A Celsius Galilean thermometer in two degree gradations. A risen orange orb denotes 24 °C. A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the ...
Philo of Byzantium is credited with the construction of the first thermoscope (or Philo thermometer), an early version of the thermometer. [6] It is also thought, but not certain, that Galileo Galilei discovered the specific principle on which the device is based and built the first thermoscope in 1593.
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 ...
The 17th century saw the development of the barometer and the Galileo thermometer while the 18th century saw the development of the thermometer with the Fahrenheit and Celsius scales. The 20th century developed new remote sensing tools, such as weather radars, weather satellites and wind profilers, which provide better sampling both regionally ...
1593 – Galileo Galilei invents one of the first thermoscopes, also known as Galileo thermometer [1] 1650 – Otto von Guericke builds the first vacuum pump 1660 – Robert Boyle experimentally discovers Boyle's law, relating the pressure and volume of a gas (published 1662) [2]

Something (a CO monitor, not that that's relevant) inexplicably fell off the wall and knocked the Galileo thermometer onto the floor, where it smashed, disgorging the contents onto the carpet. I mopped it up as best I could, expecting it was water, but a) though odourless it felt more like a very light oil and b) the carpet is now "lifting" as ...
