Part of the MIT Press Essential Knowledge series
The discovery of functional MRI (fMRI) methodology in 1991 was a breakthrough in neuroscience research. This non-invasive, relatively high-speed, and high sensitivity method of mapping human brain activity enabled observation of subtle localized changes in blood flow associated with brain activity. Thousands of scientists around the world have not only embraced fMRI as a new and powerful method that complemented their ongoing studies but have also gone on to redirect their research around this revolutionary technique. This volume in the MIT Press Essential Knowledge series offers an accessible introduction to the history, fundamental concepts, challenges, and controversies of fMRI, written by one of the pioneers in the field.
Peter Bandettini covers the essentials of fMRI, providing insight and perspective from his nearly three decades of research. He describes other brain imaging and assessment methods; the sources of fMRI contrasts; the basic methodology, from hardware to pulse sequences; brain activation experiment design strategies; and data and image processing. A unique, standalone chapter addresses major controversies in the field, outlining twenty-six challenges that have helped shape fMRI research. Finally, Bandettini lays out the four essential pillars of fMRI: technology, methodology, interpretation, and applications.
Espionage
A Concise History
by Kristie Macrakis
read by Holly Adams
Part of the MIT Press Essential Knowledge series
A concise introduction to the history and methods of espionage, illustrated by spy stories from antiquity to today's high-tech world.
Espionage is one of the most secret of human activities. It is also, as the popularity of spy stories suggests, one of the most intriguing. This book pulls the veil back on the real world of espionage, revealing how spying actually works. In a refreshingly clear, concise manner, Kristie Macrakis guides listeners through the shadowy world of espionage, from the language and practice of spycraft to its role in international politics, its bureaucratic underpinnings, and its transformation in light of modern technology. Espionage is a mirror of society and human foibles with the added cloak of secrecy and deception. Accordingly, Espionage traces spying all the way back to antiquity, while also moving beyond traditional accounts of military and diplomatic intelligence to shine a light on industrial espionage and the new techno-spy. As thorough-and thoroughly enjoyable-as it is compact, the book is an ideal introduction to the history and anatomy of espionage.
AI Ethics
by Mark Coeckelbergh
read by Liam Gerrard
Part of the MIT Press Essential Knowledge series
Artificial intelligence powers Google's search engine, enables Facebook to target advertising, and allows Alexa and Siri to do their jobs. AI is also behind self-driving cars, predictive policing, and autonomous weapons that can kill without human intervention. These and other AI applications raise complex ethical issues that are the subject of ongoing debate. This volume in the MIT Press Essential Knowledge series offers an accessible synthesis of these issues.
Mark Coeckelbergh describes influential AI narratives, ranging from Frankenstein's monster to transhumanism and the technological singularity. He surveys relevant philosophical discussions: questions about the fundamental differences between humans and machines and debates over the moral status of AI. He explains the technology of AI, describing different approaches and focusing on machine learning and data science. He offers an overview of important ethical issues, including privacy concerns, responsibility and the delegation of decision making, transparency, and bias as it arises at all stages of data science processes. He also considers the future of work in an AI economy. Finally, he analyzes a range of policy proposals and discusses challenges for policymakers.
The Conscious Mind
by Zoltan Torey
read by Don Hagen
Part of the MIT Press Essential Knowledge series
How did the human mind emerge from the collection of neurons that makes up the brain? How did the brain acquire self-awareness, functional autonomy, language, and the ability to think, to understand itself and the world? In this volume in the Essential Knowledge series, Zoltan Torey offers an accessible and concise description of the evolutionary breakthrough that created the human mind. Drawing on insights from evolutionary biology, neuroscience, and linguistics, Torey reconstructs the sequence of events by which Homo erectus became Homo sapiens. He describes the augmented functioning that underpins the emergent mind -- a new ("off-line") internal response system with which the brain accesses itself and then forms a selection mechanism for mentally generated behavior options. This functional breakthrough, Torey argues, explains how the animal brain's "awareness" became self-accessible and reflective -- that is, how the human brain acquired a conscious mind. Consciousness, unlike animal awareness, is not a unitary phenomenon but a composite process. Torey's account shows how protolanguage evolved into language, how a brain subsystem for the emergent mind was built, and why these developments are opaque to introspection. We experience the brain's functional autonomy, he argues, as free will. Torey proposes that once life began, consciousness had to emerge -- because consciousness is the informational source of the brain's behavioral response. Consciousness, he argues, is not a newly acquired "quality," "cosmic principle," "circuitry arrangement," or "epiphenomenon," as others have argued, but an indispensable working component of the living system's manner of functioning.
