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…

Spooky factions at a distance

by Ashutosh Jogalekar For me, a highlight of an otherwise ill-spent youth was reading mathematician John Casti’s fantastic book “Paradigms Lost“. The book came out in the late 1980s and was gifted to my father who was a professor of economics by an adoring student. Its sheer range and humor had me gripped from the…

Mathematics, and the excellence of the life it brings

by Ashutosh Jogalekar Mathematics and music have a pristine, otherworldly beauty that is very unlike that found in other human endeavors. Both of them seem to exhibit an internal structure, a unique concatenation of qualities that lives in a world of their own, independent of their creators. But mathematics might be so completely unique in…

Computer Simulations And The Universe

by Ashutosh Jogalekar There is a sense in certain quarters that both experimental and theoretical fundamental physics are at an impasse. Other branches of physics like condensed matter physics and fluid dynamics are thriving, but since the composition and existence of the fundamental basis of matter, the origins of the universe and the unity of…
