Synopsis For this book the relevant question is: What is the universeand why? So far scientists engaged in this field of investigationoccupied themselves seriously with the answering of the whatpart of the question and have just started to answer the whypart, which should normally engage the philosophers. But thelatter, barring a few, are not fully equipped to go deep into thewhat part revealed by the scientists. The gap has to be filledup. The author has taken courage to bring the what and whyparts in one comprehensive volume, and try to answer both.In fact modern science and philosophy are perhaps talkingabout the same thing but in different languages. The attemptto bridge the language gap is what is most important.Sri Manoranjan Basu, the author of this profound work wasnot only a scholar of great attainments but also a researcherand sadhaka of no mean stature.
