Allegedly, when Benoit B. Mandelbrot used to be asked what the "B" in his name stood for, he would reply: _The B? It stands for Benoit B. Mandelbrot!_ Legend.

There is a function f(x) = x^2 + c. You calculate function on f(0), then on f(f(0)), then on f(f(f(0))), and so on forever. Either the result grows towards infinity, or the result remains in some small range. If it grows forever for a certain number c (which is a complex number, so it is a point on a plane), then it isn't part of the set, otherwise it is part of the set.

@hweigel528

Someone asked, "why is two the bound after which everything blows up?", which is a very good question. The reason becomes more intuitive if you know a few important properties of complex numbers, namely that |u*v| = |u|*|v| for all complex numbers u and v, and that |u + v| >= |u| - |v| for all complex numbers u and v. Using these two properties, consider the magnitude of a given number going through this procedure. Given that z has magnitude |z|, f(z) = z^2 + c has magnitude |f(x)| = |z^2 + c| >= |z^2| - |c| = |z|^2 - |c|. Now we can consider a function based on some |c| >2. Clearly f(0) = 0^2 + c = c, and so |f(0)| = |c| > 2. Next, f(c) = c^2 + c = c*(c+1), and so |f(c)| = |c|*|c+1|, and since |c|>2, |c+1| >=|c|-|1|>1. Therefore |f(c)|=|c|*|c+1|>|c|. Now, assume that we have done this procedure enough times to reach some arbitrary number z, such that |z| > |c| > 2. (We already know that we reach a number with this property after two steps). |f(z)| = |z^2 + c| >= |z|^2 - |c| > |z|^2 - |z| = |z|*(|z|- 1). Since |z| > 2, |z| - 1 > 1, and therefore |f(z)| > |z|*(|z| - 1) > |z|. Since this is true FOR ALL |z| > |c|, we know that |z| < |f(z)| < |f(f(z))| < |f(f(f(z)))|

Dr. Krieger is remarkable, and the series of Numberphile videos on Mandelbrot with Dr. Krieger are all extremely clear and interesting.

+Numberphile Quoting Mandelbrot , about the inventor of fractals is a scam ! This man has only stolen the position of the creator of this part of geometric art . As any thief of intellectual property , he is obliged to erase any natural occurrence of the actual inventor's name . This true inventor was Helge Von Koch , a Swedish mathematician ( # 1906), and the first fractal known was " the fractal of Koch ". That's why Mandelbrot imposed the name " snow flake " to this first known fractal , whose genuine name was " the flake of Koch " . Doing so , he erased the name of this annoying guy that he was trying to rob . Later on, Mandelbrot exerted a real terror pressure over any mathematical publication ,and threatened anyone that dared talk about fractals without quoting him as the almighty father . Render to Cesar ... Mandelbrot invented the word " fractal" . But no more .

Numberphile -- Question: say I take a single number line, a one dimensional continuum of numbers, such as the x-axis of a graph. If I use complex numbers, it stands to reason that on this number line is another axis perpendicular to the x-axis at 0 for the complex parts of x -- in effect, our one-dimensional number line is two-dimensional. Say then that I take this complex x-plane and add, perpendicular to it at 0, a y-axis, so now my graph is three dimensional -- a complex x-plane and a real y-axis. If I then extend the y-axis to include the complex numbers by adding yet another axis perpendicular to the y-axis AND the complex-x plane to represent the y-axis' complex part, I now have a four-dimensional system with only two variables, x and y. Can I do equations in four-dimensional space using this system?

It's really not complicated : for each pixel, it takes the corresponding complex number and iterates the z²+c thing several times, breaking out whenever the magnitude is greater than 2. If it gets to the end of the loop it's probably in the set, so it considers the pixel is. Drawing it with a gradient is a bit more complicated.

Dr. Krieger, glad to see you're doing well for yourself. You once tutored me at UIC in remedial math courses and told me I had to be more "methodical", although it's a shot in the dark if you remember. I can write programs that multiply matrices, now. Cheers.

Why must it be less than "2"? Why not "3" or "9834953479" or whatever? Do _you_ choose the boundary, or is that just a property of the set?

Intrafacial86 if you let c=-2, you will get z0=0, z1=-2, z2=2, z3=2... because 2^2-2=2. for c= any number x, in between 0 and -2, x^+x

very interesting video, but i miss the videos brady used to do on numberphile, about primes and conjectures (specifically james grimes and matt parker; pi, grahams number, abc conjecture, enigma machine etc). yes they were simple, short videos, but they were fun and didn't make my head hurt! any chance for some more 'fun' 'easily accessible' videos mixed in with these newer, somewhat more advanced topics?
