Gabriel Fahrenheit
Born 24 May 1686; died 16 Sep 1736 at age 50. Gabriel Daniel #Fahrenheit was a #German-Dutch #physicist and #instrument maker (#meteorological). He lived in #Holland for most of his life. He invented the #Alcohol #Thermometer (1709) and #MercuryThermometer (1714) and developed the Fahrenheit #temperature #scale. For the zero of his scale he used the temperature of an equal ice-salt mixture; 30° for the #freezingpoint of water; and 90° for normal body temperature. Later, he adjusted to 32° for the freezing point of water and 212° for the boiling point of water, the interval between the two being divided into 180 parts. He also invented a #hygrometer to #measure relative #humidity and experimented with other liquids discovering that each liquid had a different #boilingpoint that would change with #atmospheric #pressure. www.drbjagadish.com #drbjagadish #masterdoctor #DiabetesClinic #Telemedicine #onlineconsultation #Diabetologist #Odisha #health #awareness
