Thermometry or temperature measurement is important to a wide range of activities, including manufacturing, scientific research, and medical practice. The accurate measurement of temperature was developed only recently.

 

Fun Fact:
Galileo invented the first thermometer. In his instrument, the changing temperature of an inverted glass vessel produced the expansion or contraction of the air within it, which in turn changed the level of the liquid with which the vessel’s long, open-mouthed neck was partially filled. This general principle was perfected in succeeding years by experimenting with liquids such as mercury and by providing a scale to measure the expansion and contraction brought about in such liquids by rising and falling temperature.
