Medicine in the early 1800s was a brutal business. Operations were performed without anaesthesia while conventional treatment relied on leeches, cupping and toxic potions. It was said of one surgeon, 'His surgical acquirements were very small, his operations generally very badly performed and accompanied with much bungling, if not worse.' It was lucky, for the doctor at least, that his deafness made him immune to his patients' dying groans. Into this milieu came John Elliotson, the dazzling new hope of the medical world.

Over the past few years, devastating tsunamis off the coast of the Indian Ocean have killed hundreds of thousands of people. Even more alarmingly, scientists predict that these tsunamis, as well as a series of earthquakes and volcanic eruptions, will be striking with even greater frequency and may eventually threaten Hawaii, California, and Oregon.

When neuroscientist Susan Barry was 50 years old, she took an unforgettable trip to Manhattan. As she emerged from the dim light of the subway into the sunshine, she saw a view of the city that she had witnessed many times in the past but now saw in an astonishingly new way. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space.

For a long time, scientists have wondered how life has emerged from inanimate chemistry, and whether Earth is the only place where it exists. Charles Darwin speculated about life on Earth beginning in a warm little pond. Some of his contemporaries believed that life existed on Mars. It once seemed inevitable that the truth would be known by now. It is not. For more than a century, the origins and extent of life have remained shrouded in mystery. But, as Mario Livio and Jack Szostak reveal in Is Earth Exceptional?, the veil is finally lifting.

This podcast series discusses Theosophy, which is often defined as the synthesis of science, religion and philosophy. Founded by Helena P. Blavatsky, who notably authored The Secret Doctrine and Isis Unveiled, Theosophy's scope is almost as astounding as the study's profound insights and wisdom. One small subject at a time, readings of Blavatsky and William Q. Judge are heard. One's own contemplation of the individual subjects presented, is bound to inform more than simply the moment.

Among the estimated 100 billion solar systems in the known universe, evolving life is surely abundant. That evolution is a process of "becoming" in each case. Since Newton, we have turned to physics to assess reality. But physics alone cannot tell us where we came from, how we arrived, and why our world has evolved past the point of unicellular organisms to an extremely complex biosphere.

David J. Helfand reconstructs the history of the universe—back to its first microsecond 13.8 billion years ago—with the help of atoms. He shows how, by using detectors and reactors, microscopes and telescopes, we can decode the tales these infinitesimal particles tell.

The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

Two University of Toronto students in the math and physics program discuss interesting topics in the field.

Flash crashes. Speed dating. Instant messaging. From the devices we carry to the lives we lead, everything is getting faster, faster. But where did this great acceleration come from? And where will it lead? In this vitally important new audiobook, Robert Colvile explains how the cult of disruption in Silicon Valley, the ceaseless advance of technology and our own fundamental appetite for novelty and convenience have combined to speed up every aspect of daily life.

Ka-boom! probes extremes of size and speed, depth and density, and reveals the stickiest, sweetest, smelliest and nastiest substances known to science. In an unabashed celebration of the exceptional, David Darling takes an enlightening journey through the universe's weirdest and most wonderful extremes.

This is a journey into the mysterious and transformative world where science and spirituality converge to illuminate the profound nature of love. In this book, we explore how the same forces that bind atoms and particles can also explain the magnetic pull of soulmates, the deep connection that transcends time and space, and the inexplicable resonance we feel with certain people.

In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has been clouded by myth and skepticism.

From adrenaline to dopamine, most of us are familiar with the chemicals that control us. They are the hormones and neurotransmitters that our brains run on, and Overloaded looks at the role they play in every aspect of our lives, from what we remember, how we make decisions and who we love to basic survival drives such as hunger, fear and sleep.

Beginning with a detailed discussion of the role of mathematics and experimentation in validating generalizations in physics-looking closely at the reasoning of scientists such as Galileo, Kepler, Newton, Lavoisier, and Maxwell-Harriman skillfully argues that the inductive method used in philosophy is in principle indistinguishable from the method used in physics.

Science may be known for banishing the demons of superstition from the modern world. Yet just as the demon-haunted world was being exorcized by the enlightening power of reason, a new kind of demon mischievously materialized in the scientific imagination itself. Scientists began to employ hypothetical beings to perform certain roles in thought experiments―experiments that can only be done in the imagination―and these impish assistants helped scientists achieve major breakthroughs that pushed forward the frontiers of science and technology.

Women physicists and astronomers from around the world have transformed science and society, but the critical roles they played in their fields are not always well-sung. Her Space, Her Time, authored by award-winning quantum physicist Shohini Ghose, brings together the stories of these remarkable women to celebrate their indelible scientific contributions. Her Space, Her Time is a story of innovation, leadership, and overcoming invisibility that will leave a lasting impression on any listener curious about the rule-breakers and trendsetters who illuminated our understanding of the universe.

Are we alone in the universe? It's a fundamental question for Earth-dwelling humankind. Are there other worlds like ours, out there somewhere? In Hidden in the Heavens, Jason Steffen, a former scientist on NASA's Kepler mission, describes how that mission searched for planets orbiting Sun-like stars—especially Earth-like planets circulating in Earth-like orbits.

What is the universe made of? How do we know? And what don't we know yet? Over the last 60 years, scientists around the world have worked together to explore the fundamental constituents of matter and the forces that govern their behaviour. The result so far is the Standard Model of elementary particles: a theoretical map of the basic building blocks of the universe. A Map of the Invisible is an explorer's guide to the Standard Model and the extraordinary world of particle physics.

Could there be a civilisation on a mote of dust? How much of your fate have you made? Who cleans the universe? Through more than 50 Koans - pleasingly paradoxical vignettes following the ancient Zen tradition - leading physicist Anthony Aguirre takes the listener across the world from Japan to Italy, and through ideas spanning the age, breadth and depth of the Universe. Using these beguiling Koans and a flair for explaining complex science, Aguirre covers cosmic questions that scientific giants from Aristotle to Galileo to Heisenberg have grappled with.
