Latest Introduction to special relativity Stories
According to Hubble’s law, the frequency of light from distant galaxies is shifted toward the red in a way proportional to their distance D, z = HD, where H is Hubble's constant. Dr. J.
New research on the human brain suggests our movements through physical space are directly connected with how our brains perceive time.
Is it possible to move faster than the speed of light? A group of applied mathematicians at the University of Adelaide believes so, saying they have extended Einstein's theory of special relativity to work beyond the speed of light.
Microscopic objects floating in fluids move great distances at times, not just in a bell curve, disputing an Einstein theory, a U.S.
In his discussion of accelerated motion on page 60 of The Meaning of Relativity, Albert Einstein made an approximation that allowed him to develop the theory of relativity further.
He stopped traffic on Fifth Avenue like the Beatles or Marilyn Monroe. He could've been president of Israel or played violin at Carnegie Hall, but he was too busy thinking. His musings on God, love and the meaning of life grace our greeting cards and day-timers. Fifty years after his death, his shock of white hair and droopy mustache still symbolize genius. Who else could it be but Albert Einstein?
This year marks the 100th anniversary of a revolution in our notions of space and time. By measuring the shape of space with exquisite precision, NASA's Gravity Probe B aims to confirm Einstein's theory of relativity ... or provide the first evidence against it.
Spacetime -- In special relativity and general relativity, time and three-dimensional space are treated together as a single four-dimensional manifold called spacetime (alternatively, space-time; see below). A point in spacetime may be referred to as an event. Each event has four coordinates (t, x, y, z). Just as the x, y, z coordinates of a point depend on the axes one is using, so distances and time intervals, invariant in Newtonian physics, may depend on the reference frame of an...
General Relativity -- General Relativity is the common name for the theory of gravitation published by Albert Einstein in 1915. According to general relativity the force of gravity is a manifestation of the local geometry of spacetime. Although the modern theory is due to Einstein, its origins go back to the axioms of Euclidean geometry and the many attempts over the centuries to prove Euclid's fifth postulate, that parallel lines remain always equidistant, culminating with the...
