I was surprised that the findings on the brain’s processing of information and discerning of relationships would come as a surprise. I have long been aware of, and have even come to count on, the fact that a surprising degree of insight and clarity often comes in the morning after having fallen asleep the night before wrestling with a complex mathematics or physics problem. I am certain that many, if not most, mathematicians, physicists, and others dealing with difficult problems are equally aware of this phenomenon.
