How it works how does it affect us, scientist spend their lives trying to invent something better, or for easier use, the reason is that we hardly know how important it is to have created and invention for example light, but because we are so used to having light everywhere we go, its not important. we loose interest in who did it and really what was the background history and what was their knowledge in creating Science!
