## Let’s Begin…

A bump on the head, a mysterious femme fatale and a strange encounter on a windswept peak all add up to a heck of a night for Manny Brot, Private Eye. Watch as he tries his hand at saving the dame and getting the cash! Shudder at the mind-bending geometric riddles! Thrill to the stunning solution of The Case of the Missing Fractals.

The word “fractal” was coined by Benoit Mandelbrot (namesake of both the Mandelbrot set and a certain hard-nosed private eye) in 1975. Mandelbrot was not the first mathematician to examine these perplexing shapes, but he launched the formal study of them as a scientific tool to understand complexities found in nature. His book, The Fractal Geometry of Nature paved the way in this regard.

A more complete definition of fractals than the one found in this video is:
- Fractals are generated through iteration (repeating the same operation infinitely)
- Fractals display self similarity (they’re repeat the same patterns no matter how much you zoom in)
- Fractals have fractional Hausdorff dimension. Essentially, this means that they’re rougher than platonic solids—more jagged and with fewer smooth, predictable curves. If you were to walk through a thicket of fractals, they’d stick to your clothes a lot more than spheres and cubes would.
This Wikipedia page lists quite a few fractals in increasing order of Hausdorff dimension.
Imagine a two-dimensional world -- you, your friends, everything is 2D. In his 1884 novella, Edwin Abbott invented this world and called it Flatland. Alex Rosenthal and George Zaidan take the premise of Flatland one dimension further, imploring us to consider how we would see dimensions different from our own and why the exploration just may be worth it.
