A physicist speeds across space, time, and everything in between showing that our elegant universe from the Higgs boson to antimatter to the most massive group of galaxies is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come. Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings? No one but Dave Goldberg, the coolest nerd physicist on the planet, could give a hyper-drive tour of the universe like this one.

This groundbreaking book provides the first systematic comparison of America's modern wars and why they were won or lost. John D. Caldwell uses the World War II victory as the historical benchmark for evaluating the success and failure of later conflicts.

More people know who Khloe Kardashian is than who Rene Descartes was. Most can't find Delaware on a map, correctly spell the word occurrence, or name the largest ocean on the planet. But how important is it to fill our heads with facts? A few keystrokes can summon almost any information in seconds. Why should we bother learning facts at all? Best-selling author William Poundstone confronts that timely question in Head in the Cloud.

Increasingly, political parties have adopted not only different policies, but different sets of facts. As E. J. Fagan argues, partisan think tanks have helped create these alternate realities in their capacity as de facto formal party organizations. Through the analyses generated by aligned think tanks, political elites on both the left and right frequently offer radically different assessments of a policy's consequences.

Iran and the United States have been at odds for forty years, locked in a cold war that has run the gamut. In Republics of Myth, Hussein Banai, Malcolm Byrne, and John Tirman argue that a major contributing factor to this tenacious enmity is how each nation views itself.

In You Are What You Read, DiYanni provides a practical guide that shows how we can increase the benefits and pleasures of reading literature by becoming more skillful and engaged readers.

In the new essays collected here, an interdisciplinary group of scholars asks age-old questions about the nature and well-being of humans in the context of a revolutionary new biotechnology - one that has the potential to change the genetic make-up of both existing people and future generations. Welcoming listeners who study related issues and those not yet familiar with the formal study of bioethics, the authors of these essays open up a conversation about the ethics of gene editing.

The Hiddenness of God addresses the problem of divine hiddenness which concerns the ambiguity of evidence for God's existence, the elusiveness of God's comforting presence, the palpable and devastating experience of divine absence and abandonment, and more; phenomena which are hard to reconcile with the idea, central to the Jewish and Christian scriptures, that there exists a God who is deeply and lovingly concerned with the lives of humans. Michael C. Rea argues that divine hiddenness is not a problem to be explained away but rather a consequence of the nature of God himself.

The marvelous complexity of the universe emerges from several deep laws and a handful of fundamental constants that fix its shape, scale, and destiny. Where did these laws and these constants come from? And why are the laws so fruitful when written in the language of mathematics? Author Peter Atkins considers the minimum effort needed to equip the universe with its laws and its constants. He explores the origin of the conservation of energy, of electromagnetism, of classical and quantum mechanics, and of thermodynamics, showing how all these laws spring from deep symmetries.

Employers are increasingly recruiting their workers into politics to change elections and public policy - sometimes in coercive ways. Using a diverse array of evidence, including national surveys of workers and employers, as well as in-depth interviews with top corporate managers, Alexander Hertel-Fernandez's Politics at Work explains why mobilization of workers has become an appealing corporate political strategy in recent decades.

Employees are your company's most important asset. Attracting the best, getting them to do their best work, and keeping them in the organization are critical to your company's success. 1,001 Ways to Engage Employees gives you all the powerful tools you need.

Getting your employees to do their best work has never been easy. But it is a particular challenge for knowledge workers, who must attend to many different tasks and whose to-do list is often ambiguous, requiring outside-the-box thinking. Lists of dos and don'ts are rarely effective. Instead, your best bet is to align their interests with your own - the heart of motivation - and set them free to use their own drive and creativity on their, and your, behalf.
