November 9th is the International Day of Inventors. To celebrate it, we have devoted one lesson in each subject to talk about some important inventors and their minds' children. We have talked about such luminaries as Thomas Edison but also about other less renowned inventors, without whom things like a safety pin or a can opener wouldn't have been invented.

By the way, why is that day celebrated on the 9th of November? It is the birthday of the Austrian-born inventor and Hollywood actress Hedy Lamarr whose main invention was the frequency-hopped spread spectrum 1942. In the USA, however, it is celebrated February 11th, the birthday of Thomas Edison.
