ABSTRACT:- Electromagnetic Pulse generation technology has matured to the point where Electro -magnetic bombs are becoming technically feasible, with uses warfare. The development of these weapons allows there use in a non nuclear way.
Abstract By introducing virtual 4th dimension to represent time in similar manner like 3 dimensions of space which can be measure in terms of length, the attempt is made to explain how velocity of the object in “Special Theory of Relativity” causes time dilation and how matter affects time in case of “General Theory of Relativity”. Same concept has been used to solve the “Galaxy Rotation Curve” problem and pioneer anomaly without need of any dark matter. Finally, it is shown that, increase in time affects gravity giving new definition to gravity based on which explosion of black hole and evolution of Universe is predicted.
The purpose of this lab report was to show that friction is involved in sport and can influence decisions on designing and buying footwear. The two experiments based around this report were on the coefficient of Friction and the angle of Friction. Both experiments were carried out in a laboratory at the University of Sunderland. Students from the University undertook the experiments and discovered that the best type of footwear to use for frictional purposes are trainers with thick tread wear on the sole of the shoe. The most frictional type of shoe used was the Adidas Barricade having a coefficient of friction of 0.78. In the second experiment metal was determined to have the highest coefficient of friction out of the surfaces the report used. It showed that metal had a coefficient of friction of 0.84, with the lowest being rubber reporting a score of 0.6.
Abstract This zero energy theory has great advantage over all other theories by its inner consistency due to which it can be used at microscopic as well as macroscopic level also. By using this theory, the attempt has been made in order to solve physics some mysterious unsolved problems like, dark matter, definition of space, expansion of the Universe and Gamma ray burst, origin of gravity, loss of mass and jets of black hole, curvature of space-time, equivalence between inertia and gravitational mass, difference in mass of proton and electron even having same value of charge, meaning of antimatter, the Universe with no anti matter etc. Thus, this theory can be used for unification of fundamental forces without need of any string i.e. no need of 11 dimensions, parallel universes, virtual particles like graviton etc.
Albert Einstein was born at Ulm, in Wurttemberg, Germany, on March 14, 1879. Six weeks later he and his family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium. Later, they moved to Italy and Albert continued his education at Aarau, Switzerland. In 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, the year he earned his diploma and received a Swiss citizenship and he accepted a position as technical assistant in the Swiss Patent Office. In 1905 he went for his doctor's degree. In 1914 he was appointed Director of the Kaiser Wilhelm Physical Institute and Professor in the University of Berlin. He became a German citizen in 1914 and remained in Berlin until 1933. He became a United States citizen in 1940. During the 1920's he lectured in Europe, America and the Far East and he was awarded Memberships to all the leading scientific academies throughout the world. He gained numerous awards for all of his work, including the Copley Medal of the Royal Society of London in 1925, and the Franklin Medal of the Franklin Institute in 1935. He married Mileva Maric in 1903 and they had a daughter and two sons. He died on April 18, 1955 at Princeton, New Jersey.
At the end of the first chapter, Hawking ends with a thought provoking statement; “Someday these answers may seem as obvious to us as the Earth orbiting the sun – or perhaps as ridiculous as a tower of
