It is a study of queues. A typical example is one that may be found in banks. Customers arrive at intervals that are determined by some probability distribution function. There are then two possible queueing scenarios: one in which there is a single queue which feeds into several cashiers or a system where there are multiple queues: one for each cashier. When a customer reaches a cashier, it takes the cashier an amount of time to serve him or her. This time also has a probability distribution function - different from the one governing arrival times.
The theory studies the optimum queueing scenario, time spent by customers in queues rather than being served, the optimum number of cashiers. The bank must find the best trade-off between the cost of employing more cashiers and the irritation of their customers.

What is Godel's incompleteness theory?
Gödel's incompleteness theorem was a theorem that Kurt Gödel proved about Principia Mathematica, a system for expressing and proving statements of number theory with formal logic. Gödel proved that Principia Mathematica, and any other possible system of that kind, must be either incomplete or inconsistent: that is, either there exist true statements of number theory that cannot be proved using the system, or it is possible to prove contradictory statements in the system.

How is a theory different from a guess?
A "theory", as the word is used in science, is not just a guess; it's refers to a system of thought that is well-established, and confirmed by numerous experiments. For example, the "Theory of Relativity" or the "Big Bang theory" are more than wild guesses; there are strong reasons to believe in each of them, including the results of numerous experiments.For more information, read the article on "Scientific theory", in the Wikipedia - or at least the introductory paragraphs.
