Barometer, device used to measure atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude. There are two main types of barometers: mercury and aneroid. Learn more about barometers in this article. The aneroid barometer has a circular display that indicates the present number of atmospheres, much like a clock. One hand moves clockwise or counterclockwise to point to the current number of atmospheres. The terms stormy, rain, change, fair, and dry are often written above the numbers on the dial face to make it easier for people to interpret the weather. With a large amount of the student population at Oregon State University now facing economic hardships due to COVID, the university is offering a federal grant to supply students with emergency aid, though not every student is eligible, nor will every person who applies be granted aid.

Evangelista Torricelli became the first scientist to create a sustained vacuum and to discover the principle of a barometer. Torricelli realized that the variation of the height of the mercury from day to day was caused by changes in the atmospheric pressure. Torricelli built the first mercury barometer around Author: Mary Bellis.

The barometer question is an example of an incorrectly designed examination question demonstrating functional fixedness that causes a moral dilemma for the examiner. In its classic form, popularized by American test designer professor Alexander Calandra (–), the question asked the student to "show how it is possible to determine the height of a tall building with the aid of a barometer.". There are various types of barometers such as the water barometer, aneroid barometer, and the mercury mercury barometer, the earliest barometer, was created by an Italian mathematician named Evangelista Torricelli in They are used for measuring altitude, or height above the ground, such as the height of a mountain, and they were often used to measure altitude aboard a hot.
