"There are also anomalous statements in Indian texts whose origin is not understood. Just to mention a few: the correct speed of light, the correct distance to the sun, cosmological cycles that broadly correspond to the numbers accepted currently, the fact that the sun and the moon are approximately 108 times their respective diameters from the earth, the correct number of species on earth (about 8.4 million), and so on. Historians either ignore them or say that they are extraordinary coincidences. We will come to these anomalies later in the essay.

"To return to the history of mainstream science, the discovery of infinite series and calculus by Newton and Leibniz heralded the Scientific Revolution that was to change the world. But new research has shown that over two centuries prior the Kerala School of Mathematics had already developed calculus and some historians suggest that this and advanced astronomical knowledge from Kerala went abroad via the Jesuits and provided the spark for its further development in Europe. Other historians discount this saying that clear proof of the transmission of this knowledge to Europe is lacking."
