Reading assignment: Lindley, Act III (pgs. 155-226); Also, please try to reread the second part of the Haroche article.


Please provide brief answers to the following:


1) What is the difference between a mixture and a superposition?


2) If the basic laws of physics are the same for both forward and backward time, why do we experience a definite direction of time?


3) What is decoherence?


4) How does decoherence "solve" the measurement problem?



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