The German born theoretical physicist composed this letter to Polish- American physicist Ludwik Silberstein as he had earlier disputed part of Einstein’s theory of general relativity.
Both the intellectuals had their differences of opinion but Silberstein had reportedly agreed with Einstein after this correspondence. This letter has been put up for auction by the great-great-grandchildren of Silberstein.
