Quantum superposition is a fundamental principle of quantum mechanics that states that linear combinations of solutions to the Schrödinger equation are also solutions of the Schrödinger equation. This follows from the fact that the Schrödinger equation is a linear differential equation in time and position. More precisely, the state of a system is given by a linear combination of all the eigenfunctions of the Schrödinger equation governing that system..

Slovákov z nás urobili Česi.
Aj tým, že sme skončili v jednej republike, aj tým, že bol tlak na akýsi československý národ, čo sa nám nepáčilo, ale hlavne tým,
že nás mali radi."
