1617 — Giuseppe Biancani published the first clear diagram of a thermoscope; 1624 — The word thermometer (in its French form) first appeared in La Récréation Mathématique by Jean Leurechon, who describes one with a scale of 8 degrees. [2] 1629 — Joseph Solomon Delmedigo describes in a book an accurate sealed-glass thermometer that uses ...
(Galileo did invent a thermometer called Galileo's air thermometer, more accurately called a thermoscope, in or before 1603.) [1] The instrument now known as a Galileo thermometer was invented by a group of academics and technicians known as the Accademia del Cimento of Florence, [ 2 ] who included Galileo's pupil, Torricelli and Torricelli's ...
A thermoscope is a device that shows changes in temperature. A typical design is a tube in which a liquid rises and falls as the temperature changes.
A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal ...
Attempts at standardized temperature measurement prior to the 17th century were crude at best. For instance in 170 AD, physician Claudius Galenus [1]: 18 mixed equal portions of ice and boiling water to create a "neutral" temperature standard.
1593 – Galileo Galilei builds a first modern thermoscope. But it is possible the invention was by Santorio Santorio or independently around same time by Cornelis Drebbel. The principle of operation was known in ancient Greece. c. 1611 –1613 – Francesco Sagredo or Santorio Santorio, put a numerical scale on a thermoscope.
The first clear diagram of a thermoscope was published in 1617 by Giuseppe Biancani (1566 – 1624); [2]: 10 the first showing a scale and thus constituting a thermometer was by Santorio Santorio in 1625. [5] This was a vertical tube, closed by a bulb of air at the top, with the lower end opening into a vessel of water.
Demiard – an old French unit of volume. When France metricated, it survived in Louisiana and Quebec. The demiard eventually became associated with the American and British half-pint rather than French units.
