What is Barometer?
In this modern age the barometer is not exactly competitive with smartphones, computers and other entertainment devices. It is probably an all but forgotten vital piece of equipment that only weathermen remember and use.
What a barometer does is measuring air pressure. The higher the air pressure the better the day will be. The lower the air pressure, make sure you have your umbrella with you and dress warmly.
There isn’t just one type of barometer
Barometers do not multiply like rabbits, but there is more than one variation. You can have a vacuum oil model, micro electro mechanical system, the water based barometer, the aneroid and the most common one; the mercury barometer.
Each one has their own specific uses. The vacuum pump oil barometer has the reputation of being world’s tallest barometer. The micro-electro-mechanical system is the inspirer for the barometer in smartphones, iPhones smartwatches.
Who invented the barometer
As far as we know there are only three types of barometer. The aneroid barometer was invented in 1844 by Lucien Vidi, a French scientist. His measuring tool doesn’t work with liquids but includes a spring so that the beryllium and copper container does not completely collapse.
The rise and fall of the air pressure caused the metal box to expand or contract. Thus Vidi was able to see the changes in air pressure and could predict the weather. He added a needle to make measuring the air pressure much accurate.
Gasparo Berti came up with the water barometer around the same time or two years before the mercury barometer was invented. He invented this barometer roughly 200 years before the aneroid model.
The most common and probably the most used barometer in the world was invented by Evangelista Torricelli. The word “Barometer” took place in literature since then. The invention of the mercury barometer took place in approx. 1643.
Torricelli found that a continuous vacuum and different amounts of air pressure influenced the level of the mercury inside the tube. After watching the levels of the mercury, he found that he could predict the weather conditions in the coming days.
Thus, a weather predicting tool to help society was born.
Some final words
As far as we know; Rene Descartes also thought and wrote about a barometer but it is not known if he built an actual one. None survive if he did. The barometer has turned out to be an excellent weather predicting measuring device to help people to plan their tasks, flights and many other activities.
It has made life a little easier knowing what weather may be coming the next morning.
