In this invention series you will know about the invention of Clinical Thermometer. Who is the Inventor of Clock? The inventor of Dynamite, Electric Bell and much more.
Invention of Clinical Thermometer
The famous Italian astronomer Galileo invented The first known thermometer in 1593. It was named a thermo scope. But since it was not very accurate, alcohol thermometers were developed in 1641. It was far more accurate.
The first mercury thermometer was developed by Gabriel Daniel Fahrenheit, a native of Danzig. Mercury with it’s properties of a low freezing temperature ( -38.8 degree C/37.8 degree F) and a very high boiling point ( 357 degree C/675 Degree F) was an ideal liquid metal that could be contained in a tube.
The wide variation in a temperature was ideally suited. In the Fahrenheit system of measuring temperature, the water freezes at 32 degree F and boils at 212 degree F. Thomas Albert just used the mercury thermometer to measure human temperature.
Clock
Clock In 725 AD, a Chinese monk named Yi Xing developed what one could call the most advanced precursor of the mechanical clock. Later a French Benedictine monk Gerbert d’Aurillac designed a system of gears run by counter balanced weights.
This invention has been attributed as the first mechanical clock in the history of science. The clock that struck a bell on every hour was recorded in 1120, in Cite au in France. These were large fixed devices. Italian architect, Filippo Brunelleschi was the first to introduce the spring driven clock in 1410 at Florence.
The pendulum based mechanical clock was introduced in 1657 by the Dutch inventor and astronomer, Christian Huygens.
In 1840, Scotsman Alexander Bair ( 1818-1903) invented the first electric clock. Antoire Redier made the first spring driven alarm clock in France in 1847. In 1890, the first electric alarm clock was introduced.
Computer
The ideas and devices by many engineers and scientists led to the invention of the computer. The first electric computer was devised in 1888 AD by an American named Herman Hollerith.
The first semi electronic computer was developed by John Atanasoff in 1944 AD. but the first fully electronic computer was developed in 1946 by two American Engineers Presper Eckert and John Mauchly.
Contact Lenses, Cross words and Dynamite
AE Fick invented The first contact lenses in 1887 but were not very successful. In about 1950, lenses introduced which covered only the cornea and floated on a layer of tears. These lenses, only 7-10 millimeters in diameter of 0.1 to 1 mm thick can usually be won all day without being removed.
Cross words the editor of an American newspaper invented the first crosswords in 1913.
Alfred Nobel of Sweden invented dynamite in 1867. Dynamite is today used widely for various kinds of explosions. It is particular useful in the mining industry. Dynamite explosions are used to access mineral deposits deep below the surface of the earth.
Electro Magnetism & The electric Bell
Magnetism is an important force in nature. Electromagnet were invented by an English Electrician named William Sturgeon in 1825 AD.
The most common type of electric Bell is the door bell seen by us in houses. The switch at the door is connected by electric wires to an electric circuit that Operate the bell. Electric Bell invented in 1876 AD.
