The essence of Albert Einstein's world is linked to the concept of relativity. He describes it this way: \u201cWhen you sit next to a nice girl for two hours, it seems like only two minutes have passed. When you sit on a hot stove for two minutes, it seems to you that it has been two hours; this is relativity. Einstein dares to establish that there are no absolute quantities, that the magnitude of the quantities depends on the relative speed between an object and the observer, and that each event and measurement is seen differently depending on the relative speed between an object and the observer. observer. However, the only measurement that remains constant is the speed of light C in a vacuum. The amazing results of his special Theory of Relativity indicated that if an object has a speed close to the speed of light, then:<\/p>\n\n\n\n

    \n
  1. It would appear shorter, or the thickness would become smaller, while at the speed of light it would appear to be of zero length or thickness.<\/li>\n\n\n\n
  2. The passage of time for the object would appear to be shorter than what we would see;<\/li>\n\n\n\n
  3. As the object gets closer and closer to the speed of light it begins to gain energy and therefore mass: if it reached the speed of light it would have infinite mass (and energy).<\/li>\n<\/ol>\n\n\n\n

    All these propositions are shown through art with the following paintings.<\/p>\n\n\n

    The Persistence of Memory<\/em>, by Salvador Dal\u00ed (1904-1989), shows the ability to lengthen time. The soft clocks in the painting create a sensation of stretching out time, and consequently a time interval, say a second, would stretch to infinity if an identical clock had been traveling at the speed of light.<\/p>\n\n\n\n

    <\/p>\n\n\n\n

    Another example of lengthening time is shown in the figure.<\/p>\n\n\n

    Using Einstein images. If he had moved at the speed of light he would have stayed the same age, say 33 years. However, a normal life in the universe causes him to age, as shown on the right hand side of this figure.<\/p>\n\n\n\n

    The painting of the listening room, by the Belgian surrealist artist Ren\u00e9 Magritte (1898-1967), can serve to illustrate the behavior of the mass with speed. . The work shows how the size of the apple approaches infinity, as predicted by Einstein's theory.<\/p>\n\n\n\n

    Magritte's Glass House shows the result of the speed of light and the thickness becoming zero: the back of the head is practically transparent. On the right side, the head is restored to its normal condition.<\/p>\n\n\n\n

    The following illustration shows the Einstein equivalence energy (E) \u2013mass (m), whereby mass is transformed into energy according to the expression E=mC2, as in the atomic bomb. In physics, mass-energy equivalence means that the mass of a hide is a measure of its energy content. According to this concept, the total internal energy of a body at rest is equal to the product of its rest mass m and a suitable conversion factor C to transform mass units into energy units. On the left side of this figure, Magritte's The Pleasure Principle gives the impression of energy; and on the right side, the image of Einstein has been placed on the original painting to show the concept of mass.<\/p>\n","protected":false},"excerpt":{"rendered":"
