The author traces the Big Bang through the rise of civilization, documenting his work with a host of the world's most advanced scientists and mathematicians to explain why things are the way they are.

"Imagine being forced to move to a new planet where YOU are the alien! The first time I heard about Planet Choom, we'd been on Mars for almost a year. But life on the Mars station was grim, and since Earth was no longer an option (we may have blown it up), it was time to find a new home. That's how we ended up on Choom with the Zhuri. They're very smart. They also look like giant mosquitos. But that's not why it's so hard to live here. There's a lot...

"Over the past century humankind has managed to do the impossible and rein in famine, plague, and war. This may seem hard to accept, but, as Harari explains in his trademark style--thorough, yet riveting--famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old...

"The Pulitzer Prize-winning author of The Sixth Extinction returns to humanity's transformative impact on the environment, now asking: After doing so much damage, can we change nature, this time to save it? That man should have dominion "over all the earth, and over every creeping thing that creepeth upon the earth" is a prophecy that has hardened into fact. So pervasive are human impacts on the planet that it's said we live in a new geological epoch:...

Susan Simmons discovers that her teacher is an alien when she sees him peel off his face after class. Susan teams up with Peter, the smartest kid in their class, to halt the alien's plans to abduct the students at the school.

It's a belief that unites the left and right, psychologists and philosophers, writers and historians. It drives the headlines that surround us and the laws that touch our lives. From Machiavelli to Hobbes, Freud to Dawkins, the roots of this belief have sunk deep into Western thought. Human beings, we're taught, are by nature selfish and governed by self-interest. Humankind makes a new argument: that it is realistic, as well as revolutionary, to assume...

"It is worse, much worse, than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible. In California, wildfires now rage year-round, destroying thousands of homes. Across the US, "500-year" storms pummel communities month after month, and floods displace tens of millions annually. This is only a preview of the changes to come. And they are coming fast....

"Biologist Rob Dun grew up listening to stories of the Mississippi River, how it flooded his grandfather's town of Greenville, swallowing up the townsfolk and leaving behind a muddy wasteland. Years later, Dunn discovered the cause of the great deluge. The Army Corps of Engineers had tried to straighten the river, cutting off its meandering oxbows in order to allow for the easy passage of boats. They had tried to bend nature to their own design. But...

Have you ever wondered why we stop to watch the orange glow that arrives before sunset, or why we flock to see cherry blossoms bloom in spring? Is there a reason that people -- regardless of gender, age, culture, or ethnicity -- are mesmerized by baby animals, and can't help but smile when they see a burst of confetti or a cluster of colorful balloons? We are often made to feel that the physical world has little or no impact on our inner joy. Increasingly,...
