As a little girl climbed onto Santa's lap, he asked her the usual question, "And what would you like for Christmas?"
The child stared at him open mouthed and horrified for a minute, then gasped, "Didn't you get my text?"
Antoni ZygmundBorn 26 Dec 1900; died 30 May 1992 at age 91. Polish-American mathematician who created a major analysis research centre at Chicago, and recognized in 1986 for this with the National Medal for Science. In 1940, he escaped with his wife and son from German controlled Poland to the USA. He did much work in harmonic analysis, a statistical method for determining the amplitude and period of certain harmonic or wave components in a set of data with the aid of Fourier series. Such technique can be applied in various fields of science and technology, including natural phenomena such as sea tides. He also did major work in Fourier analysis and its application to partial differential equations. Zygmund's book Trigonometric Series (1935) is a classic, definitive work on the subject.« |
