"Not a shred of evidence exists in favour of the idea that life is serious" - Brendan Gill
• How Mandelbrot’s Fractals Changed The World

by Jack Challoner/BBC News

During the 1980s, people became familiar with fractals through those weird, colorful patterns made by computers. But few realize how the idea of fractals has revolutionized our understanding of the world, and how many fractal-based systems we depend upon.

Unfortunately, there is no definition of fractals that is both simple and accurate. Like so many things in modern science and mathematics, discussions of “fractal geometry” can quickly go over the heads of the non-mathematically-minded. This is a real shame, because there is profound beauty and power in the idea of fractals.

The best way to get a feeling for what fractals are is to consider some examples. Clouds, mountains, coastlines, cauliflowers and ferns are all natural fractals. These shapes have something in common - something intuitive, accessible and aesthetic.

They are all complicated and irregular: the sort of shape that mathematicians used to shy away from in favor of regular ones, like spheres, which they could tame with equations.

Mandelbrot famously wrote: “Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line.”

The chaos and irregularity of the world - Mandelbrot referred to it as “roughness” - is something to be celebrated. It would be a shame if clouds really were spheres, and mountains cones.

Look closely at a fractal, and you will find that the complexity is still present at a smaller scale. A small cloud is strikingly similar to the whole thing. A pine tree is composed of branches that are composed of branches - which in turn are composed of branches.

This is one of the greatest things I’ve ever read. P.S. I miss irregularity.

ANTIQUATE

[verb]

1. to make obsolete or old-fashioned.

2. to give an old or antique appearance to.

Etymology: from Mediaeval Latin antīquātus, “old, ancient”, past participle of antiquāre, “to make old”.

There are elements of the ageing process which are in no way enjoyable, others I would consider as invaluable.  Experience after experience; I can’t quite get my head around which direction terra firma is orientating my vector.

Wasting, waiting, wanting; hope, honour and hospitality. There is no easy way in or out.

I’m glad I didn’t post that.

• ## Luckily astrobiology doesn’t intersect politics too much.

I guess this is a plus, thanks Prof David Catling.

Would politics be put on hold if they found some space microbes?  Would anybody care?  Have they found any already?   I’m not suggesting any Independence Day carry on, just a few cyanobacteria scattered about an astroids trail.

Astrobiota for peace!

The app race is on.
Watch this, yer man knows his stuff.

FORTITUDE

[noun]

mental and emotional strength in facing difficulty, adversity, danger, or temptation courageously.
