Sean Carroll is creating a profoundly new approach to sharing physics with a broad audience, one that goes beyond analogies to show how physicists really think. He cuts to the bare mathematical essence of our most profound theories, explaining every step in a uniquely accessible way. Quantum field theory is how modern physics describes nature at its most profound level. Starting with the basics of quantum mechanics itself, Sean Carroll explains measurement and entanglement before explaining how ...

As a Hillary voter, a New York Times reporter, and frequent attendee at her local gay bars, Nellie Bowles fit right in with her San Francisco neighbors and friends—until she started questioning whether the progressive movement she knew and loved was actually helping people. When her colleagues suggested that asking such questions meant she was "on the wrong side of history," Bowles did what any reporter worth her salt would do: she started investigating for herself. The answers she found were st...

In Then I Am Myself the World , Christof Koch explores the only thing we directly experience: consciousness. At the book's heart is integrated-information theory, the idea that the essence of consciousness is the ability to exert causal power over itself, to be an agent of change. Koch investigates the physical origins of consciousness in the brain and how this knowledge can be used to measure consciousness in natural and artificial systems. Enabled by such tools, Koch reveals when and where con...

At its simplest, Bayes's theorem describes the probability of an event, based on prior knowledge of conditions that might be related to the event. But in Everything Is Predictable , Tom Chivers lays out how it affects every aspect of our lives. He explains why highly accurate screening tests can lead to false positives and how a failure to account for it in court has put innocent people in jail. A cornerstone of rational thought, many argue that Bayes's theorem is a description of almost everyth...

For thousands of years, humans have wondered whether we're alone in the cosmos. Now, for the first time, we have the technology to investigate. But once you look for life elsewhere, you realize it is not so simple. How do you find it over cosmic distances? What actually is life? As founding director of Cornell University's Carl Sagan Institute, astrophysicist Lisa Kaltenegger has built a team of tenacious scientists from many disciplines to create a specialized toolkit to find life on faraway wo...

Robin Reames breaks down the major techniques of rhetoric, pulling back the curtain on how politicians, journalists, and "journalists" convince us to believe what we believe—and to talk, vote, and act accordingly. Understanding these techniques helps us avoid being manipulated by authority figures who don't have our best interests at heart. It also grants us rare insight into the values that shape our own beliefs. Reames and Shermer discuss: rhetoric vs. facts (rhetorical truths vs. empirical tr...

We push ourselves toward the highest-paying, most prestigious jobs, seeking promotions and public recognition. As Adam Gopnik points out, the result is not so much a rat race as a rat maze, with no way out. Except one: to choose accomplishment over achievement. Achievement is the completion of the task imposed from outside. Accomplishment , by contrast, is the end point of an engulfing activity one engages in for its own sake. Shermer and Gopnik discuss: mastering the secrets of stage magic (Gop...

When Robert Zubrin published his classic book The Case for Mars a quarter century ago, setting foot on the Red Planet seemed a fantasy. Today, manned exploration is certain, and as Zubrin affirms in The New World on Mars, so too is colonization. From the astronautical engineer venerated by NASA and today's space entrepreneurs, here is what we will achieve on Mars and how. Shermer and Zubrin discuss: why not start with the moon? • what it is like on Mars • whether Mars was ever like Earth • how m...

In virtually every way that can be measured, Gen Z's mental health is worse than that of previous generations. Youth suicide rates are climbing, antidepressant prescriptions for children are common, and the proliferation of mental health diagnoses has not helped the staggering number of kids who are lonely, lost, sad and fearful of growing up. What's gone wrong with America's youth? In Bad Therapy , bestselling investigative journalist Abigail Shrier argues that the problem isn't the kids—it's t...

The Holocaust is much discussed, much memorialized, and much portrayed. But there are major aspects of its history that have been overlooked. Spanning the entirety of the Holocaust, this sweeping history deepens our understanding. Dan Stone—Director of the Holocaust Research Institute at Royal Holloway, University of London—reveals how the idea of "industrial murder" is incomplete: many were killed where they lived in the most brutal of ways. He outlines the depth of collaboration across Europe,...

Do we live inside a simulated reality or a pocket universe embedded in a larger structure about which we know virtually nothing? Is consciousness a purely physical matter, or might it require something extra, something nonphysical? According to the philosopher Eric Schwitzgebel, it's hard to say. In The Weirdness of the World , Schwitzgebel argues that the answers to these fundamental questions lie beyond our powers of comprehension. We can be certain only that the truth—whatever it is—is weird....

Over a billion copies of the Qur'an exist – yet it remains an enigma. Its classical Arabic language resists simple translation, and its non-linear style of abstract musings defies categorization. Moreover, those who champion its sanctity and compete to claim its mantle offer widely diverging interpretations of its core message – at times with explosive results. Building on his intimate portrait of the Qur'an's prophet in Muhammad the World-Changer , Mohamad Jebara returns with a vivid profile of...

Generations have been taught that evolution implies there is no overarching purpose to our existence, that life has no fundamental meaning. We are merely the accumulation of tens of thousands of intricate molecular accidents. Some scientists take this logic one step further, suggesting that evolution is intrinsically atheistic and goes against the concept of God. With respect to our evolution, nature seems to have endowed us with competing dispositions, what Wilkinson calls the dual potential of...

Could humans unknowingly be a part of a larger superorganism—one with its own motivations and goals, one that is alive, and conscious, and has the power to shape the future of our species? This is the fascinating theory from author and futurist Byron Reese, who calls this human superorganism "Agora." In We Are Agora , Reese starts by asking the question, "What is life and how did it form?" From there, he looks at how multicellular life came about, how consciousness emerged, and how other superor...

Have you ever noticed that what is thrilling on Monday tends to become boring on Friday? Even exciting relationships, stimulating jobs, and breathtaking works of art lose their sparkle after a while. People stop noticing what is most wonderful in their own lives. They also stop noticing what is terrible. They get used to dirty air. They stay in abusive relationships. People grow to accept authoritarianism and take foolish risks. They become unconcerned by their own misconduct, blind to inequalit...

The Covid-19 response was a crucible of politics and public health—a volatile combination that produced predictably bad results. As scientific expertise became entangled with political motivations, the public-health establishment found itself mired in political encampment. It was, as Sandro Galea argues, a crisis of liberalism: a retreat from the principles of free speech, open debate, and the pursuit of knowledge through reasoned inquiry that should inform the work of public health. Across fift...

Driven largely by the political Left, this transformation has led to the wholesale grouping of individuals into oppressed and oppressor classes in both theory and practice. He warns that ...
