    July 2, 2015 - By ckr

    Became an honorary member of the the Institute of Complex Thought at the University Ricardo Palma. Good to know that they want to try the 5-day course on calculus.

    Decolonisation in South America-1

    July 2, 2015 - By ckr

    A few years ago, when a friend, Jorge Ishizawa from Lima, asked for a copy of my book Cultural Foundations of Mathematics, I wondered what he would do with it. (I sent it, but it bounced back.) On a recent visit to Peru, I had a conversation with people at…

    MIT Talk: Calculus the real story

    May 19, 2015 - By ckr

    The abstract of my talk at MIT differs from my presentation, posted at http://ckraju.net/papers/presentations/MIT.pdf. The point I made in the talk was that MIT teaches calculus and trigonometry wrongly. This is just because Europeans failed to understand the mathematics they imported from India. For example, the very words “trigonometry”, “zero”, “surd”,…

    Raju’s paradox: all formal mathematicians are fools

    May 12, 2015 - By ckr

    For almost two decades now, I have been pointing out that formal mathematics (and much Western philosophy) is based on the false belief that proof based on two valued logic (“deduction”) is “superior” to empirical proof (“induction”). This belief is NOT universal (e.g. Indian mathematicians used empirical proofs, e.g. Buddhists…

    Teach religiously neutral math

    October 24, 2014 - By ckr

    My article published today in The Hindu, was heavily abbreviated. The more detailed original article in about 1200 words is easier to understand. The petition to teach religiously neutral math, and related material is already on this blog. A draft of a more detailed paper on “Eternity and Infinity” delineating…

    Nothing Vedic in Vedic maths: response to comments

    September 6, 2014 - By ckr

    My article in The Hindu, 3 Sep 2014, received 214 comments and 4.3k Facebook Likes. Here are my responses. (A separate response in Hindi to Dinanath Batra’s associate’s comments on my Jansatta article in Hindi of 10 Aug 2014 is given below.) Abuse. Some people have turned abusive and chanted abuses like mantras! Funnily,…

    Infinity, math, physics, and metaphysics

    June 14, 2013 - By ckr

    Can physics be done without infinity as taught in math (real analysis) today? Someone demanded an explanation in an email sent to my son.  (I guess the Raju family has the same problem as the Bernoulli family in Europe!  🙂 .) Ordinarily, I would not have responded, for people ought…

    Yoga, mathematics, and ganita

    June 9, 2013 - By ckr

    Yoga has been accused in the US of having religious roots, hence unfit to be taught in public schools, and there is  court case going on to that effect. The obvious solution is to teach yoga only for its practical value in public schools. But mathematics too has exactly the…
