Bernhard Riemann was born 200 years ago today. His ideas concerning geometry of space had a profound effect on the development of modern theoretical physics. He clarified the notion of integral by defining what we now call the Riemann integral. mathshistory.st-andrews.ac.uk/Biog… www.maths.tcd.ie/pub/HistMath/Peop…

The term "regression" in Regression Analysis comes from Sir Francis Galton, who in the 1870s-80s observed that offspring characteristics (originally in sweet peas, later confirmed in human height) tend to regress toward the population mean rather than resembling their parents' extremes en.wikipedia.org/wiki/Regression_t…
