Photonic Crystals in Nature
Living organisms on Earth are under constant pressure to compete for resources, a fight that has, over billions of years and countless generations, given rise to the amazing diversity of life we see around us. From microscopic aquatic bacteria to thousand-year old groves of trees, living things have acquired characteristics that uniquely allow them to survive even in the most difficult environments on the planet. Among these characteristics is the natural appearance that can help living organisms avoid predators, attract mates, and acquire resources. Found in the feathers of peacocks, the camouflage of chameleons, and the wings of butterflies is a special trait that grants them their extravagant and dynamic coloration. Nanoscale features interact with the light falling on these animals in a dazzling display of the ingenuity of nature. Known as photonic crystals, studying how these features are created and how they are used in nature could inspire novel technologies for optical computing and data transfer, fabrics and coatings, and photovoltaic energy harvesting.

Between 1970 and present, global production of plastic has grown tenfold, faster than any other mass-produced material. This revolution has been fuelled by mankind’s demand for cheap, lightweight and strong materials used in industry, transportation, science, and consumer products. Plastics are ubiquitous in our everyday lives, from simple things like food packaging to items that often go unnot...

Living organisms on Earth are driven to compete for resources, to adapt to their environments, and to pass on their adaptations to future generations. The course of this process has resulted in the incredible variety of life we see around us, from microscopic bacteria in hydrothermal springs to colossal aquatic mammals, and has given certain species extraordinary abilities. Among those abilitie...

The vibrant tropical rainforests of central South America are a diverse environment home to countless extraordinary plant and animal species; however, despite the visible abundance of the forest canopy, the soil beneath the trees is often severely depleted of organic matter.

The constant transformation and flux of water across the surface of the Earth has been responsible for ...
Levinthal's Paradox, Protein Folding and AlphaFold

Around five decades ago, Cyrus Levinthal, an American molecular biologist, postulated that if a protein were to sample every possible conformation of its amino acids, it would take longer than the age of the universe to assemble into its three-dimensional shape. Although scientists had been studying proteins for decades prior, the mystery of how proteins could reliably fold into their conformat...

    your definition of fractals at :30 is wrong btw. What fractal means (as defined by Benoit Mandlebrot, the creator of the word fractal) is a pattern that gives more information the closer you zoom into it. The simplest example i can give is a river on a map. When zoomed out its just a blue line but when you zoom in you see more complex iterations of the river. Some fractals, like the mandlebrot set, have self similarities when you zoom in, but thats just a facet of certain fractal sets, not what fractals truly are.

    I think it's an over statement that after 50 years, AI helped us "understand how proteins fold" and does it computationally. What it actually does, it looked into classified information specified by humans, (for eg. this is how a good protein of type x looks like and this is how a protein of type y should look like) and then it can predict based on what information it has (with a machine learning system), but I don't see how is this related to the paradox or with our understanding about how the protein formed in the first place...!? Am I missing something?

    Stephen Harrod Buhner's book "Secret Teachings of Plants" expands this richly. In this video you have presented fractals in a very linear way. That's OK as an interface, but it misses the point that fractals lead us, naturally to systems thinking. The worlds comprehensible to systems thinking are ones in which linear thinking no longer functions. They can expand our objective world view to include the methodology of living-nature that has been a mystery to science until now.

    Healing is a specific biological process. I'd rather refer to the process where plastics repair themselves as repairing, restoring, or renovate, no?

      The vascular healing method was actually inspired by biological healing mechanisms, for what that's worth.

  • @justanotherguy3018
    @justanotherguy3018 Před 8 měsíci

    Seems like with both intrinsic and extrinsic mechanisms the healing is still quite slow compared to the possible speed of the defect propagation, how would we go about making it heal faster especially for the instrinsic mechanisms? These might be effective against fatigue but definitely wouldn't do too well against a catastrophic failure.

  • @zenasm.savage1999
    @zenasm.savage1999 Před 8 měsíci

    Ideally, you'd want some kind of multiphase polymer that had the desired healing reagent's in a colloidial suspension within the polymer itself. The activation energy of the healing reaction should be as low as possible so that the reaction spontanous completes and/or reverses at service temperature of the polymer. In this situation the reagents would need to be a catalyst so that the healing ability did not diminish over time-- in other words the healing reaction takes place constantianly through out the solution and then the reagent catalyst is somehow transported or able to diffuse to another site requiring repair within the polymer. Basically the lowest we can make the activation today is the energy required to break a microcapsule and even then its not reversible in a controlled manner.

    Many but clearly not all fractals are self similar in some aspect. Mathematically not necessarily self similar but part exponential or a fraction of the usual integer exp hence “fractal”. Highly conserved in nature because of symmetries rather than (self) similarities per se

If anyone has taken large amounts of LSD-25, psilocybin, mescaline, or DMT AND you have seen the red and blue light fractal-ed by a singing bowl or an icosahedron, then hit me up. We got some time and space to fractal in and out of. Gee whizz, i wonder why CZcams think psilocybin, icosahedron, and adrenochrome ARE ALL MISSPELLED WORDS even though i spelt all 3 correctly.
