Albert Einstein is the author of the theory of relativity, and he is known as a genius in history, also is the symbol of the scientific revolution of the twentieth century. What did Albert Einstein contribute to science? As stated by Russell:
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.
Einstein in the laboratory of Pieter Zeeman Amsterdam, c. Particle accelerators, which gets an increase in mass, are clear experimental proof of the theory of special relativity.
1. Einstein relied on friends and colleagues to help him develop his theory. Though the theory of general relativity is often presented as a work of solo genius. Albert Einstein Biography Albert Einstein was a physicist, born in Ulm, Germany, on March 14, Albert Einstein is the author of the theory of relativity, and he is known as a genius in history, also is the symbol of the scientific revolution of the twentieth century. With his general theory of relativity, Albert Einstein is the symbol of genius. Being honored with the Nobel Prize in physics made him famous and firmed-up his reputation as a genius. Though Albert Einstein is remembered mostly as being a scientist, he was also concerned with helping people.
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. One of the points of disagreement between the two, the abnormally elongated orbit of the planet Mercury, which has an effect of rotation of the major axis of the ellipse approximately one degree every ten thousand yearshad been experimentally observed some years before stated the theory of relativity, and could not be explained with Newton's laws.
The described orbit, however, fulfilled predictions relativistic, thus serving as experimental confirmation of Einstein's 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. Light rays, going from a region of a gravitational field to another, should suffer a shift on its wavelength the gravitational red shift or displacement of Einsteinwhich was proven by measuring the displacement of a star, with respect to a group of stars taken as reference, apparent when light rays from it brushed the Sun.
Displacement of Einstein To avoid the glare of the observer by the Sun's rays, verification was conducted using a total solar eclipse that took place in The star was photographed twice, one in absence and in presence of the eclipse.
Thus, by measuring the apparent displacement of the star with respect to the reference stars, was obtained Deflexion angle which turned out to be very close to that Einstein envisioned.
The concept of time was deeply affected by general relativity. A surprising result of this theory is that time must elapse slower much stronger is the gravitational field in which it is measured. This prediction was also confirmed by experience in In fact, many modern satellite navigation systems take into account this effect, since otherwise they would give errors in the calculation of the position of several kilometers.
Another surprising deduction of Einstein's theory is the phenomenon of gravitational collapse which gives rise to the creation of black holes, concentrations of mass in such high density that its force of gravity traps even light.
Since the gravitational potential is non-linear, to becoming the order of the square of the speed of light you can grow indefinitely, appearing a singularity in solutions. The study of black holes would become in few years in one of the research areas of increased activity in the field of cosmology; Perhaps it would be the center of interest of the fruitful hypothesis of another distinguished physicist, Stephen Hawking.The theory of general relativity has a fundamental law—the Einstein equations which describe how space curves, the geodesic equation which describes how particles move may be derived from the Einstein lausannecongress2018.comal advisor: Alfred Kleiner.
Albert Einstein's challenging theoretical explanations of the deepest workings of the universe had been vindicated in the most dramatic possible way, with the publication of definitive photographs made possible only by the rarest of celestial events, a .
Relativity: The Special and the General Theory began as a short paper and was eventually published as a book written by Albert Einstein with the aim of giving: "an exact insight into the theory of relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant 4/5().
Success and the General Theory of Relativity Einstein was only somewhat satisfied with the Entwurf paper and, by , he had come to the realization that the Entwurf theory was flawed. Ever persistent, Einstein returned to a mathematical strategy.
