There is not much that Mandelbrot has done or seen that can be undone or unseen. For that I thank him immensely

As a freshman math major, I did an independent project on fractals. I wrote to Mandelbrot himself, and he called me on the phone in my college dorm room. And mailed me a package of very interesting preprints on the Mandelbrot set.

awww. Benoît Mandelbrot is someone I deeply admire.

Interview with Benoit Mandelbrot l TED talk, Benoit Mandelbrot: Fractals and the art of roughness

On a weekend afternoon in the mid-1980's I wandered into one of those IBM exhibits on east 57th Street, on the ground floor of their main building here in NYC. There were a few small videos showing a short biography of Mandelbrot, the surface of a landscape, cauliflower, wind ruffled water, how no geometry before had properly described those rough surfaces, how they are predictably unpredictable. There were several interactive displays, which allowed a person to pick a design and create their own Mandelbrot fractal design.

That there was a geometry for this, the poetry of textures filled my being. He'd articulated complexity. Without really understanding why I felt both relieved and full of joy. Ahh, increments and iteration. In Mandelbrot's own words, "fractals had been pictured forever but their true role had remained unrecognized and waited for me to be uncovered."

"I conceived, developed and applied in many areas a new geometry of nature, which finds order in chaotic shapes and processes. It grew without a name until 1975, when I coined a new word to denote it, fractal geometry, from the Latin word for irregular and broken up, fractus. Today you might say that, until fractal geometry became organized, my life had followed a fractal orbit."

A likable biography l virtual books by and about Mandelbrot l Scientific American article about Who Discovered the Mandelbrot Set ? l the Mandelbrot Set l The Spanky Fractal Database

"The beauty of geometry is that it is a language of extraordinary subtlety that serves many purposes."

My condolences to his wife, Aliette, to his friends and relatives.

For a time, I worked down the hall from Dr. Mandelbrot's office.

He would occasionally sit with us for lunch. I both dreaded and eagerly anticipated those days.

I dreaded them because, well, how do you make small talk or discuss your research with someone like him? Someone who was at the IAS during its peak, who collaborated with John von Neumann and walked the halls with Einstein? Whose contributions burst out of the confines of mathematics and found expression in economics, cosmology, and nature?

And indeed, we didn't have much of a conversation. He mostly talked about himself, and the people he's known, and told stories about everything from the war to the first time he used email. Which made sense, since he'd lived an epic life, and was in that period where all men, famous and obscure, are in a reflective mood.

It was fascinating. But it was also kind of annoying. How do you chat with your colleagues about your current research when it seems so trivial compared to, well, running from the Nazis and inventing fractals? His presence immediately overshadowed everyone at the table, and we became polite, respectful, and very silent while he spoke.

And yet, I very much wanted to have a real discussion with him, to talk to him about my work and what I believed the implications could be. Dr. Mandelbrot represented the kind of researcher that I always dreamed of being: a man whose deep passion for his subject was spurred by an appreciation for all the ways in which it could be relevant to the world at large, and whose work reverberated across a dozen fields.

But a vast gulf separated us; our fields were radically different, as were our ages, our fame, our experiences and our accomplishments. Not to mention our egos and our intellects. All we really shared was a hallway.

After a while, he stopped sitting with us for lunch. I wondered if he was disappointed in us. Disappointed with our awe in his presence, our lack of achievement in comparison to his own, and yes, our mild irritation at having to eat lunch with a Famous Person every day.

For my part, I greatly regret never doing more to attempt to bridge that gap. I wish I had been brave enough to ask the stupid questions, to risk his boredom or indifference, to laboriously explain why I thought my area of research (which I had heard him dismiss offhand before) was fascinating and worthy of attention. And to give him the opportunity to tell yet more stories.

The true importance of Mandelbrot's work lies outside of science. You will occasionally meet the math or physics wonk who will argue at length that fractals aren't all that useful. To which I always reply, they have been very useful to me as the answer to the still oft-encountered question, "If God isn't the reason the universe looks the way it does, what is?"

The true importance of Mandelbrot's work lies outside of science. You will occasionally meet the math or physics wonk who will argue at length that fractals aren't all that useful.

They should remember that in the 19th century, several objects that we'd now recognize as fractals played a pivotal role as counterexamples in math, helping to clarify the nature of the real numbers. For example, Weierstrass's everywhere continuous / nowhere differentiable function, the Cantor set, and the Dirichlet ruler function.

Anyway, maybe Mandelbrot won't be remembered for proving theorems, but he was hugely important to science as a popularizer. How many thousands now in science, math, and engineering were inspired by the beauty of the Mandelbrot set when they were young?

A couple of neat points I remember from my freshman project on fractals and the Mandelbrot set:

1) The proof that if Z iterates to a modulus of 2, then its iterates will be unbound was within my freshman ability, though trickier than I expected.

2) The recurring circle spiked with circles shape in the Mandelbrot set has an analytic expression (only approximate I assume other than perhaps for the shape on the real axis). Start with a circle. Add circles on its circumference at angles 2 pi (j/k) radians. Assume j/k is in lowest terms; then make the radius of the added circle (1/k)2 of the original circle. (For example, you have a circle at 180 degrees with 1/4 the radius of the starting circle, circles at 120 and 240 degrees have radii of 1/9, etc.) I think the denominator k was related somehow to the associated Julia set within the circle or cycles of iterates of Z.

There was much more to fractals than the Mandelbrot set of course. "Similarity dimension" was simple enough to explain to friends (instead of the more rigorous "Hausdorf dimension").

My lady wears a string of invisible pearls
It homes toward the center

And at the upside down apex of this
Catenary (or wind-blown bubble)
Near to her heart
(Approximately)
Rests a pearl.
