the Laissez Faire ideal of liberalism. There were different forms of socialism as it evolved over the years. Throughout the 19th century‚ Europe saw an uprising and evolution of socialism led by key names Karl Marx‚ Henri de Saint-Simon‚ Charles Fourier‚ and Robert Owen. It created equality for the majority of workers and prompted ideas of revolution. Socialism was partly rooted in the French Revolution‚ with a number of radical Jacobins taking the idea of political equality for all and moving it

Introduction CL-20 is a energetic compound with high density‚ good oxygen balance (-11%) and high explosive power. However‚ CL-20 has failed to see widespread implementation due to high mechanical sensitivity‚ it is relatively easily detonated by physical forces in comparison to other secondary explosives. While cocrystal CL-20/TNT exhibited a mechanical impact sensitivity greatly reduced relative to that of pure CL-20‚ it was also expected to feature reduced explosive power due to the

ECET345 Signals and Systems Homework #4 Name of Student ______________________________ 1. A shiny metal disk with a dark spot on it‚ as shown in figure below‚ is rotating clockwise at 100 revolutions/second in a dark room. A human observer uses a strobe that flashes 99 times/second to observe the spot on the metal disk (a strobe is a flashing light whose rate of flashing can be varied). The spot appears to the human observer as if it is rotating slowly. Hint: This is equivalent
