Edward Feigenbaum
Edward Albert Feigenbaum (born January 20, 1936) is a computer scientist working in the field of artificial intelligence, and joint winner of the 1994 ACM Turing Award. He is often called the "father of expert systems." Education and early life Feigenbaum was born in Weehawken, New Jersey in 1936 to a culturally Jewish family, and moved to nearby North Bergen, where he lived until the age of 16, when he left to start college. Knuth, Don"Oral History of Edward Feigenbaum'' Computer History Museum, 2007. Accessed October 23, 2015. "I was born in Weehawken, New Jersey, which is a town on the Palisades opposite New York. In fact, it’s the place where the Lincoln Tunnel dives under the water and comes up in New York. Then my parents moved up the Palisades four miles to a town called North Bergen, and there I lived until I was 16 and went off to Carnegie Tech." His hometown did not have a secondary school of its own, and so he chose Weehawken High School for its college preparatory p ...

Feigenbaum Constants
In mathematics, specifically bifurcation theory, the Feigenbaum constants are two mathematical constants which both express ratios in a bifurcation diagram for a non-linear map. They are named after the physicist Mitchell J. Feigenbaum. History Feigenbaum originally related the first constant to the period-doubling bifurcations in the logistic map, but also showed it to hold for all one-dimensional maps with a single quadratic maximum. As a consequence of this generality, every chaotic system that corresponds to this description will bifurcate at the same rate. Feigenbaum made this discovery in 1975, and he officially published it in 1978. The first constant The first Feigenbaum constant is the limiting ratio of each bifurcation interval to the next between every period doubling, of a one-parameter map :x_ = f(x_i), where is a function parameterized by the bifurcation parameter . It is given by the limit :\delta = \lim_ \frac = 4.669\,201\,609\,\ldots, where are discret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitchell Feigenbaum
Mitchell Jay Feigenbaum (December 19, 1944 – June 30, 2019) was an American mathematical physicist whose pioneering studies in chaos theory led to the discovery of the Feigenbaum constants. Early life Feigenbaum was born in Philadelphia, Pennsylvania, to Jewish emigrants from Poland and Ukraine. He attended Samuel J. Tilden High School, in Brooklyn, New York, and the City College of New York. In 1964, he began his graduate studies at the Massachusetts Institute of Technology (MIT). Enrolling for graduate study in electrical engineering, he changed his area of study to physics. He completed his doctorate in 1970 for a thesis on dispersion relations, under the supervision of Professor Francis E. Low. Career After short positions at Cornell University (1970–1972) and the Virginia Polytechnic Institute and State University (1972–1974), he was offered a longer-term post at the Los Alamos National Laboratory in New Mexico to study turbulence in fluids.

Feigenbaum Function
In the study of dynamical systems the term Feigenbaum function has been used to describe two different functions introduced by the physicist Mitchell Feigenbaum: * the solution to the Feigenbaum-Cvitanović functional equation; and * the scaling function that described the covers of the attractor of the logistic map Feigenbaum-Cvitanović functional equation This functional equation arises in the study of one-dimensional maps that, as a function of a parameter, go through a period-doubling cascade. Discovered by Mitchell Feigenbaum and Predrag Cvitanović,Footnote on p. 46 of Feigenbaum (1978) states "This exact equation was discovered by P. Cvitanović during discussion and in collaboration with the author." the equation is the mathematical expression of the universality of period doubling. It specifies a function ''g'' and a parameter by the relation : g(x) = - \alpha g( g(\frac x ) ) with the initial conditions * ''g''(0) = 1, * ''g''′(0) = 0, and * ''g''′′ ...

Eran Raven
Eran Raven is a mentalist and security expert. Raven is best known in technology circles by his birth name, Eran Feigenbaum, for his role as both the former director of security at Google Enterprise (2007-2016), and the former chief information security officer for Jet.com. Raven is famous in the US for his death-defying mentalism performances on NBC’s Phenomenon. Early life Eran Raven was born Eran Feigenbaum in Tel Aviv, Israel. His mother was a high school principal and his father was a rocket scientist. His interest in magic began at an early age, and he gave his first public performance at age 11. He became interested in mentalism after he realized the way he asked questions could influence the person's response, or willingness to respond, to the request. Raven became fascinated by, and would make much use of, this nonverbal communication. Appearances Raven has appeared on stage in more than 35 countries in North America, Europe and Asia; and on more than 50 TV shows in ...

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, but ...

Jewish Surnames
Jewish surnames are family names used by Jews and those of Jewish origin. Jewish surnames are thought to be of comparatively recent origin; the first known Jewish family names date to the Middle Ages, in the 10th and 11th centuries CE. Jews have some of the largest varieties of surnames among any ethnic group, owing to the geographically diverse Jewish diaspora, as well as cultural assimilation and the recent trend toward Hebraization of surnames. Some traditional surnames relate to Jewish history or roles within the religion, such as Cohen ("priest"), Levi, Shulman ("synagogue-man"), Sofer ("scribe"), or Kantor ("cantor"), while many others relate to a secular occupation or place names. The majority of Jewish surnames used today developed in the past three hundred years. History Historically, Jews used Hebrew patronymic names. In the Jewish patronymic system the first name is followed by either ''ben-'' or ''bat-'' ("son of" and "daughter of," respectively), and then the ...
