3 days ago · Instead, one must start to take into account Einstein's theory of special relativity, which deals with the "special" case of physics in the absence of gravity. The more "general" case of general relativity takes into account gravitational effects.
5 days ago · Special relativity is beyond weird. Among its many statements are that moving clocks run slow and that moving rulers shrink. But how are we supposed to make sense of this? To understand the...
2 days ago · Albert Einstein (born March 14, 1879, Ulm, Württemberg, Germany—died April 18, 1955, Princeton, New Jersey, U.S.) was a German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect.
1 day ago · This is just one of the discoveries revealed by Albert Einstein’s Special Theory of Relativity, which revolutionized physics. Perhaps the most famous equation in science, E = mc2, revealed that matter and energy are equivalent, setting the stage for atomic bombs and nuclear power plants.
5 days ago · What’s “special” about the special theory of relativity? Why did the theory initially seem to be dead on arrival? What does it mean to say that time is the “fourth dimension”?
2 days ago · General relativity. Tests of general relativity serve to establish observational evidence for the theory of general relativity. The first three tests, proposed by Albert Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
5 days ago · In theoretical physics, relativistic Lagrangian mechanics is Lagrangian mechanics applied in the context of special relativity and general relativity.
