A nice visual description again. A video on "the measurement problem" and the "different interpretations of quantum mechanics (Copenhagen, Von Neumann-Wigner) could be a nice follow-up. For me, understanding why the wave function collapses and what exactly a measurement is (an interaction with a different quantum system?) is still hard.
Thanks Georg - and excellent suggestions. I was already trying to keep the current video brief, but realise I could already unpack so much more (e.g. as I have done in other videos just for the electron passing through the slits). As for why the wave function collapses and what measurement is - these are indeed tough physics research problems. Imaginatively and very non-rigorously I have found myself making a very informal analogy related to one definition of what time is: a potential infinity of future events, which pass through the present moment to just one realisation only out of the many, to a state of finality in the past.
Excellent idea - although that would constitute a measurement, and hence wavefunction collapse (no quantum superposition)! This all relates to the so-called “measurement problem” in quantum mechanics!
@@eternal6443 Exactly, making a measurement / observation somehow causes the wave function to collapse, at least according to the Copenhagen interpretation of quantum mechanics.

So we should be building our quantum computers out of arrays of cats?
I see you share Schrodinger’s own skepticism about the practical outworking of his equation!
Nice video, i play you videos when I want to sleep. lol
Thanks! So perhaps you are in a superposition of awake and asleep when you watch my videos!!
What if we put a camera inside the box!!🤔

It will require light and light is em wave , so again u r observing and causing lost information .

What is the name of the cat?
Let’s call the cat “Qubit”
