Small Amplitude Waves: Applications,Around 1902, Sir James Jeans investigated the stability of a self-gravitating fluid. This calculation considers the fate of small-amplitude waves (‘sound waves’) in a fluid which generates its own gravity.

Selected Problems,Aims of this exercise: [1] learning to work with some of the fundamental equations of fluid mechanics in terms of vector components and [2] exploiting the mathematical properties (“symmetries”) such as incompressibility and the rotation-free property (i.e. no swirls in the fluid).

Introduction,bic meter, and even the beautifully colored emission nebulae that grace the pages of many popular astronomy books contain gas with a number density (the number of atoms per unit volume) that is much less than the lowest density that can be achieved by the best vacuum pump in a laboratory on Earth.
