Deciphering Indus Script- Professor Rajesh Rao's journey

Professor Rajesh Rao have done extensive research to decipher Indus Script.
His research paper was published in IEEE with subject
"Probabilistic methods for analyzing sequences are providing new insights into the 4,000-year-old undeciphered script of the Indus civilization".

He also rebutted claims of Steve Farmer, Richard Sproat, and Michael Witzel that "the Indus valley civilization was illiterate and that Indus writing was a collection of political or religious symbols".

His paper to debunk above thesis from Witzel can be read here.

Following is his excellent talk on the research at TED.

The great mathematician Aryabhata

http://www.archive.org/details/The_Aryabhatiya_of_Aryabhata_Clark_1930 The Aryabhatiya of Aryabhata (CE 476 to 500) is one of the most important texts in the history of Indian mathematics and astronomy. He composed this work at the age of 23. Here are some of his noted achievements that are found in Aryabhatiya: 1. Aryabhata asserted that the Moon and planets shine by reflected sunlight and that the orbits of the planets are ellipses. 2. He also correctly explained the causes of eclipses of the Sun and the Moon. 3. His value for the length of the sidereal year at 365 days 6 hours 12 minutes 30 seconds is only 3 minutes 20 seconds longer than the true value of 365 days 6 hours 9 minutes 10 seconds. 4. He estimated the value of 'Pi' as : "Add four to one hundred, multiply by eight and then add sixty-two thousand. The result is approximately the circumference of a circle of diameter twenty thousand. By this rule the relation of the circumference to diameter is given." In...

Vedic Mathematics : Shulba Sutras

From research paper "Applied Geometry of the Sulba Sutras" by John F. Price The Sulba Sutras, part of the Vedic literature of India,describe many geometrical properties and constructions such as the classical relationship           a 2 +b 2 =c 2 between the sides of a right-angle triangle and arithmetical formulas such as calculating the square root of two accurate to five decimal places. Although this article presents some of these constructions,its main purpose is to show how to consider each of the main Sulba SDtras as a finely crafted, integrated manual for the construction of citis or ceremonial platforms. Certain key words, however, suggest that the applications go far beyond this. Paper "Square Roots in the Sulbasutra" by  David W. Henderson can be read here .

Adi Shankara : Life and Mission of a great revivalist and pillars of Advaita Vedanta

Image
Sri Adi Shankaracharya (CE 788—820), one of the pillars of Advaita Vedanta (non-dualism), continues to inspire intellectuals and sages, though he lived more than a thousand years ago. The four Mathas that he founded in Sringeri (Karnataka), Dwaraka (Gujarat), Puri (Orissa) and Jyotirmath (Uttarakhand) in India are eminent centers of knowledge and authority in Hindu tradition. Some of the most important of Shankaracharya's works are his commentaries on the Brahmasutras - Brahmasutrabhashya - considered the core of Shankara's perspective on Advaita, and Bhaja Govindam written in praise of Govinda or Lord Krishna - a Sanskrit devotional poem that forms the center of the Bhakti movement and also epitomizes his Advaita Vedanta philosophy. In addition, Vivekachudamani, B...
