Albert Einstein is one of the most recognized physicists in the world. His contributions in his time were recognized, but not as much as they are today. Einstein showed true determination in his life when he continued to work on his theories even when his peers called him stupid and socially handicapped (Theory of Relativity). Einstein published his theory of general relativity in 1916. This theory describes the geometric relationship with 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 spacetime. The theory states that the curvature of space-time is directly related to the energy of matter and radiation present at 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 rate at which time passes because observers are located differently from gravitational masses. The closer the observer is to the source of gravity or the stronger the force of gravity is on the observer, the slower time passes. This prediction was confirmed by experiments (Theory of Relativity). General relativity also predicts gravitational redshift. Gravitational redshift or Einstien 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...... middle of paper ......ter and ammonia mix. The butane then flows to the coils where it evaporates and completes the cooling function of the refrigerator. Einstein's final work aimed to disprove quantum mechanics and theory. He denounced this theory and deemed it invalid even though he helped create it. He announced, “God doesn’t play 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 mechanics or quantum theory (Albert Einstein). Einstein produced many more theories, inventions and contributions than those I have discussed. . He is one of the most prolific physicists. Albert Einstein fundamentally changed the model of modern physics as well as the way we think about the universe. His revolutionary contributions will be lastingly recognized.
