Quantum physics

by Alessio Mangoni

Quantum physics has upset the way of thinking of many scientists, convinced, at the beginning of the twentieth century, that they understood all the fundamental principles that govern nature. The greatest certainties gained by science in previous centuries began to waver in the face of new discoveries that literally revolutionized modern physics, including Einstein's relativity who practically reformulated Newton's laws, redefining the underlying background, and the advent of quantum mechanics. The latter has also changed the certainties that seemed definitive, with the introduction of the probability density of the presence of a particle and its consequences, such as the tunnel effect, and with the famous Heisenberg uncertainty principle, all concepts that go against common sense. To explain the experimental results obtained by observing the microscopic world, it was necessary to formulate new theories to overcome the failure of the classic ones which were formulated by observing nature only from the macroscopic point of view.
