PreClass_12 (email me your answers by 12 noon Tuesday ... taylormp@hiram.edu)

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.
