When the fuzzy indeterminacy of quantum mechanics overthrew the orderly world of Isaac Newton, Albert Einstein and Erwin Schrödinger were at the forefront of the revolution. Neither man was ever satisfied with the standard interpretation of quantum mechanics, however, and both rebelled against what they considered the most preposterous aspect of quantum mechanics: its randomness. Einstein famously quipped that God does not play dice with the universe, and Schrödinger constructed his famous fable of a cat that was neither alive nor dead not to explain quantum mechanics but to highlight the apparent absurdity of a theory gone wrong. But these two giants did more than just criticize: they fought back, seeking a Theory of Everything that would make the universe seem sensible again.In Einstein's Dice and Schrödinger's Cat , physicist Paul Halpern tells the little-known story of how Einstein and Schrödinger searched, first as collabourators and then as competitors, for a theory that transcended quantum weirdness. This story of their quest,which ultimately failed,provides readers with new insights into the history of physics and the lives and work of two scientists whose obsessions drove its progress.Today, much of modern physics remains focused on the search for a Theory of Everything. As Halpern explains, the recent discovery of the Higgs Boson makes the Standard Model,the closest thing we have to a unified theory, nearly complete. And while Einstein and Schrödinger failed in their attempt to explain everything in the cosmos through pure geometry, the development of string theory has, in its own quantum way, brought this idea back into vogue. As in so many things, even when they were wrong, Einstein and Schrödinger couldn't help but get a great deal right.

Inspired by the end of the millennium, celebrated science writer Paul Halpern tackles the fate of human civilization and our planet in this meditation on the end of the world. Beginning with the religious origins of the idea of apocalypse, Halpern shows how science has borrowed the metaphor to describe potential worldwide catastrophes. He spins out various scenarios for destruction, from nuclear war and global warming to a great flood and a new Ice Age. He argues that while human history will someday come to a close-even if we survived for billions of years, we would eventually face the end of the universe itself-in the meantime we have gained extraordinary control over our fate as a species. Faced with the power to steer our planet toward paradise or transform it into hell, he says, we must take steps to avoid those catalysts of apocalypse that are within our control.

Following the end of the First World War the Mediterranean Fleet found itself heavily involved in the Eastern Mediterranean, the Sea of Marmora, the Black Sea and to a lesser extent, the Adriatic. Naval commanders were faced with complex problems in a situation of neither war nor peace. The collapse of the Ottoman, Russian and Habsburg empires created a vacuum of power in which different factions struggled for control or influence. In the Black Sea this involved the Royal Navy in intervention in 1919 and 1920 on the side of those Russians fighting the Bolsheviks. By 1920 the Allies were also faced with the challenge of the Turkish nationalists, culminating in the Chanak crisis of 1922. The 1923 Treaty of Lausanne enabled the Mediterranean Fleet finally to return to a peacetime routine, although there was renewed threat of war over Mosul in 1925-1926. These events are the subject of the majority of the documents contained in this volume. Those that comprise the final section of the book show the Mediterranean Fleet back to preparation for a major war, applying the lessons of World War One and studying how to make use of new weapons, aircraft carriers and aircraft.

As global markets toppled during the 2008 financial crisis, the Canadian market for non-bank asset-backed commercial paper (ABCP) seemed on the verge of collapsing. Fueled by a top rating from DBRS, ABCP had found its way into the portfolios of some of Canada’s most sophisticated investors as well as vulnerable retail investors who didn’t know what they were holding.The failure of the $32 billion market could have tipped Canadian and foreign credit default swap markets into chaos if it weren’t for the swift actions of a few powerful asset holders. Collectively, through the Montreal Accord and led by veteran Canadian lawyer Purdy Crawford, they managed to hold the Canadian ABCP market back from the brink of collapse by crafting a complex and innovative solution.Back from the Brink goes behind the scenes of the ABCP crisis to examine how a solution was reached and lessons learned that could prevent or mitigate future crises. The authors also examine the imaginative use of the Companies' Creditors Arrangement Act and describe the roles played by the banks, the major investors, rating agencies, and the financial regulators in the crisis’s origins and conclusions. Back from the Brink holds important lessons for anyone interested in Canadian law, the future of complex investments, and Canada’s capital markets.

The long history of one of physics' most enticing ideas: that the universe we know isn't the only one? Our books, our movies-our imaginations-are obsessed with extra dimensions, alternate timelines, and the sense that all we see might not be all there is. In short, we can't stop thinking about the multiverse. As it turns out, physicists are similarly captivated. In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics "choose" the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse. Drawing on centuries of disputation and deep vision, from luminaries like Nietzsche, Einstein, and the creators of the Marvel Cinematic Universe, Halpern reveals the multiplicity of multiverses that scientists have imagined to make sense of our reality. Whether we live in one of many different possible universes, or simply the only one there is, might never be certain. But Halpern shows one thing for sure: how stimulating it can be to try to find out.

