The Dawn of a New Technological Era: Riding Four Exponentials at Once
Read more: The Dawn of a New Technological Era: Riding Four Exponentials at OnceIt’s an incredibly exciting time to be someone who works across different fields of science and tech. With all the doom and gloom, we hear about R&D policy and geopolitical uncertainties, it’s easy to get pessimistic. These are the times when one needs to put on a dreamer’s hat and there’s actually immense cause for…

Simple Introduction to the Geometry of Learning
Read more: Simple Introduction to the Geometry of LearningEveryone learns differently. For me, the most intuitive way to grasp complex ideas has always been through geometry and visualization. This is how I learned machine learning techniques like LLE (Local Linear Embedding) and ISOMAP when I was first introduced to them in 2007. Long before that I was thinking about the reduction of big…

Ideas Are Funny Little Things
Read more: Ideas Are Funny Little Things“Ideas are funny little things. They won’t work unless we do.” This is the quote on a plaque in my living room. It’s the only heirloom I valued enough to bring from my childhood home in India. As you can see from the image, the plaque has gained round edges and chips from all the…

Heterogeneities, tyranny of scales, and curse of dimensionality
Read more: Heterogeneities, tyranny of scales, and curse of dimensionalityIn most complex physical systems (and to some extent others like financial markets), competing non-linear forces lead to instabilities and organized large scale structures. The overall dynamics are controlled by the large scale structures to a great extent but those large structures cannot be accessed directly as they are the result of the small scale…

We’ve Been Solving the Wrong Problem – introducing The Shunya Toilet
Read more: We’ve Been Solving the Wrong Problem – introducing The Shunya ToiletSome problems aren’t just problems; they’re personal. For me, that problem crystallized at a public event in Knoxville, Tennessee. I took my two-year-old daughter to a portable potty, and the moment I opened the door, she recoiled. That look of pure disgust on her face was a gut punch. It sent me right back to…

Where was I on the exponential computing journey?
Read more: Where was I on the exponential computing journey?I just got a 90-teraflop (AMD Ryzen AI 7 with NPU and Nvidia 5070 RTX GPU) laptop for $1200, and that made me reflect on the history of computing. This is like having a supercomputer worth tens of millions of dollars and consuming ~10 MW of power in 2005, right on my kitchen desk and…

Dawn of a golden era for computational science!
Read more: Dawn of a golden era for computational science!For those of you who are not familiar with computational science – it is the discipline at the intersection of domain science, computer science, applied mathematics, and engineering. In a nutshell, it is the link between everything you touch and feel (natural and human-made) and rapidly growing computing. The most challenging science and technology problems…

Happy Father’s Day 2025
Read more: Happy Father’s Day 2025Happy Father’s Day! Especially to the scientists who are not getting much love these days and enduring a lot of uncertainty. I spent my time watching Cosmic Dawn by NASA (https://youtu.be/uSMGENDH_QI?si=1SVttqIqxP6oat50) with my kids – the fabulous story about James Webb Space Telescope (JWST). We don’t do enough in science to publicize successes. JWST is…
