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 I pondered the spirit of The Mother, my mind went back to the visit we’d taken to the Jantar Mantar in Jaipur — an astronomical observatory built around the time of Newton’s discovery. Surely, a society that had the capacity to develop highly accurate astronomical predictions had the sophistication to develop the machinery for dealing with infinitesimal rates of change.
Newton — or more likely Leibniz — was indeed late to the game by at least 200 years!
Keralan mathematician Nilakantha Somayaji in the 1400s seems to have worked out machinery for dealing with infinitesimal velocity and converging series.
What are those ideas? Langlands has spent his life looking for connections between number theory and real analysis. The featured image is a rendering of an automorphic form, one of the kinds of functions that Langlands has been interested in. As far as I could understand, Beilinson and Drinfeld found ways of connecting this work to modern physics. Maybe a deeper understanding is my goal for 2018. This Quartz article is a good quick read as is this short piece on the fundamental lemma.
Or, you can let the distinguished Dr Langlands explain it himself.
Whether or not you have a liking for numbers, seeing an 81 year old still in the thick of things is infectiously inspiring. Perhaps you’ll allow him to re-acquaint you with Pythagorus?
Yesterday I came across a photo of two gentlemen sitting outside of my old grad-school student lounge. They are Sasha Beilinson and Vladimir Drinfeld, two mathematicians from my alma mater who were awarded this year’s Wolf Prize in Mathematics.
The CS department at the University of Chicago shared space with Mathematics and Statistics in my day, so it was not unusual to encounter mathematicians while having lunch (or a nap) in the lounge. There have been many usefulcollaborations and intersections between these departments.
I have no idea what Sasha or Vladimir do. I tried to understand. I glanced at their ground breaking work, a book called Chiral algebras. They state in the introduction “Chiral algebras have their origin in mathematical physics;” and “Chiral algebras are “quantum” objects.” Ok.
Drinfeld and Beilinson still run the Geometric Langlands Seminar that of course captures the essence of what they care about most. As best I can figure, Langlands,himself a 1996 Wolf prize recipient, is a mathematician who envisioned building links between algebra and modern physics. Drinfeld and Beilinson have extended that work. Maybe the best explanation of this undertaking is provided by Edward Frenkel.
It is really heartening that discrete geometry and other branches of advanced mathematics can be use to preserve democracy — much in the spirit of the 1964 voting rights act (being signed in the featured image).
Tufts University mathematician Moon Duchin has done a lot of work in this area, leading the effort to train mathematicians to be expert witnesses in gerrymandering cases. Duchin’s Metric Geometry and Gerrymandering Group page has a lot of useful resources.
Consider registering for one of the gerrymandering trainings if you’re a mathematician, statistician, or data scientist based in the Bay Area!
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 US Black History Month thanks to the efforts of student activists of the 1970s.
My partner, Dr Gayatri Sethi, reminds me that the aspiration of marginalized and minoritized peoples to be heard, to enter into equity in whatever place they call home is universal.
Building an equitable mathematics community, or better yet an equitable world, should not be confined to a single month — it is an undertaking that will require continuous and deliberate effort. But it is encouraging and inspiring to see many hopeful signs on a global scale.
Do you know of similar efforts in other countries to encourage the participation of marginalized peoples in science and mathematics? If so, please leave a comment or drop an email!
