Science Counts

Many scientists have tried to invent invisible objects, but they haven’t done it. One scientist at Tokyo University tested cameras on a coat. The cameras filmed objects behind the coat and showed them on the front of the coat. Unfortunately, the coat wasn’t very comfortable! The car manufacturer Mercedes also tried these cameras with a car. They put the camera on one side of the car and showed the images on the other side. But as you can see in this photo, the wheels aren’t invisible. 

With all the cars on the road and the problems of traffic, why haven’t flying cars become popular? One reason is because cars are very heavy so they are difficult to fly. There are other problems as well. Cities have roads for cars, but they don’t have runways. And we have so many problems on our normal roads, do we really want the same problems in the sky?

Teleporting is moving objects and people from one place to another without transportation or walking. Teleporting is a very fast way to travel, but scientists haven’t discovered how to do it. Solid objects are made of atoms and with teleporting you have to move each atom one by one. A human being is made of trillions of atoms, so it’s very difficult and scientists don’t have the answer at the moment. 

Actually, scientists have invented robots, so why don’t we all have them? Probably because the technology is very expensive and the robots often break down. But many companies in Japan have made prototype robots for houses. They wash clothes, switch on the TV, turn off the lights and change the music. Many scientists think we can all have a robot servant in our home in about ten years.
