Notes of Nagesh

Chuppala Nagesh Bhushan For more than two thousand years, a single mathematical text has survived wars, the burning of libraries, the collapse of empires, and the complete reinvention of mathematics itself. Euclid's Elements , composed in Alexandria around 300 BCE, remains one of the most reprinted, translated, and studied books in human history — outpaced in editions, by some estimates, only by the Bible. Yet today, no working mathematician needs the Elements  (  https://farside.ph.utexas.edu/Books/Euclid/Elements.pdf  ) to learn geometry. Modern textbooks present the same theorems more efficiently, with better notation and clearer diagrams. So why does this ancient text still command a devoted readership of students, scientists, and curious minds nearly twenty-four centuries after it was written? The answer has little to do with geometry itself, and everything to do with a method. The Masterclass in Axiomatic-Deductive Reasoning The Elements is not, at its heart,...

Chuppala NAgesh Bhushan Inspired by Stephen Petro's lecture   A 2,300-year-old textbook on triangles turns out to be one of history's best courses in clear thinking IT IS a strange fact of intellectual history that one of the most reliable ways to sharpen the mind has nothing to do with case studies, leadership retreats or business-school frameworks. It is a geometry book. Written around 300BC by a mathematician in Alexandria, Euclid's "Elements" set out to prove facts about points, lines and triangles. But across the centuries it has quietly done something else: it has taught some of history's sharpest minds how to think. Four examples make the case. Abraham Lincoln came to Euclid out of professional frustration. Self-taught and largely unschooled, he found that he kept losing arguments he ought to have won—not because his facts were wrong, but because he could not properly demonstrate his claims. So he retreated to his father's farm and did not re...

  The Missing Discipline: Why Indian Universities Must Teach Intelligence Studies India trains more engineers than any other country on earth. It produces civil servants through one of the most competitive examinations in human history. It has, in the IITs and IIMs, built institutions that rival anything the West has to offer. And yet, in a nation perpetually negotiating a contested border with China, absorbing cross-border terrorism from Pakistan, managing insurgencies in its northeast, and increasingly exposed on a digital frontier that did not exist a generation ago, there is no serious, sustained, academically rigorous discipline of intelligence studies anywhere in the Indian university system. This is not a small oversight. It is a structural gap with consequences that show up, with grim regularity, in commission reports written after the damage is done. A Discipline That Exists Everywhere Except Here Walk into King's College London and you will find the Department of ...

  Chuppala Nagesh Bhushan How one bureaucrat's improvisations built Cyberabad, and why he now wants to do it all again in the villages HYDERABAD IN 1990 a government official arrived in Hyderabad with a freshly signed posting, a four-floor lease and very little else. The building he had leased, a new block called Maitrivanam in the suburb of Ameerpet, had no tenants. The state he had moved to had no software-exporting firms. The city had no internet connection of any kind. J.A. Chowdary, then a regional director for India's Software Technology Parks of India (STPI) scheme, had arrived from Bengaluru, where he had spent the previous five years wiring that city's young software industry to the rest of the world via a satellite dish, beamed in the earliest days through a relay in Colombo. He assumed, not unreasonably, that Hyderabad would need the same thing. It did not yet need anything, having no software industry to connect. That this chicken-and-egg problem—no comp...

Chuppala Nagesh Bhushan An appeal to reason in an age of godmen, gullibility, and engineered ignorance   The Constitution's Forgotten Promise Article 51A(h) of the Indian Constitution places a remarkable obligation on every citizen: to develop the scientific temper, humanism, and the spirit of inquiry and reform. This is not a guideline. It is a fundamental duty — as binding in its moral weight as any right we jealously claim. And yet, in 2026, India is watching that promise drown in a flood of sacred ash, miracle water, and prime-time astrology. We are a nation that sends spacecraft to the Moon and Mars. We produce world-class mathematicians, biologists, and engineers. And simultaneously, we are a nation where stadium-sized crowds prostrate before men who claim to materialise gold from thin air, cure cancer with cow urine, and commune directly with the divine — for a fee. This is not a contradiction we can afford to be proud of. It is a crisis.   The Godman I...
