Quantum Mechanics is a branch of physics that studies the behavior and properties of energy and matter at the atomic and subatomic level. It is a complex field of study that deals with the behavior of particles that are too small to see with the naked eye. To make it easier to understand, let’s use an example. Imagine you have a box with two slots, one labeled “up” and the other labeled “down”. Inside the box, there is a particle that can be in either of the two states, either up or down. According to quantum mechanics, the particle does not have to be in just one state. It can be in both states at the same time. This phenomenon is called quantum superposition. Another interesting aspect of quantum mechanics is entanglement. This is a phenomenon in which two particles are linked and the state of one particle affects the state of the other, regardless of the distance between them. Fun fact: Quantum Mechanics has applications in various fields, such as cryptography, computing and medicine.
