Taxi from Another Planet
Conversations with Drivers about Life in the Universe
Charles S. Cockell
Harvard University Press, 2022

Insightful, good-humored essays on the possibilities of alien life and the uses of space exploration, based on an astrobiologist’s everyday conversations with his fellow humans—taxi drivers, to be precise.

If you’ve ever sat in the back seat of a taxi, you know that cabbies like to talk. Sports or politics, your job or theirs, taxi drivers are fine conversationalists on just about any topic. And when the passenger is astrobiologist Charles Cockell, that topic is usually space and what, if anything, lives out there.

Inspired by conversations with drivers all over the world, Taxi from Another Planet tackles the questions that everyday people have about the cosmos and our place in it. Will we understand aliens? What if there isn’t life out in the universe? Is Mars our Plan B? And why is the government spending tax dollars on space programs anyway? Each essay in this genial collection takes questions like these as a starting point on the way to a range of insightful, even poignant, observations. Cockell delves into debates over the inevitability of life and looks to both human history and scientific knowledge to consider what first contact will be like and what we can expect from spacefaring societies. He also offers a forceful argument for the sympathies between space exploration and environmentalism.

A shrewd and entertaining foray into the most fundamental mysteries, Taxi from Another Planet brings together the wisdom of scientific experts and their fellow citizens of Earth, the better to understand how life might unfold elsewhere.

Thematic Origins of Scientific Thought
Kepler to Einstein, Revised Edition
Gerald Holton
Harvard University Press, 1988

The highly acclaimed first edition of this major work convincingly established Gerald Holton’s analysis of the ways scientific ideas evolve. His concept of “themata,” induced from case studies with special attention to the work of Einstein, has become one of the chief tools for understanding scientific progress. It is now one of the main approaches in the study of the initiation and acceptance of individual scientific insights.

Three principal consequences of this perspective extend beyond the study of the history of science itself. It provides philosophers of science with the kind of raw material on which some of the best work in their field is based. It helps intellectual historians to redefine the place of modern science in contemporary culture by identifying influences on the scientific imagination. And it prompts educators to reexamine the conventional concepts of education in science.

In this new edition, Holton has masterfully reshaped the contents and widened the coverage. Significant new material has been added, including a penetrating account of the advent of quantum physics in the United States, and a broad consideration of the integrity of science, as exemplified in the work of Niels Bohr. In addition, a revised introduction and a new postscript provide an updated perspective on the role of themata. The result of this thoroughgoing revision is an indispensable volume for scholars and students of scientific thought and intellectual history.

Theory of Neutron Star Magnetospheres
F. Curtis Michel
University of Chicago Press, 1990
An incomparable reference for astrophysicists studying pulsars and other kinds of neutron stars, Theory of Neutron Star Magnetospheres sums up two decades of astrophysical research. It provides in one volume the most important findings to date on this topic, essential to astrophysicists faced with a huge and widely scattered literature.

F. Curtis Michel, who was among the first theorists to propose a neutron star model for radio pulsars, analyzes competing models of pulsars, radio emission models, winds and jets from pulsars, pulsating X-ray sources, gamma-ray burst sources, and other neutron-star driven phenomena. Although the book places primary emphasis on theoretical essentials, it also provides a considerable introduction to the observational data and its organization. Michel emphasizes the problems and uncertainties that have arisen in the research as well as the considerable progress that has been made to date.

Theory of Nonuniform Waveguides
The cross-section method
B.Z. Katsenelenbaum
The Institution of Engineering and Technology, 1998
The cross-section method is an analytical tool used in the design of components required for low-loss, highly efficient transmission of electromagnetic waves in nonuniform waveguides. When the waveguide dimensions are large compared with the wavelength, a fully three-dimensional analysis employing modern numerical methods based on finite element, finite difference, finite integration or transmission line matrix formalisms is practically impossible and the cross-section method is the only feasible analysis technique.

Thin Safety Margin
The SEFOR Super-Prompt-Critical Transient Experiments, Ozark Mountains, Arkansas, 1970–71
Jerry Havens
Arkansas Scholarly Editions , 2021

Thin Safety Margin charts the history of SEFOR, a twenty-megawatt reactor that operated for three years in the rural Ozark Mountains of Arkansas as part of an internationally sponsored program designed to demonstrate the Doppler effect in plutonium-oxide-fueled fast reactors. Authors Jerry Havens and Collis Geren draw upon this history to assess the accidental explosion risk inherent in using fast reactors to reduce the energy industry’s carbon dioxide emissions.

