Quantum teleportation, contrasting the classical and quantum mechanics descriptions, classical physics.
Improving students understanding of quantum mechanics. The author avoids the temptation to include every possible relevant topic, instead presenting students with material. Chapter 6 also demonstrates that thermodynamics is a straightforward consequence of quantum mechanics and that we no longer need to derive the laws of thermodynamics through the traditional, rather subtle, arguments about heat engines. Fortunately for nmr spectroscopists, the quantum mechanics of nuclear spins is quite straightforward and many useful calculations can be done by hand, quite literally on the back of an envelope.

By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the moon. An essential step in the attempts tosolve these problems was made by everett in its famous manyworlds interpretation of quantum mechanics 1, 2. It explains the behavior of matter and its interactions with energy on the scale of atoms and subatomic particles.
