Modern rockets

In 1903, the mathematics teacher Konstantin Tsiolkovsky secondary education (1857-1935) published ( “The exploration of outer space by methods of reaction”), the first serious scientific work that was spaceflight. The Tsiolkovsky rocket equation-the principle that governs rocket propulsion-is named in his honor. His work was particularly unknown outside the Soviet Union, where he inspired extensive research, experimentation, and training Cosmonautics Society. His work was republished in 1920 in response to Russian interest in the work of Robert Goddard.Among other ideas, Tsiolkovsky accurately proposed the use of liquid oxygen and hydrogen as an excellent engine torque, determined the structure should be built and designed the way it should be the rockets to increase the efficiency of mass and thus increase range. The first rockets were very inefficient due to the amount of energy and heat that was discarded in the exhaust. Modern rockets were born later, after receiving a grant from the Smithsonian Institution, Robert Goddard joined by a supersonic nozzle (Laval nozzle) to the combustion chamber of the rocket motor. That turned the hot gas nozzle of the combustion chamber at a hypersonic gas propellant (jet), more than doubling the thrust and greatly increasing efficiency. In 1923 Hermann Oberth (1894-1989) published Die Rakete zu den Planetenr umen ( “The Rocket into Planetary Space”), a version of his dissertation, after the University of Munich rejected it.This book is cred with being the first serious scientific work on the subject that has received international attention. During the 1920s a large number of organizations researching on the rockets appeared in the United States, Austria, England, Czechoslovakia, France, Italy, Germany and Russia. In the mid-20s, German scientists had begun experimenting with rockets which used liquid propellants capable of a great distance and high altitude. A team of amateur rocket engineers had formed the Verein f r Raumschiffahrt (German Rocket Society, or VFR) in 1927, and in 1931 launched a liquid-propellant rocket (using oxygen and gasoline). From 1931 to 1937 the most extensive scientific work on rocket engine design occurred in Leningrad (now St. Petersburg) in the gas dynamic laboratory. Subsidized goods and a good number of staff, was created more than 100 experimental engines under the direction of Valentin Glushko.The work involved regeneration cooling, hypergolic ignition and fuel injector designs that included internal mixers mixers and injectors supplying secondary propellants. The work was curtailed by Glushko’s arrest during Stalinist purges of 1938. A similar but less extensive work being undertaken by the Austrian professor Eugen S nger. In 1932, the Reichswehr (which in 1935 became the Wehrmacht) began to show interest in rockets. Military restrictions imposed by the Treaty of Versailles limited Germany’s access to long-range weapons. Seeing the possibility of using rockets and artillery, the Wehrmacht initially subsidized the team VfR but since they were only focused on the scientific side, he created his own research team, with Hermann Oberth as a senior member.At the behest of military leaders, Wernher von Braun, at the time a young aspiring rocket scientist in the field, joined the military (followed by two ex-members of the team VfR) and developed long-range weapons for use in World War II by Nazi Germany, notably the A-series rockets, which led to the V-2 rocket (initially called A4). In 1943 began production of V-2 rockets. The V-2 represented a greater step forward in the history of rockets. The V-2 had a range of 300 km and carried a warhead of 1,000 kg amatol. The rocket differs only in painstaking detail of modern rockets, bombs had turbines, inertial guidance and other capabilities. Thousands of them were launched against the allied nations, notably England and France and Belgium. Since there could be intercepted, the design of its guidance system and its conventional warhead of the V-2 made a weapon insufficiently accurate against military targets.In Britain 2,754 people died and 6523 were injured before the season was over pitches. Although the V-2 did not significantly affect the course of the war, provided a demonstration of the potential lethality of guided weapons. At the end of the Second World War, the Russian military and scientific equipment, the British and the Americans raced to capture technology and personnel of the German rocket program at Peenem nde.


Cycling as a sport was born in 1890 but the bike has a much more ancient origin in China, India and Egypt. However, it is considered that derives directly from celer fero, which was a bar with two wooden wheels and is propelled by the feet of the rider.

