By determining the relative date and temperature of a sample being studied, geologists are able to understand the structural information of the deposits. Thermochronology is used in a wide variety of subjects today, such as tectonic studies, [ 12 ] exhumation of mountain belts, [ 13 ] hydrothermal ore deposits, [ 4 ] and even meteorites. [ 14 ]
Joseph-Nicolas Delisle. The Delisle scale is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). [1] The Delisle scale is notable as one of the few temperature scales that are inverted from the amount of thermal energy they measure; unlike most other temperature scales, higher measurements in degrees Delisle are colder, while lower measurements ...
In 1847, Carl Bergmann published his observations that endothermic body size (i.e. mammals) increased with increasing latitude, commonly known as Bergmann's rule. [9] His rule postulated that selection favored within species individuals with larger body sizes in cooler temperatures because the total heat loss would be diminished through lower surface area to volume ratios.

3.6 TK, temperature at which matter doubles in mass (compared to its mass at 0 K) due to relativistic effects; 5.5 TK, highest man-made temperature in thermal equilibrium as of 2015 (quark–gluon plasma from LHC collisions) [12] 10 TK, 100 microseconds after the Big Bang; 45–67 TK at collapsar of a gamma-ray burst
Antarctica sees a very rapid and abrupt 6 °C increase in temperatures [2] c. 19,000 BC: Last Glacial Maximum/sea-level minimum: c. 20,000 BC c. 12,150 BC Mesolithic 1 period c. 17,000 BC c. 13,000 BC Oldest Dryas stadial (cool period) during the last Ice age/glaciation in Europe. c. 13,000 BC Beginning of the Holocene extinction.
The ideal temperature for sleep is typically between 60°F and 67°F for most adults, says Martina Vendrame, M.D., neurologist and sleep medicine specialist at Lehigh Valley Health Network.
This temperature is achieved in the cores of main-sequence stars with at least 1.3 times the mass of the Sun. [32] The Sun itself has a core temperature of about 1.57 × 10 7 K. [33]: 5 As a main-sequence star ages, the core temperature will rise, resulting in a steadily increasing contribution from its CNO cycle. [25]
