Hi guys,

is there a reason why the energy of the harmonic oscillator is always written as:$$
E_{n} = \hbar \omega (n + \frac{1}{2})$$
instead of :
$$
E_{n} = h \nu (n + \frac{1}{2})$$
?

It means the same, usually QM uses hbar to avoid the 2pi appearing everywhere.
 
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles.

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!
