Friedwardt Winterberg (born June 12, 1929) is a German-American theoretical physicist and was a research professor at the University of Nevada, Reno.He is known for his research in areas spanning general relativity, Planck scale physics, nuclear fusion, and plasmas.
Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...
Under Massey, the Physics Department moved away from researching the physics of metals and liquids, and focused on particle physics and upper atmosphere physics. [20] Massey saw the potential of computers. He arranged with Andrew Booth for a copy of his All Purpose Electronic Computer, and recruited two programmers, Joan Lawson and Jane Wallace ...
The oldest evidence of stone-tipped projectiles, which may or may not have been propelled by a bow (c.f. atlatl), dating to c. 280,000 years ago, were found in Ethiopia, present day East Africa. [1] The oldest evidence of the use of bows to shoot arrows dates to about 10,000 years ago; it is based on pinewood arrows found in the Ahrensburg ...
t 1 and t 2 are times when the impulse begins and ends, respectively, m is the mass of the object, v 2 is the final velocity of the object at the end of the time interval, and; v 1 is the initial velocity of the object when the time interval begins. Impulse has the same units and dimensions (MLT −1) as momentum.
A 1 km long mass driver made of superconducting coils can accelerate a 20 kg vehicle to 10.5 km/s at a conversion efficiency of 80%, and average acceleration of 5,600 g. [ 10 ] Earth-based mass drivers for propelling vehicles to orbit, such as the StarTram concept, would require considerable capital investment. [ 11 ]
[1] [2] The CCEMG launcher had an overall mass of only 273 kg despite its solid armature and its structurally stiff makeup, which resulted from incorporating a directional preloading mechanism, ceramic sidewalls, and a composite overwrap in its design. The performance of the CCEMG launcher relied on the system's directional preloading mechanism ...
