Posthumous edition of father of modern physics Albert Einstein's historic 1921 Princeton lectures, an overview of his then-controversial theory of relativity, originally published in 1923 and revised here – the first edition to include his last scientific paper before his death, "Relativistic Theory of the Non-Symmetric Field." Early ownership inscription to front free endpaper: "Ranck / Chicago / November 1956." Neuroscientist James B. Ranck Jr. (1930-) is a distinguished professor of Physiology at SUNY Downstate Medical Center who discovered head direction cells in 1984; he interned at the University of Chicago in 1955-56. Light foxing to endpapers, rear inner hinge darkened from binder’s glue; unclipped dust jacket moderately toned and soiled, some chipping to spine-ends and edges. Very good. Item #889
