    Calculus for social scientists

    May 27, 2012 - By ckr

    Europeans made calculus difficult because they did not understand it. The infinite series of the Indian calculus did not fit their religious idea of mathematics as eternal truth, hence perfect.  (Newton made a mistake in his physics just because he did not understand the calculus, and that physics has only recently been corrected.)…

    Unmugged in Rio

    May 27, 2012 - By ckr

    Was all prepared to by mugged in Rio. So much so that it was almost disappointing not to be! In the background is the “mistical” Christ (Corcovado), who remained mistical with his back turned to the world, even when I went to see from close by!

    Retarded gravity

    May 6, 2012 - By ckr

    Presented this talk at a school at Petropolis, Brazil. Lorentz covariance requires that gravity be velocity dependent. But old physicists can’t get over the 19th c. idea, reiterated by Eddington, that introducing velocity dependence in gravity makes the two-body problem unstable! They never studied functional differential equations, and no physics texts yet mentions my first…

    National year of mathematics and delayed monsoon

    May 6, 2012 - By ckr

    But why a year on the Christian calendar? That calendar embodies the European ignorance of elementary arithmetic and simple fractions (hence their persistent inability to determine Easter correctly until the Gregorian calendar reform of 1582 when they got the length of the year from Indian books). Click the image for the text version.…

    Open source software: a charter of demands

    May 6, 2012 - By ckr

    Strange that governments do not support the use of open source, when it has so many advnatages.  Some news reports below on the press conference by the Consumer Association Penang on 13 April, and a full charter of demands.   More press reports.

    Islam and the Philosophy of Science

    May 5, 2012 - By ckr

    The Pusat Islam organized a talk on Islam and the philosophy of science. (Click the image for the paper. But the paper does not cover the queston of ethics of science, taken up during the talk.)

    New curriculum for history and philosophy of science

    May 5, 2012 - By ckr

    A workshop was held at Al-Bukhari International University to formulate a new curriculum for the history and philosophy of science. Scholars from 3 countries participated. Here is the announcement for the workshop, and an earlier one on the Multiversity site. The issue is part of the decolonisation agenda, but was precipitated when…

    Reimagining science teaching

    May 5, 2012 - By ckr

    To teach science one needs to know the right stories of how science developed. That is one needs a truthful history of science, not the trash history one gets from the West. Strange that all those who talk of teaching students to innovate  can only blindly imitate the syllabus from Western universities!
