Refshaleøen. Den internationale Melodi Grand Prix-finale flytter ind i Eurovision Island i B&ampW Hallerne på Reftshaleøen. med plads til 10.000 kunstnere og deres følge, delegerede, pressefolk og fans. Refshaleøen er en del af Københavns gamle værfts- og industriområde, der er på vej til at blive forvandet til en moderne bydel med boliger og kreative uddannelser og erhverv.
Refshaleøen, Copenhagen harbour, Eurovision Island 2014 – Eurovision Song Contest.
Wikipedia: On 2 September 2013, Danmarks Radio (DR) announced that the Eurovision Song Contest 2014 will take place at B&ampW Hallerne, Refshaleøen. The surrounding location will be transformed into Eurovision Island, an Olympic Park style complex which will property amenities and the Press Centre for the entirety of the contest.[6]
Refshaleøen, originally an island in its personal proper but now annexed to the larger island of Amager, is a former industrial site in the harbor of Copenhagen, Denmark. For far more than a hundred years, it was home to the shipyard Burmeister &amp Wain which closed in 1996.
Refshaleøen is frequently employed as a venue for events and festivals.

A single Leading Fuel dragster 500 cubic inch Hemi engine tends to make far more horsepower than the very first 4 rows at the Daytona 500.

Beneath full throttle, a Leading Fuel dragster engine consumes 1½ gallons of nitromethane per second a fully loaded 747 consumes jet fuel at the identical price with 25% less energy getting made.

A stock Dodge 426 Hemi V8 engine can’t produce sufficient power to drive the dragster’s supercharger.

With 3000 CFM of air getting rammed in by the supercharger on overdrive, the fuel mixture is compressed into a near-solid type ahead of ignition. Cylinders run on the verge of hydraulic lock at full throttle.

At the stoichiometric 1.7:1 air/fuel mixture for nitromethane the flame front temperature measures 7050 degrees F.

Nitromethane burns yellow. The spectacular white flame seen above the stacks at evening is raw burning hydrogen, dissociated from atmospheric water vapor by the searing exhaust gases.

Dual magnetos provide 44 amps to every single spark plug. This is the output of an arc welder in every single cylinder.

Spark plug electrodes are entirely consumed in the course of a pass. Following 1/two way, the engine is dieseling from compression plus the glow of exhaust valves at 1400 degrees F. The engine can only be shut down by cutting the fuel flow.

If spark momentarily fails early in the run, unburned nitro builds up in the affected cylinders and then explodes with enough force to blow cylinder heads off the block in pieces or split the block in half.

In order to exceed 300 mph in four.5 seconds dragsters must accelerate at an typical of over 4G’s. In order to reach 200 mph well before half-track, the launch acceleration approaches 8G’s.

Dragsters reach more than 300 miles per hour ahead of you have completed reading this sentence.

Best Fuel Engines turn roughly 540 revolutions from light to light!

Like the burnout the engine must only survive 900 revolutions beneath load.

The red-line is in fact quite high at 9500 rpm.

The Bottom Line Assuming all the gear is paid off, the crew worked for free, and for as soon as Practically nothing BLOWS UP, each and every run expenses an estimated ,000.00 per second. The existing Best Fuel dragster elapsed time record is 4.441 seconds for the quarter mile (ten/05/03, Tony Schumacher). The prime speed record is 333.00 mph (533 km/h) as measured more than the last 66′ of the run (09/28/03 Doug Kalitta).

Putting all of this into perspective:

You are riding the average ,000 Honda Moto GP bike. Over a mile up the road, a Top Fuel dragster is staged and prepared to launch down a quarter mile strip as you pass. You have the advantage of a flying begin. You run the RC211V tough up by means of the gears and blast across the starting line and previous the dragster at an truthful 200 mph (293 ft/sec). The ‘tree’ goes green for both of you at that moment. The dragster launches and starts following you. You preserve your wrist cranked tough, but you hear an extremely brutal whine that sears your eardrums and within three seconds the dragster catches and passes you. He beats you to the finish line, a quarter mile away from exactly where you just passed him.

Think about it, from a standing start off, the dragster had spotted you 200 mph and not only caught, but practically blasted you off the road when he passed you inside a mere 1320 foot lengthy race course.

Shanghai Stampede 2014 ‘critical mass’ lesson: “DEMASSIFY – DO NOT JOIN THE MASSES – BACK TO HUMAN SCALE”

Shanghai Stampede 2014 ‘critical mass’ lesson: &quotDEMASSIFY – DO NOT JOIN THE MASSES – BACK TO HUMAN SCALE&quot

line 1) 临界质量 &quotCritical Mass&quot (science term/tipping point)

line two) 请勿加入群众 &quotDo not join the masses&quot (social/political term and a negation of Maoist ideology whereby there is always the incentive of the Communist Celebration (who claims to lead the masses) to ‘join the masses’.

