Universe (Radiation (Gamma (The uses of gamma (Gamma radiation is used for…

- - - - Ultra Violet is 10% of the suns light so we need it for light.
      - Triggers vitamin D, helps skin conditions, helps animals, helps your mood, and aids insects.
      - But to much of the this radiation can cause sun burns, can tan your skin, can give you skin cancer and eye damage if you look at the sun.
  - - - The microwave radiation is used for cooking food in microwave ovens.
      - The Microwave oven have 2.45 billion hertz and if it leaks 10 hertz it can be harmful. Maybe can cause cancer.
  - - - Gamma radiation is used for chemo therapy and the doctors put the radiation in your body and it kills all of the bad stuff, plus your good stuff too so it makes you really sick for a long time.
  - - - In the hospital they shoot the x-rays like a picture and they go through your skin and bounce off of the bones and go through the cracks in the bone and then they show you what is broken or damaged in the bone.
- - - - Energy
    - - Mass
    - - Speed of light
- - - - Kepler
        
        His theory is that the planets move around the sun which is Tycho Brahe. This made people mad because the other people believed that the earth was in the middle of our universe.
        
        Planets move in elliptical orbits with the Sun at one focus
      - Newton
        
        Publishes the laws of motion and gravity that are used to predict the motion of the moon and planets.
        
        Newton's law of universal gravitation states that every mass attracts every other mass in the universe, and the gravitational force between two bodies is proportional to the product of their masses, and inversely proportional to the square of the distance between them.
      - Galileo Galilei
        
        Galileo Galilei found out there were stars orbiting Jupiter which proved there are other things in our universe which made lots of people mad, the other people thought that the earth was in the middle and there was nothing else out there that matters.
        
        He built an improved telescope that helped him see the moons of Jupiter, rings of Saturn, the phases of Venus, sunspots and the rugged lunar surface.
      - Einstein
        
        In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
        
        He is the person that created the equation E=mc2. E(energy)=m(mass)c2(speed of light).
      - Ptolemy
        
        Ptolemy's theory was he thought that the earth was in the middle of the universe.
      - Aristotle
        
        He believed that the earth was in the middle of the universe and the stars and planets all orbited the earth.