Contraception
A Concise History
by Donna J. Drucker
read by Christa Lewis
Part of the MIT Press Essential Knowledge series
The beginning of the modern contraceptive era began in 1882, when Dr. Aletta Jacobs opened the first birth control clinic in Amsterdam. The founding of this facility, and the clinical provision of contraception that it enabled, marked the moment when physicians started to take the prevention of pregnancy seriously as a medical concern. In this volume in the MIT Press Essential Knowledge series, Donna Drucker traces the history of modern contraception, outlining the development, manufacturing, and use of contraceptive methods from the opening of Dr. Jacobs's clinic to the present. Drucker approaches the subject from the perspective of reproductive justice: the right to have a child, the right not to have a child, and the right to parent children safely and healthily.
Drucker describes contraceptive methods available before the pill, including the diaphragm and condom. She looks at the development and dissemination of the pill and its chemical descendants; describes technological developments in such non-hormonal contraceptives as the cervical cap and timing methods; and explains the concept of reproductive justice. Finally, Drucker considers the future of contraception-the adaptations of existing methods, new forms of distribution, and ongoing efforts needed to support contraceptive access worldwide.
School Choice
by David R. Garcia
read by Stephen Bel Davies
Part of the MIT Press Essential Knowledge series
The issues and arguments surrounding school choice are sometimes hijacked to make political points about government control, democratic ideals, the public good, and privatization. In this volume in the MIT Press Essential Knowledge series, David Garcia avoids partisan arguments to offer an accessible, objective, and comprehensive guide to school choice. He first outlines the different types of school choice, including home schooling, private schools, freedom-of-choice plans, magnet schools, charter schools, vouchers, and education savings accounts. Two themes emerge as particularly resonant in the American school choice debate: the long history of school desegregation, and debates over the roles and responsibilities of government. Is education a public good, for the collective benefit of society, or a private good, to benefit the individual?
Garcia describes and evaluates the major arguments supporting school choice policies: the elimination of government bureaucracies, the introduction of competition into education through market forces, the promotion of parental choice, and the casting of school choice as a civil right. He examines the research on the effects of school choice and summarizes general trends. Finally, he considers how school choice policies are likely to evolve.
Memory
by Fergus Craik
read by William Sarris
Part of the MIT Press Essential Knowledge series
A short, accessible primer on human memory, its workings, feats, and flaws, by two leading psychological researchers.
Why do we vividly recall a traumatic childhood event but forget where we left our keys five minutes ago? How can a scent take us back fifty years while a colleague's name eludes us? In this compact introduction, two leading psychological researchers describe memory-how it works and why it sometimes doesn't; how it can be tricked, trained, or improved; and what changes with time.
In a manner as engaging as it is informative, Fergus Craik and Larry Jacoby explain the strengths and weaknesses of memory. They trace evolving ideas about memory's function and present a down-to-earth account of modern views. Citing the latest research, they outline the processes for acquiring and retrieving memories and explore the distinction between conscious and unconscious processes. With insights into the workings of the brain, Craik and Jacoby also provide a succinct account of feats and failures of memory, emotion and false memories, and the effects of aging. Their book draws a clear picture, at once broad and concise, of current and classical views of memory, that most essential and often mysterious feature of human life.
Computing
A Concise History
by Paul E. Ceruzzi
read by Timothy Andrés Pabon
Part of the MIT Press Essential Knowledge series
The history of computing could be told as the story of hardware and software, or the story of the Internet, or the story of "smart" hand-held devices, with subplots involving IBM, Microsoft, Apple, Facebook, and Twitter. In this concise and accessible account of the invention and development of digital technology, computer historian Paul Ceruzzi offers a broader and more useful perspective. He identifies four major threads that run throughout all of computing's technological development: digitization--the coding of information, computation, and control in binary form, ones and zeros; the convergence of multiple streams of techniques, devices, and machines, yielding more than the sum of their parts; the steady advance of electronic technology, as characterized famously by "Moore's Law"; and the human-machine interface. Ceruzzi guides us through computing history, telling how a Bell Labs mathematician coined the word "digital" in 1942 (to describe a high-speed method of calculating used in anti-aircraft devices), and recounting the development of the punch card (for use in the 1890 U.S. Census). He describes the ENIAC, built for scientific and military applications; the UNIVAC, the first general purpose computer; and ARPANET, the Internet's precursor. Ceruzzi's account traces the world-changing evolution of the computer from a room-size ensemble of machinery to a "minicomputer" to a desktop computer to a pocket-sized smart phone. He describes the development of the silicon chip, which could store ever-increasing amounts of data and enabled ever-decreasing device size. He visits that hotbed of innovation, Silicon Valley, and brings the story up to the present with the Internet, the World Wide Web, and social networking.

