In the early 1800s, the world witnessed the beginning of the industrial revolution through which the agrarian society shifted to industrialization and urbanization [1]. Coal, water, and steam were predominantly used to drive large steam engines that were used in the textile and manufacturing industr...
the electrons move through graphene a bit like photons (wave-like particles of light), at speeds close enough to the speed of light (about 1 million meters per second, in fact) that they behave according to both the theories of relativity and quantum mechanics, where simple certainties are ...
Sam's Laser FAQ is NOT an academic paper or reference work on quantum mechanics, gas discharges, or solid state physics. You can relax. It is about getting your hands into lasers safely and on a realistic budget. There is only a bare minimum of heavy math and only a few equations. The...
Condensed matter physics is a remarkable domain where the effects of quantum mechanics combine with the presence of a very large (∼ 10 23 ) coupled degrees of freedom. The interplay between these two ingredients leads to the richness of phenomena that we observe in every- ...
for example, that makes the world comprehensible and gives us faith in its ultimate simplicity.For example, at the atomic level weird quantum mechanics rules,but larger systems are well described according to Newtonian laws,while engineers often use empirical rules, and so do the social scientists...
A condensed (142-page) overview that takes us from early ideas of Earth's magnetism to quantum theory, relativity, and more. The Man Who Changed Everything by Basil Mahon, John Wiley, 2003. A readable and easy-to-understand introduction to James Clerk Maxwell's life and work. Electricity ...
