Scientists may have discovered nature's fifth force — dark photons

Scientists may have discovered nature's fifth force
Posted May 26, 2016 19:45:28 Researchers in Hungary have discovered what they think may be the fifth force of nature, which could be a vital clue to understanding dark matter. There are currently four identified forces of nature: gravitational, electromagnetic, strong nuclear, and weak nuclear, but they do not interact with each other in ways that can be explained by the current mathematical model of the universe.

Abkhazia

My favourite is the story of 19th century 'negotiations' between an up-coming Russia and a declining Ottoman Turkey in which Russia demanded the cession by Ottoman -Turkey of the province of Abkhazia. The Turkish delegates who had been summoned to the Czar's palace had little idea of their empire, where Abkhazia was or how big a loss it would represent to Ottoman Turkey. It's actually 8,600 sq kilometers, or 40% of a Wales for those who prefer more traditional area measurements. However there was a map of Abkhazia hanging on the Czar's palace walls, alongside a similarly-sized map of the palace gardens - no scale to either map, although the latter was probably at a somewhat larger scale. Based on these 2 maps the Ottoman delegation concluded they were ceding an insignificant piece of territory.- Dr Hillary Shaw
