Armand Vallin Feigenbaum (April 6, 1920 [1] – November 13, 2014) was an American quality control expert and businessman. [2] He devised the concept of Total Quality Control (TQM), now known as " total quality management ".
The most common method of using shortened footnotes is with the {} template for the shortened footnotes, and {} templates for the full citation. The Citation Style 1 and Citation Style 2 templates automatically create an anchor for an {} link, using the author last name and the year. An "anchor" is a landing place for a link to jump to.
The ability to collapse note windows, which is present in all versions of Stickies, is a holdover from System 7.5's WindowShade feature. The window button layout, which is unusual for a modern macOS application, is retained from Mac OS 8. In macOS Big Sur, the icon has been changed to look like a stack of sticky notes in a rounded square design.
EPAM (Elementary Perceiver and Memorizer) is a psychological theory of learning and memory implemented as a computer program. Originally designed by Herbert A. Simon and Edward Feigenbaum to simulate phenomena in verbal learning, it has been later adapted to account for data on the psychology of expertise and concept formation.

Feigenbaum was an expert in programming languages and heuristics, and helped Lederberg design a system that replicated the way Djerassi solved structure elucidation problems. [1] They devised a system called Dendritic Algorithm (Dendral) that was able to generate possible chemical structures corresponding to the mass spectrometry data as an output.
The first Feigenbaum constant δ is the limiting ratio of each bifurcation interval to the next between every period doubling, of a one-parameter map + = (), where f(x) is a function parameterized by the bifurcation parameter a. It is given by the limit [1]
To see how this number arises, consider the real one-parameter map =.Here a is the bifurcation parameter, x is the variable. The values of a for which the period doubles (e.g. the largest value for a with no period-2 orbit, or the largest a with no period-4 orbit), are a 1, a 2 etc.
