Albert Einstein is one of the most recognized physicists in the world. His contributions were recognized at the time, but not to the extent they are renowned today. Einstein showed real determination in his life when he continued to work on his theories even when his colleagues called him stupid and socially challenged (Theory of Relativity). Einstein published his theory of general relativity in 1916. This theory describes the geometric relationship to gravitation and remains one of his most recognized works. General relativity combines special relativity and Newton's law of universal gravitation, which provides a unified description of gravity as a property of space-time. The theory states that the curvature of space-time is directly related to the energy of whatever matter and radiation exists in a specific location. This relationship is described by Einstein's Field equations, which are a system of partial differential equations (Theory of Relativity). Many predictions using general relativity are different from those of classical physics. General relativity predicts gravitational time dilation. This is the distortion of the speed at which time passes due to the different position of the observers relative to the gravitational masses. The closer the observer is to the source of gravity or the stronger the force of gravity on the observer, the slower time passes. This prediction has been confirmed through experiments (Theory of Relativity). General relativity also predicts gravitational redshift. Gravitational redshift or Einstein shift is a process in which the frequency of electromagnetic radiation (light) decreases as the radiation passes through a gravitational field. Redshift occurs when electromagnetic radiation... the center of the paper... and ammonia mix. The butane then flows to the coils where it evaporates and completes the refrigerator's cooling function. Einstein's final work was an effort to disprove quantum mechanics and quantum theory. He denounced this theory and thought it was invalid even though he helped create it. He announced: “God is not playing dice” because of the randomness of quantum theory. Einstein attempted to disprove quantum theory until his death in 1917 at the age of 76. He failed to invalidate quantum mechanics or theory (Albert Einstein). Einstein produced many more theories, inventions, and contributions than I have discussed. . He is one of the most prolific physicists. Albert Einstein radically changed the model of modern physics and also the way we think about the universe. His groundbreaking contributions will be permanently renowned.
