Description
In the late nineteenth and early twentieth centuries, the theoretical and experimental research of Norwegian physicists Carl Bjerknes (1825-1903) and his son Vilhelm (1858-1951) on a fluid-dynamic mechanism for electromagnetic interactions was well-known and discussed in Europe. The Bjerknes, convinced that hydrodynamic sink and source entities could not exist in nature, as were all the scientists involved in the creation of field physics, they resolved to model the interactions between objects with central fields using pulsations of elastic hollow spheres immersed in a liquid. Along with his theoretical studies and predictions, Carl Bjerknes, with the assistance of his son Vilhelm, designed experimental setups that confirmed the predicted effects. Two rubber spheres immersed in water and connected by tubes to hydraulic pumps attracted each other if vibrated in phase, and repelled each other if vibrated in opposition of phase. The forces at play are opposite to electromagnetic forces, where two electrons repel each other and an electron is attracted to a proton. The Norwegians' demonstration devices were displayed, attracting great interest and prizes, at various scientific exhibitions of the time. Vilhelm Bjerknes, before becoming a leading figure in modern meteorology, worked tirelessly, through theoretical writings and family history, to preserve the memory of this branch of field physics research at a time when relativistic and quantum theories were gaining widespread attention from the scientific community. Generalizations of these experiments, and a reevaluation of a forgotten experiment by Robinson in 1881, could give new clues to the true nature of light.
