The first popular book to explain the dramatic theory behind the Moon's genesis. This lively science history relates one of the great recent breakthroughs in planetary astronomy-a successful theory of the birth of the Moon. Science journalist Dana Mackenzie traces the evolution of this theory, one little known outside the scientific community: a Mars-sized object collided with Earth some four billion years ago, and the remains of this colossal explosion-the...

Tells the story of how the celestial objects that make up the solar system arose from common beginnings billions of years ago, and how scientists and philosophers have sought to unravel this mystery down through the centuries, piecing together the clues that enabled them to deduce the solar system's layout, its age, and the likely way it formed.

"The acclaimed author of In Search of Schrödinger's Cat searches for life on other planetsAre we alone in the universe? Surely amidst the immensity of the cosmos there must be other intelligent life out there. Don't be so sure, says John Gribbin, one of today's best popular science writers. In this fascinating and intriguing new book, Gribbin argues that the very existence of intelligent life anywhere in the cosmos is, from an astrophysicist's point...

Atoms combine to form molecules, molecules combine to form single-celled organisms. When people come together, they build societies. Our world is nested, both physically and socially, and at each level we find innovations that were necessary for the next level. Physics has gone far in mapping the basic mechanics of the simplest things and dynamics of the overall nesting, as have biology and the social sciences for their fields. But what if anything...

In this timely, provocative, and uplifting journey, the bestselling author of Walking the Bible searches for the man at the heart of the world's three monotheistic religions -- and today's deadliest conflicts. At a moment when the world is asking, "Can the religions get along?" one figure stands out as the shared ancestor of Jews, Christians, and Muslims. One man holds the key to our deepest fears -- and our possible reconciliation. Abraham. Bruce...

The Origins of Life and the Universe is the culmination of a university science professor's search for understanding and is based on his experiences teaching the fundamental issues of physics, chemistry, and biology in the classroom. What is life? Where did it come from? How can understanding the origins of life on Earth help us understand the origins of the universe, and vice versa? These are questions that have occupied us all. This is a book, then,...

The origin of life is a hotly debated topic. The Christian Bible states that God created the heavens and the Earth, all in about seven days roughly six thousand years ago. This episode in Genesis departs markedly from scientific theories developed over the last two centuries which hold that life appeared on Earth about 3.5 billion years ago in the form of bacteria, followed by unicellular organisms half a millennia later. It is this version of genesis...

When Arnold wishes he had more information for his family tree, Ms. Frizzle revs up the Magic School Bus and the class zooms back to prehistoric times. First stop: 3.5 billion years ago! There aren't any people around to ask for directions. Luckily Ms. Frizzle has a plan, and the class is right there to watch simple cells become sponges and then fish and dinosaurs, then mammals and early primates and, eventually, modern humans. It's the longest class...

Historical biogeography -- the study of the history of species through both time and place -- first convinced Charles Darwin of evolution. This field was so important to Darwin's initial theories and line of thinking that he said as much in the very first paragraph of On the Origin of Species (1859) and later in his autobiography. His methods included collected mammalian fossils in South America clearly related to living forms, tracing the geographical...

A Dartmouth anthropologist whose team discovered two ancient human species explores how our evolution toward bipedalism rendered us dominant, innovative, more compassionate, and more susceptible to health problems.
