Escher for Real The work of M.C. Escher needs no introduction. We have all learned to appreciate the impossibilities that this master of illusion's artwork presents to the layman's eye. You are also invited to watch our movie: "Escher for Real" and "Impossibly Real". "Escher for Real" "Impossibly Real" Convention In the following sequences, figures are frequently presented in pairs. The Penrose Triangle We start with the Penrose triangle object (also independently invented by Oscar Reutersvard). The Penrose Rectangle The impossible shape conveyed by the Penrose triangle is the most well-known one. The Penrose Pentagon Similarly and following the construction of a Penrose triangle and Penrose rectangle, one can easily create an arbitrary Penrose n-gon. The Penrose Triangle II Here we present another way to simulate and realize geometry that looks like the Penrose triangle from a certain view. The Penrose Triangle IV Escher's (Louis Albert Necker's) Cube Here is our realizable variant of Escher's/Necker's Cube.

(Update: Discovery News is now unsure if the story is real and wondering if they were duped. It reminds us of this "Yes Men" poop burger hoax.) Take a moment to let that gag reflex subside. The steaks were first envisioned by Japanese researcher Mitsuyuki Ikeda after he was approached by Tokyo Sewage to come up with a solution for the city's overabundance of sewage mud. After isolating those proteins in the lab, Ikeda's team then combined them with a reaction enhancer and put them in an exploder. "Theoretically, there's nothing wrong with this," said Douglas Powell, a professor of food safety at Kansas State University. The official composition of the lab-grown steak is 63 percent proteins, 25 percent carbohydrates, 3 percent lipids, and 9 percent minerals.
UK | England | Carvings riddle stumps villagers Puzzled residents across Yorkshire are turning detective after mysterious stone heads were left outside their properties in the dead of night. The sculptures feature the same carved symbol and come with a riddle attached. Despite CCTV film showing a man leaving three heads outside a post office, their origin remains unknown. So far, 12 have appeared in Goathland and Kilburn, North Yorkshire; four in Arthington, West Yorkshire and three in Braithwell in South Yorkshire. Each of the heads, which are up to a foot tall, looks different but all feature the same carving - which appears to spell out the word "paradox" - and a note bearing the riddle: "Twinkle twinkle like a star does love blaze less from afar?" The villages they have been found in are up to 50 miles from each other. Mike and Valerie Hoyes, who run a post office in Braithwell, found three heads outside their business on the morning of 23 August. Mrs Hoyes said: "It's very weird. Stonemasons quizzed
