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.
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.
Vapour pressure thermometer Density Galileo thermometer [45] Thermochromism Some compounds exhibit thermochromism at distinct temperature changes. Thus by tuning the phase transition temperatures for a series of substances the temperature can be quantified in discrete increments, a form of digitization. This is the basis for a liquid crystal ...
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]
1922 – Supersonic wind tunnel is invented in National Physical Laboratory (United Kingdom). 1926 – Einstein solves the tea leaf paradox. 1925 – Jakob Ackeret publishes the theory of supersonic airfoils. 1926 – Erwin Madelung relates quantum mechanics with hydrodynamics through his quantum hydrodynamics equations, known as Madelung ...
I believe the original source is Life of Galileo by Vincenzo Viviani, which says (in translation) "about the time Galileo took the chair of mathematics in Padua at the end of 1592, he invented the thermometer, a glass containing air and water". Notice the word "about", the fact that it was the end of 1592, and the fact that the process of ...
