It has been argued that the light bulb was the greatest invention of all time. The light bulb was invented by Thomas Edison in 1879. It is constructed of a wire filament surrounded by a glass bulb. The wire is heated to a high temperature by an electric wave passing through it. This creates a bright light which is contained by the glass bulb around it. The light bulb has changed the way the world works as a whole. Everybody uses light bulbs, but we don’t really appreciate them as much as we should. Imagine walking down the street at night with no lights anywhere. There are hundreds of situations where we need lights; without them we cannot live life as we know it.

Some people say that it is ridiculous to think that the light bulb was the greatest invention of all time. Can’t we use candles? Penicillin, indoor plumbing, and the telephone are often heard as well. Penicillin has saved millions of lives; indoor plumbing revolutionized the way we defecate; and the telephone has allowed us to talk to people hundreds of miles away, as if they were right next to us. Some also believe that writing was the greatest invention of all time. Before writing, we could not record any of our knowledge. This means that when people died, any stories or important information that they didn’t pass by word of mouth was gone forever.

I do not believe that the light bulb was the greatest invention of all time. The personal computer including the world wide web, in my opinion, was the most important invention of all time. It allowed us access to an amazing wealth of information and is a key player in the technological revolution. The internet has changed the way humans learn and communicate for the better and it is a major part of the world we live in today.
