  Why do compass needles point north—but not quite north? What guides the migration of birds, whales, and fish across the world's oceans? How is Earth able to sustain life under an onslaught of solar wind and cosmic radiation? For centuries, the world's great scientists have grappled with these questions, all rooted in the same phenomenon: Earth's magnetism.Over two thousand years after the invention of the compass, Einstein called the source of Earth's magnetic field one of greatest unsolved mysteries of physics. Here, for the first time, is the complete history of the quest to understand the planet's attractive pull—from the ancient Greeks' fascination with lodestone to the geological discovery that the North Pole has not always been in the North—and to the astonishing modern conclusions that finally revealed the true source.Skillfully told, North Pole, South Pole unfolds the human story behind the science: that of the inquisitive, persevering, and often dissenting thinkers who unlocked the secrets at our planet's core.

  Infants have a lot to make sense of in the world: Why does the sun shine and night fall; why do some objects move in response to words, while others won’t budge; who is it that looks over them and cares for them? How the developing brain grapples with these and other questions leads children, across cultures, to naturally develop a belief in a divine power of remarkably consistent traits––a god that is a powerful creator, knowing, immortal, and good—explains noted developmental psychologist and anthropologist Justin L. Barrett in this enlightening and provocative book. In short, we are all born believers. Belief begins in the brain. Under the sway of powerful internal and external influences, children understand their environments by imagining at least one creative and intelligent agent, a grand creator and controller that brings order and purpose to the world. Further, these beliefs in unseen super beings help organize children’s intuitions about morality and surprising life events, making life meaningful. Summarizing scientific experiments conducted with children across the globe, Professor Barrett illustrates the ways human beings have come to develop complex belief systems about God’s omniscience, the afterlife, and the immortality of deities. He shows how the science of childhood religiosity reveals, across humanity, a “natural religion,” the organization of those beliefs that humans gravitate to organically, and how it underlies all of the world’s major religions, uniting them under one common source. For believers and nonbelievers alike, Barrett offers a compelling argument for the human instinct for religion, as he guides all parents in how to effectively encourage children in developing a healthy constellation of beliefs about the world around them.

  Ever since he was young, Levison Wood has been fascinated by elephants and their fight for survival. Whilst trekking the Nile he saw these beasts up close, and in The Last Giants, he finally satisfies his desire to learn more about the majestic African elephant. These giants trek through some of Africa's most magnificent landscapes as they go in search of life-giving waters and pastures. El Nino's droughts and an insatiable ivory trade have cut African elephant numbers by a third in the last decade. If elephants disappear entirely, Africa's entire ecosystem could collapse. But Botswana has become a safe haven, where one-sixth of the world's elephants now reside. Each year their numbers grow and an incredible migration takes place, which Levison has now witnessed and recorded.  In The Last Giants, he teams up with local trackers to gain insight into how this iconic species survives, camps out in the wild, meets the people and tribes living on the migration's path, and joins the park rangers whose job it is to protect these land goliaths.
