In 1584, while living in the household of Michel de Castelnau, the French Ambassador to the court of Queen Elizabeth of England, Giordano Bruno completed three books of cosmological dialogues: The Ash Wednesday Supper; On Cause, Principle and Unity; and the current volume, On the Infinite, the Universe and the Worlds. Drawing on the work of Lucretius, Nicholas da Cusa, Nicholas Copernicus and others, Bruno developed the theory of an infinitely extensive universe, filled with stars like our sun and planets like our own.Giordano Bruno's heretical ideas and forceful personality led to a turbulent life in which he travelled to most of the great academic and cultural centers of Europe, culminating in his trial and execution by the Roman Inquisition in 1600.Recently, this work and Giordano Bruno were referenced in the new series of Cosmos.

What happened before the primordial fire of the Big Bang: a theory about the ultimate origin of the universe. In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe: cosmic inflation, before the primordial fire of the Big Bang. Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure of the cosmos and raising unavoidable questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (elementary particles and fields), closing in a full circle at the first moment of time. With quantum uncertainty its fundamental feature, this new picture of cosmic origins introduces the possibility that the origin of the universe was of a quantum nature. Kinney considers the consequences of eternal cosmic inflation. Can we come to terms with the possibility that our entire observable universe is one of infinitely many, forever hidden from our view?

'Science has never had an advocate quite like David Deutsch ... A computational physicist on a par with his touchstones Alan Turing and Richard Feynman, and a philosopher in the line of his greatest hero, Karl Popper. His arguments are so clear that to read him is to experience the thrill of the highest level of discourse available on this planet and to understand it' Peter Forbes, Independent In our search for truth, how far have we advanced? This uniquely human quest for good explanations has driven amazing improvements in everything from scientific understanding and technology to politics, moral values and human welfare. But will progress end, either in catastrophe or completion - or will it continue infinitely? In this profound and seminal book, David Deutsch explores the furthest reaches of our current understanding, taking in the Infinity Hotel, supernovae and the nature of optimism, to instill in all of us a wonder at what we have achieved - and the fact that this is only the beginning of humanity's infinite possibility. 'This is Deutsch at his most ambitious, seeking to understand the implications of our scientific explanations of the world ... I enthusiastically recommend this rich, wide-ranging and elegantly written exposition of the unique insights of one of our most original intellectuals' Michael Berry, Times Higher Education Supplement 'Bold ... profound ... provocative and persuasive' Economist 'David Deutsch may well go down in history as one of the great scientists of our age' Scotsman

Giordano Bruno is one of the great figures of early modern Europe, and one of the least understood. Ingrid D. Rowland's pathbreaking life of Bruno establishes him once and for all as a peer of Erasmus, Shakespeare, and Galileo, a thinker whose vision of the world prefigures ours. By the time Bruno was burned at the stake as a heretic in 1600 on Rome's Campo dei Fiori, he had taught in Naples, Rome, Venice, Geneva, France, England, Germany, and the "magic Prague" of Emperor Rudolph II. His powers of memory and his provocative ideas about the infinity of the universe had attracted the attention of the pope, Queen Elizabeth—and the Inquisition, which condemned him to death in Rome as part of a yearlong jubilee. Writing with great verve and sympathy for her protagonist, Rowland traces Bruno's wanderings through a sixteenth-century Europe where every certainty of religion and philosophy had been called into question and shows him valiantly defending his ideas (and his right to maintain them) to the very end. An incisive, independent thinker just when natural philosophy was transformed into modern science, he was also a writer of sublime talent. His eloquence and his courage inspired thinkers across Europe, finding expression in the work of Shakespeare and Galileo. Giordano Bruno allows us to encounter a legendary European figure as if for the first time.
