Основное содержание урока

If you stand at the end of a train track and look down it, what do you see? The further down the tracks you look the closer the two tracks seem to be. Eventually, they appear to touch, but we all know that they don’t really. Our eyes are simply playing tricks on us. Sight is a complicated thing! Our eyes work together with our brain to understand what we are seeing. When we watch TV, for example, our brain learns to see movements but in reality we are see a series of individual images moving very quickly. That’s why we have so much fun with optical illusions: our brain “sees” things that aren’t really there, or fails to see something that is there. This is why we can have fun with optical illusions! They can teach us that there is often more than one way to see things. If you and your friend have different opinions about something, you just see things in different ways!
