This month I am running a challenge about Thomas Edison’s inventions. The student who tells me the most number of Edison inventions, wins a technology challenge prize.
Many students (wrongly) assume that Edison invented the light bulb. This is because we have often heard about the incandescent bulb and Edison. However, Thomas Edison was simply improving earlier inventions of the bulb by scientists such as Humphrey Davy and Allesandro Volta.
Google somewhat contributes to this famous mistake – Try Googling “light bulb inventor.” Who pops up on the right, in a highlighted area about the Incandendescent Bulb?
Perhaps Google aimed at rectifying this by featuring the Google Doodle (below) yesterday for the birthday of Allesandro Volta.
