This allows scientists to predict weather patterns. If you have significant body temperature changes, it may indicate an infection. Health wise, it also tells us if our body is within a safe temperature range. At the beginning of the 17th century, there was no real way to measure heat.
But fueled by the growing need to measure its absence or intensity, many notable thinkers paved the way for its development. It is thought, but not confirmed, that Italian astronomer and engineer Galileo Galilei created the thermoscope around Though many sources say he invented it, the thermoscope is best regarded as the invention of a learned circle in Venice which included Galileo, Santorio Santorio, Giovanni Francesco Sagredo and Fra Paolo Sarpi, among others.
What were its limitations? It did not provide any precise measurement, which is why the instrument was not considered an actual thermometer. The thermoscope only indicated temperature differences without a scale, allowing observers to note if an object is getting hotter or cooler.
In , Italian physician Santorio Santorio invented the first thermometer. Throughout his life, he developed other measuring instruments such as a wind gauge and a water current meter called the pulsilogium. Santorio is the first to employ a numerical scale to a thermoscope, which later developed into the modern thermometer.
It was regarded as the first clinical thermometer. However, it did not have a standardized scale and was deemed inaccurate.
While it was possible to measure temperature, people did not have clear understanding of fixed temperature points throughout the 17th century. Back then it was difficult to create a thermometer with the same diameter along its length.
This meant that early thermometers din not have a standard size. However, over time they realized that the thermometer had fixed points when they used it on boiling and freezing water. Boiling and freezing points were selected because they were the easiest to observe.
Researchers confirmed that the points were the same even when they moved to different places using the same thermometer. They also noticed the effects of altitude and air pressure on temperature. By the early 18th century, scientists started developing standard temperature scales. Around this time, thermometer production has improved, while the fixed points allowed scientists to establish a baseline. Today, the fixed points are used to calibrate modern thermometers.
