Pink Floyd and Physics

The album cover of Pink Floyd's album, The Dark Side of the Moon, is pictured below. This physics phenomenon occurs because of the differences in speeds of different color light through a medium. The colors have different frequencies which cause discrepancies in their indices of refraction. Violet, having the highest frequency, is refracted the most and moves slowest through the medium. Red, on the other hand, has the lowest frequency and moves quickest through the medium. The differences in speed cause differences in locations of the light as they exit the prism created a fantastic array of the rainbow. Thank you physics for giving Pink Floyd such an awesome album cover.

Backwash

I go surfing quite often. Whenever I surf at a break that is close to the beach backwash becomes a part of the session. The backwash is created by water flowing down the slope of the beach back into the water. A wave is created that moves out into the ocean. When it collides with another wave a large peak is created then the backwash and wave continue on in their original paths. It is clear that they do not bounce off each other because the wave going back out is the same size as the backwash and the wave approaching shore is the same size as the original wave. Therefore waves can go through eachother.

Blog like 9. Calculator Circuits

In pre-calculus we had to do a calculator project. This project reqires the student to create a program by entering a copious amount of graphs to form some sort of picture. My picture is the Cheshire Cat. It has taken many graphs and is not nearly finished but I took a break to write on some of the physics behind my calculator. Everyone of the hundereds of times I depressed a button on my calculator a circuit is completed allowing a flow of electricity to run through wiring inside the calculator. This triggers the memory of the calculator which holds the information of that single stroke untill it is needed again. Every time buttons are pushed circuits are completed so that electrons can flow through the wiring which has a voltage difference across it and current running through it. Wow physics is even crucial to the math that proves it.      

1st blog of Da Kine Second Semester.

When I was in Las Vegas this past summer I learned about static electricity. Everywhere in Las Vegas including the Hotel rooms is very dry. Since it is so dry static electricity builds up easily on many surfaces including our bodies. Jumping on the bedding with my socks on produced a static electricity charge through friction. After we finished jumping all over the bed I walked over to the sink and experienced static shock first hand. (pun intended) My whole hand felt a jolt as electrons flowed from my dry skin into the metal sink. Although it was surprising it was a total rush!! Static electricity is fun!!!

Blog something. LAST BLOG OF SEMESTER 1!!!

Surfing requires torque. I use torque all the time when I surf. In this picture I am doing some sort of a snap on the lip of the wave. To pull off this move I need to spin my board around almost 180 degrees. This is possible by doing work with my arms, torso, and legs to create a torque on my board and body. The resulting action is the completed snap. If I did not apply enough torque I would ot finish the turn and probably fall off my board like a kook. (which happens often) Thankfully physics helps me out everytime I grab my board to get some waves!

Blog 6 but should be 7 or 8

Surfing is a wonderful example of physics at work in my life. Beyond the obvious concept and physics of waves. Every turn I make while surfing is possible because of a centripetal force. When I start my turn, here a very basic, slow bottom turn, the rail of my surfboard angles into the water. This creates a normal force perpendicular to the point of contact between my board and the water. This normal force allows me to make wide or sharp turns even though the water has a low friction on my board because the component of the normal force pointing toward the center of my rotation. Thank God for physics and surf!

Physics blog 5 or somethin

The flow rider is pretty hard. But fun too I suppose. I would guess that a lot of physics goes into creating something like this. The creaters had to make the power of the water strong enough to fight gravity but not so strong as to shoot someone off into the air by the force of it. The water is flowing up te ramp thingy to keep me from sliding down. Since I can move on the wave-ish thing the force isn't totally in control. By gaining moment and moving my weight I am able to decide where I want to go on the wave. Ride creators must know a lot of physics to be able to create rides of all kinds that do such amazing stuff. PHYSICS IS FUN!
