Pump ProblemIn 1630, Giovanni Baliani, a physicist and experimenter, queried Galileo why syphon pumps stopped working at a pumping height of 30ft?

In 1632, Galileo, in
his Dialogue Concerning the Two New Sciences the adjacent (middle)
theoretical device to measure the vacuum?
Vacuum Measuring Device
Berti Water Column Experiment
In 1639, Gasparo Berti, having read Galileo’s Dialogue Concerning the Two New Sciences, decided to build a device to test Galileo’s water column rope breaking model?
Torricelli Mercury Column ExperimentIn 1643, Evangelista Torricelli, working with Vincenzo Viviani, both students of Galileo, repeated the Berti experiment, using mercury instead of water?
Pascal | Atmospheric Pressure ExperimentIn 1648, Blaise Pascal had his brother-in-law carry a mercury barometer to the top of Puy de Dome, recording the changes in mercury column height along the way, finding that the column height fell during the ascent:
Newton | ForceIn 1686, Isaac Newton established the gravitational force of attraction between two bodies, varies as the product of their masses and the inverse radius of separation squared:
Bernoulli | Pressure
wherein m1 one is the mass of the earth, and m2 is the mass of either the gas molecule (N2 or O2) or mercury molecule (Hg).
In 1738, Daniel Bernoulliestablished that pressure is force per unit area, measured at the surface of interaction:
Warntz | Social ForceIn 1950s, William Warntz, of the Princeton social physics school, established that the force Fi of attraction between two social bodies, varies as the product of their masses and the inverse distance d of separation squared:
wherein P1 and P2 are populations of given cities, e.g. New York and Chicago, and k is a social gravitation constant.

Social Pressure | Teen / High SchoolFermi’s 1938 method of quantifying pressure-volume work for “irregular
shapes”: surface element dσ (d-sigma) and the displacement element dn:
Social Barometer | PredictionPrediction: in Big Cities, the social vacuum, or ‘Torricelli’ space, should be smaller (social mercury height more); in Small Cities, the social vacuum should be larger (social mercury height less).
