Lighter than air

Casey was an ordinary person like everyone else in The world; all had the same dull grey eyes, the black short hair and they all had the same basic face. Everyone was the same, nobody was different. Any individual under the age of 18 went to a learning facility; each boring classroom holding 25 methodically placed desks, where each unresponsive child would sit. The teachers were all the same, they said the same repeating words that have stuck in our brains like sap on a tree. Casey sat there, that

into a brilliant blaze, oxygen fueling the size as gasoline continues to burn. Standing in the shadows, with nothing more than a psychotic grin giving away his location, his dark eyes watched as the flames began to consume everything in its path. Low laughter rumbled in his chest before it spilled out into the night, twisting into the crackling sound as sparks flew into the air. It was as if the sparks danced with the smoke that billowed higher and higher. It was a mesmerizing sight, leaving a feeling

astronomy, and mathematics. However, he is most known for proving Copernicus’s claim that Earth is not flat. Copernicus also said that we rotated around the sun, not the other way around. Galileo proved this theory by inventing a better telescope than the Dutch telescope. His improved telescope helped him see the rings of Saturn, the Galilean moons of Jupiter, the phases of Venus, and even sunspots. There are some doubt when people say that he was the person who invented the telescope. However,

1. The Regular Soda may have sunk since the sucrose sugar weighs more than the aspartame sugar that is in the Diet soda. One more possibility is that the Diet soda had more carbonation injected into it than the Regular soda, making the Regular soda sink lower and Diet soda float. 2. Another possibility is that the Diet soda had a malfunction while in the factory process and it never got filled with soda and only air. Although it is rare that a mistake like that would happen, but malfunctions occur

The velocity profile at the vents is simply shown in Fig. 1. At the top of the vents, because the smoke in the fire floor is lighter than the air in the atrium and outside, pressure difference between the fire floor and outside (atrium as the same) is larger than at the lower place of the vents. At the bottom of the vents, the pressure difference gets negative to that at the top. So there should be a zero-pressure-difference or zero-velocity

History of the Fire Service When you hear the words “Fire Department” what do you think of? For most people the first thing that comes to mind is a big red truck with flashing lights and loud sirens and horns. Or people in bunker gear, helmets and air packs carrying axes and hoses. But it was not always that way. In the beginning it was nowhere near how it is today. Fire Fighting is defined as “the action or process of extinguishing fires”. The first fire department was created in 24 B.C. by Roman

frustrating to a car owner than a flat tire, especially when that flat tire is discovered just before a big getaway. Remedying a deflated tire can be a chore, but when you introduce an air compressor to the situation it becomes a whole lot easier. What Is An Air Compressor? - An air compressor is a device which is used to compress and store air. When the time comes to release the air into another object, the gas is pushed into its new home with immense force, which is what makes air compressors so useful

In 1958, as the United States Government sought to reorganize its defense establishment, President Dwight D. Eisenhower argued that “separate ground, sea and air warfare is gone forever. If ever again we should be involved in war, we will fight in all elements, with all services, as one single concentrated effort.” Eisenhower based his assessment on his experiences as Supreme Allied Commander in Europe during World War II, but his insight has had a tremendous influence on the way that the armed

As the airfoil approaches the stalling speed, the point of transition, or separation point, moves forward enough to exceed the design factor of the wing. An airfoil is any surface used to help lift and control the airplane, by creating or moving the air currents. The stalling angle is

V.Q. was standing in the bed of the Black Beast. The truck’s nose pointed in the bus garage’s direction like a sentinel keeping watch. He had his rifle rested on the pickup’s roof and was letting loose rounds faster than a Marine sniper. “Lovienthal, get in!” Mary snapped at him and he did as he’d been told, still cheering at the realization that his friend was alive. The pain of his twisted ankle temporarily vanishing as adrenaline coursed through him. Chuckles ran up to Lovienthal
