yay! Now, I can sleep at night in peace.

This weekend, I went surfing with my brother and his friends in Kailua. The water itself isn't moving, but the energy that moves through it creates these waves which eventually break on shore due to friction against the sand on the bottom of the water. These waves are longitudinal. It was fun. This post isn't very funny.



Hey! It's Slater surfing!



Dogs are smart!



No they aren't! Hey now it's funny!

Entry Fifteen: Girl, We're Two Waves with the Same Frequency, so Let's Vibrate Through Some Matter Together

This weekend, I did basically nothing. I did not watch BJ Penn lose to GSP, but I was sad that he lost. I did practice my bass, an exercise that has a lot to do with waves. When I play the strings with my bow, I am actually rubbing them until they vibrate. This is not an obscene activity, but in fact, one that generates compressions and . . . . I forgot what the other thing was, we never really talked about it in class. Anyways, it generates these two things in the air, which is a longitudinal wave known as a sound wave. The different notes are formed by waves of different frequencies, and the greater the amplitude of the wave, the louder the note is. All of the notes have the same velocity, which is about 334 m/s, or the speeeeeeeed of sooooouuuund.

. . . just kidding, doc. rarefactions.



I play bass, as my grandfather watches on . . .
