Remembrance for Poincaré

If you have read Cixin Liu’s The Three Body Problem, the name Henri Poincaré might ring a bell. Poincaré was an early twentieth century mathematical master. One of his feats was an analysis of how three masses in mutual orbit behave. This analysis provides the foundation for chaos theory. In Liu’s science fiction book, the […]

Happy 1.1919 day!

Today is January 19, 2019, 1/19/19! The number 1.1919 can be expressed as the fraction and the repeated fraction is . Such a rational day! The number 11919 is itself composite, expressible in terms of the primes 3, 29, and 137. Let’s dive into 11919’s 19 side! The featured image is a 19-sided star, a […]

Calculus and The Mother

Last weekend we spent a beautiful afternoon with cousins at the Sri Aurobindo Ashram in Delhi.  There was a lecture going on about the divine inspiration of Calculus — a meditation on how both Newton and Leibniz came to discoveries of infinite series and limits that led to the starting point for advanced maths. As […]

A good year for Robert Langlands

I just saw that Robert Langlands has won this year’s Abel Prize in mathematics. A month back I had noted that two University of Chicago mathematicians –Sasha Beilinson and Vladimir Drinfeld — had received the Wolf prize for work that builds upon Langlands’ ideas. What are those ideas? Langlands has spent his life looking for connections […]

The geometrical beauty of Doha

As we passed through Doha on the way to Gaborone, I was amazed by the architectural beauty of so many Islamic inspired structures. It was truly a feast for the eyes and mind. Though we did not have time to visit many of the older architectural treasures, I discovered that a lot of the buildings […]

Mathematicians, rock the vote!

Can the resistance inspire a new generation of mathematicians? Samuel Hansen thinks so. In his recent post on The Aperiodical, he describes how the recent avalanche of math-informed court decisions on gerrymandering in Pennsylvania and elsewhere are putting mathematics in the spotlight. It is really heartening that discrete geometry and other branches of advanced mathematics can be use […]

Black history month is Black mathematicians month — in the UK

In the US, the African American scholar (and February 1st Google doodle subject) Carter G Woodson began working in 1926 to establish “Negro History Week“, for in Woodson’s day the contributions of Black people were  “overlooked, ignored, and even suppressed by the writers of history textbooks and the teachers who use them.” Woodson’s Negro History week evolved into today’s […]
