Fahrenheit, Gabriel Daniel (1686-1736), a German physicist. In 1714, he devised the Fahrenheit scale for measuring temperature and originated the use of mercury instead of alcohol in thermometers. He is also credited with discovering that a liquid's boiling point changes with the atmospheric pressure. Fahrenheit was born in Danzig (now Gdansk, Poland). He lived in Holland and England for many years, working as an instrument maker. Fahrenheit was elected to England's Royal Society in 1724.
The man immortalized on the left was behind the three laws of motion and the universal law of gravitation. He was also competitive, temperamental and fascinated with alchemy. How well do you know Newton?
He's ventured to the abyss of black holes, wagered on the information paradox and floated around in zero gravity. Meet the man, the legend, the super scientist: Stephen Hawking.