Part of the MIT Press Essential Knowledge series
In December 2012, the exuberant video "Gangnam Style" became the first YouTube clip to be viewed more than one billion times. Thousands of its viewers responded by creating and posting their own variations of the video--"Mitt Romney Style," "NASA Johnson Style," "Egyptian Style," and many others. "Gangnam Style" (and its attendant parodies, imitations, and derivations) is one of the most famous examples of an Internet meme: a piece of digital content that spreads quickly around the web in various iterations and becomes a shared cultural experience. In this audiobook, Limor Shifman investigates Internet memes and what they tell us about digital culture. Shifman discusses a series of well-known Internet memes -- including "Leave Britney Alone," the pepper-spraying cop, LOLCats, Scumbag Steve, and Occupy Wall Street's "We Are the 99 Percent." She offers a novel definition of Internet memes: digital content units with common characteristics, created with awareness of each other, and circulated, imitated, and transformed via the Internet by many users. She differentiates memes from virals; analyzes what makes memes and virals successful; describes popular meme genres; discusses memes as new modes of political participation in democratic and nondemocratic regimes; and examines memes as agents of globalization. Memes, Shifman argues, encapsulate some of the most fundamental aspects of the Internet in general and of the participatory Web 2.0 culture in particular. Internet memes may be entertaining, but in this audiobook Limor Shifman makes a compelling argument for taking them seriously.
The Book
by Amaranth Borsuk
read by Sarah Mollo-Christensen
Part of the MIT Press Essential Knowledge series
In this volume in the MIT Press Essential Knowledge series, Amaranth Borsuk considers the history of the book, the future of the book, and the idea of the book. Tracing the interrelationship of form and content in the book's development, she bridges book history, book arts, and electronic literature to expand our definition of an object we thought we knew intimately. Contrary to the many reports of its death (which has been blamed at various times on newspapers, television, and e-readers), the book is alive. Despite nostalgic paeans to the codex and its printed pages, Borsuk reminds us, the term "book" commonly refers to both medium and content. And the medium has proved to be malleable. Rather than pinning our notion of the book to a single form, Borsuk argues, we should remember its long history of transformation. Considering the book as object, content, idea, and interface, she shows that the physical form of the book has always been the site of experimentation and play. Rather than creating a false dichotomy between print and digital media, we should appreciate their continuities.
The Internet of Things
by Samuel Greengard
read by Derek Shetterly
Part of the MIT Press Essential Knowledge series
We turn on the lights in our house from a desk in an office miles away. Our refrigerator alerts us to buy milk on the way home. A package of cookies on the supermarket shelf suggests that we buy it, based on past purchases. The cookies themselves are on the shelf because of a "smart" supply chain. When we get home, the thermostat has already adjusted the temperature so that it's toasty or bracing, whichever we prefer. This is the Internet of Things -- a networked world of connected devices, objects, and people. In this book, Samuel Greengard offers a guided tour through this emerging world and how it will change the way we live and work.
Greengard explains that the Internet of Things (IoT) is still in its early stages. Smart phones, cloud computing, RFID (radio-frequency identification) technology, sensors, and miniaturization are converging to make possible a new generation of embedded and immersive technology. Greengard traces the origins of the IoT from the early days of personal computers and the Internet and examines how it creates the conceptual and practical framework for a connected world. He explores the industrial Internet and machine-to-machine communication, the basis for smart manufacturing and end-to-end supply chain visibility; the growing array of smart consumer devices and services -- from Fitbit fitness wristbands to mobile apps for banking; the practical and technical challenges of building the IoT; and the risks of a connected world, including a widening digital divide and threats to privacy and security. Finally, he considers the long-term impact of the IoT on society, narrating an eye-opening "Day in the Life" of IoT connections circa 2025.
