The Fangweng Restaurant

The Fangweng Restaurant in Hubei Province, China, is located conveniently near the popular Sanyou Cave tourist destination. But what may strike you as more impressive is that the eatery appears to hang on the side of a cliff! If you didn’t know this ahead of time, you might be surprised, because the entrance gives no clue. You must walk down a passageway that juts out over the Happy Valley of the Xiling Gorge to get to the dining hall. Once there, most of the tables are safely inside a cave, with just a few on a ledge over the chasm. Read about this restaurant and see more pictures at Spot Cool Stuff.

7 Weird and Wonderful Facts About the Wizard of Oz Books

The new movie Oz the Great and Powerful opens today in theaters nationwide. The backstory of the wizard is loosely based on the L. Frank Baum book The Wonderful Wizard of Oz . Baum went on to write 14 more books about Oz, because the public kept demanding more. An interesting fact I didn’t know -one of his granddaughters was named after an Oz character!   Baum had a granddaughter named “Ozma,” and his 11th Oz book, The Lost Princess of Oz (published 1917), was dedicated to her shortly after her birth. The story begins with the disappearance of Princess Ozma, the ruler of Oz.    Read more interesting facts about Baumm’s Oz books and see artwork from all of them at Tres Sugar. Link   -via Holy Kaw!

Circular Beam of Electrons

Beam of electrons moving in a circle, due to the presence of a magnetic field. Purple light is emitted along the electron path, due to the electrons colliding with gas molecules in the bulb. (Photo: Marcin Bialek ) Oh, how I love you guys. In our recent post A Fiery Dance on the Sun , Neatoramanaut PlasmaGryphon kindly took the time to explain to us the physics behind solar flares. In the explanation , there was a link to Wikipedia article on Lorentz force , where I found this fascinating image of a circular beam of electrons in a Teltron tube . Neat, huh? ( Thanks PlasmaGryphon! )

Bees Can See the Electric Field of Flowers

Flowers are pretty and colorful to you and me, but to a bee, they’re downright electrifying. You see, bees can sense the electric field that surrounds a flower: Dominic Clarke and Heather Whitney from the University of Bristol have shown that bumblebees can sense the electric field that surrounds a flower. They can even learn to distinguish between fields produced by different floral shapes, or use them to work out whether a flower has been recently visited by other bees. Flowers aren’t just visual spectacles and smelly beacons. They’re also electric billboards. Learn how a flower’s electric field is actually also useful for bees as it tells them whether other bees have visited it before. Ed Yong of Not Exactly Rocket Science explains: Link

Clever Students Use Game Theory to Get Perfect Scores on an Exam

Dr. Peter Fröhlich of Johns Hopkins University grades exams so that the highest scoring exam receives a 100% grade and all others fall below on a curve. It wasn’t a Kobayashi Maru scenario , but his exams are hard. Fröhlich’s students devised a cunning plan to all get A grades. It involved boycotting the exam: Since he started teaching at Johns Hopkins University in 2005, Professor Peter Fröhlich has maintained a grading curve in which each class’s highest grade on the final counts as an A, with all other scores adjusted accordingly. So if a midterm is worth 40 points, and the highest actual score is 36 points, “that person gets 100 percent and everybody else gets a percentage relative to it,” said Fröhlich. This approach, Fröhlich said, is the “most predictable and consistent way” of comparing students’ work to their peers’, and it worked well. At least it did until the end of the fall term at Hopkins, that is. As the semester ended in December, students in Fröhlich’s “Intermediate Programming”, “Computer System Fundamentals,” and “Introduction to Programming for Scientists and Engineers” classes decided to test the limits of the policy, and collectively planned to boycott the final. Because they all did, a zero was the highest score in each of the three classes, which, by the rules of Fröhlich’s curve, meant every student received an A. Dr. Fröhlich abided by his grading policy and gave all students A grades, as well as congratulating them on their cooperative spirit: Fröhlich took a surprisingly philosophical view of his students’ machinations, crediting their collaborative spirit. “The students learned that by coming together, they can achieve something that individually they could never have done,” he said via e-mail. “At a school that is known (perhaps unjustly) for competitiveness I didn’t expect that reaching such an agreement was possible.

People of Timbuktu save Manuscripts from Invaders

The Ahmed Baba Institute of Higher Learning and Islamic Research in Timbuktu, Mali, holds a collection of 30,000 of the world’s most precious ancient manuscripts. Or it did until recently. On January 23rd, al-Qaida-linked extremists, who invaded Timbuktu almost a year ago, ransacked the library and set it on fire. The fire raged for eight days straight. What the extremists did not know was that only about 2,000 of the hand-written documents had been moved to the new library building. However, they didn’t bother searching the old building, where an elderly man named Abba Alhadi has spent 40 of his 72 years on earth taking care of rare manuscripts. The illiterate old man, who walks with a cane and looks like a character from the Bible, was the perfect foil for the Islamists. They wrongly assumed that the city’s European-educated elite would be the ones trying to save the manuscripts, he said. So last August, Alhadi began stuffing the thousands of books into empty rice and millet sacks. At night, he loaded the millet sacks onto the type of trolley used to cart boxes of vegetables to the market. He pushed them across town and piled them into a lorry and onto the backs of motorcycles, which drove them to the banks of the Niger River. From there, they floated down to the central Malian town of Mopti in a pinasse, a narrow, canoe-like boat. Then cars drove them from Mopti, the first government-controlled town, to Mali’s capital, Bamako, over 600 miles (1,000 kilometers) from here. “I have spent my life protecting these manuscripts. This has been my life’s work. And I had to come to terms with the fact that I could no longer protect them here,” said Alhadi. “It hurt me deeply to see them go, but I took strength knowing that they were being sent to a safe place.” It took two weeks in all to spirit out the bulk of the collection, around 28,000 texts housed in the old building covering the subjects of theology, astronomy, geography and more. The 2,000 documents that were in the new library were digitized, so the information survives even if the parchment does not. Link -via Metafilter (Image credit: AP/Harouna Traore)
