Central Academy of Technology and Arts (CATA) is a public high school located in Monroe, North Carolina, and also Union County's first magnet high school. [2] Unlike regular public high schools, students at Central Academy have the opportunity to have a major course of study in an academy of their choice that will give them a head start towards their future careers in life.
[1] He complained that gearing was a field dominated by empiricism in which science had so far played little role, so that it had hardly progressed in 150 years, but Brian Hayes found sophisticated mathematical concepts in use in the field and, for him, a surprising degree of interchange between mathematics and mechanics. By 2000, many of the ...

Engineering has existed since ancient times, when humans devised inventions such as the wedge, lever, wheel and pulley, etc. The term engineering is derived from the word engineer, which itself dates back to the 14th century when an engine'er (literally, one who builds or operates a siege engine) referred to "a constructor of military engines".

Model 525 serial numbers 0001 to 0359, powered by Williams FJ44-1A turbofans, are marketed as the CitationJet. With Tamarack winglets, it burns 600 lb (270 kg) of fuel per hour at 342 kn (633 km/h) and flight level (FL)410, rising to 700 lb (320 kg) per hour without winglets at FL380 and 1,020 lb (460 kg) at FL290.
Bell Aerosystems began development of a rocket pack which it called the "Bell Rocket Belt" or "man-rocket" for the US Army in the mid 1950s. [1] It was demonstrated in 1961 but 5 gallons of hydrogen peroxide fuel needed for 21 seconds of flight time did not impress the army.
