• Abstract: This book is a philosopher's introduction to the idea that our universe is just one of many universes. I present and assess three versions of the idea: one version from philosophy, and two from physics. In short, they are: all the logically possible worlds; all the branches of the quantum state, in an Everettian interpretation of quantum theory; and all the bubbles of inflationary cosmology. For each proposal, I choose one main philosophical question to discuss in depth. They are, respectively: what is a possible world; what is chance; and what is explanation. But before treating these proposals and their associated questions, I set the stage by reviewing physics and philosophy from about 1600 to about 1900; and a final Chapter compares and contrasts the proposals.

• Laws of Physics [0.0]
  Despite its apparent complexity, our world seems to be governed by simple laws of physics. I suggest that laws are fundamental facts that govern the world by constraining its physical possibilities. I examine three hallmarks of laws--simplicity, exactness, and objectivity--and discuss whether and how they may be associated with laws of physics.

  Healey proposes a new interpretation of quantum theory inspired by pragmatist philosophy. The central idea of Healey's proposal is to understand quantum theory as providing not a description of the physical world but a set of authoritative and objectively correct prescriptions about how agents should act.

For our universe, this mechanism may only require there to be around a dozen currently unknown fundamental constants.

• The Philosophy of Quantum Computing [0.0]
  From the philosopher's perspective, the interest in quantum computation stems primarily from the way that it combines fundamental concepts from two distinct sciences. Quantum computing combines both of these more traditional areas of inquiry into one wholly new (if not quite independent) science. There are philosophical questions that arise from this merger, and philosophical lessons to be learned.

  The study of the early era of the universe involves the ideal terrain to analyze the interface between General Relativity and Quantum physics. It is also an area in which we have a large number of observational data to test our theoretical ideas. This article will orbit around these ideas and summarizes how it is that today, from recent works, we are in a position to try to challenge them.
