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 density of the surrounding liquid as the temperature changes.
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.
1638 — Robert Fludd the first thermoscope showing a scale and thus constituting a thermometer. 1643 — Evangelista Torricelli invents the mercury barometer 1654 — Ferdinando II de' Medici, Grand Duke of Tuscany , made sealed tubes part filled with alcohol , with a bulb and stem, the first modern-style thermometer, depending on the ...
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.
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.
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]
Galileo. 1607 – Galileo Galilei constructs a thermoscope. Not only did this device measure temperature, but it represented a paradigm shift. Up to this point, heat and cold were believed to be qualities of Aristotle's elements (fire, water, air, and earth). Note: There is some controversy about who actually built this first thermoscope.
In the late 16th and early 17th centuries, several European scientists, notably Galileo Galilei [4] and Italian physiologist Santorio Santorio [5] developed devices with an air-filled glass bulb, connected to a tube, partially filled with water. As the air in the bulb warms or cools, the height of the column of water in the tube falls or rises ...
