What i know about light

I know that the creator of the light was a person named Thomas Edison, who was told by a teacher”he was too foolish and stupid to learn even the easiest things.”As we can all see, the teacher was wrong. The light bulb was invented in 1879, so is 137 years old in 2016! The light bulb is powered by an energy called electricity, which is dangerous when switched on. Before light bulbs were oil lamps and candles that could somehow set fire. The top of the light bulb is where the light comes out of (the circle), which is activated by a switch or anything similar. Light bulbs are important because they light up places, with low chances of putting them in danger (the light might pop because it’s overheated). This shows that it protects you more.
