Last year I replaced several windows in my house and they were the expensive double-pane energy efficient kind. But this week I got a call from the contractor complaining that his work has been completed for a whole year and I had yet to pay for them.
Boy oh boy did we go 'round. Just because I'm blonde doesn't mean that I am automatically stupid. So, I proceeded to tell him just what his fast talking sales guy had told me last year. . that in one year the windows would pay for themselves. There was silence on the other end of the line so I just hung up and I haven't heard back. Guess I must have won that silly argument.

Karl Pearson

Died 27 Apr 1936 at age 79 (born 27 Mar 1857). English mathematician who was one of the founders of modern statistics. His lectures as professor of geometry evolved into The Grammar of Science (1892), his most widely read book and a classic in the philosophy of science. Stimulated by the evolutionary writings of Francis Galton and a personal friendship with Walter F.R. Weldon, Pearson became immersed in the problem of applying statistics to biological problems of heredity and evolution. The methods he developed are essential to every serious application of statistics. From 1893 to 1912 he wrote a series of 18 papers entitled Mathematical Contributions to the Theory of Evolution, which contained much of his most valuable work, including the chi-square test of statistical significance.
