    Undergrad Do I need energy to measure position without uncertainty?

    I do not make any further hypothesis. No. The wavefunction is before measurement. I tried to understand what the physical state of Dirac delta represents, but as King Vitamin said, Dirac delta is not a physical state. Furthermore, I am trying to understand better what happens after the wave...

    Undergrad Do I need energy to measure position without uncertainty?

    OK. So if the particle is free (with low energy) to locate it in a small region of space, my measurement must necessarily provide large energy to the particle. I understood. Very clear! Instead we now assume that the particle is already confined in a small region of space (forced by a force...

    Undergrad Do I need energy to measure position without uncertainty?

    I state the following study and then expose my doubt at the end. MY SYSTEM A free particle (absence of forces) on one-dimensional space (X axis). INITIAL STATE At t=0 the wave function is a Gaussian wave packet NOT normalizet centered in ##x_{0}## and with standard deviation ##\sigma##...

    How Can We Resolve Interpretative Errors in Quantum Mechanics?

    Greeting from Rome! I am 53 years old and I graduated in physics back in 1990, but I have always worked in the Information Technology area. I work in the IT staff of the most important Italian newspaper on economics and finance: Il Sole 24 ORE spa https://www.ilsole24ore.com/ After so many...
