Daniel Gabriel Fahrenheit – Thermometer inventor

Daniel Gabriel Fahrenheit – Thermometer inventor – In 05.24.1686 was born physicist and inventor, Daniel G. Fahrenheit. He invented the mercury thermometer and developed a temperature scale, called his name. Produced thermometers, barometers and altimeters. He described the phenomenons of supercooling water and dependence of boiling water and pressure.

Copper cube cryostat - Cryostat construction

Copper cube cryostat

Copper cube cryostat – Italian researchers from the Institute of Nuclear Physics (INFN). Put the copper cube with a volume of 1 and 400 kg in a special cryostat designed so that extremely cool down items. This is the first cryostat, which maintains the temperature course barely above the absolute zero (0 Kelvin = -273.15 ° C). In the case of copper cube thermometer stopped just 6 milikelwinach, or 0.006 degree above absolute zero.

Allow understand another person position

Allow understand another person position – In the first half of 2015. We found the mirror neurons so allow us to understand the position of another person that may even lead to a change of temperature of some parts of the body. Researchers at the University of Sussex in the UK, a group of 36 people showed three-minute films in which the actors put their hands in hot water, hot and ice, and the researchers measured the viewers heart rate and body temperature. When the subjects saw the film as a person shivering in the cold, dipping his hands in cold water, they felt chills. But it was not only a subjective impression. This change was detected thermometers. Temperature hand some test decreased by as much as 0.2 °C.
