Editing Subrahmanyan Chandrasekhar (section)

===Other activities===

From 1952 to 1971 Chandrasekhar was editor of ''[[The Astrophysical Journal]]''.<ref>{{Cite journal | author=Helmut A. Abt | date=1 December 1995 | title= Obituary – Chandrasekhar, Subrahmanyan | journal=Astrophysical Journal | volume=454 | pages=551 | bibcode=1995ApJ...454..551A|doi = 10.1086/176507 | issn = 0004-637X}}</ref> When [[Eugene Parker]] submitted a paper on his discovery of [[solar wind]] in 1957, two eminent reviewers rejected the paper. However, since Chandra as an editor could not find any mathematical flaws in Parker's work, he went ahead and published the paper in 1958.<ref>{{cite journal |last1=Parker |first1=E.

During the years 1990 to 1995, Chandrasekhar worked on a project devoted to explaining the detailed geometric arguments in Sir [[Isaac Newton]]'s ''[[Philosophiae Naturalis Principia Mathematica]]'' using the language and methods of ordinary calculus.  The effort resulted in the book ''Newton's Principia for the Common Reader'', published in 1995.

Chandrasekhar also worked on collision of gravitational waves,<ref>{{cite journal|last1=Chandrasekhar|first1=S.|last2=Xanthopoulos|first2=B.
