Join the Mathologer and his guest Darth Vader as they explore the Dark Side of the Mandelbrot set. Featuring an introduction to how the Mandelbrot set and the halo surrounding it is conjured up, an ingenious way to visualise what's really going on inside the Mandelbrot set, as well as an appearance of the amazing Buddhabrot fractal.
Special thanks to Melinda Green who discovered the Buddhabrot fractal in 1993 for letting us use her Buddhabrot pictures in this video. Check out her website for more information about this fractal as well as 4d Rubik's cubes, stereophotography, etc.: superliminal.com
Enjoy!

  • The Mandelbrot set was the first chaos math set I programed into my micro back in the late 80's. Took half a day to render. I since found the Logistic map to be far more fascinating - specially when dealing with the point of accumulation. The Mandelbrot contains the Logistic and all the Julia sets. Veritasium explains the Logistic in the Mandelbrot quite well. Worth a look for those who are interested?

    • The "buddhabrot" is particularly interesting to render as it's so much more compute-intensive, and requires atomic memory operations to parallelize easily since any given iteration could potentially read-modify-write any pixel in the image, and has to do so on every iteration of the inner loop. You also need a huge number of samples, far higher than the number of pixels.

    • ***** well, an official name? Iunno. I called it crown of the elves back then because the top structure looked like a crown to me and, well, it's green. Nothing particularly clever :) I guess it's technically an "iterated power mandelbrot set"? - or, well, a buddhabrot variant of that? Something like that. I haven't seen it anywhere else but it's very possible that others had that same idea and made it too. - My dA page is filled mostly with my experiments. It's been a while that I did anything new though. But this video inspired me to try it again for once and I actually have a new one cooking up right now! In general what higher powers do is they up the symmetry of the set. So while power 2 has a single mirror symmetry, power 3 has two mirror axes as well as a 180° rotational symmety. Power 4 has 3 mirror axes and a 3-fold rotational symmetry and this continues forever. However, that only applies to having constant powers. Crown of the Elves, I'm pretty sure, is constrained to a single mirror symmetry because all those symmetries are actually aligned - like, at least one of the main antennas of a power-set (there are as many as rotational symmetries) will always point the same way. So that direction is the only symmetry that's stable throughout all iterations. All the others, if you keep piling on higher and higher powers, essentially vanish away. But you can try completely arbitrary functions. However, not all of them work well. For instance, I tried an exponential function too but that basically didn't work at all. But that might have been a result of the bailout condition. Like, with the simple power sets, i.e. z->z^n+c where n in a fixed Integer, they all have the same bailout condition: If an iteration becomes larger than 2, it will inevitably escape. But with the exponential function, this is wrong. Instead, I think, an entire half plane would be escaping. I didn't quite get that right yet though.

  • drawing a y=x line and "bouncing" it with the x^2+c works because if you have a height of say n, since y=x, where the y=n line meets y=x, x=n, from which you go up (or down) to meet the quadratic again. Sorry if that made no sense

  • Man, I love these videos. They make me feel both really smart and really stupid at the same time. I spent ages trying to figure out basically how the Mandelbrot set works, it hurt my brain. I wish I'd had this video then. Have to admit you kind of lost me with this stuff about tractor beams... definitely gonna have to rewatch that. A while back I was trying to describe the Mandelbrot set in its most basic sense to my girlfriend. I just couldn't find a way to do it. Eventually I figured that maybe I should show her the set at 1 iteration (ie a very basic shape) then 2, 3, 10, 20, whatever, so she'd get the idea that in one sense it's basically a set of mathematically derived shapes nestled within each other, growing more and more complex (soooooooooo complex :P) as they went. Unfortunately... by that point she'd got bored and refused to listen to me any more. Then a bit later we broke up. I don't think it was Mandelbrot related, but... it probably didn't help :P Anyway, thanks for this video. I'd heard of the Buddhabrot but had no idea what it actually was until now.

