I don't know about you, but i've thought to be a completely like was to be someone who could fit in anywhere, adapt in. Turns out that is all wrong. Millions don't change color to match their environment. In fact, it's just the opposite. Their baseline is camel lush. When coming, lions are relaxed. They're mostly Green. They are naturally blended to their home in the forest canopy. They even mimic leaves by dancing around the little. But when they feel threatened or annoyed or just want to show a little swagger, that is, when their color or changes, they transform into living, murdering millions change color and make a statement. The faster their skin changes color to them, more excited they are. How do they do this? Well, IT turns out we've been getting that wrong, too, until this year. Scientists, that millions change color by spreading out pigments and their cells like the skin of the squid, seeing right here. But the truth is way more complex. Just below the surface of their skin is a layer of cells called your ride. Force v cells contain tiny nano scale salt Crystals. They're only one hundred and thirty anomalies across that's less than one hundred the th of a human hair. The Crystals are arranged in a three dimensional s. When light hits, the light IT shares into different wavelength. Some are absorbed and some bounce back. The result, our eyes appears Green or red or blue. The wings of the morph butterfly have similar structures which reflect briled blue hues. But unlike morpho butterflies, communities can stretch or contract the let us, which moves the distance between Crystals. Each of these points of light is an array of Crystals. When the distance changes, the crustal reflect a different wavelengths of light. The result is a dramatic shift in color. So what if we could come up with some kind of material that could change from one brilliant color to another electrical engineers that U. C. Berkeley are trying to do that to mimic AA millions structural color control with synthetic materials. They arranged tiny nano scale silicon ribbons on a sheet of flexible plastic. Each one of these pixels is made up of about one hundred and sixty ribbons. When the plastic stretches, the space between the ribbons becomes greater, and a different wavelength of light is reflected just like a million skin. Well, almost. This synthetic common skin has just one layer of nano scale, a race. The socrat stals in real communion skin are stacked in several layers, which makes the skin some of the most colorful and complex in the animal kingdom. They produce colors that aren't even visible to human eyes. What I like about millions is they show us how wrong we can be about science. What we call camelina is an entire language as million to asses the clicks of a dolphin or the low rumble of an elephant, a visual language made of colors we can only begin to imitate and imagine. Tippy and her animal friends. hi, i'm tippy. Look, this is my book. This is Linda. SHE is an old street. SHE is fast. This is leon. He is a celine, 意思吗？ They are my animal friends. I love them.
