On this date in 1648 Florin Perier demonstrated the barometer. 10 things you might not know about barometers.
The word barometer was coined by Robert Boyle in the mid 1600s by combining the Greek words for measuring and weight.
The first Mercury barometer was created in 1600s by an Italian physicist and mathematician called Evangelista Torricelli, who was a student of Galileo.
Florin Perier was Blaise Pascal’s brother-in-law, married to Pascal’s sister Gilberte. He was the one Pascal persuaded to climb a Mountain to test his theory about air pressure. Pascal himself was in poor health and unable to climb the mountain himself. The mountain in question was the Puy de Dôme, at a height of 4,790 feet (1,460 m).
Before modern barometers, people used simple devices using Water to measure air pressure and tell when a storm was on its way. One such device was the 'Donderglas' ('thunder-glass' in Dutch) or 'Dutch water barometer' consisting of a vessel and a spout. The level of water in the spout would rise or fall depending on the air pressure.
Initially, barometers were used to measure height above sea level, but people started noticing that measurements varied according to the weather. They soon figured out this was a way to predict the weather.
From there, they soon became status symbols; talking points that rich people had on display in their homes.
Barometers with a round display with a needle pointing to weather-terms such as 'stormy', 'Rain', 'change', 'fair', and 'dry' are called aneroid barometers. The aneroid barometer was invented by French scientist Lucien Vidi in 1844. It works by having a sealed chamber that expands or contracts as the air pressure varies, which is connected to a mechanical system including a pointer.
Another type of aneroid barometer is a barograph, which has a revolving drum around which Paper is wrapped, and a nib and ink. The changes in pressure over a period of time can be recorded on the paper as the drum turns.
Many modern smart phones have pressure sensors built into the design to pick up changes in weather and to calculate your current altitude. So you may have a portable barometer in your pocket.
There’s a man in Spain who has gone as far as to have a barometer implant installed in the back of his head. His name is Manel Muñoz and he’s a cyborg artist. In 2017, he had a chip put in that detected pressure changes. At first, the chip was connected to transmitters in his ears so he could tell the air pressure by the sound. I’m guessing this became rather annoying, like tinnitus, which may be why he had it updated with small motors that vibrate directly through his skull. If the left side of his head vibrates, it means low pressure and possible storms, and if the right side vibrates it means the weather will be fine.
