By Margaret Wertheim – The world is full of mundane, meek, unconscious things materially embodying fiendishly complex pieces of mathematics. How can we make sense of this? I’d like to propose that sea slugs and electrons, and many other modest natural systems, are engaged in what we might call the performance of mathematics.
Rather than thinking about maths, they are doing it.
In the fibers of their beings and the ongoing continuity of their growth and existence they enact mathematical relationships and become mathematicians-by-practice. By looking at nature this way, we are led into a consideration of mathematics itself not through the lens of its representational power but instead as a kind of transaction.
Rather than being a remote abstraction, mathematics can be conceived of as something more like music or dancing; an activity that takes place not so much in the writing down as in the playing out.
Since at least the time of Pythagoras and Plato, there’s been a great deal of discussion in Western philosophy about how we can understand the fact that many physical systems have mathematical representations: the segmented arrangements in sunflowers, pine cones and pineapples (Fibonacci numbers); the curve of nautilus shells, elephant tusks and rams horns (logarithmic spiral); music (harmonic ratios and Fourier transforms); atoms, stars and galaxies, which all now have powerful mathematical descriptors; even the cosmos as a whole, now represented by the equations of general relativity.
The physicist Eugene Wigner has termed this startling fact ‘the unreasonable effectiveness of mathematics’.
Why does the real world actualize maths at all? And so much of it?
Even arcane parts of mathematics, such as abstract algebras and obscure bits of topology often turn out to be manifest somewhere in nature. more> https://goo.gl/ifKV2Z

How to Create a Surreal Photo Collage
By Terri Stone – When you composite photos, you usually don’t want the result to look like a composite. Even if the final scene is fantastical, your aim is to transport viewers into another world. Filip Hodas, a 24-year-old freelance artist from Prague, has been creating convincing digital realities for years. Now he’’ agreed to share his process.
To make the otherworldly landscape featured here, Hodas relied heavily on Adobe Photoshop CC layer masks. He placed each source image on its own layer and then used layer masks to hide and reveal parts of each. He also used layer masks to adjust color and add highlights and shadows.
Next came a Color Balance adjustment layer, which he added to the background images so their colors would be a better match. Trees on the right side of the horizon image were distracting, so he removed them with the Clone Stamp tool.
Hodas knows that small details can have a big impact on a composite’s overall look, so his next step was to refine the foreground image’s mask. That softened jagged edges a little and removed a slight yellow outline. more> https://goo.gl/7jat2c
