Ferrie’s latest “Bullsh*t” title (after Quantum Bullsh*t, 2023) takes on some of the most pernicious anti-science conspiracy theories with his trademark snark, put-downs, and pop culture references. He confronts stories about the origin of life, astrology, aliens, time travel, and the end of the world, taking readers through various non-scientific beliefs and summarizing the best current understanding science gives us. It has all the ingredients his fans have come to expect. He’s mostly preaching to the choir, as it’s hard to image this will appeal to anyone who doesn’t already agree with him, and he doesn’t really offer any new information on any of these topics. Nevertheless, it’s a solid overview of the real science behind the conspiracies. Perhaps most interesting, and what gives his work real depth, is the nuance with which he treats both science and non-scientific beliefs: despite the damage conspiracy theories can do, they tap into the essential human need for storytelling, and science can too easily become another form of dogma. Both are at their best when we embrace empathy, fascination, and inherent complexity.

**STARRED REVIEW** Summerfield, neuroscientist and former researcher at Deepmind, offers one of the most balanced and realistic assessments of the current state of AI technology as well as a summary of how AI was first conceived and developed. In doing so, he spends as much time exploring linguistics and neuroscience as he does with technology. Noam Chomsky is as much a part of this as Alan Turing is. Summerfield examines the philosophies of the major players in the AI sphere and spends some time assessing the various hopes and fears people have for it. Amongst the slate of AI-focused, pop-sci books hitting the shelves recently, this one does the best job of explaining for a lay reader how AI is structured and trained. But Summerfield takes it further, comparing the ways AI functions to the workings of the human brain to show not just the potential of AI for true intelligence and creativity but also that AI is fundamentally different from human intelligence. Those differences pose the biggest challenges to the next steps of AI development. This technology contains both tremendous potential and very real danger. Summerfield tackles all this with humor, wit, and candor.

Solar geoengineering—altering the albedo of Earth to reflect more of the sun’s energy and cool down global warming—is an idea that has long floated around the periphery of climate-change-action circles. Ramge argues that it’s an idea whose time has come. It has the potential to make a significant, immediate impact and is easily reversible. It could be accomplished on a large scale with technology that’s commonplace right now. But Ramge also urges caution: it’s not a long-term solution, merely a step that can buy us time to meet necessary carbon-reduction goals. He sees a realistic danger that nonstate actors may take it upon themselves to pursue this path. There’s been very little research into solar geoengineering, so we don’t have a full understanding of the risks and possible consequences. The possibility that someone, somewhere, may turn to this approach creates an urgent need for better understanding and regulatory framework. Dimming the sun is a realistic and potentially powerful option to combat climate change. Ramge believes we should at least explore the possibility.

Santos’ second offering on the history of radioactivity (after Half Lives, 2021) takes readers through the history of uranium and its by-products. The earliest use of uranium was as a colorant for glass and ceramics, a use which continued into the twentieth century. Supposed medicinal uses spurred a rush to locate and mine uranium deposits, with devastating consequences for Native populations across the world. Most famously, uranium fueled the development of nuclear weapons and has been controversial as a power source. But nuclear power has a safety record surpassed only by solar, and radioactivity isn’t as dangerous as we once believed. Santos argues nuclear power deserves reassessment and another chance, especially in light of the urgent need to wean society off fossil fuels. Some of this content will be familiar to readers of Santos’ previous work, and the use of uranium in nuclear weapons and power is widely understood, so this book offers fewer surprises than its predecessor. Nonetheless, it is well researched and engaging and an important corrective to the misinformation and paranoia that surround uranium.

**STARRED REVIEW** It’s impossible to prevent most natural disasters. The exceptions to this are asteroid and comet strikes—stopping cosmic impacts is possible and could save literally billions of lives. Framed around an account of NASA’s recent DART mission (Double Asteroid Redirection Test), Andrews takes readers on an exciting tour of how the science of planetary defense was born and where scientists are hoping to take it from here. He interviewed several of the most prominent people involved in planetary defense, sharing their firsthand accounts of their work and motivations, which provide compelling insight into this growing field. We know how to stop asteroids and comets from hitting Earth, using everything from deflecting them with fast rockets to disintegrating them with nuclear bombs. The challenge is mostly in how we detect these threats, especially smaller “city killers,” and Andrews offers compelling arguments for the need to build a stronger detection network. Andrews’ writing style is funny, wry, passionate, and deeply informed. How to Kill an Asteroid is one of the most entertaining pop-science reads of the year.

**STARRED REVIEW** Many of us have a sense that modern technology, especially social media, is damaging human society and relationships. Smith was curious to understand if that’s true and, if so, why. Here, he takes a deep dive into the culture of computer coders: he learned to code, attended coding conferences, and interviewed some of the most eminent persons of the coding world. Along the way, he offers a course in the history of the creation and development of computers and code, a necessary context to understand how we got to where we are today. He explores the nature of coding itself: is it more math or language, science or art, and how do human brains process it? He also calls our attention to the divisive, often counterintuitive history of diversity in tech. Smith believes modern technology is doing harm to society and ultimately suggests a well-reasoned argument for why, with suggestions to address the damage. But technology also offers tremendous potential to do good, and much of the culture around tech is deep with creativity, imagination, and hope. Devil in the Stack is a humane, nuanced, humorous, insightful work and a much-needed call for greater due diligence around some of the most impactful innovations in human history.
