  • 03:22: They only gain specific values when  observed and the wavefunction “collapses”.

2021-08-10: How to Communicate Across the Quantum Multiverse

  • 02:29: ... For example there’s the Copenhagen Interpretation, which says that the wavefunction collapses at the point of measurement, leaving only one reality; or de ...

2021-07-13: Where Are The Worlds In Many Worlds?

  • 05:22: ... of quantum mechanics - the Copenhagen Interpretation - tells us that the wavefunction “collapses” - it instantaneously shrinks from encompassing a huge range of possible ...

2021-03-23: Zeno's Paradox & The Quantum Zeno Effect

  • 02:52: In the language of the Copenhagen interpretation of quantum mechanics, we say that the “wavefunction collapses” on observation.

2020-12-08: Why Do You Remember The Past But Not The Future?

  • 13:47: ... and at any rate invoking random collapse doesn’t tell you why the wavefunction collapses in one direction and not the ...

2020-02-24: How Decoherence Splits The Quantum Multiverse

  • 00:35: ... measurement problem - the question of why and where the blurry quantum wavefunction collapses into well-defined measurement ...

2020-02-18: Does Consciousness Influence Quantum Mechanics?

  • 03:20: ... tells us that when we make that measurement the wavefunction “collapses” - it goes from a cloud of possible final destinations for the electron ...
  • 07:38: So there’s the conflict - different observers say the wavefunction collapses at different times.
  • 11:24: You talk to each other and agree that you observed the same result - the wavefunction collapses in the same way for both of you.
  • 03:20: ... tells us that when we make that measurement the wavefunction “collapses” - it goes from a cloud of possible final destinations for the electron to ...
