The now very useful and handy thermometer was not a single invention but rather a development. It was thanks to the initial understanding of Hero of Alexandria (10-70 AD) about the principle of air expanding and contracting and his demonstration of a closed tube partially filled with air that had its end in a container filled with water. The said mechanism was later on used to determine the coldness or hotness of the air. It contains materials that in some way changes when it is cooled or heated. The substance inside the tube contracts when exposed to cold and expands when exposed to heat. The fixed points on the scales were based on the temperatures of boiling water for the hottest and melting ice for the coldest. The thermoscope is the earlier version of the thermometer it only showed differences in temperature particularly when something is getting hotter while its improved version, the thermometer, provides a much accurate temperature measurement including degrees. Santorio Santorio an Italian inventor came up with the idea of putting a numerical scale on the instrument. In 1593 Galileo Galilei invented the water thermometer which, for the first time, allowed temperature variations to be measured. Advancement went on and on up until now, thermometers are broadly used in different industries to monitor processes in medicine, scientific research, and even meteorology. In fact, by 9.1% a thermometer is still part of the top picks to get a hold of at the beginning of a season and garnered 14% for most used smart health devices.
