Anders Celsius was a Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germany, Italy and France. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 proposed the Centigrade temperature scale which was later renamed Celsius in his honour.
Daniel Gabriel Fahrenheit FRS was a physicist, inventor, and scientific instrument maker, born in Poland to a family of German extraction. Fahrenheit invented thermometers accurate and consistent enough to allow the comparison of temperature measurements between different observers using different instruments. Fahrenheit is also credited with inventing mercury-in-glass thermometers more accurate and superior to spirit-filled thermometers at the time. The popularity of his thermometers led to the widespread adoption of his Fahrenheit scale attached to his instruments.
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the European physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride. The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F.
Thermodynamic temperature is a quantity defined in thermodynamics as distinct from kinetic theory or statistical mechanics.
The mercury-in-glass or mercury thermometer is a thermometer that uses the thermal expansion and contraction of liquid mercury to indicate the temperature.
Cataclysm is derived from the Greek katá, 'down, against', and klyzō, 'wash over, surge'. It may refer to:
Moebius, Mœbius, Möbius or Mobius may refer to:
The year 1742 in science and technology involved some significant events.
The year 1741 in science and technology involved some significant events.
The Delisle scale is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). Delisle was the author of Mémoires pour servir à l'histoire et aux progrès de l'Astronomie, de la Géographie et de la Physique (1738). The Delisle scale is notable as one of the few temperature scales that is inverted from the amount of thermal energy it measures; unlike most other temperature scales, higher measurements in degrees Delisle are colder, while lower measurements are warmer.
Celsius is a small lunar impact crater that is located in the rugged terrain in the southern hemisphere on the Moon's near side. It is named after Swedish astronomer, physicist and mathematician Anders Celsius. It lies less than one crater diameter to the south-southwest of the crater Zagut, and due north of Büsching.
Frost may refer to two distinct weather phenomena:
William Shakespeare (1564–1616) was an English playwright and poet.
Olof Celsius was a Swedish botanist, philologist and clergyman. He was a professor at Uppsala University, Sweden. Celsius was a mentor of the botanist and scientist Carl Linnaeus. Celsius wrote his most famous book on biblical plants, Hierobotanicon, in 1745–47. Celsius was also a prominent runologist.
Meteorological instruments, including meteorological sensors, are the equipment used to find the state of the atmosphere at a given time. Each science has its own unique sets of laboratory equipment. Meteorology, however, is a science which does not use much laboratory equipment but relies more on on-site observation and remote sensing equipment. In science, an observation, or observable, is an abstract idea that can be measured and for which data can be taken. Rain was one of the first quantities to be measured historically. Two other accurately measured weather-related variables are wind and humidity. Many attempts had been made prior to the 15th century to construct adequate equipment to measure atmospheric variables.
The degree Celsius is the unit of temperature on the Celsius scale, one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale. The degree Celsius can refer to a specific temperature on the Celsius scale or to a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who proposed the first version of it in 1742. The unit was called centigrade in several languages for many years. In 1948, the International Committee for Weights and Measures renamed it to honor Celsius and also to remove confusion with the term for one hundredth of a gradian in some languages. Most countries use this scale.
Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology. Empirical scales measure temperature in relation to convenient and stable parameters or reference points, such as the freezing and boiling point of water. Absolute temperature is based on thermodynamic principles: using the lowest possible temperature as the zero point, and selecting a convenient incremental unit.
The Fujitsu Celsius is a line of laptop and workstation computers manufactured by Fujitsu. The brand name has also been used for graphic accelerators.
Anders Spole was a Swedish mathematician and astronomer. He was born at a farm in Målen, the son of blacksmith Per Andersson and his wife Gunilla Persdotter. At the age of twelve he started studying at Jönköpings skola and was sent to the University of Greifswald in 1652. After three years of studies he continued at other universities in Prussia and Saxony, until his return to Barnarp in 1655, where he started preaching in the local church. He continued to study mathematics at Uppsala University, while at the same time being a tutor baron Sjöblad's sons. In 1663, he became a master craftsman of fireworks and the arts of navigation. The following year he accompanied the young Sjöblads on their peregrination around Europe.
