experior, ergo sum
Welcome to my website! I'm Rishav (ऋषभ), and here I share my tinkerings and research. My work centers on theoretical and applied problems in control systems and estimation theory. I am guided by a sense of wonder at what Eugene Wigner described as the unreasonable effectiveness of mathematics as the language of nature [1]. Beyond research, I am fascinated by the the history of science and technology, especially the evolution of physics and mathematics. I am also an avid tinkerer in electronics and embedded systems, who enjoys the process from breadboard prototyping and PCB design to writing embedded firmware.
I must emphasize that I write as a learner and do not pretend to be a professional in the field. I keep a running list of ideas and problems that I like to study and ponder in my own time. Writing about them gives me a good reason to dive deeper. It also helps me avoid the trap of thinking I understand something when I really don't. Almost every post is first read and approved by my wife, Sriza, before I publish it. She has a sharp eye for catching flaws in my reasoning, which I truly admire and respect.
The preface of [2] made me realize I that share Hayes' itchy pencil
tendency—so posts here may get updated or edited whenever the mood strikes. After all, understanding of a topic grows with time, and past writing sometimes needs a touch-up.
Please feel free to write to me, especially if what I share resonates with your interests—whether as feedback (including constructive criticism or simply pointing out errors) or as suggestions for collaboration.
