It is true that it was invented around 1500, but it underwent several changes throughout history to reach what we see today.
He December 22 is World Thermometer Day. This instrument was designed almost 5 centuries ago and is very useful for checking the feverish state of people. It is also used to measure environmental temperature and not just human body temperature.
It is considered one of the great health advances in history. It has a central role when it comes to diagnose pathological diseases. Etymologically, its name means heat (thermos) and measurement (metron). So its literal translation would be a measure of heat.
What is the origin of World Thermometer Day?
He Discoverer of this artifact was Galileo Galileialthough he called it a thermoscope, and it was used to measure the temperature of a particular environment. It consisted of a glass tube that had one open side and a bulb at the other end. In 1624, Jean Leurechon, a French Jesuit and mathematician, named it the thermometer.
During 1714, the Polish physicist and engineer Gabriel Fahrenheit created what is now known as the mercury thermometer. It has a bulb and a sealed metal tip, which when in contact with a higher temperature, causes the mercury to dilate and expand inside this device. In this way, a rise of this material can be observed, which according to a measurement scale, will denote a particular thermal value.
The reason for choosing December 22 to honor this artifact is unknown.
Who was the creator of the thermometer
Galileo Galilei
The first inventor was Galileo Galilei, but he called it a thermoscope and used it to measure ambient temperatures. The person who adapted it to measure body temperature and named it a thermometer was Jean Leurechon, a French Jesuit and mathematician.
But the thermometer that we use today, or at least until recently, is the one created by Gabriel Fahrenheit, with the mercury dilation system.
