He retired from teaching in order to develop their theoretical research exclusively. Albert Einstein and the theory of relativity The theory of relativity, developed primarily by Albert Einstein, intended originally to explain certain anomalies in the concept of relative motion, but in its evolution has become one of the most important theories in the physical sciences, and has been the basis for physicists to demonstrate the essential oneness of matter and energy, space and timeand the equivalence between the forces of gravitation and the effects of the acceleration of a system.
Albert Einstein The theory of relativity as Einstein put it had two different formulations. The first is that which corresponds to two papers published in in the Annalen der Physik. It is known as the theory of special relativity and deals with systems that move one with respect to the other with constant speed and may be even equal to zero.
The second, called general relativity theory this is called the work of at which made itdeals with systems moving at variable speed. Special relativity theory The postulates of special relativity are two.
The first says that all motion is relative to anything else, and therefore the ether, which had been considered during the 19th century as average propagator of light and the only thing quite firmly of the universe, with absolute movement and not determinable, was out of place in physics, since no longer is it needed such media whose existence effective In addition, not had been able to determine by any experiment.
The second postulate asserts that the speed of light is always constant with respect to any observer. Of their theoretical premises obtained a series of equations that had important consequences and even some disconcerting, as the increase of the mass with speed.

Particle accelerators, which gets an increase in mass, are clear experimental proof of the theory of special relativity. The theory also States that in a system moving with respect to an observer is verified a dilatation of the time; put another way, time passes more slowly in the system in motion.
This is clearly illustrated by the famous twins paradox: Theory of general relativity The theory of general relativity refers to the case of movements that occur with variable speed and has as a fundamental postulate the equivalence principle, according to which the effects produced by a gravitational field are equivalent to those produced by the accelerated movement.
The revolutionary hypothesis formulated by Einstein was caused by the fact that the theory of special relativity, based on the principle of the constancy of the speed of light which is the movement of the reference system which is measured as was demonstrated in the experiment of Michelson and Morleydoes not match the theory of Newtonian gravitation: If the force with which two bodies are attracted depends on the distance between them, to move one should change instantly the Force felt by the other, i.
After several failed attempts to accommodate the gravitational interaction with relativity, Einstein suggested that gravity is not one force as the other, but it is a consequence that space-time is warped by the presence of mass or energy, which is the same.
Then, bodies like the earth does not move in closed orbits because there is a force called gravity, but they move in as close to a straight line, but in a spacetime which is distorted by the presence of the Sun.
Einstein in his Studio c. However, in contrast to Minkowski space and because of the gravitational field, this universe is not Euclidean. Thus, the distance between two adjacent points of space-time in this universe is more complex than in the Minkowski space. Planetary orbits very similar to that obtained with the mechanics of Newton are obtained with this theory.
An effect that early corroborated the theory of general relativity is the deflection that suffer the rays of light in the presence of gravitational fields.Criticism of the theory of relativity of Albert Einstein was mainly expressed in the early years after its publication in the early twentieth century, on scientific, pseudoscientific, philosophical, or .
Watch video · Albert Einstein (March 14, to April 18, ) was a German mathematician and physicist who developed the special and general theories of relativity. In , he won the Nobel Prize for physics for his explanation of the photoelectric effect. Einstein's Blackboard is a blackboard which physicist Albert Einstein (–) used on 16 May during his lectures while visiting the University of Oxford in England.
The blackboard is one of the most iconic objects in the collection of the Museum of the History of Science in Oxford.
Albert Einstein was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics.
For this achievement, Einstein is often regarded as the father of modern physics, and one of the most prolific intellects in human history. Albert Einstein was a German-born physicist who developed the general theory of relativity.
He is considered one of the most influential physicists of the century. . Theory of Relativity and the Special Theory of Relativity by Albert Einstein Particularly, the General Theory of Relativity describes the curvature of space and time as directly related to the energy and momentum of whatever matter and radiation are present.
