What is quantum mechanics?
The term quantum mechanics (QM) generally concerns the mathematical formulation of quantum theory. Quantum mechanics often describe and predict the movement and behavior of particles at the atomic and subatomical levels. These include particles such as atoms, electrons, protons and photons. According to quantum mechanics, the behavior and movement of particles on these microscopic levels are contrainuitive, radically different from everything observed in everyday life. This requires a theory such as quantum mechanics to better explain this different world. The particles can be considered located, transporting matter and energy in their movement. Waves are a type of phenomenon that is never located and has no matter but still carries energy. Mikro-light particles that are examined in quantum mechanics macro-world, because in certain situations particles can act as waves, while the waves can act as particles. According to quantum mechanics, this would mean that on quantum level Apple could act like a wave while the wavecould act like an apple.
The quantum mechanics uses a quantum unit to assign and measure the amount of physical properties of these particles. The particles are generally measured by considering the wave function recorded at the time of the measurement. However, because particles can act like waves, the current position or speed of the particle can never be completely determined.
This apparent puzzle is known as Heisenburg's principle of uncertainty, which in other words states that the position and momentum cannot be measured exactly at the same time. This is not exactly because there are restrictions on measuring equipment or ability, but because it is assumed that this uncertainty is the particles itself. Quantum mechanics is therefore a mathematical theory that tries to calculate the likelihood according to the function of the wave.
Many scientists disagree with the postulates of quantum mechanics. Albert Einstein was a scientist who was sometimes critical of quantum theory because he was contrary toHis own theory. Thus, one of the greatest problems in contemporary physics is to create a theory that would unify the ideas of quantum mechanics with those of Einstein's general theory of relativity. Physicists such as Julian Barbar have proposed some innovative solutions to this problem, in principle, stating that if people consider that there is no time, there is no obstacle to the unification of quantum mechanics and the theory of relativity.