&quotCrucial mass is the amount of fissile material necessary to sustain nuclear fission. Far more normally, ‘critical mass’ is similar to the tipping point notion&quot

De-Massify verb (used with object), demassified, demassifying.
1. to trigger (society or a social technique) to turn into much less uniform or centralized diversify or decentralize.
2. to break (some thing standardized or homogeneous) into elements that appeal to individual tastes or unique interests.&quot

… at a certain tipping point the SPECTACLE begins to CONSUME it is personal SPECTATORS, quantity alterations high quality, especailly of crowds, ‘critical mass’ was attainded at the Bund in Shanghai on New Year’s eve (1):

Commemorating the December 31 2014 SHANGHAI STAMPEDE at the Bund

Calling for a DE-MASSIFICATION of competing world cities with their spectacular festivities, all trying to have the greatest show on earth.

What we need is a renaissance of diversified human scale enjoyments at numerous locations, a revaluation of neighborhood and neighbourhood.

A government ‘of the people’ would launch directives and slogans like:




Exciting adequate the Hong Kong ‘South China Morning Pos’t (constantly properly informed on mainland China) runs right now (3/1/2015) an article with this heading:

&quotCensors suppress Shanghai stampede coverage as blame game starts&quot with a sub-line &quotLocal media sources say unprecedented difficult controls imposed on news of the tragedy&quot and the very first lines… &quotShanghai authorities have brought down a wall of strict censorship on neighborhood coverage of Wednesday night’s deadly stampede, as questions mount more than how such a tragedy could have occurred in the mainland’s wealthiest and very best-managed city. // Local sources said the censorship was &quotunprecedented and harsh&quot and officials were worried that they could be blamed for the stampede that killed at least 36 individuals. // A police supply mentioned several Huangpu district officials and police have been likely to lose their jobs more than the incident.&quot

Of course this tragedy is not simply because of a specific predicament in 1 of the largest Chinese cities, ‘stampedes’ happen all over the planet, in all kind of differing scenarios. (1) Nonetheless mass gatherings, festivities, tend to be one particular of the frequent causes. If a single desires to avert reoccurring than government and city authorities – from all over the planet – want to reassess mass-gatherings and festivities, start steering away from them, initiate gatherings on a more human scale, cease pushing huge numbers in every little thing all the time. Stampede examples adequate that could have been prevented, in the sphere of giant football stadiums and mass-prades, with one current infamous instance in Germany, about which I wrote this essay in the year 2010:

MASSE MENSCH GERMANY: FROM Adore PARADE TO Really like STAMPEDE or how really like was lost in a crowd July 24, 2010 by Tjebbe van Tijen.

(1) Crucial MASS I quote a web page from the South China Morning Post with this big size image (2250×3000 pixels)…. (this as direct access to the news paper’s web site for a certain web page might be limited):

&quotA mainland photojournalist at the scene of the New Year’s Eve stampede in Shanghai sensed one thing was wrong minutes just before the crush started. Recalling his narrow brush with death, Guo Xianzhong, 36, a Southern Metropolis News photographer going to from Guangzhou, stated the Bund seemed overcrowded as he waited to ring in the new year. Guo was capable to escape the crush and the photographs and video he took from the centre of the stampede captured the incident in vivid detail, going viral on the web. They supplied a blow-by-blow account of the stampede prior to official accounts were released. They also helped to set the record straight about some misunderstandings, including claims that the stampede was linked to a scramble for coupons to a nearby nightclub. &quotThe location was certainly overcrowded, there have been screams and cries. My instinct as a journalist told me something’s going to come about,&quot Guo said. He mentioned he climbed onto a rubbish bin, and from there managed to get on leading of a wall beside the staircase exactly where the stampede took location. That spot gave him not only safety from the crush but also a complete view of what occurred on the ground.&quot

Minox Contax Racetrack Playa

Image by ▓▓▒▒░░
Racetrack Playa in Death Valley National Park.

For most of the year Racetrack Playa in Death Valley, California is a dry lake, a completely flat expanse of cracked white clay. There are a few scattered stones on the surface, from a handful of centimetres in diameter to half a metre. Some of the stones have trails hundreds of metres long displaying that they have moved across the ground – but how?

Nobody has noticed 1 in motion, but geologists have tracked the stones progress for years, usually in March.

