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.
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.
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 an Italian [a] astronomer, physicist and engineer, sometimes described as a polymath.
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...
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.
In 1607, Galileo Galilei constructs a thermoscope. In 1643, Evangelista Torricelli invents the mercury barometer. [1] In 1662, Sir Christopher Wren invented the mechanical, self-emptying, tipping bucket rain gauge. In 1714, Gabriel Fahrenheit creates a reliable scale for measuring temperature with a mercury-type thermometer. [2]
