Have you had this experience? You are watching a movie. A man is shooting on the screen. The picture is so real that you think he is shooting at you. Or a car is speeding on the screen and at one point you are afraid that it will hit you. Yes,it’s a three-dimensional(3D) movie.
　　3D movies use special technology to make pictures seem more real and exciting than two-dimensional ones.They are fun to watch, but do you know how they are made? It is much easier to understand if we do an experiment.
　　Hold one of your fingers up at arms length and close one eye. Then try closing the other eye. As you switch(切换) between open eyes, you should see your finger “jumping” left and right against the background.
　　This happens because our two eyes are about 4cm away from each other. The separation(分开) causes each eye to see the world from a different angle. The brain puts these two views together. What you see becomes three-dimensional.
　　3D movies are made using two video cameras at the same time, which creates two different images. When the movie plays in a cinema, two projectors(放映机) put the two images on the screen. With a pair of 3D glasses, the two images are separated and each image only enters one eye. Your brain puts the two pictures back together, and the pictures on the screen become three-dimensional.

So far we can only see 3D movies in the cinema with a special screen and projector. But soon, we will be able to watch them in our living rooms.

    Suppose the year is 1666 and we can see a student called Isaac Newton. He’s away from his university for a holiday and at home with his family. Isaac Newton continues to study at home. He enjoys physics and thinking about the mysteries of the world.

    On a day there is rain and sun at the same time, so he sees a beautiful rainbow( 彩虹 )in the sky. It has many different colors. He is told that there are five. Newton wants to have his own rainbow because he wants to look at it closely. He decides to do an experiment. On a sunny day he goes inside a small room and makes the room very dark. Then he makes a small hole and the sun comes inside; it’s a small ray of light. It’s white. Newton takes a prism( 棱镜 ) and holds it up to the light. The ray of light goes through the prism, but it isn’t white now---there are many colors. The prism has split up ( 分解 ) the white into different colors: Newton has a rainbow.

    Newton looks at his rainbow carefully. He can see more than five colors, and he can see seven. He says the colors are: red, orange, yellow, green, blue, indigo and violet.

    But Newton is a scientist and he’s always very interested in how things work.  He has his rainbow but he wants to know more. So he takes another prism and holds it up to the rainbow. The rainbow goes through the second prism, but it isn’t colorful now---it’s white again. The prism has joined up the colors back into white light. Newton is the first person to understand that light is a combination ( 结合 ) of all the rainbow colors together.
