Ars Conjectandi

"The art of measuring, as precisely as possible, probabilities of things, with the goal that we would be able always to choose or follow in our judgments and actions that course, which will have been determined to be better, more satisfactory, safer or more advantageous..."
–Ars Conjectandi, Chapter II, Part IV, defining the art of conjecture.


FIRST EDITION OF BERNOULLI'S FOUNDATIONAL WORK ON PROBABILITY THEORY. PMM 179.

Jakob Bernoulli's "great treatise (conjectandi) means literally 'casting', sc. dice) was published posthumously. It was the first systematic attempt to place the theory of probability on a firm basis and is still the foundation of much modern practice in all fields where probability is concerned - insurance, statistics and mathematical heredity tables" (Printing and the Mind of Man, #179).

"Jakob Bernoulli’s pioneering work Ars Conjectandi (published posthumously, 1713; “The Art of Conjecturing”) contained many of his finest concepts: his theory of permutations and combinations; the so-called Bernoulli numbers, by which he derived the exponential series; his treatment of mathematical and moral predictability; and the subject of probability—containing what is now called the Bernoulli law of large numbers, basic to all modern sampling theory" (Britannica).

Complete with two folding tables and one folding diagram. Beautifully printed with woodcut initials and woodcut diagrams in text.
