Unhappy Benoît Mandelbrot is dead :-(

Hi guys,

I'm feeling a little depressed at the moment...

How many people tried with how many tools on their Miggies to get this fractal stuff calculated? 1000's? 100000's?
And how many HOURS did this take on a stock A2000 sometimes?
See, that's why I thought putting this into the OT section would be a bit of a bad idea...

Well, after an OUTSTANDING talk on TED in February 2010 (audience giving standing ovations and all), cancer has now managed to get the better of this both nice and modest individual.

R.I.P., genius.

Alas!

I met him at a congress in Lausanne, Switzerland, several years ago.
And most of my scientific articles concern Bethe lattices, a kind of fractals.

R.I.P., dear Benoit!

Yep, that's really sad news. I used to mess around a lot with fractals a lot on my old A500

Just had a quick look at his bio on wikipedia, and there's some beautiful examples of the Mandelbrot set on there. Visual mathematics.

Sad news indeed.

The name Benoît Mandelbrot is almost synonymous with fractals.

His surname certainly is.

When most people think of a Mandelbrot set, what comes to mind are the beautiful colour visualisations generated by computers from the 8-bits to today.
In reality, the concept of a Mandelbrot set is an extraordinarily complex abstract mathematical notion, the very existence of which shook the foundations of modern mathematics.

For more on the mathematics on fractals and Chaos theory, I recommend the book "Does God Play Dice?" by Ian Stewart. (The title is a reference to an Albert Einstein quote.)
This book is on the recommended reading list for my university's mathematics undergraduate students, but is accessible enough for those with little mathematical background.

On the subject of Mandelbrot fractals, if you enjoyed creating them on your Miggy back in the day, then check out some of the fractal generators on modern PCs.
The ability to zoom into high-definition true-colour Mandelbrot fractals in real time with a smooth framerate is quite an advancement over the Amiga 500 or 2000!

Still, Amiga helped pave the way for the wonders of modern computing:

Very sad news. He taught us both insight and beauty.

Very sad news indeed.

I managed to create a few Mandelbrot's in AMOS Basic a while back. I have no clue how to do it in assembler. Elena Novaretti is defintely the master (other than Mandelbrot himself).

AMOS Basic had an extension package called CRAFT which, among other features, included a highly optimised Mandelbrot fractal generator written in 68k assembler.
Much, much faster than coding it in BASIC (source for doing that was included too).

I could even do a small amount of real-time zooming on an A1200 (if the resolution was low enough).

I'm sure I had a fractal program on the Amiga, maybe it came on a coverdisk...

Mand2000 by Cygnus Software was probably the fastest and most popular fractal explorer on the Amiga.

Wow... this is quite sad news indeed... I discovered Fractals as early as 1.5 years ago, and really got into them for a while.

So much that the mathematical concepts fueled some ideas for comics that I've got cookin'.

Man... I kind of wanted to hear what he thought about my theory for a Multiverse level 4 Fractal-geometry dominant Universe. ( the idea is that although our own Universe's geometry is fundamentally based on fractal geometry, there are other geometries visible as well, such as simple ones. But what if the laws of nature are changed, so that the fractal geometries become completely dominant? Structures such as atoms then change radically, or cease to exist!)

I also just read that he himself had done some ponderings on multiversal theory... wow.. too late did I find this out.

May his legacy never be forgotten or trivialized. Here's to Benoit Mandelbrot. Your work will always be an inspiration to me.

Let's not forget the "Screaming Mandy" from Llamatron



I wonder if he realised he had an Amiga 'baddie' named after him?

R.I.P. Benoît B Mandelbrot

as previously posted in OT (i cant say i checked very thoroughly for a non-OT thread!)...


http://www.guardian.co.uk/artanddesi...t-geometry-art

Just wishing to pay respects to a man who showed us the beauty of mathematics - with his work no-doubt remembered by demosceners and llamatron fans alike.

In tribute to Prof Mandelbrot, I've just uploaded to YouTube a video of a unfinished demo that I made in 1994 for the A500: [ Show youtube player ]

It features a 26 second long Mandelbrot zoom.

A clever bloke indeed.

Coincidentally I'm just reading Jurassic Park, which features fractal images inbetween each chapter (as well as mentioning fractals and Mandelbrot in the story).

RIP.

I found something amazing about Mandelbrot set. 3D visualisation. http://www.skytopia.com/project/frac...b.html#renders

Now that looks cool/awesome/scary/weird.

Good find!

I probably wouldn't have known the man if it wasn't for Amiga. All of a sudden every demo group did fractals
