1627 – Boyle – bio

Robert Boyle was born in 1627 in Ireland and was known primarily as a chemist and his formulation that is called, “Boyle’s Law”. This describes the inverse relationship between the pressure and the volume of a gas. Boyle discovered that sound does not travel in the absence of air but that light does. His work […]

-3500 – glass

Naturally occurring volcanic glass (obsidian) was use before we learned to make glass around -3,500 in Egypt and Mesopotamia. The earliest form of glass made by humans was probably glazes that were used on ceramic pots. By mixing crushed quartz with calcite (calcium carbonate) from limestone, a solution is produced which can be fired into […]

Suction pump to transistor

In the late 1500s and early 1600s the newfound use of glass for windows and continuing expansion of metallurgy was requiring ever increasing amounts of timber for fuel. As nearby forests were diminished, demands for the mining of coal and coke increased. New uses for metals of all kinds added to the need for mining. […]

1608 – Torricelli – bio

Evangelista Torricelli was born in Italy in 1608 and was a mathematician, astronomer and physicist, mainly known for inventing the barometer. He advanced Galileo’s work on the trajectory of projectiles and worked on rotating shapes around an axis to create three dimensional figures. This helped him create extensions to Cavalieri’s method of indivisibles. “Torricelli’s theorem” […]

1623 – Pascal – bio

1623 - Pascal - bio

Blaise Pascal was born in 1623 in Clermont, France. He is mostly known as being an outstanding mathematician, but also was a physicist and philosopher. He made significant contributions to the areas of conic sections and projective geometry. Pascal’s triangle is a number matrix in the shape of a triangle with the numbers staggered so […]

1643 – barometer

Galileo knew that pumps had a problem pushing water to an elevation above thirty feet and had theorized that a vacuum might be involved. At the time, the idea of a vacuum was controversial and there was no observational evidence that it could exist. He assigned one of his students, Torricelli to work on this […]
