The engine driving the Kelly system is the "law of large numbers." In a 1713 treatise on probability, Swiss mathematician Jakob Bernoulli propounded a law that has been misunderstood by gamblers (and investors) ever since.

There is a deep connection between Bernoulli's dictum and John Kelly's 1956 publication. It turns out that Kelly's prescription can be restated as this simple rule: When faced with a choice of wagers or investments, choose the one with the highest geometric means of outcomes.

In his book Scientific Edge, noted physicist Jayant Narlikar stated that "Srinivasa Ramanujan, discovered by the Cambridge mathematician G.H. Hardy, whose great mathematical findings were beginning to be appreciated from 1915 to 1919. His achievements were to be fully understood much later, well after his untimely death in 1920. For example, his work on the highly composite numbers (numbers with a large number of factors) started a whole new line of investigations in the theory of such numbers." Narlikar also goes on to say that his work was one of the top ten achievements of 20th century Indian science and "could be considered in the Nobel Prize class." The work of other 20th century Indian scientists which Narlikar considered to be of Nobel Prize class were those of Chandrasekhara Venkata Raman, Megh Nad Saha and Satyendra Nath Bose.

Pythagoras, as everyone knows, said that "all things are numbers." This statement, interpreted in a modern way, is logical nonsense, but what he meant was not exactly nonsense. He discovered the importance of numbers in music and the connection which he established between music and arithmetic survives in the mathematical terms "harmonic mean" and "harmonic progression." He thought of numbers as shapes, as they appear on dice or playing cards. We still speak of squares or cubes of numbers, which are terms that we owe to him. He also spoke of oblong numbers, triangular numbers, pyramidal numbers, and so on. These were the numbers of pebbles (or as we would more naturally say, shot) required to make the shapes in question.

As one of the handful of girls who worked with both of those dance geniuses, I think I can give an honest comparison. In my opinion, Kelly is the more inventive choreographer of the two. Astaire, with Hermes Pan's help, creates fabulous numbers - for himself and his partner. But Kelly can create an entire number for somebody else... I think, however, that Astaire's coordination is better than Kelly's... his sense of rhythm is uncanny. Kelly, on the other hand, is the stronger of the two. When he lifts you, he lifts you!... To sum it up, I'd say they were the two greatest dancing personalities who were ever on screen. But it's like comparing apples and oranges. They're both delicious.

"Driving is boring," Rabbit pontificates, "but it's what we do. Most of American life is driving somewhere and then driving back wondering why the hell you went."
