History of Quantum Mechanics
The properties of Quantum Physics are very different from those of Classical Physics, which describes nature on our scale. It is mainly characterized by not being deterministic but probabilistic. Furthermore, Energy inbound systems (i.e., atoms) are not exchanged continuously but rather discreetly, which implies the existence of minimal energy packages, called quanta
Quantum Mechanical Phenomena
- The phenomenon of superposition: It tells us that an electron can be present at the same time in your house, on the highest peak of Everest, or on the surface of Jupiter. That is, a particle is present in many places at the same time with different probabilities, as long as it is not observed.
- The phenomenon of entanglement: It tells us that an electron found in our computer may be entangled with another electron located on a distant planet 400 light-years away. When we modify the state of one of the electrons, the other changes instantly.
- The tunnel effect: It tells us that an electron can sometimes pass through walls or thin walls of energy as if it were a ghost. This is due to the wave-particle duality, which quantum mechanics confirms.
