In the history segment, Cindy and Jeremy discuss Augustin-Jean Fresnel, the brilliant French civil engineer and physicist who is best remembered for the invention in the 1820s of a type of lens that increased the visibility of lighthouses and saved countless lives. There's also another trivia contest with a chance to win prizes.
