Derek Muller explains how the simple logistic map equation leads to chaos, bifurcation, and the Mandelbrot set.

The logistic map connects fluid convection, neuron firing, the Mandelbrot set and so much more. Fasthosts Techie Test competition is now closed!

What people say. Recommended as a mind-bending explanation of chaos theory, fractals, and how complex patterns emerge from simple mathematical rules.

On “The 3x+1 Problem [video]”

Absolutely. His "gravity is not a force" video led me through a whole range of emotions from "this is ridiculous" to "actually..." to "holy crap, I've been wrong about this my entire life". In terms of sheer brain-breaking... this is my favourite: link to this video But this is the one I think people on HN need to watch most link

Have you ever seen the Veritasium video on where fractals actually come from in 3D? If not, and since you already thought fractals were fascinating, hold on to your hat. link to this video

Did you see his one about the 3D landscape underlying the Mandelbrot set? I’ll cut him endless slack after that mindsplosion. link to this video

On “Why 10B snow crabs starved to death in the Bering Sea”

Here’s a rabbit hole to go down on that theme - link to this video That’s my second favorite YouTube video. I love how it reveals some universal primitives are really complicated. The pattern in the video is as fundamental to the universe as circles are. Imagine how many other mind-boggling structures are ubiquitous but just outside our understanding.

On “Misunderstanding Malthus’ mistake”

…tastrophic line-crossing. At that point, you basically have an actual Minimal Viable Product that you can use to predict and think about real-world population dynamics, and a whole lot more besides. Over the last two centuries people have built a lot of discoveries on top of that. This Veritasium video is about one small (but awesome) bit of that: link to this video It's a good thing not everyone thought Malthus was (completely) wrong!…

On “You're enlightened – now what?”

Thanks for making that video emphasizing the idea of resonance and commercial design -- as well as social change. Parts of the video on resonance reminds me of this one: "This equation will change how you see the world (the logistic map)" link to this video Some other parts on design remind me of videos by Charles and Ray Eames. You might want to consider adding Dialogue Mapping using IBIS to your design process if you have not already? link
