The art of fireworks‚ first originated in ancient China‚ with thefirst explosive being made from a mixture of black powder during theSung dynasty. It is believed that the explosive mixture was created bya combination of sulfur‚ saltpeter and charcoal. The Chinese foundthat the combination of these ingredients

question 1 on page 382-383 As I was reading Susan Griffin’s essay I found the structure confusing to some extent. She talks about one thing‚ compares it with her life and then jumps to another story. In her essay Griffin brings up many topics; cells‚ rockets‚ world war two. In a way‚ reading through Griffin’s essay and understanding it is like solving a puzzle. One piece of the puzzle gives you nothing about the whole picture. Once the pieces are assembled‚ the picture becomes clear. Griffin‚ throughout

thirteen‚ when he read The Rocket into Interplanetary Space by Hermann Oberth. The next year his mother gave him his first telescope and he soon decided to devote his life to rocketry and the exploration of space. In September 1929‚ seventeen-year old von Braun joined the Verein für Raumschiffahrt (VFR) assisting his mentor Oberth in tests of liquid-fuelled rocket engines. By the 1930 ’s‚ the German government became highly interested in the military development of rockets‚ and in pursuit of his dream

became the most important rocket designer of his time. During World War II‚ von Braun worked for the German army‚ developing missiles. This work resulted in the V-2 rocket‚ which used liquid fuel and could bomb targets in Europe. The structure of the V-2 rocket became the basis of the rockets used in space exploration programs in the US and the USSR after the war. After World War II‚ con Braun worked with the US army in the development of ballistic missiles. In 1960‚ his rocket development centre transferred

These were launched from the newly-established ThumbaEquatorial Rocket Launching Station (TERLS) ‚ built near Thiruvananthapuram in southern Kerala. Initially‚ American sounding rockets like the Nike-Apache‚ and French sounding rockets like the Centaure‚ were fired and used for studying the upper atmospheric electrojet‚ which until then had only been studied from ship-based sounding rocket launches in the

The Chinese were also involved in pyrotechnics‚ developing rockets by 10th century and using fireworks in 1200 AD. Chinese firecrackers became a popular item in the United States when trade begun in the 1800’s‚ and still remain popular in the United States today‚ accounting for well over half of the annual sales

forward thrust when air is pushed in the direction opposite to flight. This can be done in several ways including by the spinning blades of a propeller‚ or a rotating fan pushing air out from the back of a jet engine‚ or by ejecting hot gases from a rocket engine. The forward thrust is proportional to the mass of the airstream multiplied by the difference in velocity of the airstream. Reverse thrust can be generated to aid braking after landing by reversing the pitch of variable pitch propeller blades
