Galileo Galilei
Born: February 15th 1564, in Pisa, Italy.
Died: January 8th 1642, age 78, in Florence, Italy.
At age 22 (1586) Galileo wrote a book named "The Little Balance". This book was written to decribe Archimedes' method of finding the specific gravities.
Galileo passed away January 8th 1642, in florence, Italy.
Galileo also wrote many essays on the theory of motion, but they were never printed. -
Otto Von Guericke
Born: November 20, 1602 in Magdeburg, Germany
Died: May 11, 1686 in Hamburg, Germany
Von Guericke invented a vacuum pump which included a piston and an air gun cylinder with two-way flaps which were used to pull air out of whatever vessel it was conected to, and used it to investigate the properties of the vacuum in many experiments. This occured when he was 48 years old.
Otto passed away at the age of 83.
He invented the first electrostatic generator. -
Evangelista Torricelli
Born: October 15, 1608 in Faenza, Romagna (Italy)
Died: October 25, 1647 in Florence, Italy
Torricelli made a significant contribution to physics by inventing the first barometer. This barometer was a tube, filled with mercury, that sat vertically in a basin of mercury. The height of the mercury would fluctuate with changing atmospheric pressure, that can now be measured in a unit of measure known as the 'Torr'.
Torricelli passed at the age of 39.
Evangelista was left fatherless at a young age. -
Blaise Pascal
Born: June 19, 1623 in Clermont-Ferrand, France
Died: August 19, 1662 in Paris, France
Pascal became a renowned name in science when he clarified the concepts of pressure and vacuum. A unit measuring atmospheric pressure is now known as the 'Pascal',This achievement was made when Pascal was approximately a young 25 years of age!
Only 14 short years later, at the age of 39, Blaise Pascal died.
Aside from a physicist, Pascal was also a mathematician, inventor, writer, and catholic philosopher. -
Christiaan Huygens
Born: April 14, 1629 in The Hague, Netherlands
Died: July 8, 1695 in the Netherlands
Huygens was responsible for the invention of the mamometer ( a device used to measure the pressure of liquids and gases). He invented this when he was 32 years of age.
Christiaan died at the age of 66.
He devised the first working pendulum clock in 1657. -
John Dalton
Born: September 6th 1766, Eaglesfield Cumberland, England.
Died: July 27th 1844, age 77, Manchester, England.
In 1800's, John Dalton discoverd the atomic theory, the constitution of mixed gases. Dalton was 34 years of age during this descovery
He passed away on July 27th 1844, at 77 years of age, in Manchester, England.
John Dalton was also known for "Law of Multiple Proportions, Dalton's Law of Partial Pressures, Daltonism" -
Amedeo Avogadro
Born: August 9, 1776 in Turin, Italy
Died: July 9, 1856 in Turin, Italy
He was responsible for Avogadro's Law which states that the relationship between the masses of the same volume of different gases (at the same temperature and pressure) corresponds to the relationship between their respective molecular weights. He made this law when he was 35 years old.
Amedeo died when he was 79 years of age.
In 1820, he became professor of physics at the University of Turin.
