Complementarity and the world: Niels Bohr’s message in a bottle

by Ashutosh Jogalekar Werner Heisenberg was on a boat with Niels Bohr and a few friends, shortly after he discovered his famous uncertainty principle in 1927. A bedrock of quantum theory, the principle states that one cannot determine both the velocity and the position of particles like electrons with arbitrary accuracy. Heisenberg’s discovery foretold of…

How to think like Albert Einstein

by Ashutosh Jogalekar Considered the epitome of genius, Albert Einstein appears like a wellspring of intellect gushing forth fully formed from the ground, without precedents or process. There was little in his lineage to suggest genius; his parents Hermann and Pauline, while having a pronounced aptitude for mathematics and music, gave no inkling of the…

Kurt Gödel’s Open World

by Ashutosh Jogalekar Two men walking in Princeton, New Jersey on a stuffy day. One shaggy-looking with unkempt hair, avuncular, wearing a hat and suspenders, looking like an old farmer. The other an elfin man, trim, owl-like, also wearing a fedora and a slim white suit, looking like a banker. The elfin man and the…

The ethics of regulating AI: When too much may be bad

It is one of the most famous speeches in favor of freedom of expression. Milton was arguing against a parliamentary ordinance requiring authors to get a license for…

Models of the Mind: A Conversation with Grace Lindsay

by Ashutosh Jogalekar Grace Lindsay is a computational neuroscientist at University College London. She has just published a new book titled “Models of the Mind: How Physics, Engineering and Mathematics Have Shaped Our Understanding of the Brain“. Most books about the brain take either a biological or philosophical approach, but Grace’s book is rather unique…

“How to Avoid a Climate Disaster”: A fun read about a serious topic

by Ashutosh Jogalekar Bill Gates’s book on climate change issues and solutions is exceptionally clear and simply written. Gates has an easy conversational style that makes the book a fun read, and he is clear-eyed about the problem and the solutions. He also stays away from politics, which makes the book a refreshingly apolitical read,…

Does belief in God make you rich?

by Ashutosh Jogalekar Religion has always had an uneasy relationship with money-making. A lot of religions, at least in principle, are about charity and self-improvement. Money does not directly figure in seeking either of these goals. Yet one has to contend with the stark fact that over the last 500 years or so, Europe and…

What John von Neumann really did at Los Alamos

by Ashutosh Jogalekar During a wartime visit to England in early 1943, John von Neumann wrote a letter to his fellow mathematician Oswald Veblen at the Institute for Advanced Study in Princeton, saying: “I think I have learned a great deal of experimental physics here, particularly of the gas dynamical variety, and that I shall…

Analogia: A Conversation with George Dyson

by Ashutosh Jogalekar George Dyson is a historian of science and technology who has written books about topics ranging from the building of a native kayak (“Baidarka”) to the building of a spaceship powered by nuclear bombs (“Project Orion”). He is the author of the bestselling books “Turing’s Cathedral” and “Darwin Among the Machines” which…

Brains, computation and thermodynamics: A view from the future?

by Ashutosh Jogalekar Progress in science often happens when two or more fields productively meet. Astrophysics got a huge boost when the tools of radio and radar met the age-old science of astronomy. From this fruitful marriage came things like the discovery of the radiation from the big bang. Another example was the union of…

Von Neumann in 1955 and 2020: Musings of a cheerful pessimist on technological survival

by Ashutosh Jogalekar “All experience shows that even smaller technological changes than those now in the cards profoundly transform political and social relationships. Experience also shows that these transformations are not a priori predictable and that most contemporary “first guesses” concerning them are wrong.” – John von Neumann Is the coronavirus crisis political or technological?…

The greatest artist

by Ashutosh Jogalekar Neil Shubin’s “Some Assembly Required” is a delightful book whose thesis can be summarized in one word – “repurposing”. As Steve Jobs once put it, “Good artists create. Great artists steal”. By that reckoning Nature is undoubtedly the most magnificent thief and the greatest artist of all time. Repurposing in the history…
