John Wilder Tukey (/ ˈ t uː k i /; June 16, 1915 – July 26, 2000) was an American mathematician and statistician, best known for the development of the fast Fourier Transform (FFT) algorithm and box plot.
John W. Tukey was one of the most, if not the most, influential mathematical and theoretical statisticians of the 20th Century. During World War II, he worked on antiaircraft, armored vehicle and aircraft fire control problems, and aerodynamic feasibility, all of which led eventually to the development of the Nike Ajax missile in the late 1940s.
Overview. Tukey defined data analysis in 1961 as: "Procedures for analyzing data, techniques for interpreting the results of such procedures, ways of planning the gathering of data to make its analysis easier, more precise or more accurate, and all the machinery and results of (mathematical) statistics which apply to analyzing data."
Since the mathematician John W. Tukey first popularized this type of visual data display in 1969, several variations on the classical box plot have been developed, and the two most commonly found variations are the variable width box plots and the notched box plots shown in Figure 4.
He attributed its origin to John W. Tukey, who had written a Bell Labs memo on 9 January 1947 in which he contracted "binary information digit" to simply "bit". Vannevar Bush had written in 1936 of "bits of information" that could be stored on the punched cards used in the mechanical computers of that time.
In 2000, Fred Shapiro, a librarian at the Yale Law School, published a letter revealing that John Wilder Tukey's 1958 paper "The Teaching of Concrete Mathematics" contained the earliest known usage of the term "software" found in a search of JSTOR's electronic archives, predating the OED's citation by two years.
Prince Octavius of Great Britain (1779–1783) was the thirteenth child and eighth son of King George III and his queen consort, Charlotte of Mecklenburg-Strelitz.King George and Queen Charlotte were much more involved in rearing their fifteen children than was usual for aristocratic parents of the time.
C'est en 1965 que James Cooley et John Tukey publient l’article qui « lance » définitivement l'adoption massive de cette méthode en traitement du signal et dans les télécommunications. On a découvert par la suite que l'algorithme avait déjà été imaginé par Carl Friedrich Gauss en 1805 , et adapté à plusieurs reprises (notamment ...
The Cooley–Tukey algorithm, named after J. W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm. It re-expresses the discrete Fourier transform (DFT) of an arbitrary composite size = in terms of N 1 smaller DFTs of sizes N 2, recursively, to reduce the computation time to O(N log N) for highly composite N (smooth numbers).
2. Data Science “Versus” Statistics. Many of my audience at the Tukey Centennial—where these remarks were originally presented—are applied statisticians, and consider their professional career one long series of exercises in the above “…collection, management, processing, analysis, visualization, and interpretation of vast amounts of heterogeneous data associated with a diverse ...
