A BAFFLING video which appears to show a mug to be both round and square has taken the internet by storm. It's the work of Tony Fisher, who runs his own YouTube channel, creating puzzles. In the video the mug - which Tony proves is genuine by filling up with milk - seemingly appears to be two different shapes. When looked at in a mirror it is square but from another angle it is round. But it's not witchcraft - it's physics. Tony wrote: "The milk and spoon were used to show there was no video trickery. Milk shows up better than other liquids in the gold mug. The mug is based on a shape devised by Kokichi Sugihara." We've previously reported how Mr Sugihari uses a type of science called anomalous symmetry to create illusions. This is when illusions appear to break the laws of optical physics by forcing mirrors to reflect what appears to be the opposite of what would normally be reflected - therefore tricking our eyes into seeing something different. He demonstrated in May how it … [Read more...] about Is this mug round or square? Optical illusion has people baffled

A major incident has been declared in Wiltshire after it was suspected two people might have been exposed to an unknown substance in Amesbury.The man and woman, both in their 40s, are in a critical condition at Salisbury District Hospital, Wiltshire Police said.The force said it was not clear if a crime had been committed, although a number of scenes in the Amesbury and Salisbury area have been cordoned off as a precaution.The pair were found unconscious at an address in Muggleton Road on Saturday evening and it was initially believed that they may have taken illegal drugs.-policeCounter-terrorism teams from Scotland Yard were called in to lead the investigation when Wiltshire Police was faced with the poisoning of former Russian spy Sergei Skripal and his daughter Yulia.On Wednesday morning Scotland Yard was referring media calls to Wiltshire Police.On Muggleton Road, where the man and woman were found, there was one police officer on duty outside a block of newly-built flats.The road … [Read more...] about Cobra committee meeting called after couple exposed to same nerve agent as Sergei Skripal

PEOPLE are baffled by a spinning arrow which seemingly always points right - but it is just a trick of the mind. Thousands of people have shared a video of the trick online, with folk perplexed as to how the arrow can always been pointing in the same direction. But, cleverly, it is just an optical illusion - invented by Kokichi Sugihara from Meiji University in Japan. Mr Sugihara built the white arrow, knowing its duplicitous effects could only be seen by viewing the arrow from above. On the Instagram page where the trick was first revealed, it says: "Spin this arrow 180 degrees and it still points to the right - only in a mirror will it point left, and only to the left. "A clever combination of reflection, perspective, and viewing angle produce this striking illusion." A video of the arrow only reveals how it works at the end, when it shows it against a mirror. And, in the later part of the video, the arrow is bent upwards, revealing its real shape - which is an oblong with … [Read more...] about Baffling optical illusion leaves people scratching their heads – why does this arrow ALWAYS point right?
According to the popular view of the Earth's formation, about one billion years ago, our planet's molten liquid inner core spontaneously began to crystallise, growing rapidly to the extent that it reaches today – around 760 miles in diameter. However, a new study published in the journal Earth and Planetary Science Letters contradicts this theory, suggesting it is impossible. Researchers from Case Western Reserve University in Ohio argue that the standard narrative is overlooking a key detail of how crystals form, namely, that they require a huge drop in temperature that is unlikely to have happened inside the core. In fact, once this is taken into account, the team suggest that the Earth's inner core shouldn't exist at all. "Everyone, ourselves included, seemed to be missing this big problem, that metals don't start crystallising instantly unless something is there that lowers the energy barrier a lot," said author Steven Hauck, a professor of Earth, Environmental and Planetary … [Read more...] about Formation of the Earth’s inner core is so baffling, scientists say it shouldn’t exist
