Isaac Newton

Posted in school with tags , , , , , on February 13, 2008 by Jamie

Isaac Newton was born in the town of Wollsthorpe on the Eastern Coast of England in 1642. He went to school at Cambridge University in 1661. He was elected a Fellow of Trinity College in 1667, and Lucasian Professor of Mathematics in 1669. He was called the “father of science” and was very famous for creating his three laws of motion and gravity. He died in 1727. His first law is that  any object moving at a steady speed in a straight line will continue moving at a steady speed in a straight line. Under these conditions, the first law says that the velocity of an object will not change unless it is pushed or pulled upon. This law also means that a motionless object will remain motionless unless pushed or pulled upon. If there is more than one force on the object in question, the forces add up and become a net force. If there is a strong force pushing left and a weaker one pushing right, then the overall net force will be to the left. Newton’s second law states that an object will change velocity if  it is pushed or pulled. It first stated that if you do put force on an object, it will accelerate. It will then change velocity and will change velocity in the direction of the force. Second, the acceleration is directly proportional to the force. That means if you push the object three times as hard, the acceleration will be three times as much. Third, the acceleration is inversely proportional to the mass of the object. If you are putting the same amount of force on two objects, but one of the objects has three times the mass of the other, it will accelerate at one third the acceleration of the other. His third law states that for every action there is an equal and opposite reaction. that means if you push on a desk,  it will push back on you as hard as you are pushing on it. Also think of the flying motion of birds. If the bird is pushing air downwards the air must be pushing back up equally. The size of the force on the air is equal to the size of the force on the bird. This is a picture of Newton:

Mitt Romney Drops Out

Posted in school with tags , , on February 7, 2008 by Jamie

So I guess you heard the news that Romney dropped out. If you didn’t, then Romney dropped out. I am not exactly sure why, maybe i was because McCain was way ahead or something, or he didn’t want to commit to the campaigning, but he still dropped out. I personally didn’t like Romney (sorry to all you Romney fans) so I am kind of glad he did so. But all and all, he dropped out. This is the link to the New York Times website article:http://www.nytimes.com/2008/02/08/us/politics/08campaign.html?_r=1&scp=1&sq=romney%20exits&st=nyt&oref=slogin 

Energy Balance Equation

Posted in school on February 6, 2008 by Jamie

My question was question 3. The energy Balance Equation is used to calculate the average temperature of the Earth in Kelvins. First I solved it symbolically then with numbers.  S/4 (1-A)/εσ = εσTe^4/εσ  –> 1/4^[S/4εσ(1-A)] = [Te^4]^1/4  –>   [S/4εσ(1-A)]^1/4=TeS=Solar Constant=1370 w/m^2/k^4A=Albedo=3ε=Epsilon=1σ=sigma=5.67×10^-8 [(1370)(1-.3)/4(1)(5.67x10^-8)]^1/4 = Te  –>  Te = 255 Kelvins 

CCC Toll Road Thing

Posted in school with tags , , , , on February 6, 2008 by Jamie

I think the toll road should not be built. My first reason is that it will go through the 5th most visited state park in California, which makes no sense. Reason #2 is that the toll road will not relieve any traffic, it will just make it worse. My third reason is that it will destroy the surf at Trestles. The fourth and final reason is that it will wipe out or endanger some species of animals, which is wrong. I probably just threw myself into politics here. Oh well.  

“Vacations” are not always relaxing…

Posted in random with tags , , on February 1, 2008 by Jamie

it’s true. Whenever I go on a vacation, something ALWAYS will go wrong. ALWAYS. The rental car will break down, the plane from Dallas will not take off until 11:00 PM, I will go into a restaurant and there will be really crappy food, etc. so this is my conclusion on Vacations, and how stressful they usually turn out to be for me.
