Even though airplanes were a relatively new invention, the race for air superiority started during World War I.
Lt. Col. Stewart Francis Alexander, asleep in his quarters at Allied Force Headquarters in Algiers, was awake at the first harsh jangle of the telephone. There appeared to be a developing medical crisis in Bari. Too many men were dying, too quickly, of unexplained causes. The symptoms were ...
Airplanes Helicopters Blimps Sailboats Motor boats Submarines Robots Animals While the mechanics of how they operate can differ greatly between different toys, the basic principle is the same. All radio controlled toys have four main parts: Transmitter - You hold the transmitter in your hands to con...
World War I raged across Europe’s western and eastern fronts after growing tensions and then the assassination of Archduke Franz Ferdinand of Austria ignited the war. Trench warfare and the early use of tanks, submarines and airplanes meant the war’s battles were devastatingly bloody, claiming ...
Airplanes are still allowed to use leaded gasoline, and octane ratings of 115 are commonly used in super-high-performance piston airplane engines (jet engines burn kerosene, by the way). Another common additive is MTBE. MTBE is the acronym for methyl tertiary butyl ether, a fairly simple ...
They were the cowboys of the air. They were the first postmen to deliver air mail. The most important base across the West was Cheyenne, Wyoming. These brave pilots flew in old WWI biplanes, open to the elements, year-round. Their mission was to push America into the next phase of tec...

classifier (Lynch2018). Since the bulk mining technology is mainly used in copper mining, but not in zinc mining, which predominantly takes place underground, the decisive technological improvements that lowered the price plateau were probably beneficiation methods like flotation or the Dorr rake ...
do some things right. Upon entering my PhD this year, though, I’ve decided to cast my fears of failing aside. This does not mean that I’m going to jump out of airplanes or perform in The Nutcracker, it simply means that I’m going to try to push myself a little bit further int...
