It is probably a silly question but I just wanted to clear it out...

Is the uncertainty principle valid for small particles because we can't find something less energetic/massive to probe the observables ... ?

For example if we find a way to probe let say electron firing neutrino at it (it is million times smaller), will this make the system describable by semi-classic formulas ...
OR uncertainty is valid no matter how small probe we get..

Er... the HUP is also valid for something as big as a buckyball. "Size" has nothing to do with this. We can certainly find something smaller than a buckyball to probe it.

uncertainty has nothing to do with measurement ... it is fundamental to quanta
 
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!
