Carl Wolfgang Benjamin Goldschmidt
Carl Wolfgang Benjamin Goldschmidt was a German astronomer, mathematician, and physicist of Jewish descent who was a professor of astronomy at the University of Göttingen. He is also known as Benjamin Goldschmidt, C. W. B. Goldschmidt, Carl Goldschmidt, and Karl Goldschmidt.
Mathematical works
A student of Carl Friedrich Gauss and an assistant to Gauss at the university observatory, Goldschmidt frequently collaborated with Gauss on various mathematical and scientific works. Goldschmidt was in turn a professor of Gauss's protégé Bernhard Riemann. Data gathered by Gauss and Goldschmidt on the growth of the logarithmic integral compared to the distribution of prime numbers was cited by Riemann in "On the Number of Primes Less Than a Given Magnitude", Riemann's seminal paper on the prime-counting function.In 1831, Goldschmidt wrote a mathematical treatise in Latin, "Determinatio superficiei minimae rotatione curvae data duo puncta jungentis circa datum axem ortae". The paper dealt with the problem in the calculus of variations of determining the minimal surface of revolution, the surface of revolution of the planar curve between two given points which minimizes surface area. Solutions to the problem exist which are not continuous; such discontinuous solutions are known as Goldschmidt solutions in honor of Goldschmidt's discovery of them.
