Subject: Re: Ancient Math

Let us frankly admit that there is a tendency to exaggerate the achievements of our ancestors. Hindu religious fanatics have gone to extreme lengths to prove the greatness of Vedic Mathematics i.e. the Mathematical knowledge that developed 3 to 4 millennia ago when the Hindu sacred books were written. In fact the author of the 1965 publication on Vedic Math (he pre-deceased the publication by 5 years) had said that he obtained his formulae (called "sutras" in Sanskrit) from the appendix to the Atharva Veda. Searches and researches conducted by scholars have not revealed a single copy of the supposed appendix! Such an appendix does not exist. Modern treatises on Vedic Mathematics contain only about sixteen elementary school level formulae that can merely help quick mental calculations in arithmetic. I had used Trachtenberg’s Basic Speed Math with my children in the sixties. This was published a full decade before the first Vedic Math book came out! Trachtenberg was supposed to have worked out all his formulae mentally in a Nazi concentration camp just to keep his faculties intact and to remain sane in the midst of so many dying or losing their senses. Vedic Mathematicians of today claim that the ancients knew the Pythagoras theorem long before the existence of Pythagoras himself. The fact is that they knew a few Pythagorean triplets – 3,4,5; 6,8,10 etc. Though we must credit them with the discovery of the property in some cases, it is now confirmed that they did not know that the property (that the square on the hypotenuse equals . . . etc.) was universally applicable to all right-angled triangles. Their handicap was that they did not have definitive, logical proof for any of their theories - scientific thinking and ergo, scientific logic, was not part of Indian culture. Only five planets plus the sun and the moon and the stars were known to ancient Indians. Yet they wrote vast treatises on astronomy. There were many geniuses in mediaeval India in spite of the Brahminical religious slant to all knowledge. The word 'veda' itself means knowledge. Indian astrology however had no scientific base and like all religious theories it is based on mere faith. Today, the argument rages in India about the scientific base of Vedic Astrology. The Hindu nationalist government has brought this subject into the ambit of the curricula much to the chagrin of the intelligentsia. The stock of schoolteachers and college professors is so low that they have not risen as one man to object to the introduction of this obscurantist theory into India's modern universities! Topics like Mayan Math, Vedic Math and so on should be of great interest to archaeologists and historians, but I think stress on their importance undermines the value afforded to modern knowledge of Mathematics with all the developments that have resulted from it. - - - Prasan Wilfred
