consequences of Chandra's first research paper were more far reaching than anyone could have imagined.

Chandra took up his studies at Cambridge and spent a lonely but productive year in intensive study and research. Sitalakshmi died on May 21, 1931, adding grief to his loneliness. Chandra was introduced to the monthly meetings of the Royal Astronomical Society and became acquainted with E. Λ. Milne and P. Λ. M. Dirac. Chandra devoted his research efforts to calculating opacities and applying his results to the construction of an improved model for the limiting mass of the degenerate star. Milne was enthusiastic about the work, but it turned out later that his enthusiasm was based more on his rivalry with A. S. Eddington than on an appreciation of the scientific merits.

The year of intensive study at Cambridge moved Chandra to look for a change of scenery, and at the invitation of Max Born he spent the summer of 1931 at Born's institute at Gottingen. There he became acquainted with Ludwig Biermann, Edward Teller, Leon Brillouin, and Werner Heisenberg. Back at Cambridge in the autumn Chandra continued his work on atomic absorption coefficients and mean opacities, but with a growing sense of frustration from his feeling that he was abandoning mathematics through his pursuit of physics and abandoning pure physics through his pursuit of astrophysics. Chandra was invited to present his results on model stellar photospheres at the January 1932 meeting of the Royal Astronomical Society (RAS) and was complimented by both Milne and Eddington following the presentation.

Chandra's feeling of frustration with his "peripheral science" led to his spending his third year at Bohr's institute in Copenhagen. He adapted readily to the informal atmosphere and became acquainted with Victor Weisskopf, Leon Rosenfeld, M. Debrueck, H. Kopferman, and others. During
