S Chandrasekhar, popularly referred to as Chandra, used to be one of many most popular scientists of the 20 th century. The yr 2010 marks the start centenary of Chandra. His designated form of examine, inward certain, looking a private viewpoint to grasp a specific box, after which go directly to one other was once so distinct that it'll draw massive curiosity and a focus between students. As Chandra elucidates within the preface, "The a number of installments describe intimately the evolution of my medical paintings prior to now 40 years and documents each one research, describing the doubts and the successes, the pains and the tribulations. And the components my quite a few affiliates and assistants performed within the crowning glory of the several investigations are detailed". it's certainly a outstanding and infrequent record, interesting to learn and adventure the thrill, frustrations and struggles of an artistic brain.  Read more...

Example text

Again in March, I was occupied with routine matters. But the elimination of the constants was the first problem to tackle. And while I had thought of this on and off, I had not concentrated on it. But now this was the only outstanding problem. So, one weekend I sat down and formulated the basic problem. The basic mathematical problem as formulated in XXI (Sec. 3) was achieved during this weekend. I remember taking Ledoux to Walworth that Sunday morning and expressing my confidence that the problem could be solved.

It was clear that if my theory of turbulence was along the right lines, then it could be extended to hydromagnetic turbulence as well. A problem which had occurred to me in 1949–50 (and about which I had talked to Fermi at that time) came to the fore: the problem concerns an elementary theory of hydromagnetic turbulence along the lines of Heisenberg’s theory of hydrodynamic turbulence. This question occupied me during my seminars during the winter. The problem was finally resolved; and I was astonished that the theory gave two modes.

It was during this time that it occurred to me (while driving to Chicago on a Thursday) that one might choose the set of moment equations by considering the correlations at two different instants at two different places and then using the quasi Gaussian approximation. I discussed these ideas with Fermi during lunch one day and he seemed quite interested in them. I felt at this time that I had made a real break in the theory of turbulence; but this elation and the hopes that it raised were soon to be dashed.
