The Quantum Mechanics are weird, yet incredibly powerful theory of the subatomic world, in which everyday concepts to do with the forces and motion are seen in a different perspective, as they do not longer apply in the same way. This calls for a new type of mechanics based on what scientists call "quantum" rules.
Quantum mechanics are a very complicated matter that scientists don't fully understand yet; they are in charge of studying the smallest faces of our world. The idea of quantum mechanics was developed in the 20th century by a German physicist Max Planck who introduced his constant, called Plank´s Constant (h=6.62606957×10-34 m2 kg/s), which is used to determinate the energy of a photon. When E=hv (v=frequency). Albert Einstein, Niels Bohr, Paul Dirac and Werner Heisenberg later extended the theory in the 1920s.
Trying to explain quantum mechanics is like trying to explain how the universe was formed. There are different doctrines but again, none of them is completely certain.
Although it was a tremendous success to the researchers no one really knows how or why it works. It makes prediction in the microscopic world that go completely against our common sense. For example quantum mechanics state that an atom can be in more than 1 place at the same time until we look at it, since then we force it to make a choice on where he is. Also assures that an atom is neither a particle nor a wave, it is both and neither at the same time. All these weird statements are worked today by physics. But they are still a mystery.
The Quantum Mechanics, mainly study the behavior of particles. In my opinion, however, one of the greatest topics in the subatomic world is the behavior of the electrons. We all know that electrons repel each other, as a result of both having the same charge (-). Also we all know that everything is made out of atoms, which their outer particles are the electrons.
Going back to the quantum theories, you have never touched anything in your life. What we perceive as touch is just our brain's way of telling us that we are interacting with a strong electromagnetic field, created by the electrons´ force of repulsion. It turns out that this repulsive force is so strong that no matter how hard you try the molecules in your body to touch something, they will never make contact with molecules in another substance.
If you were able to zoom in to the subatomic level to take a closer look at the objects you think are touching, you'd see none of them are touching at all. We simply feel the repulsive force between these electrons, and interpret it as touch... So you´ve always been fooled. Well kind of, the expression "touch" is defined by...
