This Indian Solved Calculus BEFORE Newton. The Erased History of Madhava and Kerala School of Maths & Astronomy

Three hundred years before Newton, a Kerala scholar was already writing infinite series for sine and cosine. Why has almost no one heard his name?

In fourteenth-century Kerala, Madhava calculated pi to eleven decimal places using nothing but a palm leaf and a metal stylus, coming within four digits of the precision NASA later used to navigate spacecraft. His methods, refined over two centuries by scholars like Jyeshtadeva and Nilakantha Somayaji, anticipated core ideas of calculus and even proposed a partial heliocentric model decades before Copernicus.

Today, that same mathematics quietly underpins the sine-wave processing inside your smartphone and the numerical methods taught at IIT Madras and MIT. This episode traces how a tradition this advanced was studied by the British in 1835, then left out of the textbooks anyway.
