Galileo Galilei
Galileo Galilei was a famous mathematician, philosopher astronomer, and physicist. He was born on February 15, 1564 and died at the age of 77 from heart palpitations and a fever on January 8, 1642. -
Period: to
Ottovon Guericke
Ottovon was a German scientist, inventor, and politician. He was born on November 20, 1602 and passed away peacefully on May 11, 1686. -
Period: to
Evangelista Torricelli
Evangelsita was the physicist and mathematician who was born on the 15th of October, 1608 and died on the 25 of October, 1647 from typhoid fever. -
Period: to
Blaise Pascal
Blaise was a French physicist, mathematician, inventer, philospher and child prodigy. He was born on June 19, 1623 and died on August 19, 1662 from a mix of tuberculosis and stomache cancer. -
Period: to
Christiaan Huygens
Christiaan was a Dutch astronomer, mathematician, physicist and horologist who was born on April 14, 1629 and died on July 8, 1695 from serious illness. -
Galileo's Contribution
Galileo (age 66) developed the suction pump which was used to draw underground water into a column. During the making of his invention he became interested in why there was a limit to the height the water could travel up the column. -
Evangelista's Contribution
Evangelista (age 35) was responsible for developing the first ever barometer. He continued Galileo's work learning that the reason Galileo's pimp could only draw water to a certain point, was because of atmospheric pressure. He then made a closed-end tube filled with mercury which was placed in a shallow dish filled with liquid mercury. The height the mercury reached in the column equaled the atmospheric pressure exerted on the mercury in the pan. -
Otto von's Contribution
Otto von (age 35-37) invented a pump that could cause a vacuum so immense that a team of 16 hourses could not seperate two metal sphere's apart. He learned that the hemispheres were held together by the atomsphereic pressure, not the vacuum. -
Blaise's Contribution
Blaise (age 25) tested Evangelista Torricelli's barometer by travelling up and down a mountain in southern France. As he moved down the mountain he saw that the atmospheric pressure increased. Later, the SI unit of pressure (Pascal) was named after him. -
Christiaan's Contribution
Christiaan (age 32) made the manometer to study the elastic forces between gases. -
Period: to
John Dalton
John was an English chemist, meteorologist and physicist who was known for his work on modern atomic theory. He was born on September 6, 1766 and died from a stroke on July 27, 1844. -
Period: to
Amadeo Avogadro
Amadeo was a Italian servent who contributed mostly to molecular theory. He was born on August 9, 1776 and died on July 9, 1856. -
Period: to
Joseph Louis Gay-Lussac
Joseph was a French chemist and physicist born on December 6, 1778. He passed away on May 9, 1850 -
John's Contribution
John (age 35) reported that in a mixture of gases the total pressure of all the gases is equivalent to the sum of the pressure of each gas singularly. The presssure each gas is exerting is named the partial pressure. -
Joseph's Contribution
Joseph (age 30) speculated the law of combining volumes. He realized that two volumes of hydrogen combined with only one volume of oxygen to form two volumes of water. -
Amadeo's Contribution
Amadeo (age 35) proposed, based off of Joseph's three experiments conducted earlier, that the pressure in a container is proportinate with the number of particles in the container (known as Avogadro's Hypothesis). You can visually observe this when blowing up a balloon, ball or tire (the more air in the container the larger the container becomes because of increasing pressure).
