PREAMBLE. We embark now on selected themes about symmetry and how this relates to programmability in nature and in artificial systems. Nature has a lot to teach technologists about the virtues of anisotrophy, and of symmetry breaking. The fascinating subject of symmetry is at the heart of modern physics and also modern biology.

FRAGMENT IN NATURE this weekend, and for at least next weekend, will focus on the connection between the microbiome, taste, satiety and health. Given that taste receptors around the body are key to satiety and diet selection, it seems likely that the microbiome would have evolved to play a role in controlling that system. View in LinkedIn

SOME BEETLES have naturally occurring photonic gaps that account for their brilliantly green colored carapaces. They are made of liquid crystalline microstructures. https://lnkd.in/eAb2xSi View in LinkedIn

DOPED CRYSTALS. "The perfect semiconductor crystal is quite elegant and beautiful, but it becomes ever more useful when it is doped. Likewise the perfect photonic crystal can become of even greater value when a defect is introduced." https://lnkd.in/eGCJ-37 View in LinkedIn

PHOTONIC CRYSTALS. "In this paper we pursue the rather appealing analogy between the behavior of electromagnetic waves in artificial, three-dimensionally periodic, dielectric structures and the rather more familiar behavior of electron waves in natural crystals. These artificial two- and three-dimensionally periodic structures we call photonic crystals." https://lnkd.in/eGCJ-37 View in LinkedIn

QUASICRYSTALS. "Crystal with "forbidden symmetry" found in 4.5 billion-year-old meteorite." These rare quasicrystals are somewhere between crystals and random states. http://www.iflscience.com/space/crystal-forbidden-symmetry-found-45-billion-year-old-meteorite View in LinkedIn

LIGHT TRUMPS ELECTRONS. "Scientists are mow turning to light instead of electrons as the information carrier. Light has several advantages over the electron," including traveling faster, carrying more information, having a larger bandwidth, and having lower energy losses. https://lnkd.in/ePpnEbv View in LinkedIn

THE PHOTONIC GAP. "Photonic crystals are materials patterned with a periodicity in dielectric constant, which can create a range of 'forbidden' frequencies called a photonic gap. Photons with energies lying in the bandwidth cannot propagate through the medium. This provides the opportunity to shape and mould the flow of light for photonic information technology." https://lnkd.in/ePpnEbv View in LinkedIn
