Quantum mechanics is the branch of physics that studies the behavior of matter and energy in the presence of an observer. It is the foundation of modern physics and the theory of the wave-particle duality.
In quantum mechanics, the behavior of particles is described by the wave-particle duality. This means that particles can exhibit both wave-like and particle-like behavior, depending on the experiment being performed.
The wave-like behavior of particles is described by the wave function, which is a mathematical function that describes the probability of finding a particle at a certain point in space. The wave function is used to calculate the probabilities of various outcomes of an experiment.
The particle-like behavior of particles is described by the Heisenberg uncertainty principle. This principle states that certain properties of particles, such as momentum and position, cannot be known simultaneously with absolute certainty.
Quantum mechanics is essential for understanding the behavior of physical systems at the atomic and subatomic level. It is also necessary for the development of technologies like lasers and transistors.
