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!
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
It’s a special number. It shows up everywhere. In chemistry, physics, math, whether you’re talking circles or cycles or anything to do with a curve, you’re going to find pi in there somewhere. Pi is irrational, which means that you can’t calculate pi by dividing an integer by any other integer. Continue reading Pi Day | Enjoy & Celebrate Mathematics
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. Continue reading The World’s Oldest Zero!
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. Continue reading He knew how the stars will die | Chandrasekhar
When we were children, the summer holidays seemed to last forever, and the wait between Durga Puja-Diwali festivals felt like an eternity. So why is that when we get older, the time just seems to zip by, with weeks, months and entire seasons disappearing from a blurred calendar at dizzying speed? Continue reading Time Seems to Go by Faster as We Get Older
