Why is the minimum energy equal to the energy uncertainty?
I was watching this video on Youtube, however, I don't get the step at 14:50 where he says that ΔE≥½hf means that E0=½hf.

Could someone explain why the minimum energy is equal to the energy uncertainty?

"Watch this obviously confusing video and then explain it to me" is a big, big ask.

It's not.

It's just saying that, since the energy of any state whatever must be greater than or equal to ##hf / 2##, the energy of the lowest energy state, the ground state energy ##E_0##, is equal to ##hf / 2##.

That's not what the above is saying.

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. Towards the end of the first lecture for the Qiskit Global Summer School 2025, Foundations of Quantum Mechanics, Olivia Lanes (Global Lead, Content and Education IBM) stated...

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!
