Packet 4: Bonus 5

According to the Born rule, the square of the modulus of this object gives a probability density function. For 10 points each:
[10m] Name this mathematical object denoted psi that represents a particle’s quantum state in quantum mechanics. This object’s namesake “collapse” occurs upon measurement.
ANSWER: wavefunction [accept wavefunction collapse]
[10h] This interpretation of quantum mechanics posits that wavefunctions never collapse, but rather every possible outcome occurs in different timelines when an experiment is conducted.
ANSWER: many-worlds interpretation [or MWI; accept Everett interpretation; accept relative-state formulation or many-universes interpretation; accept theory of the universal wavefunction]
[10e] By positing both outcomes happen in different universes, the many-worlds interpretation resolves this scientist’s thought experiment about a cat that is both alive and dead.
ANSWER: Erwin Schrödinger [accept Schrödinger's cat]
