"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

STATE OF DECLINE. "The State of the UK's Birds report...shows that of the UK's 107 most widespread and common breeding birds, 16 species have declined by more than a third since 1995, including the willow tit, starling, cuckoo, lapwing and wood warbler." https://lnkd.in/eV5Cr3a 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

LESS BIRDS AND BEES. "All across the land, they tumbled in numbers, the birds, the wild flowers, the butterflies, and it is clear that more than half of all Britain's wildlife, as it existed at the end of the Second World War, has now gone." https://lnkd.in/esig3Kt 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

DECLINES. "It is exactly the same story with butterflies. There have been only three national extinctions in the post-war years..but since the butterfly recording schemes first started, nearly three-quarters of our fifty-eight remaining species have declined and disappeared over much of the country" (52-79%). https://lnkd.in/esig3Kt 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

NATIONAL VS LOCAL EXTINCTIONS. "During the whole of the twentieth century, there were about twelve national extinctions amount Britain's fifteen hundred or so native plants. But on a county-by county basis, 66-93 species of plants were gone entirely." https://lnkd.in/esig3Kt View in LinkedIn

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

LOCAL EXTINCTIONS. "The number of birds which have declined so much as to be locally extinct...1967-2011, the turtle dove declined in Britain by 95%, the grey partridge by 91%, the spotted flycatcher by 88%, the yellow wagtail by 73%...the tree sparrow by 95%; and so it goes on. In most of the country, they've simply vanished." https://lnkd.in/esig3Kt View in LinkedIn
