Banesh Hoffmann
Banesh Hoffmann (6 September 1906 – 5 August 1986) was a British mathematician and physicist known for his association with Albert Einstein. Life Banesh Hoffmann was born in Richmond, Surrey, on 6 September 1906. He studied mathematics and theoretical physics at the University of Oxford, where he earned a Bachelor of Arts degree and went on to earn his doctorate at Princeton University. While at the Institute for Advanced Study in Princeton, Hoffmann collaborated with Einstein and Leopold Infeld on the classic paper Gravitational Equations and the Problem of Motion. Einstein's original work on general relativity was based on two ideas. The first was the equation of motion: that a particle would follow the shortest path in four-dimensions space-time. The second was how matter affects the geometry of space-time. What Einstein, Infeld, and Hoffmann showed was that the equation of motion followed directly from the field equation that defined the geometry (see main article). In 1937, Hoffmann joined the mathematics department of Queens College, part of the City University of New York, where he remained until the late 1970s. He retired in the 1960s but continued to teach – in the fall a course on classical and quantum mechanics and
