Days later, Cliff Pickover highlighted a curious factoid: When Nash wrote his . thesis in 1950, "Non Cooperative Games" at Princeton University, the dissertation (you can read it online here) was brief. It ran only 26 pages. And more particularly, it was light on citations. Nash's diss cited two texts: One was written by John von Neumann & Oskar Morgenstern, whose book, Theory of Games and Economic Behavior (1944), essentially created game theory and revolutionized the field of economics; the other cited text, "Equilibrium Points in n-Person Games," was an article written by Nash himself. And it laid the foundation for his dissertation, another seminal work in the development of game theory, for which Nash won the Nobel Prize in Economic Sciences in 1994 .
There were similar developments in many other continental European universities, and at least until reforms in the early 21st century many European countries (. Belgium, Spain, and the Scandinavian countries) had in all faculties triple degree structures of bachelor (or candidate) − licentiate − doctor as opposed to bachelor − master − doctor; the meaning of the different degrees varied a lot from country to country however. To this day this is also still the case for the pontifical degrees in theology and canon law: for instance, in Sacred theology the degrees are Bachelor of Sacred Theology (STB), Licentiate of Sacred Theology (STL), and Doctor of Sacred Theology (STD), and in Canon law : Bachelor of Canon Law (JCB), Licentiate of Canon Law (JCL), and Doctor of Canon Law (JCD).
