The Hardest Mandelbrot Zoom 2017

Opened YouTube tonight and found “The Hardest Mandelbrot Zoom 2017” under recommended viewing. Fractals leapt off the screen (thanks to – admittedly, recognition and comprehension play in different leagues. Mesmerized by the elegance of fractal expansion, I vowed to grasp a foundation of understanding.

Mandelbrot zoom had to wait, instinct demanded clear definition of fractal. Nailing down fractal began with “In mathematics a fractal is an abstract object used to describe and simulate naturally occurring objects”. The key word being “abstract”, as in wrapping your head around a infinite curved line winding through space that appears one dimensional, but in truth harbors a surface defined in fractal dimensions. Further research insisted  “A regular line is conventionally understood to be 1-dimensional; if such a curve is divided into pieces each 1/3 the length of the original, there are always 3 equal pieces. In contrast, consider the Koch snowflake. It is also 1-dimensional for the same reason as the ordinary line, but it has, in addition, a fractal dimension greater than 1 because of how its detail can be measured. The fractal curve divided into parts 1/3 the length of the original line becomes 4 pieces rearranged to repeat the original detail, and this unusual relationship is the basis of its fractal dimension”.

Defining fractal called for a simple analogy, I found this – “imagine that you were to measure the trunk of a tree. We humans look at it at the largest scale let’s say that you wrapped a measuring tape around it. That tape would give you a decent estimate, let’s say 1 meter, but it wouldn’t be getting all the little bumps and crevices. If you were to have, say, a beetle crawling along the surface of the trunk, it would be going up and down those bumps, so it would measure a longer distance, maybe 3 meters. But even that beetle would just be walking over tiny little slits in the bark that are too small for it. If you had something even smaller (an extraordinarily tiny insect, for example), it would have to go up and down even more, and it could measure the distance around the tree at huge numbers, such as 100 meters. And this can continue for a long time, getting smaller and smaller, but seeing basically the same thing at each level, just a lot more of it. Of course, this breaks down when you get too small, since everything is composed of atoms, but for the scales where life occurs, tree trunks are actually fractal in nature.”

Back to YouTube’s recommended viewing of the Mandelbrot Zoom – according to Wikipedia the Mandelbrot set is a nod to mathematician Benoit Mandelbrot who coined the term fractal when he theorized mathematical definition of roughness and self-similarity in nature. Confused? Shake it off and immerse yourself in this clip. It doesn’t matter if it makes sense, all that matters is willingness to accept it exists. For those who need hard facts over abstract wonder, some links –

Enough talk, sit back and watch the hardest Mandelbrot zoom …
