Mathematical Astronomy Morsels IV by Jean Meeus
In his Preface to Mathematical Morsels III Jean Meeus writes: We are living in a period of important astrophysical and cosmological research. Many astronomical journals and scientific books deal with subjects such as birth and evolution of stars, black holes, dark matter, gamma-ray bursts, supernova remnants or collisions between galaxies. Of course this is important matter, but one almost seems to have forgotten the `old’ astronomy, the classical, mathematical science of the sky. And yet, without this fundamental astronomy modern research on the universe new would never have been possible.
And to this Roger Sinnott responded “In his Preface the author hints that some readers might accuse him of practicing “old” astronomy. Don’t let that fool you. The problems he tackles would have fascinated astronomers of the early 20 th and prior centuries, but those poor souls faced a brick wall of computational difficulty. They had to work out all their answers laboriously, with a pencil and paper. Freed, from that limitation, the author uses today’s computers to address each topic with a rigor and finesse beyond the wildest dreams of any old-time practitioner.
