Kirchhoff, Gustav Robert (1824-1887), a German physicist. Investigations in spectrum analysis enabled Kirchhoff and Robert Wilhelm Bunsen to discover the elements cesium (1860) and rubidium (1861). Kirchhoff formulated laws concerning heat radiation and electrical circuits. He was born in the East Prussian city of Königsberg (now Kaliningrad, Russia) and studied at the university there. Kirchhoff taught physics at the universities of Breslau, Heidelberg, and Berlin.
Albert Einstein was a pretty smart guy. When you look up the word "genius" in the dictionary, so the saying goes, it's a pretty safe bet you'll see Einstein's mug. Think you’re smart enough to take on a quiz about the famed thinker?
He was born exactly 300 years after Galileo died. He has yet to be awarded a Nobel Prize, although he was awarded a guest spot on “The Simpsons.” What else do you know (or not know) about this acclaimed physicist?
