A List Apart: Articles: Designing Contracts for the XXI Century

defmacro - The Nature of Lisp
Lisp is a way to escape mediocrity and to get ahead of the pack. Learning Lisp means you can get a better job today, because you can impress any reasonably intelligent interviewer with fresh insight into most aspects of software engineering. It also means you're likely to get fired tomorrow because everyone is tired of you constantly mentioning how much better the company could be doing if only its software was written in Lisp. Is it worth the effort? Everyone who has ever learned Lisp says yes. The choice, of course, remains yours.

Why Lucky Charms Sometimes Work: The Powerful Positive Performance Psychology Of Superstition
In a test conducted by researchers from the University of Cologne, participants on a putting green who were told they were playing with a “lucky ball” sank 6.4 putts out of 10, nearly two more putts, on average, than those who weren’t told the ball was lucky. That is a 35% improvement. The results suggest new thinking in how to view luck and are intriguing to behavorial psychologists.

Gödel's incompleteness theorems

Gödel's incompleteness theorems - Wikipedia, the free encyclopedia
The first incompleteness theorem states that no consistent system of axioms whose theorems can be listed by an "effective procedure" (e.g., a computer program, but it could be any sort of algorithm) is capable of proving all truths about the relations of the natural numbers (arithmetic). For any such system, there will always be statements about the natural numbers that are true, but that are unprovable within the system. The second incompleteness theorem, a corollary of the first, shows that such a system cannot demonstrate its own consistency.
