BR 1-19The Shocking story of Electricity

Useful electricity(P.31)




I was read this book first time. Electricity is all around us, making all kinds of machines work. But what is it? And where does it come from? Wherever you look, you'll see things that run on electricity... and billions of people around the world have an electricity supply in their house. Less than 200 years ago, though, there was no electricity supply at all - and no electrical gadgets either. So people used other things. There has always been electricity in nature. Lightning, for instance, ia a giant electric spark. Back in prehistoric times, people could see how powerful lightning was. But they had no idea it was a form of electricity - or that electricity could be useful to them. They thought lightning was a punishment, sent by their gods. In 600BC, an ancient Greek scientist named Thales made a surprising discovery. Thales found that if he took a piece of amber and rubbed it with cat fur, the amber could pull things closer to it. It could even pick up light objects such as hairs or seeds. The Greeks were amazed by the amber's power to pick up objects. They also found that, if they rubbed the amber a lot, they sometimes saw a little spark. Thales and his friends had discovered a kind of electricity, although they didn't realize that's what it was. Some even claimed that if amber had such amazing powers, it must have feelings.


I was read this book first time. electric is very important I think. I want to read many books after this.
