@@Wolffanghurricane I will add spice to the topic. Time has no direction - past, present and future are only happening in our heads. We record data of reality as it constantly changes. What data we have about it defines the past, and the predictability of the system’s effects defines the future. But really, time isn’t like this so your statement is simply wrong. Visual communication isn’t past nor future, it’s present and will always stay like that, it’ll only change (evolve).

In 1988, using a 386 based Windows PC, I built many Mandelbrot and Julia sets, one pixel at a time, and each image took a day or two to complete. Now, with processor speeds in the gigahertz and multicore processors working in parallel, each image takes milliseconds to complete. Was very interesting to watch the machine back then do the calculations and plot the pixels on the screen. Now, all the math is done in a flash. Shows how far we have come in technology. Still love the Mandelbrot images. They are seen everywhere in nature.

@@DailyCakeSlice for the most part you get paid to teach maths to others. despite its wide applications, the study and discovery of mathematics is a relatively narrow field. That said, there are plenty of jobs within that narrow field available. Plenty of schools ranging from beginning grade school all the way up to university need passionate mathemeticians to teach maths to their young students. Some professors make quite a lot of money studying their passion, and since passion is what drives both teaching and learning, that's the best career for anyone who loves maths.

@@DailyCakeSlice Math is needed in almost all fields of computer science. As a game developer you need quite a bit of math. Of course it always depends on what you want to do. However understanding vectors, matrices and quaternions is quite important if you do 3d graphics. In the game industry there are even other jobs like game design which is more about probability and balancing features. They usually toy around a lot with exponentials ^^. Though it depends on how deep you dive into certain topics. Procedural geometry or neural networks are also quite math heavy. Same goes for bezier curves or splines. Realistically speaking in almost all fields there are jobs that require some level of math. Yes, the requirement of a pure mathematician is kinda rare, but math skills are required everywhere ^^.

I must try this out on some of my know it all acquaintances.

I’m not a math nerd but this is fascinating and also makes beautiful art!

[@michaeldoan6837]

Absolutely astounding.. Thank you for presenting this in a way I can understand. Has always intrigued me, but never been able to get my head around it. Well done.

[@joshcohen6800]

ive been obsessed with fractals and the mandlebrot set from the moment i saw them... my jaw was dropped this WHOLE video and i barely understand it, yet it makes so much sense! thank you thank you! i LOVE this video!

[@numberphile]

Glad you liked it.

[@procactus9109]

This is your best video to date! I actually understand this and can code it from memory of this video. Thank you very much for this.

[@michaeldeierhoi4096]

Marvelous explanation of how the Mandelbrot Set came together. If would have to see this explained probably a few times to really begin to understand it.

[@kilianbalter]

When i programmed a Julia/Mandelbrot Set visualization/exploration program as an assignment the moment where i got the calculations right and the resolution high, and the beautiful shape popped up was so satisfying. Truly amazing piece of mathematics.

[@elenakat1497]

Wow, Ben is a fantastic communicator! Well done!

[@Charles_Reid]

The idea that the Mandelbrot set looks like the corresponding Julia set at the point of interest is so cool. Numberphile is such a good channel

[@healthdios]

Awesome video..! I first heard of the Mandelbrot set when in design school and never made any sense why that shape was always appearing. With this explanation every detail is explained and never got lost on intricate descriptions....but the best part about this presentation is Hollies voice and pictures sprinkled sparingly throughout the video.

[@paolomanzo2007]

It's always surprising how that simple formula can generate such a beautiful mathematical monster 🙂

[@swinde]

Many of our plants and animals have features that are mathematical. There is a fractal that produces a fern, for example.

[@kartoffelmozart]

agreed. Im totally blown away by the contrast between chaos and predictability in those images. It's truly beautiful.

[@theshimonmor]

Thank you for the clear and visual explanation of a mind-bending (for mere mortals) topic. Well done.

[@JJ-kl7eq]

A useful numbering system for briefcases on Deal Or No Deal hosted by Howie Mandelbrot.

[@skarrambo1]

The joke doesn't work quite as well in the UK, where it was hosted by Noel Edmonds - and no-one wants an iteration of him, or Mr. Blobby

[@DeclanMBrennan]

I thought you were making a Brexit joke for a minute. Now there's an example of iterative instability. :-)

[@kerrief3414]

I'm not mathematical but I'm obsessed with this.

[@kirklandau2826]

But this is “mathematical” inherently... I’m struggling to make any sense of your comment, it seems contradictory.

[@aadityamohan9962]

This video is remarkably one of the most best videos on Mandelbrot Set👍👍

[@arthurdequeiroz8393]

First time I actually understood the set ! Absolutely amazing video. Congrats to both.

[@inshadowz]

Thanks for mentioning James Gleich's "Chaos" :) Been ages since I read it, had almost forgotten about it, but along with the appendixes to Arthur C. Clarke's "The Ghost from the Grand Banks" (which is science fiction but involves fractals), it gave me the first inkling of understanding what fractals are and how they work. Thanks to you it's now safely in store on my Kindle :D

[@jaimerios1378]

Well done! Well done video. Seriously. This made my day. Looking for vids on the Mandelbrot Set and ... this nailed it. Thanks!

[@dancemachine497]

Fantastic video! Very well explained and yet does not take away from the intense mindboggling experience i have with this.

[@tantzer6113]

Amazing video with wonderfully clear explanations. Thank you so much!

[@Nahobino777]

Why do i feel the Mandelbrot set is a bit related to the universe's structure? I know i must be so wrong but it's just a thought. This video is one of the best i've seen about the Mandelbrot set. It's really understandable, interesting and informative. Thank you!

[@ZeezerZ]

You're correct, search "Watch the Synchronized dance of a 6-Planet system. Also in mandelbrot you can see the Fibonacci sequence which you can see in things as small as sunflowers

[@giovannysoto4151]

This is by far one of my favourites videos from youtube!

I've always been fascinated by Mandelbrot set and Julia sets ...it's very complex ..but now I understand more with this video. Thanks

This was just beautiful. Thank you for sharing the geogebra files! I am going to use this with my students.

Best explanation of the Julia and Mandelbrot sets I've ever watched! Thank you :D

[@justinjohnstone1043]

Bravo. you allowed me to understand this stuff, I assumed it was too complex, but no - yoru explanation was clear and simplet ot follow. The tools are awesonme to play with yourself. Loved this. Thank you Ben

[@BuckJolicoeur]

5:14 It's happening fast, but it seems the instability happens when any 3 points leave the circle. When the 3rd point touches the circle, it becomes unstable.

[@persinitrix]

When I play a videogame at it lags just a little bit I get pissed. I can't even comprehend what Mandelbrot felt like
