MIRRORS. "A real mirror reflection provides a concrete example of this because mirror reflection reverses the space direction perpendicular to the plane of the mirror." https://lnkd.in/eJrXnPM View in LinkedIn

REAL MIRRORS. "The mirror image of a right-handed glove is a left-handed glove. This is in effect a parity transformation (although a true P transformation should reverse all three spatial axes instead of only one)." https://lnkd.in/eJrXnPM View in LinkedIn

NEW THINKING. "Until 1957 it was believed that the laws of physics were invariant under parity transformations and that no physics experiment could show a preference for left-handedness or right-handedness. Inversion, or mirror, symmetry was expected of nature." https://lnkd.in/eJrXnPM View in LinkedIn

NEW THINKING. "It came as some surprise that parity, P, symmetry is broken by the radioactive decay beta decay process." https://lnkd.in/eJrXnPM View in LinkedIn

"WORMHOLES are fascinating cosmological objects that can connect two distant regions of the universe. Based on metamaterials, it could allow electromagnetic wave propagation between two points in space through an invisible tunnel. However, an actual realization has not been possible until now." https://lnkd.in/erp7QhY View in LinkedIn

WORMHOLE CONSTRUCTED. "Here we construct and experimentally demonstrate a magnetostatic wormhole. Using magnetic metamaterials and metasurfaces, our wormhole transfers the magnetic field from one point in space to another through a path that is magnetically undetectable." https://lnkd.in/erp7QhY View in LinkedIn

TUNNEL IN SPACE. "We experimentally show that the magnetic field from a source at one end of the wormhole appears at the other end as an isolated magnetic monopolar field, creating the illusion of a magnetic field propagating through a tunnel outside the 3D space. Practical applications of the results can be envisaged, including medical techniques based on magnetism." https://lnkd.in/erp7QhY View in LinkedIn

FRAGMENT IN NATURE continues again this weekend with the historic changes to both the British countryside, and the British flora and fauna in just fifty years. Unlike countries like America, where there are vast tracts of undeveloped land, Britain's ecosystems are largely cultivated by farmland. Destroy that, and the rest is history. View in LinkedIn

"AGRICULTURE in the United Kingdom uses 71% of the country's land area, employs 1.5% of its workforce (476,000 people) and contributes 0.62% of its gross value added (£9.9 billion). The UK produces less than 60% of the food it eats." The post-war goal of self-sufficiency has not been met, despite the ravaged countryside. https://lnkd.in/ec-KRkc View in LinkedIn
