Not illustrated. 1906 edition. Excerpt: ... other? The pressure, temperature, and vapor tension at a station are in fact the results of a very complex circulation which passes over a station as the effect of conflicting currents flowing from the polar and the tropical zones, due to the incessant struggle of the elements toward equilibrium in this thermodynamic medium. We have to deal with no single system of independent events, as the waves in a normal energy spectrum, or the molecular velocities in a gas of given energy, but there are many series of interdependent events inextricably interwoven. It is seldom that the meteorologist has a pure series of events to work with, as the astronomer or the physicist has in many of his observations, and that is why the meteorologist has a peculiarly diflicult task, and why it is late on the field as a perfect science. Nevertheless, these problems are most fascinating, and they will probably in the future engage more of the attention of astrophysicists and of mathematical physicists, because they 32--Bull. Phil. Soc., Wash., Vol. 14. I afford concrete examples of the most profound questions in theoretical physics. THE THEORY OF LEAST SQUARES IN SOLAR PHYSICS. When we come to solar physics the case is even more troublesome. There we have at an enormous distance from us an immense mass of seething matter at very high temperatures. From observations on the surface phenomena of the sun, the inference is inevitable that all the intractable conditions which on the earth render it diflicut to apply the probability theorem are there multiplied in their complexity. The recurrences of the spots, faculae, and prominences on the surface of the sun are simply resulting products of very complex processes going on in the interior, and in the circulation..show more
