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 ...
1612 — Santorio Sanctorius makes the first thermometer for medical use. 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]
It is thought, but not certain, that Galileo Galilei discovered the specific principle on which the device is based and built the first thermoscope in 1593. [citation needed] In the 17th century Galileo mentioned to his friend Cesare Marsili that he invented a thermoscope as far back as 1606. [6]
Galileo thermometer: invented by Galileo Galilei in 1593. Toffoli gate: a universal reversible logic gate invented by Tommaso Toffoli. Public toilets: latrines were part of the sanitation system of ancient Rome, placed near or as part of public baths .
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei (/ ˌ ɡ æ l ɪ ˈ l eɪ oʊ ˌ ɡ æ l ɪ ˈ l eɪ /, US also / ˌ ɡ æ l ɪ ˈ l iː oʊ-/; Italian: [ɡaliˈlɛːo ɡaliˈlɛːi]) or mononymously as Galileo, was a Florentine astronomer, physicist and engineer, sometimes described as a polymath.
In June 1609, Galileo's interests shifted to his telescopic investigations after having been close to revolutionizing the science of mechanics. [15] Navigation was an important topic of the time, and many innovations were made that, with the introduction of better ships and applications of the compass, would later lead to geographical discoveries.

The barometer arose from the need to solve a theoretical and practical problem: a suction pump could only raise water up to a height of 10 metres (34 ft) (as recounted in Galileo's Two New Sciences). In the early 1600s, Torricelli's teacher, Galileo, argued that suction pumps were able to draw water from a well because of the "force of vacuum."
