This video starts out with an intriguing barber paradox, and uses this as an analogy to a computer program, and then outlines a proof by contradiction to say that such a program cannot exist. Then, functions are discussed in some detail. Next, some more about complexity with Big O and Big Theta are reviewed. Some really interesting and complex sums of series are calculated.
