I do not own these pics. They were sent to me in an email. But I thought I’d share with you all because they’re just AMAZING.
They look like mythical creatures O:

Fractals in Nature
A fractal is a geometric figure that repeats itself on progressively smaller scales, so even if you zoom in an infinite number of times, the pattern will still roughly look like a copy of the whole. Fractals are interesting because they produce irregular shapes that can’t be represented by classical geometry or mathematically described in normal ways. They have the potential to help study galactic clusters, predict natural disasters, create random and organic graphic codes, and understand the movement of chaotic fluids. Fractal patterns also commonly appear in nature, but on a finite scale. They’re found in clouds, mountains, coastlines, snowflakes, crystals, lightning, rivers, cauliflower, and even systems of blood vessels—and by understanding the mathematics that defines them, we can better understand our world.
The Amazing Spider Silk
Spider silk is incredibly strong and flexible, with five times the tensile strength of steel and triple that of the best man-made fibres, but these properties have yet to be replicated artificially—even by fibres produced from pure spider silk proteins. The silk’s protein molecules are long chains consisting of thousands of amino-acid elements, and the interlinking of these chains is how such stable and elastic fibres are created. However, scienctists still don’t understand how the proteins within the silk gland are linked and deployed—they’re thought to have a special storage configuration. Artificially producing spider silk would create enormous engineering possibilities—its ability to sustain selective damage without compromising the entire system could be applied to virtual networks, and its microscopic protein structures could help in stringing together carbon nanotubes. While we’re waiting for science to help us become Spiderman, a group of designers in Austria have created an artistic artificial version of a spider web—made out of 35 km worth of packing tape. The art installation is known as “For Use”, and the cocoons of tape stretched through midair are strong enough for visitors to climb inside and explore—luckily, without becoming ensnared.