Carnival: Doctors Warn Of Excessive Alcohol Consumption

Million people suffer from, or after the “great days” under the problems that alcohol mis () are due to consumption. Excessive alcohol consumption leads in principle to the classic hangover symptoms such as nausea, vomiting, “Nachdurst, headaches, and more or less discomfort and stressful, however there is no remedy for the prevention or treatment, emphasizes quality Medic’s spokesman, Trevor Byrne today in Cologne. The physicians of the medical Beratungsportals have effective tips together, so after the celebrations at Carnival or Fasching only a tiny kitten and adult cat is not a threat: Quali Medic-internist Dr. Claudia Bernholt advises to Do not drink alcoholic beverages on an empty stomach. When the stomach through food and non-alcoholic beverages is filled delay, the absorption of alcohol and this does not rise as quickly to his head, says Claudia Bernholt. Ideal preparation for this are meatballs rollsthe traditional pickled herring or herring herrings. Anyone who enjoys this as a cat killer known seafood prior to alcohol consumption and not at the “Katertag”, prepares his body better for the neurotoxin alcohol. Alcohol, but also acts a diuretic – it also drives fluid from the body and thus the organism loses plenty of water-soluble substances such as minerals. The water and electrolyte loss is responsible for many unpleasant effects of alcohol consumption. Therefore, the salt-rich fish should be before the consumption of alcohol on the menu are available and not after. Dr Claudia Bernholt recommends the consumption of alcohol or an extra dose of vitamin C, because the water-soluble vitamin to help prevent such a hangover in the mineral magnesium. To reduce alcohol consumption as a whole, it is advisable that follows each glass of beer, wine, champagne or liquor a large glass of mineral water. That balances out the alcohol fluid and electrolyte loss. Whether the intervention was successful, can be easily seen from the fact that thenext day with “Nachdurst” begins. Nachdurst is a sign of an extreme loss of water via the urine. In addition, Dr. Claudia Bernholt advises to not “cheap booze” and alcoholic “drink of unknown origin” to. But are also branded spirits contain many different substances present, which can lead to complaints, says internist Bernholt. Particularly katerfrdernd especially cognac, schnapps, brandy, red wine and rum What matters is the absolute amount of alcohol, and folk wisdom “beer to wine, which are let ‘be!” In the realm of fairy tales food banished. If you have a glass of beer, a glass of wine, get them alone certainly no hangover. On the following day, it is important for fresh air, provide mineral-rich drinks such as fruit juice and light food. Optimal is fruit yogurt or bread and jam, recommends Quali Medic-Spokesperson and nutrition expert Trevor Byrne concluded. For more information and free medical consultation .

When Children Go Ballistic

Children, unlike adults in our modern society the right to effusive activity, impulsivity and unconcentrated behavior. In many children are at extreme variants of the above behaviors by only the standard deviation, which disappear in the coming weeks and months, usually. In 2-6% of our children and teenagers is however still a ADHD. ADHD stands for attention deficit hyperactivity disorder and presents as the most common psychiatric illness of the child – and adolescence. Inspired by Heinrich Hoffmann Struwwelpeter ADHD is also known as Zappelphillipp syndrome. In many print media are computer games, made excessive television or lack of diligence causally responsible for the disease. Scientific studies have clearly demonstrated that a complex dysfunction of the neurotransmitter metabolism is responsible for ADHD. Hyperactivity, impulsivity and inattention are the classic symptoms ofAttention deficit hyperactivity syndrome. The severity of individual symptoms can be here but are quite different. In some patients, we will therefore speak of a fidget, while others are more Traumsuse the term is correct. Before it can be called ADHD, should be available in the core symptoms of hyperactivity, impulsivity and poor concentration for at least six months, and the different spheres of life of the child (school, family, leisure). The diagnosis should always be made by an experienced child and adolescent psychiatrist. Untreated ADHD has discovered or not may-reaching consequences for the patient, as truancy, expulsion from school, addiction, anxiety, depression or suicidal behavior are often closely associated with ADHD. The diagnosis was made only once, it is important to initiate treatment promptly to prevent possible late effects. In addition to drug therapy with Ritalin, Concerta and Strattera are also behavioral, parental andTeacher training and psychotherapy for the treatment of disease used. Studies have shown that the combined use of different forms of therapy leads to the greatest possible success. Finally, it is again important to note that we are dealing with ADHD is not exclusively a problem of individual patients, but also our schools, the social environment and, ultimately, our entire society with the consequences and repercussions are fighting the disease. The author of this article, Dr. med Jrgen Mayer informs on its website on general health issues and provides guidance with respect to a healthier lifestyle.

