Thomas Edison tried two thousand different
materials in search of a filament for the light bulb. When none worked
satisfactorily, his assistant complained, “All our work is in vain. We
have learned nothing.”
Edison replied very confidently, “Oh, we have come a long way and we have learned a lot. We know that there are two thousand elements which we cannot use to make a good light bulb.”

An innovation idea of Thomas Edison has a big contribution for the entire world. I have learned from this story that never give up to do anything. If it is wrong experiment, try another type of experiment. keep testing until it is a right one.
