I have seen its name in many articles I have read but I would like to know. What is it and what is its use?

Roughly speaking, S.E. is an equation that governs the time-evolution of a quantum system. That is, if you know the system's state at some time and you would like to know the system's state at some later time, then you have to solve S.E.
 
OK thank you all

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
