Quantum Mechanics and Immortality

[color=rgba(0, 0, 0, 0.97)]Quantum Mechanics is a curious area of study which began in the early 20th century when scientists began to discover that the theories of electromagnetism and Newtonian mechanics, which so elegantly describe the movements of normal objects, completely fell apart at extremely tiny atomic and subatomic scales. It soon became clear that a separate theory would be necessary to describe subatomic interactions, and thus Quantum Mechanics was born.

[color=rgba(0, 0, 0, 0.97)]The theory of quantum mechanics describes a tiny realm completely foreign to the one we observe normally. At quantum levels, matter exists simultaneously as particles and as waves (wave-particle duality), a particle’s position and momentum cannot be precisely known at the same time (Heisenberg uncertainty principle), and the state of two objects can be intertwined, regardless of the physical distance between them (quantum entanglement). Niels Bohr, one of the fathers of quantum mechanics, once said, “Anyone who is not shocked by quantum theory has not understood it.”

[color=rgba(0, 0, 0, 0.97)]The predictions of quantum mechanics have never been disproved in any experiments in over a century of development. It has been studied by brilliant minds including Albert Einstein and Richard Feynman, and though there is much disagreement about what it all means, there is little doubt that it is true. Some even think it provides us with a means to live forever.

[color=rgba(0, 0, 0, 0.97)]Quantum mechanics is not in the business of exact predictions, rather it deals in probabilities when describing the position or momentum of a given particle at a certain time. This inexactness is not because the theory is incomplete, but because those qualities of a particle are inherently unpredictable with any precision; or to put it another way, because there seems to be some degree of randomness at play in the universe. Einstein was famously uncomfortable with this facet of quantum physics, asserting that “God does not play dice!” But despite spending a good deal of his life after 1925 trying to back up his assertion, he was never able to.

[color=rgba(0, 0, 0, 0.97)]In 1957, a student named Hugh Everett suggested that perhaps the reason that a particle’s outcome can’t be predicted is not because of randomness, but because every possible outcome does occur. This idea led to the “many-worlds interpretation” (MWI) which postulates that at the quantum level, everything that can happen does happen, and that each possible outcome branches the universe into another which is at first identical aside from the alternate outcome. So the seemingly “random” outcome is actually just representative of the one possible outcome one’s current universe happens to be based upon. The overlapping universes, between which no information can pass, would then continue to develop individually, each of them branching endlessly as well. Among physicists worldwide, this “multiverse” idea has become one of the most widely accepted interpretations of quantum physics.

You reminded me of my physics teacher)) He often said that physics is the main science and we should know it very well)) But ... life has shown that this is not entirely true. I myself went to university to study English literature. I never needed physics later on. My younger brother was of a more down-to-earth nature and did not waste time at university. He completed courses in ventilation systems specialist. You can see his curriculum on this webpage. He knows the basics of physics but not quantum physics)) This guy has become more successful than me. He runs his own home systems service firm. It all depends on the person's purpose in life. You agree with me?

[/Quote] I'm a little jealous of those who are well versed in this topic. However, physics and mathematics are bad for me. I realized this back in high school when I had to order such assignments from writemyessayquick.net  My vocation is a sculpture. I graduated from art college)) Luckily for me, the lack of knowledge of quantum mechanics does not affect my talent in any way)
