About the light bulb:Many people have made a light bulb making it better every time it is improved. The trick was to find something that will not burn out so fast so the light light bulb will last longer. In 1878 the inventor Sir Joseph Wilson Swan an English Physicist was the first person to invent the first long lasting light bulb that lasted 13.5 hours. But he used a carbon fiber filament derived from cotton. Thomas Edison in 1879 improved it by Inventing a Carbon filament that burned for forty hours. This made the light bulb last a lot longer then Sir Joseph Wilson Swan light bulb.