  • By the way, did you know that if you alternate between three different number systems (complex, split-complex where you have a root j²=1, j!=1 and dual where you have e²=0, e!=0), you get something that very much looks like something belonging to the darkside? orig02.deviantart.net/8dbb/f/2009/190/1/0/battlebrot_by_kram1032.png I can't recall the order though - these images are very sensitive to the exact order. I think it was split-complex -> dual -> complex but I'd have to retry to really know. Haven't played around with this in a while but there are some fun things you can do by mixing up the "standard" Mandelbrot Set formula.

    • Buffoon1980 if you know complex numbers, what I did isn't that big a change. So I assume you do know them. Then you know that multiplication of any two complex numbers is defined as: (a+b i)(c+d i) = a c + a d i + b c i + b d i² = a c + i (a d + b c) + b d i² and here the definition of i comes into play: i²=-1 So: a c - b d + i (a d + b c) Now what I did amounts to changing the definition of i to either be i²=+1 or i²=0 And to avoid confusion, I renamed "i" in each of those cases. So I define: j²=1, e²=0 and I get: (a+b j)(c+d j) = a c + a d j + b c j + b d j² = a c + j (a d + b c) + b d j² = | j²=1 a c + b d + j (a d + b c) or (a+b e)(c+d e) = a c + a d e + b c e + b d e² = a c + e (a d + b c) + b d e² = | e²=0 a c + e (a d + b c) And basically, which of those variations I do, I vary on each step. Of course, the actual Mandelbrot iteration is: z -> z²+c which, if z=x+iy and c=a+ib, expands to: x-> x²-y² + a y-> 2 x y + b But if I instead go: z=x+jy, I get: x -> x²+y² + a y -> 2 x y + b And finally, if I use z=a + eb: x -> x² + a y -> 2 x y + b So it's just a small modification of my iteration. Each of those three variants obviously give very different pictures if you plot their orbits. But I didn't just use each of them separately. Instead, I alternated between them. There are many ways you could do this but I chose a sequence where all three variants are called in the same order. Of this there still are six variants (ije,jie,iej,jei,eij,eji). I'm not entirely sure which one of those I picked to produce the above image but I think it was jei. So my final algorithm, I think, looks like this: x1 = x0² + y0² + a y1 = 2 x0 y0 + b x2 = x1² + a y2 = 2 x1 y1 + b x3 = x2² - y2² + a y3 = 2 x2 y2 + b and from there it'd repeat, so: x4 = x3² + y3² + a y4 = 2 x3 y3 + b etc. I know this can seem like much at first, but if you invest just a few minutes into this - maybe just manually carry out a couple of these, as was done in the video, to see what happens, you should get a sense for this. It's really not too difficult. The largest barrier is that it's a new, unfamiliar concept. __________ Technical note (this is completely unnecessary to understand the above, so feel free to ignore): Actually, come to think of it, it might be that I actually, "technically" did the iteration eij instead, depending on how you pick the starting value: Usually, these images are initialized with z0=0, which means that the first iteration, no matter which of the above you start with, will give you z1 = a + b _ where _ stands for e, i or j, depending on your current iteration. For the above scheme, z1 = a + b e But there is nothing from stopping you to initialize z0 = a + b _ in which case you'll get a picture as if the whole iteration was done one later. In a variant of the algorithm you actually start with z0 randomly. This, then, gives the so-called "Buddhagram". For the normal Buddhabrot rendering of the Mandelbrot Set that mostly means some extra fuzziness. But for something like the above alternated scheme, it might mean something rather different. I should really try that some time...

    • Kram1032 Aw man, I reeeeally hope you didn't type all that solely for my benefit, because it's going to be 99.9% lost on me. I mean, I'll give it a look, but since you start off by saying you assume I know complex numbers, I could be in trouble... because I pretty much don't :P I could maybe give you the dictionary definition, but... there's a pretty good chance I might be thinking of irrational numbers. Or imaginary numbers. Or grandiloquent numbers, which as far as I know is something I just made up, but may actually exist. That's how ignorant I am :P But, I appreciate the effort!

And then I experimented with outher techniques and also just made some Buddhabrots: imgur.com/a/NVpIO#0.
