Oh My Guardian #4

• The past 16 years have involved a lot of questioning and reflecting, both in terms of what it means to be “good”, but also on the various racist myths about Muslims. — Let’s be clear: Muslims are neither good nor bad. We’re just human, Farah in terms of Elahi, The Guardian, 14/xii/2017.

This is an L-triomino, or shape created from three squares laid edge-to-edge:

When you divide each square like this…

You can create a fractal like this…

Bats and Butterflies

I’ve used butterfly-images to create fractals. Now I’ve found a butterfly-image in a fractal. The exciting story begins with a triabolo, or shape created from three isoceles right triangles:


The triabolo is a rep-tile, or shape that can be divided into smaller copies of itself:


In this case, it’s a rep-9 rep-tile, divisible into nine smaller copies of itself. And each copy can be divided in turn:


But what happens when you sub-divide, then discard copies? A fractal happens:

That’s a simple example; here is a more complex one:

Fractal butterflies #3


Fractal butterflies #4


Fractal butterflies #5

Some of the gaps in the fractal look like butterflies (or maybe large moths). And each butterfly is escorted by four smaller butterflies. Another fractal has gaps that look like bats escorted by smaller bats:

Noise from Nowhere

• Es war, als ob er irgendwohin horchte, auf irgend ein unheimliches Geräusch. — Thomas Mann, Der kleine Herr Friedemann (1897)

• He seemed somehow to be listening, listening to some uncanny noise from nowhere. — “Little Herr Friedemann” (translated by David Luke)

Holey Trimmetry

Symmetry arising from symmetry isn’t surprising. But what about symmetry arising from asymmetry? You can find both among the rep-tiles, which are geometrical shapes that can be completely replaced by smaller copies of themselves. A square is a symmetrical rep-tile. It can be replaced by nine smaller copies of itself:

Rep-9 Square

If you trim the copies so that only five are left, you have a symmetrical seed for a symmetrical fractal:

If you trim the copies so that six are left, you have another symmetrical seed for a symmetrical fractal:

Now here’s an asymmetrical rep-tile, a nonomino or shape created from nine squares joined edge-to-edge:

Nonomino


It can be divided into twelve smaller copies of itself, like this:

If you trim the copies so that only five are left, you have an asymmetrical seed for a familiar symmetrical fractal:
