Galileo looked up at a swinging lamp and counted the time it took to swing back and forth and realized that the time remained constant. This was named the principle of swinging pendulum.

Galileo creates the first type of thermometer: were a bulb of air would push water up or let it fall to measure temerature. This was unreliable but was the prototype to better models later. It sold fairly poorly. Age: 29

Torreicelli wrote a letter to Galileo, showing his support for him and his intrest for Galileo's work. When Galileo went to trial for Heresy, Torricelli quickly changed his intrests from the corpernicus theory.

Galileo was convicted of Heresy and was sentenced to life imprisionment, ut due to poor health, was allowed to be under house arrest

Torrecielli moved into Galileo's house to be an assistant and help with his experiments.

Torricelli built the first barmeter filling a 4 foot long tube with mercury which changed height based off the atmospheric pressure. Age:36

Pascal discovered that the mercury barometer changed it's levels based on atmospheric pressure rather than a vacuum. Age: 25

Von Guerick invents the first vacuum pump using a piston and an air gun cylinder. He used this in many experiments in his study of air pressure. Age:42

Von Guericke had sixteen horses pull at two halves of a copper sphere which they could not pull apart when in the vacuum.

Dalton creates Dalton's Law. The law states that that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases. Age:25
