Algebra in Arjuna’s Arrows!

Bhaskaracharya, an Indian mathematician and astronomer of the 12th century, is considered the progenitor of Differential Calculus – 500 years before Newton and Leibniz. He is referred as Bhaskara II to avoid confusion with Bhaskara I (of the 7th century CE). He was born near Vijjadavida (Bijapur in modern Karnataka) and lived between 1114-1185 CE. He represented the peaks of mathematical knowledge in the 12th … Continue reading Algebra in Arjuna’s Arrows!

A Case of Knightian Uncertainty | COVID-19

Frank Knight, an economist, formalised a distinction between risk and uncertainty in his 1921 book, Risk, Uncertainty, and Profit. In his classic book, Knight introduced a distinction between measurable uncertainty, which he called “risk,” and “true uncertainty,” which cannot “by any method be reduced to an objective, quantitatively determined probability.” Continue reading A Case of Knightian Uncertainty | COVID-19

The Bakhshali manuscript

The World’s Oldest Zero!

The origin of the symbol zero has long been one of the world’s greatest mathematical mysteries. New carbon dating research commissioned by the University of Oxford’s Bodleian Libraries into the ancient Indian Bakhshali manuscript, held at the Bodleian, has revealed it to be hundreds of years older than initially thought, making it the world’s oldest recorded origin of the zero symbol that we use today.

He knew how the stars will die | Chandrasekhar

Chandrasekhar became famous for his discoveries about the evolution of the stars. His work was vast, and he began early, developing his theory of stars’ evolution before he had even turned 20. Google is changing its logo globally to a doodle of him and the Chandrasekhar Limit. That refers to his calculation that once a star reaches 1.44 times the size of our own sun, it doesn’t form a white dwarf as expected but collapses, eventually becoming a black hole.