The most likely explanation entails the spring weather. Rain and melting snow from the surrounding hills leaves a lot of of the rocks partly-submerged in enormous, shallow pools. As temperatures fall at evening, ice can form a collar around the base of a rock. This creates enough buoyancy for strong winds to overcome friction with the lake bed. This is only possible simply because of the flatness of the Playa, which allows wind to gust at 90 mph close to the ground.

In any case, the movement probably on lasts less than a minute and might only happen every many years. This is probably why the sailing stones of Racetrack Playa have remained a single of the world’s more elusive climate phenomena.

The initial Space Shuttle orbiter, &quotEnterprise,&quot is a complete-scale test vehicle employed for flights in the atmosphere and tests on the ground it is not equipped for spaceflight. Though the airframe and flight control elements are like those of the Shuttles flown in space, this car has no propulsion system and only simulated thermal tiles due to the fact these functions were not necessary for atmospheric and ground tests. &quotEnterprise&quot was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long strategy-and-landing test flight system. Thereafter it was employed for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred &quotEnterprise&quot to the Smithsonian Institution’s National Air and Space Museum.

Quoting from Wikipedia | Space Shuttle Enterprise:

The Space Shuttle Enterprise (NASA Orbiter Vehicle Designation: OV-101) was the very first Space Shuttle orbiter. It was constructed for NASA as part of the Space Shuttle system to perform test flights in the atmosphere. It was constructed with out engines or a functional heat shield, and was for that reason not capable of spaceflight.

Initially, Enterprise had been intended to be refitted for orbital flight, which would have made it the second space shuttle to fly after Columbia. However, in the course of the building of Columbia, particulars of the final design changed, specifically with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the country. As this was an costly proposition, it was determined to be less expensive to construct Challenger about a body frame (STA-099) that had been created as a test article. Similarly, Enterprise was deemed for refit to replace Challenger soon after the latter was destroyed, but Endeavour was built from structural spares as an alternative.


Construction started on the first orbiter on June 4, 1974. Designated OV-101, it was initially planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A create-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named after the Starship Enterprise, featured on the tv show Star Trek. Even though Ford did not mention the campaign, the president—who for the duration of Planet War II had served on the aircraft carrier USS&nbspMonterey&nbsp(CVL-26) that served with USS&nbspEnterprise&nbsp(CV-6)—said that he was &quotpartial to the name&quot and overrode NASA officials.

The design of OV-101 was not the identical as that planned for OV-102, the 1st flight model the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A huge quantity of subsystems—ranging from major engines to radar equipment—were not installed on this car, but the capacity to add them in the future was retained. Alternatively of a thermal protection system, its surface was mainly fiberglass.

In mid-1976, the orbiter was utilized for ground vibration tests, permitting engineers to examine information from an actual flight car with theoretical models.

On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek have been on hand at the dedication ceremony.

Approach and landing tests (ALT)

Main write-up: Method and Landing Tests

On January 31, 1977, it was taken by road to Dryden Flight Research Center at Edwards Air Force Base, to begin operational testing.

Even though at NASA Dryden, Enterprise was used by NASA for a assortment of ground and flight tests intended to validate aspects of the shuttle plan. The initial nine-month testing period was referred to by the acronym ALT, for &quotApproach and Landing Test&quot. These tests included a maiden &quotflight&quot on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking qualities of the mated program. Ground tests of all orbiter subsystems have been carried out to confirm functionality prior to atmospheric flight.

The mated Enterprise/SCA mixture was then subjected to five test flights with Enterprise unmanned and unactivated. The objective of these test flights was to measure the flight traits of the mated combination. These tests had been followed with 3 test flights with Enterprise manned to test the shuttle flight control systems.

Enterprise underwent 5 totally free flights exactly where the craft separated from the SCA and was landed beneath astronaut handle. These tests verified the flight characteristics of the orbiter design and were carried out below several aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation problems had been revealed, which had to be addressed just before the 1st orbital launch occurred.

On August 12, 1977, the space shuttle Enterprise flew on its own for the 1st time.

Preparation for STS-1

Following the ALT system, Enterprise was ferried amongst several NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and solid rocket boosters (recognized as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.


With the completion of crucial testing, Enterprise was partially disassembled to allow specific elements to be reused in other shuttles, then underwent an international tour visiting France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (for the duration of the 1984 Louisiana Planet Exposition). It was also utilised to fit-verify the in no way-utilized shuttle launch pad at Vandenberg AFB, California. Finally, on November 18, 1985, Enterprise was ferried to Washington, D.C., where it became property of the Smithsonian Institution.


Soon after the Challenger disaster, NASA deemed using Enterprise as a replacement. Nevertheless refitting the shuttle with all of the required gear needed for it to be employed in space was considered, but as an alternative it was decided to use spares constructed at the same time as Discovery and Atlantis to develop Endeavour.


