Item Mach’s principle(2011-04-10) Narlikar, J. V.The underlying idea in Mach's principle is that the origin of inertia or mass of a particle is a dynamical quantity determined by the environment, in particular the rest of the matter in the universe. In this article, we discuss the role of this idea in the Brans {Dicke theory of gravitation and the Hoyle {Narlikar cosmology.Item Cosmology and the origin of nuclei(2010-04-06) Narlikar, J. V.The problem of explaining the origin of all the chemical elements found in the universe is a central problem in astrophysics. In the 1940s Fred Hoyle suggested that they were cooked inside stars, starting with nucleosynthesis of neutrons and protons. In the same decade George Gamow argued that in a hot big bang universe in the first few minutes, the ambient conditions were suitable for formation of nuclei. This paper will review the progress of both these ideas and show that a reasonable compromise between these ideas can be found today.Item Fred Hoyle’s universe(Indian Academy of Sciences, 2010-10-25) Narlikar, J. V.This article recalls some of the seminal contributions to astronomy made by Fred Hoyle. His ideas were thought to be unrealistic at the time they were proposed, but have now been assimilated into mainstream science. A general comment that emerges from such examples is that highly creative individuals who are far ahead of their times do not get the recognition they deserve once their ideas are rediscovered and accepted as standard: for, by the time this hap-pens, they and their contributions are forgotten.Item Einstein and cosmology(Oxford University Press, 2010-04-14) Narlikar, J. V.
