Nicolas-Léonard-Sadi

Nicolas-Léonard-Sadi Carnot published Reflections on the Motive Power ofFire, in 1824, the first scientific analysis of steam engines, laying thefoundations of thermodynamics.Carnot performed quite a feat,He developed a cycle complete,From torrid to cold,His theories do hold,And thus he's remembered in heat.

Antoine-Henri Becquerel

Antoine-Henri Becquerel discovered natural radioactivity from uranium in1896. A uranium compound exposed a photographic plate through a lightproofwrapper.Becquerel was having a go,At what made substances glow,With uranium he played,And discoveries he made,But that was the end of his show.Cyrus Hall McCormick invented his harvesting machine, the reaper, in 1831.The reaper revolutionized farming, by allowing fewer workers to operatelarger farms.McCormick invented the reaper,And the wheat fields grew wider and deeper,The farmers got lazy,And drank themselves hazy,But his gadget was still a keeper.

Albert Einstein

Thomas Edision

Thomas Edison, Working in Menlo Park, NJ (now part of Edison Township)perfected incandescent lighting in 1879, improving on Swan's (and other's)efforts. He then devised the electrical generation and distribution systemto make it useful.Tom Edison thought he was bright,He invented the electric light,Then, to his chagrin,When turning in,His wife said, "I'll be reading tonight."
