How did Galileo invent the thermometer?
In 1593, Galileo Galilei invented a rudimentary water thermoscope, which for the first time allowed temperature variations to be measured. Today, Galileo’s invention is called the Galileo Thermometer, even though by definition it was really a thermoscope. The buoyancy of water changes with temperature.
How was the thermometer discovered?
The Italian, Santorio Santorio (1561-1636) is generally credited with having applied a scale to an air thermoscope at least as early as 1612 and thus is thought to be the inventor of the thermometer as a temperature measuring device. Santorio’s instrument was an air thermometer.
What is the history of the thermometer?
In 1714, Dutch scientist and inventor Daniel Gabriel Fahrenheit invented the first reliable thermometer, using mercury instead of alcohol and water mixtures. In 1724, he proposed a temperature scale which now (slightly adjusted) bears his name.
Who invented the body thermometer?
Sir Thomas Clifford Allbutt
Sir Thomas Clifford Allbutt (1836–1925) was a celebrated British physician. He spent 20 years working in Leeds during which time he devised the small clinical thermometer.
Who invented the thermometer in 1592?
Galileo GALILEI – 1592 – The thermometer is invented (Galileo, Italy) “The first thermometer was constructed by Galileo. It consisted of a small glass globe fitted with a long tube. The open end of the tube was inserted in water, and the globe was heated until some of the air was expelled from it.
Who invented the first digital thermometer?
The digital thermometer had a patent taken out for it in 1973 by F. Mueller, B. Martin, J. Chandler, R.
Who invented forehead thermometer?
Francesco Pompei of the Exergen Corporation introduced the world’s first temporal artery thermometer, A non-invasive temperature sensor which scans the forehead in about two seconds and provides a medically accurate body temperature.
Who invented thermometer in which year?
The more modern thermometer was invented in 1709 by Daniel Fahrenheit. It was an enclosed glass tube that had a numerical scale, called the Fahrenheit scale. The early version of this thermometer contained alcohol and in 1714 Fahrenheit developed a mercury thermometer using the same scale.
How accurate is a Galileo thermometer?
Its temperature reading range is between 64 and 80 degrees Fahrenheit, and the producer claims it has an accuracy of 4 degrees Fahrenheit.
Who invented the mercury thermometer?
