Reading assignment: Lindley, Act I (pgs. 1-83)


Please provide brief answers to the following:


1) Why does Lindley claim that the statement, "measurement affects the thing measured", is true for classical measurements but is actually misleading in the case of quantum measurements?


2) What is a delayed choice experiment?


3) Who is "Wigner's friend" and what issues does this hypothetical character raise in the measurement question?


4) Lindley claims (pg. 47) that "an electron by itself is not described by one unique wavefunction ... the wavefunction you use depends on what you plan to measure".   Do you agree with this statement?  (Look back at Nick Herbert's discussion of quantum measurement on pgs. 105-106 in "Quantum Reality").



Everyone also needs to send me a specific question you had about the reading.
