**R**ather (too) frequently, I get those unsolicited (hence spam) emails from Worldscientific. The latest almost sounded like a bogus book, with some sentences clearly intriguing… I recognised some names in the list of authors so it cannot be a fake, however the way it is presented is rather puzzling. (And it includes a chapter on intrinsic randomness, by Stephen Wolfram, who showed with his bewildering * New Kind of Science* how far he could be from scientific writing!) So puzzling, actually, that I may order it…

RANDOMNESS THROUGH COMPUTATION

Some Answers, More Questions

edited by Hector Zenil (Wolfram Research Inc., USA)450pp (approx.)

978-981-4327-74-9: US$90 / £56 US$67.50 / £42This review volume consists of a set of chapters written by leading scholars,

most of them founders of their fields. It explores the connections of Randomness to other areas of scientific knowledge, especially its fruitful relationship to Computability and Complexity Theory, and also to areas such as Probability, Statistics, Information Theory, Biology, Physics, Quantum Mechanics, Learning Theory and Artificial Intelligence. The contributors cover these topicswithout neglecting important philosophical dimensions, sometimes going beyond the purely technical to formulate age old questions relating to matters such as determinism and free will.The scope of Randomness Through Computation is novel. Each contributor

shares their personal views and anecdotes on the various reasons and motivations which led them to the study of Randomness. Using a question and answer format, they share their visions from their several distinctive vantage points.Contents:
