Einstein's special theory of relativity explains how energy and mass are related and how objects seem to behave as they approach the speed of light. Learn to define Einstein's theory of relativity, and use examples to explain the speed of light and Einstein's mass-energy equivalence equation ...
I. BREAKDOWN OF OLDER THEORIES.—The older electromagnetic theory of moving bodies did not agree with experiment, or even with itself. For example, the theory of a magnet moving in a straight line towards a fixed conductor gave results quite different from those of the theory of a conductor ...
the“theory of relativity(相对论)". “Imagination is more important than knowledge," said Einstein.Daydreaming, called "thought experiments"by Einstein, can make you have wild imagin-ation, like flying around in space. It lets your mind walk slowly around ideas, memories and experiences that ar...
Electromagnets work via relativity as well. When a direct current of electric charge flows through a wire, electrons drift through the material. Ordinarily, the wire would seem electrically neutral, with no net positive or negative charge, because the wire has about the same number of protons (p...
A fine example is the famous Kinetic Theory of Maxwell. ... The theory of relativity by Einstein, quite apart from any question of its validity, cannot but be regarded as a magnificent work of art.Responding to the toast, 'Science!' at the Royal Academy of the Arts in 1932.) ...
Special and general relativity come together to show how time is measured differently in different frames of reference, called time dilation. This effect happens becausedifferent frames of reference perceive time and space differently. Let’s look at an example: themuon. Muons are subatomic particles...
Gravity - Fields, Relativity, Theory: In Einstein’s theory of general relativity, the physical consequences of gravitational fields are stated in the following way. Space-time is a four-dimensional non-Euclidean continuum, and the curvature of the Riema
Over time, however, the predictions of special relativity have been shown to be true. For example, clocks flown around the world have been shown to slow down by the duration predicted by the theory. Origins of Lorentz Transformations Albert Einstein didn't create the coordinate transformations nee...
a physical theory of relativity based on the assumption that the speed of light in a vacuum is a constant and the assumption that the laws of physics are invariant in all inertial systems
Einstein's Special Theory of Relativity is based on two postulates: Inertial frames in uniform relative motion are equivalent and the speed of light is the same in all of them.
