1745 – Capacitor/Layden Jar
1745 – Capacitor/Layden Jar – Pieter van Musschenbroek
Pieter van Musschenbroek and his assistant, while trying to get sparks using glass with in it water, a wire and a charged glass tube. His assistant held the jar in his left and with the wire in the water and the other end of the wire in the charged tube.
When he touch the wire there was a large spark and he felt a in his body.
Later they would add a stopper and wire with a ball. This became know as the layden jar, named after the university of Leyden where the experiment was done.
There was another person Von Kleist who may have done the experiment first, but Pieter van Musschenbroek account was clear and repeated by other.
Pieter van Musschenbroek was also the first to use the term physics.

1729 – Conduction
1729 – Conduction – Stephen Gray
Stephen Grey was a dyer by profession, but had interests in astronomy and natural sciences. His education was mostly self educated. We he retiremented he experimented with static electricity. In one experiment he used a glass tube which he kept the ends closed with cork, to keep the tube clean.
He noticed that when he rubbed the glass tube the cork, attracted items. He put a stick into the cork and was able to extend attraction. He began to do experiments to see how far he could extend the effects.
This was the beginning of experiments with conduction, the ability to move electrons through materials.

1709 – Glowing discovery

1709 – Glowing discovery – Francis Hauksbee Francis Hauksbee, also known as Francis Hauksbee the elder, experimented with mercury after hearding of the account that the french astronomer Jean Picard in 1675 had observered a faint glow while caring a mecury barometer.
He discovered that mercery in a glass cantainer exposed to static electricitity can glow bright enough to read by. This is called electroluminescence.
Francis Hauksbee make a modified static electric generator like Otto von Guericke’s, which had mercury in the glass ball with a partial vacuum. When it was spun and a hand placed on it, it gave off light.

1660 – Static electric generator
1660 – Static electric generator – Otto von Guericke
Otto von Guericke invented the first static electric generator. It was a sulfur ball on a rod that can be hand cranked and rubbed with a object to generate static electricity. He heard crackling and felt the hairs sand on end. Soon other in Europe were copying it and making improvements.