In 2003, following the breakup of Columbia in the course of re-entry, the Columbia Accident Investigation Board performed tests at Southwest Analysis Institute, which employed an air gun to shoot foam blocks of equivalent size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing leading edge. They removed a fiberglass panel from Enterprise’s wing to carry out analysis of the material and attached it to the test structure, then shot a foam block at it. Although the panel was not broken as a outcome of the test, the effect was sufficient to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was 2.five occasions weaker, this recommended that the RCC top edge would have been shattered. Extra tests on the fiberglass were canceled in order not to risk damaging the test apparatus, and a panel from Discovery was tested to determine the effects of the foam on a similarly-aged RCC top edge. On July 7, 2003, a foam effect test designed a hole 41&nbspcm by 42.five&nbspcm (16.1&nbspinches by 16.7&nbspinches) in the protective RCC panel. The tests clearly demonstrated that a foam effect of the type Columbia sustained could seriously breach the protective RCC panels on the wing leading edge.

The board determined that the probable lead to of the accident was that the foam effect brought on a breach of a reinforced carbon-carbon panel along the leading edge of Columbia’s left wing, allowing hot gases generated for the duration of re-entry to enter the wing and cause structural collapse. This caused Columbia to spin out of control, breaking up with the loss of the entire crew.

Museum exhibit

Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport before it was restored and moved to the newly built Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection after the Shuttle fleet is retired. When that happens, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the car in early 2010 and determined that it was secure to fly on the Shuttle Carrier Aircraft when once more.

Euromast is an observation tower in Rotterdam, constructed amongst 1958 and 1960. It was built for the 1960 Floriade, and is a listed monument because 2010. The tower is a concrete structure with an internal diameter of 9 m (30 ft) and a wall thickness of 30 cm (12 in). For stability it is constructed on a concrete block of 1,900,000 kg (four,200,000 lb) so that the center of gravity is beneath ground. It has a observation platform and a restaurant 96 m (315 ft) above-ground. Initially 101 m (331 ft) in height it was the tallest constructing in Rotterdam. It lost this position for a although, but regained it when the Space Tower was added to the leading of the developing in 1970, providing an additional 85 m (279 ft). Euromast is a member of the Planet Federation of Fantastic Towers.

Waiting for the “Night Witches”

Candid shot Zell am Ziller, Austria.

&quotNight Witches&quot is the English translation of Nachthexen, a Planet War II German nickname (Russian Ночные ведьмы, Nochnye Vedmy) for the female military aviators of the 588th Evening Bomber Regiment, known later as the 46th &quotTaman&quot Guards Night Bomber Aviation Regiment, of the Soviet Air Forces. The regiment was formed by Colonel Marina Raskova and led by Key Yevdokia Bershanskaya.

The regiment flew harassment bombing and precision bombing missions against the German military from 1942 till the end of the war. At its largest, it had 40 two-individual crews. It flew over 23,000 sorties and is stated to have dropped 3,000 tons of bombs. It was the most very decorated female unit in the Soviet Air Force, every single pilot getting flown over 800 missions by the finish of the war and twenty-three possessing been awarded the Hero of the Soviet Union title. Thirty of its members died in combat.

The regiment flew in wood-and-canvas Polikarpov Po-2 biplanes, a 1928 style intended for use as coaching aircraft and for crop-dusting, and to this day the most-produced biplane in aviation history. The planes could carry only six bombs at a time, so a number of missions per evening were essential. Though the aircraft were obsolete and slow, the pilots created daring use of their exceptional maneuverability they had the benefit of possessing a maximum speed that was lower than the stall speed of each the Messerschmitt Bf 109 and the Focke-Wulf Fw 190, and as a result, German pilots discovered them extremely hard to shoot down. An attack approach of the evening bombers was to idle the engine close to the target and glide to the bomb release point, with only wind noise left to reveal their location. German soldiers likened the sound to broomsticks and named the pilots &quotNight Witches.&quot Due to the weight of the bombs and the low altitude of flight, the pilots carried no parachutes

The funerary stele shows two figures standing 1 in front of the other. They are an athlete, the deceased young, and his attendant. The bust of the athlete is represented in 3-quarters, his head in profile. The features and the anatomy of the young are rendered with wonderful precision despite the relief is genuinely very low. The correct arm is lowered at the waist while the left arm is raised up to the shoulder and the palm turned towards the observer. The head of the young athlete is bent downward. His melancholy gaze is directed towards the attendant. The youth is standing in front of him, holding two standard tools form athletes: an aryballos containing ointment and a strigil.
