Merkers Adventure Mines
Merkers Adventure Mines are a visitor attraction in Krayenberggemeinde in the Wartburgkreis district of Thuringia, Germany, owned and operated by K+S AG of Kassel. They lie near the village of Merkers. The mines have a long history of salt extraction, and hold the record for concealing large amounts of Nazi gold during World War II. A hundred tons of gold and many works of art presumed to be stolen were discovered by the liberating United States Army in 1945. Context The Merkers Mine drops 860m below the surface into the ' Werra-Revier' band of potash bearing salt. There, at a constant temperature of 28C, are 4600 kilometers of tunnels. Visitors are lowered in the hoisting cage at over 10m/ sec (30 km/h) down to the 500m galleries. There they are driven on 20-kilometre long tour of the mine, seeing an underground mining museum, a room where in 1945 the 'Gold und Devisenreserven der Deutschen Reichbank' dubbed the Nazi gold was stored, the world's largest underground bucket- ...

Len Deighton
Leonard Cyril Deighton (; born 18 February 1929) is a British author. His publications have included cookery books, history and military history, but he is best known for his spy novels. After completing his national service in the Royal Air Force, Deighton attended art school in London, and graduated from the Royal College of Art in 1955. He had several jobs before becoming a book and magazine illustrator—including designing the cover for first UK edition of Jack Kerouac's 1957 work ''On the Road''. He also worked for a period in an advertising agency. During an extended holiday in France he wrote his first novel, ''The IPCRESS File'', which was published in 1962, and was a critical and commercial success. He wrote several spy novels featuring the same central character, a working-class intelligence officer, cynical and tough. Between 1962 and 1966 Deighton was the food correspondent for ''The Observer'' and drew cookstrips—black and white graphic recipes with a limited nu ...

Episodes Treasure hunt The treasure hunt is a series of online mathematical challenges. The BBC planned to offer the challenges to 1000 participants selected from among people who applied to participate via Twitter or email. There are three stages to the treasure hunt: The Codebreakers, the Ultimate Challenge, and the Finale. Stage 1: The Codebreakers The first puzzles are "The Codebreakers". These consist of three wheels, one relating to each episode. Each Codebreaker has six different questions and chal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salt Crystal
Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of Salt (chemistry), salts; salt in the form of a natural crystallinity, crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater. The open ocean has about of solids per liter of sea water, a salinity of 3.5%. Sodium in biology, Salt is essential for life in general, and saltiness is one of the Basic tastes, basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food, including otherwise unpalatable food. Salting (food), Salting, brining, and pickling are also ancient and important methods of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring (hydrology), spring water to extract salts; a Salt in Chinese History#Ancient China ...

Crystal Grotto
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laser Show
A laser lighting display or laser light show involves the use of laser light to entertain an audience. A laser light show may consist only of projected laser beams set to music, or may accompany another form of entertainment, typically musical performances. Laser light is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection. This inherently more focused beam is also extremely visible, and is often used as an effect. Sometimes the beams are "bounced" to different positions with mirrors to create laser sculptures. Function Scanning Laser scanners reflect the laser beam on small mirrors which are mounted on galvanometers to which a control voltage is applied. The beam is deflected a certain amoun ...

Bucket-wheel Excavator
A bucket-wheel excavator (BWE) is a large heavy equipment machine used in surface mining. The primary function of BWEs is to act as a continuous digging machine in large-scale open-pit mining operations, removing thousands of tons of overburden a day. What sets BWEs apart from other large-scale mining equipment, such as bucket chain excavators, is their use of a large wheel consisting of a continuous pattern of buckets used to scoop material as the wheel turns. They rank among the largest vehicles (land or sea) ever produced, and the largest of the bucket-wheel excavators (the 14,200 ton Bagger 293 still holds the Guinness World Record for the heaviest land-based vehicle ever constructed). History Bucket-wheel excavators have been used in mining for the past century, with some of the first being manufacture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