Parabolic Flights – Holidays By Weightlessness

The US-American Anousheh Ansari in 2006 as first space tourist paid around 16 million euros for their spacecraft to the Space Station. Those who lack the wherewithal for such an excursion, which can occur even for a few thousand dollars to several minutes of weightlessness – a parabolic flight. Typically, parabolic flights are made to conduct scientific experiments or testing devices that will work in space. Even special effects in movies are sometimes produced on parabolic flights, for example, various scenes from the movie “Apollo 13” starring Tom Hanks. On parabolic flights converted military transport planes and civil airliners like the Airbus to rise at a 45 degree angle sharply upward to a height of up to 8500 meters. Just before the top of the engines are throttled, the plane is still rising a little to the vertex of the parabola and then also falls in a 45 angle to the ground again until it is intercepted by the pilots. During the steep climb and the interception of the machine almost Prevailsdual gravity in an airplane. At the top of the parabola is after switching off the engine reaches the actual weightlessness, which lasts approximately 25 seconds. Usually a sequence of parabolas are flown so that the whole time is just under 10 minutes of weightlessness. Not everyone tolerates the conflicting information that disclose the balance organ in the inner ear and the eye to the brain. About 13 percent of all passengers who participate for the first time a parabolic flight, are plagued by violent vomiting. As is often the drugs did not help to be proactively distributed to all. Hence the nickname “Kotzbomber” for the parabolic flight aircraft. But the team is prepared for such cases and has a lot of bags in stock for those who have their stomach contents again have to give away. Because with a bag is not enough, as a rule, if it has seen someone catch. Nevertheless Schwerkraftmde to find enough people who want to experiment, so that there is already a commercial airline that offers parabolic flights.For around $ 4000 you can take off from Fort Lauderdale, Miami, out. Flight and accommodation are of course still do so. That we may be in a padded experiencing empty evacuated the aircraft fuselage, together with over 20 like-minded people a sense that otherwise it is only in outer space. The physical demands of parabolic flight passengers are fortunately much less than that of astronauts. It should be easy in normal health, with a blood pressure no higher than 160/100. Then stay for a weekend of weightlessness is nothing in the way except for a few thousand euros or dollars. Those who also still has a robust stomach is clearly superior and can enjoy the trip much better than those which are parabolas in the course of so poor that they only want to die.

Soccer On TV, Pay TV

Pay TV also takes in Germany, an increasingly important role since then to more than one provider are seriously committed to the German market, however, found the winner here, as everywhere, the competition also boosts the business. How then can I personally benefit from this competition Arena is offered only for a short time, however, has the Exclusive rights to the 1st and 2 Bundesliga secured. Here are some games live and in full with everything your heart desires. The focus of Arena is the fun of the game and it is trying to do everything better than Premiere, which have kaputtgeredet from the perspective of managing director Dejan Jocic many games. Premiere, however, has not disappeared entirely from the market, they have the right at the pinnacle of football, the Champions League. This jewel is Presented in the usual quality of Premiere, good presenters, and a competent reporting. Crucial to the premiere of confidence in is the new IPTV, IPTV has been in collaboration with Telekom for live broadcasts of the 1st and 2Bundesliga created over the Internet, here was a new step and it remains to be seen whether it is accepted by the fans. Who is mainly via the Internett Informs should become familiar with the offer of Premiere. Arena is Inveterate fans a must. However, those who have always been with the information from the free TV was satisfied should continue to rely on the private and public television stations. Here are the ARD, ZDF and DSF, the most popular channels, they report on Saturday evening but not before 18:30.
