so i was hungry yesterday when i got home and i noticed that we had cup noodles in the pantry. As i was heating my chicken flavored ramen in the microwave, i remembered how microwaves work. Microwave ovens send microwaves through the food, heating it with its kinetic energy. The high frequency waves are invisible to our eyes, but can be harmful with exposure.

i was at waikiki yesterday and i wanted to jump off the wall to cool off. However, the tide was a little low and the reef looked menacingly close to the surface of the water. there were wide rolling waves , and i jumped into a crest of a wave to make sure i didn't hit rock. By landing in the crest of a wave, i decreased my falling time thereby decreasing my speed, and increased the amount of water between me and the rocks which meant i had more time to slow down.

My little sister printed this piece of paper for one of her homework assignments. She's young and she thought it would be cool to print the assignment in different color texts (which it is). When i saw it come out of the printer i remembered what we talked about. The printer uses ink to 'color by subtraction' and make the different colors. It combines yellow, cyan, and magenta ink to form the black, uses the yellow ink as it is, combines yellow and magenta ink to form the red ink, and combines the yellow and cyan ink to form green. The black ink absorbs all light, the red ink absorbs everything but red light, the yellow absorbs blue light but reflects red and green light, and the green ink absorbs everything but green light.

On saturday i played a soccer game at kapiolani park. During one play, i was dribbling down the field toward the goal. There were two defenders between me and the goal, but i wasn't scared. I promptly lost the ball and the other team launched a counter attack. Apparently, a teammate of mine was wide open across the field and he would have easily scored had i played him the ball. The reason i couldn't hear him calling for the ball was because of the jammin hawaiians concert that was going on at the shell. It was so loud in there it drowned out anything we said to each other across the field. The sound waves emitted by the concert drowned out our speaking because of its massive amplitude. The concert sounds did not, however, block our voices. This is not possible, as waves pass through each other unaffected. It was just too loud.

I'm the brown guy. I went to the beach this weekend and there was a guy doing gainers into the water at china walls. He sprinted forward toward the edge of the wall, and jumped outward and forward while at the same time generating a backward torque to rotate his body backward, while moving forward into the water. It was pretty cool. He jumps outward and while hes in the air he pulls his knees to his chest to begin the backward rotation. Then he lands in the water and the water exerts a force on him to stop the downward motion. This force results in a change in momentum , constituting an impulse. Since it takes so much time for him to stop moving downward in the water, the force is proportionally small.

I use a wallet with a money clip on the outside. The money clip uses two magnets to hold the folded dollah bills together. The two magnets both have a north and a south pole, and both magnets exert a field. Due to the magnetic fields, the two magnets are attracted to one another. The people who made the wallet had to make sure that the two magnets aligned so that opposite poles come in contact, otherwise the money clip would not work. If the two south poles were facing each other or the two north poles, the two magnets would repel each other and serve no purpose. Sometimes, if i lean against something metal, my wallet is attracted to it and pulls my pants out to stick to the metal. The metal has to be iron, nickel, or cobalt in order for my wallet to do this to my pants, and it is really quite annoying.

This weekend i watched Without a Paddle on Comedy Central. Three men go on a treasure hunt adventure, searching for a lost parachuter's body with stolen money in the woods. Their search seems to be hopeless, as the men have ran all over the mountain being chased by a bear, marijuana farmers, and a corrupt sheriff. Suddenly, one of the men makes a realization. There is a huge iron ore deposit in the mountain, and this iron would throw off a compass. Because the iron is a magnetic metal, it makes sense that it would throw off a compass. However, will an iron ore deposit in the ground become magnetized? idk.

I just had a strange, strange dream. I was sitting in my yard, and this mean bald guy wouldn't let me leave until i found an example of physics (i dont know why). Anyway, i sat there and watched. Nothing moved in a parabolic arc, nothing fell and accelerated to the ground at 9.8 m/s squared, and there were no elastic collisions to be seen. I sat there in perfect stillness as did everything else in my dream. I began to grow nervous, was i gonna be stuck there in the yard forever with the bald guy? As it turns out, i ended up growing very old and dying in my yard. When i woke up a few minutes ago, i realized that Newton's first law definitely applied. There were no forces taking place, so all objects at rest (everything) remained at rest. Duh!

so for soccer we had states this weekend. there was a lot of physics involved. for example, blaine scored three times against mililani in the semifinals. blaine's first goal was a low rip into the goal. the velocity on the ball was so high that the goalie could not dive to the ground fast enough to block it. the goalie accelerated downward at 9.8 m/s squared, so the ball must have been traveling really really really fast. really. Blaine's second goal was a high rip to the right upper v. it was about a minute after mililani scored their first goal. yay! the net force applied to the ball must have been in the direction of the right upper v.

Today i watched the Super Bowl at my friend's house. When Eli Manning threw the 40-something yard pass to get a first down in the final minutes of the game, my friend Nick began jumping all over the room. When the Giants threw the touchdown pass to win the game, almost everyone in the room but me began to shout and jump all over the place, some in agony and some in triumph. As i watched these people leap up and down, i noticed that their body did not necessarily travel in parabolas. After giving it further thought, however, i realized that every person's center of mass must be traveling in parabolas. Although i did not stare at each person's belly button to see if i was right, nobody can escape the laws of physics.

Over Christmas break i went on a cruise around the islands with my family. Basically, the ship was a floating hotel complete with maybe 15 to 20 restaurants, three swimming pools, basketball courts, etc. As we were leaving Honolulu, i went out to the top deck to watch the ship leave. It took about half an hour just to turn the ship so it was pointing out of the harbor and even longer to get up to any kind of speed. Early the next morning, i got up to watch the ship dock in Kona. I realized that the captain had turned off the ship's propulsion well before we reached the harbor and we coasted for a long time very slowly. I realized that this is an example of momentum. Because the ship has such an enormous mass, it has a lot of inertia. This inertia makes it hard to get the ship moving and hard to stop once its moving. Because of this, it takes a lot of force to get the ship up to speed and a long time for friction to stop it.

Unfortunately i did not have a camera or my phone with me at the time, but hopefully my drawing is good enough. This weekend i went to zippy's to eat breakfast with my family and i noticed a big window decoration-thing. This thing was a picture of santa clause being pulled in his sled by his reindeer. The peculiar thing i noticed about the picture was that the reindeer were not hooked up to the sled, rather, santa was holding the reindeers' reins with one hand and waving with the other. My first thought was how strong santa must be to be able to hold onto the reindeer like that with one hand. I mean, the reindeer must be exerting a huge force on the reins to be able to pull santa and a sled full of toys. Due to Newton's second law of motion, this same force must be matched by santa's one hand in order for the picture to be plausible. I guess if santa can fly around the world in one night, he can probably exert large amounts of force with one hand.
