Who invented Barometer?

Answer 1

torricelli

Answer 2

An Italian Scientist called Evangelista Torricelli invented the mercury barometer in 1643. He used a column of water in a tube 34 ft (10.4 m) long. This inconvenient water column was soon replaced by mercury, which is denser than water and requires a tube about 3 ft (0.9 m) long.

Torricelli had set out to create an instrument to measure the weight of air, or air pressure, and to study the nature of vacuums. He used mercury, perhaps on a suggestion from Galileo Galilei, because it is significantly denser than water. To create a vacuum with water takes a column over 30 feet long, while with mercury it takes less than four feet.

Answer 3

"...This concept of "decreasing pressure means bad weather" is the basis for a primitive weather prediction device called a weather glass or thunder glass. It can also be called a "storm glass" or a "Goethe thermometer" (the writer Goethe popularized it in Germany)....."

Barometer — Inventor: Evangelista Torricelli

Answer 7

Blood pressure and vacuums measured in millimeters of mercury are still called torrs in honor of Torricelli, who observed the reaction of an inverted tube of mercury (a barometer) while being carried up a mountain.

"Torrs - millimeters of Mercury - [Used for Blood Pressure and
vacuums]
(Named in honor of Evangelisti Torricelli.)"
