Mapping the Heavens provides a tour of the "greatest hits" of cosmological discoveries - the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research - an astrophysicist who literally creates maps of invisible matter in the universe.

Light in the Darkness examines how mankind has always looked to the skies, mapping the journey from millennia ago when we turned our gaze to the heavens, to modern astrophysics. Heino Falcke and Jorg Romer entertainingly and compellingly chart the breakthrough research of Falcke's team, an unprecedented global community of international colleagues developing a telescope complex enough to look directly into a black hole - a hole where light vanishes, and time stops.

Long before there was VHS versus Betamax, Windows versus Macintosh, or Blu-Ray versus HD-DVD, the first and nastiest standards war was fought over how electricity would be transmitted around the world: alternating current (AC) and direct current (DC). The savage showdown between AC and DC changed the lives of billions of people, shaped the modern technological age, and set the stage for all standards wars to follow.

When his missionary brother renounced faith in favor of atheism, Perry Marshall was plunged into crisis and doubt. He decided: “I”m going to let science make this decision for me.” He asked: “Is the hand at the end of my arm purposeful? Or is it purposeless?” He leapt into the void of evolution and the origin of life. He could not have begun to anticipate what he was about to discover. Living things were far more sophisticated than textbooks were saying.

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.

A short and entertaining introduction to thermodynamics that uses real-world examples to explain accessibly an important but subtle scientific theory.    

Ernest Rutherford, who grew up in colonial New Zealand and came to Cambridge on a scholarship, made numerous revolutionary discoveries, among them the orbital structure of the atom and the concept of the “half-life” of radioactive materials, which led to a massive re-evaluation of the age of the Earth―previously judged just 100 million years old. Above all, perhaps, Rutherford and the young men working under him were the first to split the atom, unlocking tremendous forces―forces, as Rutherford himself predicted, that would bring us the atomic bomb.

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

Ambassadors from Earth relates the story of the first unmanned space probes and planetary explorers - from the Sputnik and Explorer satellites launched in the late 1950's to the thrilling interstellar Voyager missions of the '70's - that yielded some of the most celebrated successes and spectacular failures of the space age. Jay Gallentine delivers a quirky and unforgettable look at the lives and legacy of the Americans and Soviets who conceived, built, and guided those unmanned missions to the planets and beyond.

As you read this, billions of neutrinos from the sun are passing through your body, antimatter is sprouting from your dinner and the core of your being is a chaotic mess of particles known only as quarks and gluons. If the recent discovery of the Higgs boson piqued your interest, then Why the Universe Exists will take you deeper into the world of particle physics, with leading physicists and New Scientist exploring how the universe functions at the smallest scales.

This audiobook contains a broad overview of time travel in science fiction, along with a detailed examination of the philosophical implications of time travel. The emphasis of this book is now on the philosophical and on science fiction, rather than on physics, as in the author’s earlier books on the subject. In that spirit there are, for example, no tech notes filled with algebra, integrals, and differential equations, as there are in the first and second editions of Time Machines.

Ever wonder about how light moves? What does it mean to study the smallest particles known to man? How does science measure the smallest particles in the world, such as atoms, protons, neutrons and electrons? What is ether and how did it become a source of debate in the scientific community? Studying the smallest particles known to man can be exciting work. This study of the world on the molecular level, particularly matter and energy, is the realm of Quantum Physics.

In the 1970s, amid severe cutbacks in physics funding, a small group of underemployed physicists in Berkeley decided to throw off the constraints of academia and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued a freewheeling, speculative approach to physics. Some dabbled with LSD while conducting experiments. They studied quantum theory alongside Eastern mysticism and psychic mind reading, discussing the latest developments while lounging in hot tubs.

Is it possible for something or someone to be made invisible? This question, which has intrigued authors of science fiction for over a century, has become a headline-grabbing topic of scientific research. In this book, science writer and optical physicist Gregory J. Gbur traces the science of invisibility from its sci-fi origins in the nineteenth-century writings of authors such as H. G. Wells and Fitz James O'Brien to modern stealth technology, invisibility cloaks, and metamaterials. He explores the history of invisibility and its science and technology connections.

The fundamental outlines of the physical world, from its tiniest particles to massive galaxy clusters, have been apparent for decades. Does this mean physicists are about to tie it all up into a neat package? Not at all. Just when you think you’re figuring it out, the universe begins to look its strangest, and this book illustrates how answers often lead to more questions and open up new paths to insight. 

Astronomers have successfully observed a great deal of the universe’s history, from recording the afterglow of the big bang to imaging thousands of galaxies, and even to visualising an actual black hole. There’s a lot for astronomers to be smug about. But when it comes to understanding how the universe began and grew up, we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the universe.

The volumes of data we now access can give unparalleled abilities to make predictions, respond to customer demand and solve problems. But Big Brother’s shadow hovers over it. Though big data can set us free and enhance our lives, it has the potential to create an underclass and a totalitarian state. With big data ever-present, you can’t afford to ignore it. Acclaimed science writer Brian Clegg - a habitual early adopter of new technology (and the owner of the second-ever copy of Windows in the UK) - brings big data to life.

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.

Humans have long sought to comprehend the enormities of cosmic space and time. Here, best selling science writer Timothy Ferris tells the story of that quest. He interweaves the majestic themes of astronomy, physics, religion, and philosophy with fresh and lasting portraits of the men and women who created what has been called our society's most precious treasure - its conception of the universe at large.

How does the physics we know today - a highly professionalized enterprise, inextricably linked to government and industry - link back to its origins as a liberal art in Ancient Greece? What is the path that leads from the old philosophy of nature and its concern with humankind's place in the universe to modern massive international projects that hunt down fundamental particles and industrial laboratories that manufacture marvels? This audiobook introduces us to Islamic astronomers and mathematicians calculating the size of the Earth while their caliphs conquered much of it and more.
