About the Author

B.G. Sidharth got his B.Sc. (Mathematics Honors), M.Sc. and PhD from Calcutta University. After working for several years in Quantum Scattering, Dr. Sidharth’s work entered on the fundamental problems facing Physics today. His 1997 papers, contrary to the ruling paradigm, predicted a dark energy driven accelerating Universe with a small cosmological constant. Remarkably, this was confirmed in 1998. His work deals with fuzzy spacetime and the unification of interactions and similar problems within this context. Besides a large number of research publications in international journals, Dr. Sidharth also authored and edited a number of books. In addition he has lectured widely in the United States, Canada, Europe and other places.

B.G. Sidharth is the founder-director of the B.M. Birla Science Centre, Hyderabad, India, and its constituent, the International Institute for Applicable Mathematics and Information Sciences, Hyderabad, and Udine, Italy. He was associated with the International Center for Theoretical Physics, Trieste, Italy, for many years having been a Senior Associate. Dr. Sidharth is on the Editorial / Advisory boards of international journals, institutes and award committees. Last but not least he played host to many Nobel Laureates and other physicists of World importance.
