Discoveries in Modern Physics,especially the discoveries from the beginning of 20th Century,are making it more and more evident that many conclusions of Modern Physics are exactly the conclusions of Vedanta philosophy enshrined in the Upanishads and countless other Vedantic texts. This small book is a very humble attempt to project how some of the conclusions of modern physics converge with the very words and ideas of the ancient Vedanta,and it's modern interpretations given by Swami vivekananda. Review John A.Wheeler in his letter to the Author has the following words to say. "I like to think that someone will trace out how the deepest thinking of India made it's way to Greece and from there to the philosophy of our times. Your wonderful analysis of the great questions inspires us all in the great search that follows the spirit of the Upanishads,of Plato's dialogue and modern science." --John A.Wheeler.lassical physics and the Enlightenment period had as it s aim nothing short of conquering the great mysteries of the universe through human reason.Newtonian models revealed a world of order that,if studied closely,could be represented by words,numbers,formulae and ideas.Twentieth century science,on the other hand,painted a different picture:the universe is fundamentally non-linear and does not lend itself to ready classical descriptions.Relativity,the uncertainty principle,quantum mechanics and chaos theory,each in their turn,took a bite out of former simplistic Euclidean views of an ordered universe.Yet,what in a former era might have been feared as a crisis in science is proving to be a variable revolution the golden age of physics filled with wonder and excitement,where all that was once held dear and indispenable is being renegotiated and deepened.As contemporary (quantum) theories grope for a language to describe what seems to defy description,there is an increasing reliance on conceptual levers and metaphor systems from ancient (Eastern) religions,among them Vedas. In this his doctoral dissertation,the author attempts to correlate the ancient wisdom of the Upanishads (as contained in the thought of Adi Sankara) with the contemporary physics and cosmology of Einstein,Heisenberg,Dirac and Schrodinger as well as that of other notables like Hermann Weyl,Arthur Eddinton,Neihl Bohr,Max Born and James Jeans.The author has an adequate grasp of his subject and raises challenging questions relevant for both the student of Vedanta as for those of contemporary physics.While his scope is vast,his treatment is thorough and erudite.He lays out a buffet of challenging ideas and new ways to rethink,on the one hand Vedanta,vis-à-vis contempory science and,on the other,the revolution in physics,vis-à-vis the ancient wisdom language of Vedanta and the classics of Adi Sankara.He elucidates a number of fascinating subjects which have intrigued scientists,philosophers and spiritual seekers over the centuries.Some examples:the role of the observer,which is the scientific experession of consciousness,is mapped into Vedanta s witness for comparision:Einstein s Relativity theory is discussed as a physical version of Sankara s superimposition (adhyasa),the field model of reality in science is articulated in terms of Brahman s potential to manifest names and forms.In the author s skillful hands,a number of the weirdities and oddities of quantum theory and observation are able to find conceptual grounding in classical Vedic language.Systems theory,causality,the quest for a unified field,scientific epistemology,cognition,toward a theory of perception,paradox,and indeterminancy are just a few examples of the concerns raised in this very comprehensive text.The author s reflections are engagingly fresh and exciting. --M.S.Balasubramanian/Mountain path/Ramanasramam About the Author Swami Jitatmananda is a Monk of the Ramakrishna Order and has held many important assignments besides participating in a numb