If a sufficiently powerful fast-neutron explosion were to cause the containment of a reactor such as SEFOR’s to fail, the reactor’s radiotoxic plutonium fuel could vaporize and escape into the surrounding environment, resulting in a miles-wide swath of destruction. The demonstration that the Doppler effect could prevent limited runaway reactivity in the event of an accident or natural disaster proved a critical development in producing safe nuclear technology. But while SEFOR was hailed as a breakthrough in nuclear safety, Havens and Geren’s examination of the project, including the partial SCRAM that occurred in late 1970, confirms experts’ concerns regarding the limits of the Doppler effect and presents a compelling argument for caution in adopting fast reactors like SEFOR to reduce carbon emissions.

Third Thoughts
The Universe We Still Don’t Know
Steven Weinberg
Harvard University Press, 2018

“The phrase ‘public intellectual’ is much bandied about. Just a few real heavyweights in the world merit the title, and Steven Weinberg is preeminent among them.”
—Richard Dawkins


“Weinberg has a knack for capturing a complex concept in a succinct, unforgettable image… One of the smartest and most diligent scientists around.”
Nature


In this wise and wide-ranging meditation, one of the most captivating science communicators of our time challenges us to reconsider the entanglement of science and society. From the cosmological to the personal, from astronomy and quantum physics to the folly of manned spaceflight and the rewards of getting things wrong, Steven Weinberg shares his views on the workings of the universe and our aspirations and limitations. Third Thoughts aims to provoke and inform and never loses sight of the human dimension of scientific discovery.

“One of the 20th century’s greatest physicists…shares his strongly-held opinions on everything from the Higgs boson to the state of theoretical physics and the problems of science and society.”
Forbes

“This book should be read not only for its insightful and illuminating explanations of a wide range of physical phenomena but also for the opportunity it affords to follow the wanderings of a brilliant mind through topics ranging from high-energy physics and the makeup of the cosmos to poetry, and from the history and philosophy of science to the dangers of economic inequality… [A] captivating book.”
—Mario Livio, Science

Three Steps to the Universe
From the Sun to Black Holes to the Mystery of Dark Matter
David Garfinkle and Richard Garfinkle
University of Chicago Press, 2008
If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory.
 
The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. 

Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.

Tibetan Buddhism and Modern Physics
Toward a Union of Love and Knowledge
Vic Mansfield
Templeton Press, 2008

Tibetan Buddhism and Modern Physics: Toward a Union of Love and Knowledge addresses the complex issues of dialogue and collaboration between Buddhism and science, revealing connections and differences between the two. While assuming no technical background in Buddhism or physics, this book strongly responds to the Dalai Lama’s “heartfelt plea” for genuine collaboration between science and Buddhism. The Dalai Lama has written a foreword to the book and the Office of His Holiness will translate it into both Chinese and Tibetan.

In a clear and engaging way, this book shows how the principle of emptiness, the philosophic heart of Tibetan Buddhism, connects intimately to quantum nonlocality and other foundational features of quantum mechanics. Detailed connections between emptiness, modern relativity, and the nature of time are also explored. For Tibetan Buddhists, the profound interconnectedness implied by emptiness demands the practice of universal compassion. Because of the powerful connections between emptiness and modern physics, the book argues that the interconnected worldview of modern physics also encourages universal compassion. Along with these harmonies, the book explores a significant conflict between quantum mechanics and Tibetan Buddhism concerning the role of causality.
 
The book concludes with a response to the question: "How does this expedition through the heart of modern physics and Tibetan Buddhism—from quantum mechanics, relativity, and cosmology, to emptiness, compassion, and disintegratedness—apply to today's painfully polarized world?" Despite differences and questions raised, the book's central message is that there is a solid basis for uniting these worldviews. From this basis, the message of universal compassion can accompany the spread of the scientific worldview, stimulating compassionate action in the light of deep understanding—a true union of love and knowledge.
 
Tibetan Buddhism and Modern Physics will appeal to a broad audience that includes general readers and undergraduate and graduate students in science and religion courses.

Time and Chance
David Z Albert
Harvard University Press, 2000

This book is an attempt to get to the bottom of an acute and perennial tension between our best scientific pictures of the fundamental physical structure of the world and our everyday empirical experience of it. The trouble is about the direction of time. The situation (very briefly) is that it is a consequence of almost every one of those fundamental scientific pictures--and that it is at the same time radically at odds with our common sense--that whatever can happen can just as naturally happen backwards.

Albert provides an unprecedentedly clear, lively, and systematic new account--in the context of a Newtonian-Mechanical picture of the world--of the ultimate origins of the statistical regularities we see around us, of the temporal irreversibility of the Second Law of Thermodynamics, of the asymmetries in our epistemic access to the past and the future, and of our conviction that by acting now we can affect the future but not the past. Then, in the final section of the book, he generalizes the Newtonian picture to the quantum-mechanical case and (most interestingly) suggests a very deep potential connection between the problem of the direction of time and the quantum-mechanical measurement problem.

