Furthermore, magneto-hydrodynamics is important in discussing the problem of how the central body in a plasma cloud can develop into a sun and system of planets, or in investigations of stability conditions for a plasma consisting of electrons and ions moving at relativistic velocities interacting with cosmic fields.
Prof. Walton's first researches involved theoretical and experimental studies in hydrodynamics and, at the Cavendish
Liquid crystals have been known for over a century and their hydrodynamics, that is, how they flow, were studied as early as the 1920s by Professor Wilhelm Oseen of Uppsala.
Nevertheless, one feels that the hydrodynamics of Formula 1 cars displacing both air and a surface layer of water, is a science which has yet to be fully explored or exploited.
I would probably be one of the last people to disagree with the “universal nature of gravity”, but claiming that it is because the equations, in one particular form, resemble the laws of thermodynamics and hydrodynamics is quite unreasonable.
The universal nature of gravity is also demonstrated by the fact that its basic equations closely resemble the laws of thermodynamics and hydrodynamics.
The Atomic Weapons Establishment at Aldermaston in Berkshire will develop hydrodynamics technology, while its equivalent, the Centre for Nuclear Studies, at Valduc in Burgundy, will do the actual tests.
The magneto-hydrodynamics of jets occurs from the huge heating of material falling onto a black hole.
A wag once commented (and I have quoted here often) that to expect a scientist to understand the philosophy of science is like expecting a fish to understand hydrodynamics.
The details (e.g., depth and wavelength) involve the fluid dynamics of the situation (fluid speed and density, particle aero/hydrodynamics, particle interactions, etc.)
