  2. Mandelbrot set - Wikipedia

    en.wikipedia.org/wiki/Mandelbrot_set

    The quaternion (4-dimensional) Mandelbrot set is simply a solid of revolution of the 2-dimensional Mandelbrot set (in the j-k plane), and is therefore uninteresting to look at. [43] Taking a 3-dimensional cross section at d = 0 ( q = a + b i + c j + d k ) {\displaystyle d=0\ (q=a+bi+cj+dk)} results in a solid of revolution of the 2-dimensional ...

    One of them, his nephew Benoit Mandelbrot, was to discover the Mandelbrot set and coin the word fractal in the 1970s. In 1939 he fought for France when the country was invaded by the Nazis, then in 1940, along with many scientists helped by Louis Rapkine and the Rockefeller Foundation , Mandelbrojt relocated to the United States, taking up a ...

    Benoit B. Mandelbrot [a] [b] (20 November 1924 – 14 October 2010) was a Polish-born French-American mathematician and polymath with broad interests in the practical sciences, especially regarding what he labeled as "the art of roughness" of physical phenomena and "the uncontrolled element in life".

    en.wikipedia.org/wiki/Pi

    An occurrence of π in the fractal called the Mandelbrot set was discovered by David Boll in 1991. [199] He examined the behaviour of the Mandelbrot set near the "neck" at (−0.75, 0) . When the number of iterations until divergence for the point (−0.75, ε ) is multiplied by ε , the result approaches π as ε approaches zero.

    John Hamal Hubbard (born October 6 or 7, 1945) is an American mathematician and professor at Cornell University and the Université de Provence.He is known for the mathematical contributions he made with Adrien Douady in the field of complex dynamics, including a study of the Mandelbrot set.

    The Mandelbrot set is a fractal that is defined as the set of points in the complex number plane for which + = + with z 0 = 0 does not tend to infinity. The Mandelbrot set was first defined by Pierre Fatou in 1905, and first plotted on computer by Benoît Mandelbrot. The color reflects the number of iterations it takes to reach a certain ...
