kerala school of math and the origins of calculus: was it transmitted to europe from here?

this paper is available on the web for download as a word document. an excerpt is below.

i also have another paper (from peer-reviewed journal 'race and class', "eurocentrism in the history of mathematics: the case of the kerala school") by the same authors alameida and george joseph at exeter/manchester univs, uk. btw george joseph spoke recently in trivandrum, and his book "the crest of the peacock" is well-thought-of. 

there is also the research by ian pierce at st. andrews univ in scotland.

in the context of the 'indian science congress' expressing ignorance about ancient indian science, it's worth pointing out that a lot of modern mathematics and astronomy originated in kerala!

Abstract: Mathematical techniques of great importance, involving elements of the calculus, were developed between the 14th and 16th centuries in Kerala, India. In this period Kerala was in continuous contact with the outside world, with China to the East and with Arabia to the West. Also after the pioneering voyage of Vasco da Gama in 1499, there was a direct conduit to Europe. The current state of the literature implies that, despite these communication routes, the Keralese calculus lay confined to Kerala. The paper is based on the findings of an ongoing research project, which examines the epistemology of the calculus of the Kerala school and its conjectured transmission to Europe. 

 

 

1. Introduction.

According to the literature the general methods of the calculus were invented independently by Newton and Leibniz in the late 17th century[1] after exploiting the works of European pioneers such as Fermat, Roberval, Taylor, Gregory, Pascal, and Bernoulli[2] in the preceding half century. However, what appears to be less well known is that the fundamental elements of the calculus including numerical integration methods and infinite series derivations for p and for trigonometric functions such as   sin x, cos x and tan-1 x (the so-called Gregory series) had already been discovered over 250 years earlier in Kerala. These developments first occurred in the works of the Kerala mathematician Madhava and were subsequently elaborated on by his followers Nilakantha Somayaji, Jyesthadeva, Sankara Variyar and others between the 14th and 16th centuries [3]. In the latter half of the 20th century there has been some acknowledgement of these facts outside India. There are several modern European histories of mathematics[4] which acknowledge the work of the Kerala school. However it needs to be pointed out that this acknowledgement is not necessarily universal. For example, in the recent past a paper by Fiegenbaum on the history of the calculus makes no acknowledgement of the work of the Kerala school[5].  However, prior to the publication of Fiegenbaum's paper, several renowned publications detailing the Keralese calculus had already appeared in the West[6]. Such a viewpoint may have its origins in the Eurocentrism that was formulated during the period of colonisation by some European nations.
