When you have magic on your side, anything is possible. At least that’s what Ephraim Scott thinks when he first discovers the unusual coin that grants his wishes. With it Ephraim overhauls his troubled home life and also his nonexistent love life. He even tries to help his friends with their problems. But every wish comes with a twist. Each flip of the coin gives Ephraim what he wants, but bad things happen too--ripples of dark consequences he doesn’t intend and can’t predict. The more Ephraim tries to fix the situation, the worse it gets. The people closest to him are changing in terrible ways and Ephraim must figure out how to harness the coin’s power before anyone gets hurt...or worse. Fair Coin is the winner of the 2012 Andre Norton Award and was a finalist for both the 2013 British Fantasy Award and the 2013 Compton Crook Award.

The sequel to the exciting adventure spun across parallel worlds! Ephraim thought his universe-hopping days were over. He's done wishing for magic solutions to his problems; his quantum coin has been powerless for almost a year, and he's settled into a normal life with his girlfriend, Jena. But then an old friend crashes their senior prom: Zoe, Jena's identical twin from a parallel world. Zoe's timing couldn't be worse. It turns out that Ephraim's problems have just begun, and they're much more complicated than his love life. The multiverse is at stake - and it might just be Ephraim's fault. Ephraim, Jena, and Zoe embark on a mission across multiple worlds to learn what's going wrong and how to stop it. They will have to draw on every resource available and trust in alternate versions of themselves and their friends before it's too late for all of them. If Ephraim and his companions can put their many differences aside and learn to work together, they might have a chance to save the multiverse. But ultimately, the solution may depend on how much they're willing to sacrifice for the sake of humanity . . . and each other. From the Hardcover edition.

The coin toss is really just a metaphor for a random event that has only two possible outcomes. The actual tossing of a real coin is just one way to realize such an event. There are many examples of questions that are equivalent to a coin toss. For example: Will the stock market close up or down tomorrow? Will a die roll come up with an even or odd number? Will we make contact with extraterrestrials within the next ten years? Will a car drive by in the next minute? Will tomorrow be sunny or cloudy? Will my medical test result be negative or positive? Will I enjoy this movie? Will the next joke be funny? Will the Earth's average temperature go up next year?Because a coin toss is equivalent to such a wide variety of questions, the results in this book are widely applicable.Because the coin toss is the simplest random event you can imagine, many questions about coin tossing can be asked and answered in great depth. The simplicity of the coin toss also opens the road to more advanced probability theories dealing with events with an infinite number of possible outcomes.This book is very mathematical. Some knowledge of calculus, discrete math, and generating functions is helpful to get the most out of it. A review of discrete math is provided in the index,

New and thoroughly updated, Epistemology: An Anthology continues to represent the most comprehensive and authoritative collection of canonical readings in the theory of knowledge. Concentrates on the central topics of the field, such as skepticism and the Pyrrhonian problematic, the definition of knowledge, and the structure of epistemic justification Offers coverage of more specific topics, such as foundationalism vs coherentism, and virtue epistemology Presents wholly new sections on 'Testimony, Memory, and Perception' and 'The Value of Knowledge' Features modified sections on 'The Structure of Knowledge and Justification', 'The Non-Epistemic in Epistemology', and 'The Nature of the Epistemic' Includes many of the most important contributions made in recent decades by several outstanding authors

In The Art of Causal Conjecture, Glenn Shafer lays out a new mathematical and philosophical foundation for probability and uses it to explain concepts of causality used in statistics, artificial intelligence, and philosophy. The various disciplines that use causal reasoning differ in the relative weight they put on security and precision of knowledge as opposed to timeliness of action. The natural and social sciences seek high levels of certainty in the identification of causes and high levels of precision in the measurement of their effects. The practical sciences -- medicine, business, engineering, and artificial intelligence -- must act on causal conjectures based on more limited knowledge. Shafer's understanding of causality contributes to both of these uses of causal reasoning. His language for causal explanation can guide statistical investigation in the natural and social sciences, and it can also be used to formulate assumptions of causal uniformity needed for decision making in the practical sciences. Causal ideas permeate the use of probability and statistics in all branches of industry, commerce, government, and science. The Art of Causal Conjecture shows that causal ideas can be equally important in theory. It does not challenge the maxim that causation cannot be proven from statistics alone, but by bringing causal ideas into the foundations of probability, it allows causal conjectures to be more clearly quantified, debated, and confronted by statistical evidence.

This work breaks new ground by carefully distinguishing the concepts of belief, confirmation, and evidence and then integrating them into a better understanding of personal and scientific epistemologies. It outlines a probabilistic framework in which subjective features of personal knowledge and objective features of public knowledge have their true place. It also discusses the bearings of some statistical theorems on both formal and traditional epistemologies while showing how some of the existing paradoxes in both can be resolved with the help of this framework.This book has two central aims: First, to make precise a distinction between the concepts of confirmation and evidence and to argue that failure to recognize this distinction is the source of certain otherwise intractable epistemological problems. The second goal is to demonstrate to philosophers the fundamental importance of statistical and probabilistic methods, at stake in the uncertain conditions in which for the most part we lead our lives, not simply to inferential practice in science, where they are now standard, but to epistemic inference in other contexts as well. Although the argument is rigorous, it is also accessible. No technical knowledge beyond the rudiments of probability theory, arithmetic, and algebra is presupposed, otherwise unfamiliar terms are always defined and a number of concrete examples are given. At the same time, fresh analyses are offered with a discussion of statistical and epistemic reasoning by philosophers. This book will also be of interest to scientists and statisticians looking for a larger view of their own inferential techniques.The book concludes with a technical appendix which introduces an evidential approach to multi-model inference as an alternative to Bayesian model averaging.
