The oldest and most important treaitse of the post-Christian period on Indian Astronomy that has come down to us is the Surya Siddhanta consisting 14 chapters written in slokas. Alberuni says that Lata was the author of this work. According to the introductory verses Surya the sun-god revealed it to Asura Maya in the city of Romaka.

Empirical reality has been the focus of most scientific studies. But, humans have always been curious about how awareness, consciousness, sub-consciousness, or how the mind works. How are thoughts formed? Am I the mind? Is the brain responsible for consciousness? Are thoughts consciousness? Are there sub-conscious thoughts? Is the observable universe the truth? Is there a truth beyond reality? What is difference between a living being and a non-living being? What is the soul? If it is not about consciousness, the next curiosity has been about space, time and matter. Is space finite or infinite? If space is expanding, where is it expanding into? What is time? Are there extra dimensions to space? Is time the 4th dimension? How many dimensions are present? How does space and time relate to consciousness? If consciousness was not present, would there be space and time? Is this whole universe just a thought? Is there a consolidated thought that ties all living beings together? Surya Siddanta, the ancient sanskrit literature, when translated in the context of "emergence of reality", answers just these questions. The concepts presented are surprisingly different and highly thought provoking, making us question our own science which we hold as undisputable. The Surya Siddanta describes the various steps involved the formation of reality, as it traverses from that incomprehensible, unmanifested qualityless truth to the formation of an Individual. This book explores the ideas, the principles and concepts presented in Surya Siddanta, and explains the steps presented with equivalent examples as seen in technologies created by us.

Terrorist's Creed casts a penetrating beam of empathetic understanding into the disturbing and murky psychological world of fanatical violence, explaining how the fanaticism it demands stems from the profoundly human need to imbue existence with meaning and transcendence.

This radical, profoundly scholarly book explores the purposes and nature of proof in a range of historical settings. It overturns the view that the first mathematical proofs were in Greek geometry and rested on the logical insights of Aristotle by showing how much of that view is an artefact of nineteenth-century historical scholarship. It documents the existence of proofs in ancient mathematical writings about numbers and shows that practitioners of mathematics in Mesopotamian, Chinese and Indian cultures knew how to prove the correctness of algorithms, which are much more prominent outside the limited range of surviving classical Greek texts that historians have taken as the paradigm of ancient mathematics. It opens the way to providing the first comprehensive, textually based history of proof.
