Unlike the last episode, which seemed to me to be very biased toward Brian Greenes particular personal view on Quantum physics, this episode is more about the core theories, and is very informative, although still leans toward Brians particular viewpoints (understandable as the episodes are based on his book).
For some good descriptions of where quatum theories come from, this is one to watch, but beware of only taking Brians views of what these theories and experiments mean. Think about what they mean yourself.
Quantum physics is drowning in people that accept a viewpoint without even understanding it, and there is an scandalous lack of original thinkers who have the mind and the strength of character to be able to stand up and question fashionable theories.
This can be seen in this episode where leaders in the field actually openly state that they don't understand why, but the equations work. Far too many are working by little more than rote *see lower.

Main article: Rote learning
Rote learning is a technique which avoids understanding the inner complexities and inferences of the subject that is being learned and instead focuses on memorizing the material so that it can be recalled by the learner exactly the way it was read or heard. The major practice involved in rote learning techniques is learning by repetition, based on the idea that one will be able to quickly recall the meaning of the material the more it is repeated. Rote learning is used in diverse areas, from mathematics to music to religion. Although it has been criticized by some schools of thought, rote learning is a necessity in many situations.
