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]
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.

The Cimento published a manual of experimentation which began the process of standardizing processes, instruments and measurements throughout Europe. [2] Their motto Provando e riprovando means “proving and disproving”, i.e. providing proofs of true facts and confuting false ones, while a literal translation may read "trying and trying again".
Justus Sustermans – Portrait of Galileo Galilei, 1636. Galileo replied to Castelli with a long letter laying out his position on the relation between science and Scripture. By 1615, with the controversy over the Earth's motion becoming more widespread and increasingly dangerous, Galileo revised this letter and greatly expanded it; this became ...
Not until the works of Johannes Kepler (1571–1630) and Galileo Galilei (1564–1642) was Ptolemy's manner of doing astronomy superseded. The use of more advanced tables and mathematics would provide the impetus for the establishment of the Gregorian calendar in 1582 (primarily to reform the calculation of the date of Easter ), replacing the ...
