GOVERNMENT PRICE SUPPORT. "The landscape, especially in eastern England, was reshaped from the traditional patchwork-quilt of small to medium-sized fields variegated with their hedges and woods and quirky corners, to vast ovaries of wheat and barley, Kansas-style." https://lnkd.in/esig3Kt View in LinkedIn

NEXT WEEKEND the shocking theme of the changes in British flora and fauna continues. I have been visiting Paris and the countryside northwest of the city, and my impression is that the situation here is even more grave, with gigantic monoculture fields and marginalized woodlands. I head now for Catalonia, with its generous forests, crop rotation with alfalfa, and great strips of wild bamboo. View in LinkedIn

FROM ELECTRONS TO PHOTONS. "Being able to control photons so precisely could have a great effect on the technological landscape of the world. When the ability to control electrons with magnetism was discovered it eventually resulted in modern electronics." https://lnkd.in/egWQir9 View in LinkedIn

PHOTONIC CRYSTALS. "This technology is built upon recent research into photonic crystals, which are crystals that can ‘trap’ and release photons." https://lnkd.in/egWQir9 View in LinkedIn

PHOTONIC CRYSTALS. "To create the device, the researchers made “a grid of tiny cavities etched in silicon, forming the photonic crystal. By precisely applying electric current to the grid they can control — or ‘harmonically tune'...the photonic crystal to synthesize magnetism and exert virtual force upon photons." https://lnkd.in/egWQir9 View in LinkedIn

PHOTONS TRUMP ELECTRONS. “The new device, therefore, solves at least one major drawback of current photonic systems that use fiber optic cables. Photons tend to reverse course in such systems, causing a form of reflective noise known as backscatter." https://lnkd.in/egWQir9 View in LinkedIn

PHOTONS TRUMP ELECTRONS. “Our system is a clear direction toward demonstrating on-chip applications of a new type of light-based communication device that solves a number of existing challenges." https://lnkd.in/egWQir9 View in LinkedIn

ARTIFICIAL MAGNETISM. "In 1999, several artificial materials were introduced, based on conducting elements designed to provide a magnetic response at microwave and lower frequencies." https://lnkd.in/ewjS99N View in LinkedIn

ARTIFICIAL MAGNETISM. "These nonmagnetic structures consisted of arrays of wire loops in which an external applied magnetic field could induce a current, thus producing an effective magnetic response." https://lnkd.in/ewjS99N View in LinkedIn

INDUCED MAGNETISM. "The possibility of magnetism without inherently magnetic materials turns out to be a natural match for magnetic resonance imaging (MRI), which we use as an example of a potential application area for metamaterials." https://lnkd.in/ewjS99N View in LinkedIn
