Santhosh Hari Krishnan Professor M Gaboury Law 1038 27 November 2016 SPACE SHUTTLE CHALLENGER ACCIDENT INVESTIGATION Introduction: The space shuttle challenger took away the life of 7 crew members on January 28‚ 1986. The spacecraft was broke up into small parts on the Atlantic Ocean and the banks of central Florida on US time 11:39 am. The reason behind the disintegration was the O-Ring seal in the right solid rocket booster failed at the liftoff of the shuttle.The failure caused a breach in

amplification of radiation) was initially used‚ but later replaced with “laser”. Laser technology is at the core of the wider area of photonics‚ essentially because laser light has a number of very special properties: * It is usually emitted as a laser beam which can propagate over long lengths without much divergence and can be focused to very small spots. * It can have a very narrow bandwidth‚ whereas e.g. most lamps emit light with a very broad spectrum. * It may be emitted continuously‚ or

Alexander Graham Bell and his assistant Charles Sumner Tainter created the Photophone‚ at Bell ’s newly established Volta Laboratory in Washington‚ DC. Bell considered it his most important invention. The device allowed for the transmission of sound on a beam of light. On June 3‚ 1880‚ Bell conducted the world ’s first wireless telephone transmission between two buildings‚ some 213 meters apart Its first practical use came in military communication systems

stored on a sugar cube sized plastic. This isn’t too far from reality. It works by splitting a blue laser beam in two‚ a reference beam‚ and a data beam‚ which contains the information converted to binary code. Then the data beam is modulated by the SLM (Spatial light modulator – like in the digital projectors)‚ that creates a very high density array of 1‚5 million pixels. Where the two beams intersect‚ a holographic interference pattern is formed. When focused on an unexposed‚ light sensitive holographic

Place the object on the pan of the triple beam balance scale. 3. Move the riders (starting with the 100g and ending with the 1g)(move one at a time-make sure) until the balance pointer rests at zero. 4. Add the measurements on all the riders and record the quantity in g. Finding Mass By Difference 1. Zero out the triple beam balance. 2. Find the mass of the empty
