Indian calendar: scientific aspects
關於這本電子書
This book explains how the Indian calendar provides a superior and scientific alternative, on which children can learn their जन्मतिथि, and why तिथि ≠ day. Children will also learn how to determine the dates of Indian festivals such as Holi and Diwali, puzzling since moveable on the Christian calendar. And perhaps stand up and question why the dates of the two secular Indian festivals are defined only on the Christian calendar.
Indian astronomy, since ancient times, was scientific, and this book focuses on those scientific aspects, also explaining how science was missing in Graeco-Roman and Western tradition until the 16th c. Ever since the Vedanga Jyotish, the word jyotish meant scientific timekeeping, through astronomy, though the word jyotish is today confounded with phalit jyotish or astrology.
A season missing on the Gregorian calendar is the rainy season vitally important for Indian economy, culture, and for the entire reproductive cycle on the subcontinent.

關於作者
Professor C. K. Raju holds a BSc (Hons), degree in physics, an MSc in mathematics and a PhD from the Indian Statistical Institute. He has long been a Professor in departments of mathematics and computer science. He played a key role in the C-DAC team which built the first Indian supercomputer Param. He received the TGA gold-medal in Hungary in 2010 for pointing out and correcting a mistake made by Einstein.
He has authored two books on “time”: Time: Towards a Consistent Theory (Kluwer Academic, Dordrecht, 1994) and the Eleven Pictures of Time (Sage, 2003). In Cultural Foundations of Mathematics (Pearson Longman, 2007) he explained the theft of calculus from India and why Newton etc. failed to fully understand the stolen calculus, so that its current teaching is defective. His book on Rajju Ganita for school children explains what is wrong with the current teaching of geometry in schools, because of the desire to promote the myth of Euclid, which lacks evidence as pointed out in his book on Euclid and Jesus (Multiversity, Penang, 2012).
His books have been highly praised, and his several articles have also drawn high praise from both referees and readers. He has lectured on six continents and videos of over 100 talks are available.
