Stability of the Solar System is unlikely any of the planets will collide with each other or be ejected from the system in the next few billion years, and the Earth's orbit will be relatively stable. Since Newton's law of gravitation (1687), mathematicians and astronomers (such as Laplace, Lagrange, Gauss, Poincaré, Kolmogorov, Vladimir Arnold and Jürgen Moser) have searched for evidence for the stability of the planetary motions, and this quest led to many mathematical developments, and several successive 'proofs' of stability of the Solar System. The orbits of the planets are open to long-term variations. Modeling the Solar System is a case of the
Gustav Holst the lower strings had to be replaced by a tuba to obtain an effective bass sound. With an anonymous string orchestra Holst recorded the "St Paul's Suite" and "Country Song" in 1925. Columbia's main rival, HMV, issued recordings of some of the same repertoire, with an unnamed orchestra conducted by Albert Coates. When electrical recording came in, with dramatically improved recording quality, Holst and the LSO re-recorded "The Planets" for Columbia in 1926. In the early LP era little of Holst's music was available on disc. Only six of his works are listed in the 1955 issue of "The Record
