Have fun touring the chapter.

Answer the following questions to earn up to 5 points extra credit:

• What is the approximate temperature In the universe in the space between galaxies?
• What was the approximate temperature of the first BEC, produced by Eric Cornell and Carl Wieman in Boulder, Colorado in 1995?
• In a few sentences describe the sequence of processes that were used to cool the atoms, so that a BEC would form.
• Were you able to slow down and trap atoms using the laser beam simulations?
• What is the purpose of the magnetic field?

We have mentioned some of the implications of quantum entanglement in module 3.  The next two assignment invite you to explore further.