The little-known story of how two of history's greatest physicists waged a war over the existence of the atom and the nature of reality itselfNearly 2,500 years ago, the Greek philosopher Democritus argued presciently, but without evidence, that all matter is made of tiny indivisible entities called atoms. Other sages, similarly lacking proof, suggested that nature is continuous. By the later nineteenth century, though science progressed, the question of nature's basic ingredients remained elusive. Two extraordinarily brilliant, incredibly stubborn Austrian physicists of that era-Ernst Mach and Ludwig Boltzmann-fought to determine whether flowing energy or discrete matter was the chief component of the universe. Mach treated atoms as useful fictions. Boltzmann, however, insisted atoms were a physical necessity. The titanic struggle rattled Boltzmann's nerves, and he eventually descended into madness and suicide. Extraordinary experiments soon thereafter vindicated his lonely plea for atoms. Despite their differences, both thinkers influenced the young Albert Einstein, paving the way for relativity and quantum theory. Mach is best known today for his groundbreaking work on supersonic speed and shock waves. By connecting the clash of Boltzmann and Mach to today's debates over what is fundamental, The Great Atom Debate does more than help us understand physics' past. It helps us make sense of the unseen entities that loom over physics' future.

In Fall 1939, Richard Feynman, a brash and brilliant recent graduate of MIT, arrived in John Wheeler's Princeton office to report for duty as his teaching assistant. The prim and proper Wheeler timed their interaction with a watch placed on the table. Feynman caught on, and for the next meeting brought his own cheap watch, set it on the table next to Wheeler's, and also began timing the chat. The two had a hearty laugh and a lifelong friendship was born.At first glance, they would seem an unlikely pair. Feynman was rough on the exterior, spoke in a working class Queens accent, and loved playing bongo drums, picking up hitchhikers, and exploring out-of-the way places. Wheeler was a family man, spoke softly and politely, dressed in suits, and had the manners of a minister. Yet intellectually, their roles were reversed. Wheeler was a raging nonconformist, full of wild ideas about space, time, and the universe. Feynman was very cautious in his research, wanting to prove and confirm everything himself. Yet when Feynman saw merit in one of Wheeler's crazy ideas and found that it matched experimental data, their joint efforts paid off phenomenally.The brilliance and originality of each physicist stimulated the other's imagination, leading to a rethinking of the nature of time and reality that proved essential for late-20th century breakthroughs in particle physics. Instead of a linear flow, Feynman's concept of "sum over histories" showed how the path a particle takes is a blend of all possible options that a particle could follow. Wheeler's attempts to remake particle physics from the ground up, spurred the now landmark idea of wormholes, and influenced his student Hugh Everett's conception of the Many Worlds Interpretation of quantum mechanics. The two thinkers pioneered the use of doodles and diagrams in explaining quantum interactions, giving birth to the now essential Feynman diagrams that show possible backward- and forward-in-time paths for particles. And this is only the tip of the iceberg.As The Quantum Labyrinth reveals in a riveting read, together, Feynman and Wheeler made sure that quantum physics would never be the same again.

In the past decade, Paul Halpern has brought readers three stunning histories of science -- Einstein's Dice and Schroedinger's Cats, The Quantum Labyrinth, and Synchronicity -- that reveal the twisted, bizarre, and illuminating stories of physics' greatest thinkers and ideas. In Flashes of Creation, Halpern turns to what might be the biggest story of them all: the discovery of the origins of the universe and everything in it.Today, the Big Bang is so deeply entrenched in our understanding of the universe that to doubt it would seem crazy. And that is pretty much what has happened to the last major opponent of the theory, British astronomer Fred Hoyle. If anyone knows his name today, they probably think he went off the deep end-or at least was so very wrong for so long as to seem completely obtuse. But the hot-headed Hoyle saw himself as a crusader for physics, defending scientific progress from a band of charlatans. His doggedness was equalled by one man alone: Russian-American physicist George Gamow, who saw the idea of the Big Bang as essential to explaining where the Universe came from, and why it's full of the matter that surrounds us. The stakes were high! And the ensuing battle, waged in person and through the media over decades, was as fiery as the cosmic cataclysm the theory describes.Most of us might guess who turned out to be right (Gamow, mostly) and who noisily spun out of control as the evidence against his position mounted (Hoyle). Unfortunately for Hoyle, he is mostly remembered for giving the theory the silliest name he could think of: "The Big Bang." But as Halpern so eloquently demonstrates, even the greatest losers in physics -- including those who seem as foolish and ornery as Fred Hoyle -- have much to teach us, about boldness, imagination, and even the universe itself.

In Synchronicity Paul Halpern tells the little-known story of the unlikely friendship between the Nobel-prize-winning quantum physicist Wolfgang Pauli and the father of psychoanalysis, Carl Jung. In the 1930s, Pauli and Jung began collaborating on a unified theory of quantum and the mind, the result of which was Jung's synchronicity principle-the idea that events connected by meaning need not be explained by causality. Pauli's work on entanglement theory, which allowed for instantaneous cause and effect relationships, was particularly appealing to Jung, as it seemed to give weight to his controversial theory of a collective unconscious.Casting their relationship within a larger intellectual history of entanglement theory, Halpern poses a question that has mystified physicists and philosophers alike since the times of Aristotle: Is the speed of light finite, as Einstein posited, or is it, as Pauli and the proponents of entanglement theory asserted, variable across time and dimensions? As Halpern works his way through the history of the physics of cause and effect, he shows that this centuries-old debate is not only relevant at the smallest scales of particle physics but also at the largest scales of the cosmos itself.
