Formations of Matter, Light and Sound described with Bernoulli’s principle

AIP Conference Proceedings, 2007
Properties of Bernoulli’s principle are investigated. Assuming a velocity field, dynamics of a hurricane are described. In a multi‐scale model, formulas for gravitational red‐shift are recovered, by regarding the flow of light particles as a mixture with a Newtonian gravitating body. For sound in a mixture, a Doppler formula is deduced.

Johann Bernoulli's brachistochrone solution using Fermat's principle of least time

open access: closed, 1999
Johann Bernoulli's brachistochrone problem is now three hundred years old. Bernoulli's solution to the problem he had proposed used the optical analogy of Fermat's least-time principle. In this analogy a light ray travels between two points in a vertical