The book aims to be both an original contribution to the present scientific and philosophical understanding of these matters at the most advanced level, and something in the nature of an elementary textbook on the subject accessible to interested high-school students.

Time Travel and Warp Drives
A Scientific Guide to Shortcuts through Time and Space
Allen Everett and Thomas Roman
University of Chicago Press, 2011

To see video demonstrations of key concepts from the book, please visit this website: http://www.press.uchicago.edu/sites/timewarp/

Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy—or could it really be possible to travel through time or take shortcuts between stars?

Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space—and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible—killing your own grandfather is only one of them!

Written with a light touch and an irrepressible love of the fun of sci-fi scenarios—but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.

Time Warps, String Edits, and Macromolecules
The Theory and Practice of Sequence Comparision
David Sankoff and Joseph Kruskal
CSLI, 1983
Time Warps, String Edits and Macromolecules is a young classic in computational science. The computational perspective is that of sequence processing, in particular the problem of recognizing related sequences. The book is the first, and still best compilation of papers explaining how to measure distance between sequences, and how to compute that measure effectively. This is called string distance, Levenshtein distance, or edit distance. The book contains lucid explanations of the basic techniques; well-annotated examples of applications; mathematical analysis of its computational (algorithmic) complexity; and extensive discussion of the variants needed for weighted measures, timed sequences (songs), applications to continuous data, comparison of multiple sequences and extensions to tree-structures. This theory finds applications in molecular biology, speech recognition, analysis of bird song and error correcting in computer software.

Topics in the Foundations of General Relativity and Newtonian Gravitation Theory
David B. Malament
University of Chicago Press, 2012
In Topics in the Foundations of General Relativity and Newtonian Gravitation Theory, David B. Malament presents the basic logical-mathematical structure of general relativity and considers a number of special topics concerning the foundations of general relativity and its relation to Newtonian gravitation theory. These special topics include the geometrized formulation of Newtonian theory (also known as Newton-Cartan theory), the concept of rotation in general relativity, and Gödel spacetime. One of the highlights of the book is a no-go theorem that can be understood to show that there is no criterion of orbital rotation in general relativity that fully answers to our classical intuitions. Topics is intended for both students and researchers in mathematical physics and philosophy of science.

The Truth of Science
Physical Theories and Reality
Roger G. Newton
Harvard University Press, 1997

It's not a scientific truth that has come into question lately but the truth--the very notion of scientific truth. Bringing a reasonable voice to the culture wars that have sprung up around this notion, this book offers a clear and constructive response to those who contend, in parodies, polemics and op-ed pieces, that there really is no such thing as verifiable objective truth--without which there could be no such thing as scientific authority.

A distinguished physicist with a rare gift for making the most complicated scientific ideas comprehensible, Roger Newton gives us a guided tour of the intellectual structure of physical science. From there he conducts us through the understanding of reality engendered by modern physics, the most theoretically advanced of the sciences. With its firsthand look at models, facts, and theories, intuition and imagination, the use of analogies and metaphors, the importance of mathematics (and now, computers), and the "virtual" reality of the physics of micro-particles, The Truth of Science truly is a practicing scientist's account of the foundations, processes, and value of science.

To claims that science is a social construction, Newton answers with the working scientist's credo: "A body of assertions is true if it forms a coherent whole and works both in the external world and in our minds." The truth of science, for Newton, is nothing more or less than a relentless questioning of authority combined with a relentless striving for objectivity in the full awareness that the process never ends. With its lucid exposition of the ideals, methods, and goals of science, his book performs a great feat in service of this truth.

Tunnel Visions
The Rise and Fall of the Superconducting Super Collider
Michael Riordan, Lillian Hoddeson, and Adrienne W. Kolb
University of Chicago Press, 2015
Starting in the 1950s, US physicists dominated the search for elementary particles; aided by the association of this research with national security, they held this position for decades. In an effort to maintain their hegemony and track down the elusive Higgs boson, they convinced President Reagan and Congress to support construction of the multibillion-dollar Superconducting Super Collider project in Texas—the largest basic-science project ever attempted. But after the Cold War ended and the estimated SSC cost surpassed ten billion dollars, Congress terminated the project in October 1993.
           
Drawing on extensive archival research, contemporaneous press accounts, and over one hundred interviews with scientists, engineers, government officials, and others involved, Tunnel Visions tells the riveting story of the aborted SSC project. The authors examine the complex, interrelated causes for its demise, including problems of large-project management, continuing cost overruns, and lack of foreign contributions. In doing so, they ask whether Big Science has become too large and expensive, including whether academic scientists and their government overseers can effectively manage such an enormous undertaking.