The Future
by Nick Monfort
read by Sean Pratt
Part of the MIT Press Essential Knowledge series
In this volume of the MIT Press's Essential Knowledge series, Nick Montfort argues that the future is something to be made, not predicted. Montfort offers what he considers essential knowledge about the future, as seen in the work of writers, artists, inventors, and designers (mainly in Western culture) who developed and described the core components of the futures they envisioned. Montfort's approach is not that of futurology or scenario planning; instead, he reports on the work of making the future-the thinkers who devoted themselves to writing pages in the unwritten book. Douglas Engelbart, Alan Kay, and Ted Nelson didn't predict the future of computing, for instance. They were three of the people who made it. Montfort focuses on how the development of technologies-with an emphasis on digital technologies-has been bound up with ideas about the future. Readers learn about kitchens of the future and the vision behind them; literary utopias, from Plato's Republic to Edward Bellamy's Looking Backward and Charlotte Perkins Gilman's Herland; the Futurama exhibit at the 1939 New York World's Fair; and what led up to Tim Berners-Lee's invention of the World Wide Web.
Fertility Technology
by Donna J. Drucker
read by Christa Lewis
Part of the MIT Press Essential Knowledge series
In the late 1850s, a physician in New York City used a syringe and glass tube to inject half a drop of sperm into a woman's uterus, marking the first recorded instance of artificial insemination. From that day forward, doctors and scientists have turned to technology in ever more innovative ways to facilitate conception. Fertility Technology surveys this history in all its medical, practical, and ethical complexity, and offers a look at state-of-the-art fertility technology in various social and political contexts around the world.
Donna J. Drucker's concise and engrossing account introduces the five principal types of fertility technologies used in human reproduction-artificial insemination; ovulation timing; sperm, egg, and embryo freezing; in vitro fertilization; and IVF in uterine transplants-discussing the development, manufacture, dispersion, and use of each. Geographically, it focuses on countries where innovations have emerged and countries where these technologies most profoundly affect individuals and population policies. Drucker's wide-ranging perspective reveals how these technologies, used for birth control as well as conception in many cases, have been critical in shaping the moral, practical, and political meaning of human life, kinship, and family in different nations and cultures since the mid-nineteenth century.
Collaborative Society
by Dariusz Jemielniak
read by Bruce Mann
Part of the MIT Press Essential Knowledge series
Humans are hard-wired for collaboration, and new technologies of communication act as a super-amplifier of our natural collaborative mindset. This volume in the MIT Press Essential Knowledge series examines the emergence of a new kind of social collaboration enabled by networked technologies. This new collaborative society might be characterized as a series of services and startups that enable peer-to-peer exchanges and interactions though technology. Some believe that the economic aspects of the new collaboration have the potential to make society more equitable; others see collaborative communities based on sharing as a cover for social injustice and user exploitation.
The book covers the "sharing economy," and the hijacking of the term by corporations; different models of peer production, and motivations to participate; collaborative media production and consumption, the definitions of "amateur" and "professional," and the power of memes; hactivism and social movements, including Anonymous and anti-ACTA protest; collaborative knowledge creation, including citizen science; collaborative self-tracking; and internet-mediated social relations, as seen in the use of Instagram, Snapchat, and Tinder. Finally, the book considers the future of these collaborative tendencies and the disruptions caused by fake news, bots, and other challenges.
Artificial General Intelligence
by Julian Togelius
read by Steve Marvel
Part of the MIT Press Essential Knowledge series
Artificial intelligence surrounds us. More and more of the systems and services you interact with every day are based on AI technology. Most AI is narrowly specific; that is, it can only do a single thing, in a single context. For example, your spellchecker can't do mathematics, and the world's best chess-playing program can't play Tetris. Human intelligence is different. We can solve a variety of tasks, including those we have not seen before. In Artificial General Intelligence, Julian Togelius explores technical approaches to developing more general artificial intelligence and asks what general AI would mean for human civilization.
Togelius starts by giving examples of narrow AI that have superhuman performance in some way. He then discusses what it would mean to have general intelligence, by looking at definitions from psychology, ethology, and computer science. Next, he explores the two main families of technical approaches to developing more general artificial intelligence: foundation models through self-supervised learning, and open-ended learning in virtual environments. The final chapters of the book investigate potential artificial general intelligence beyond the strictly technical aspects. The questions discussed here investigate whether such general AI would be conscious, whether it would pose a risk to humanity, and how it might alter society.
Sustainability
by Kent E. Portnoy
read by Don Hagen
Part of the MIT Press Essential Knowledge series
The word "sustainability" has been connected to everything from a certain kind of economic development to corporate promises about improved supply sourcing. But despite the apparent ubiquity of the term, the concept of sustainability has come to mean a number of specific things. In this accessible guide to the meanings of sustainability, Kent Portney describes the evolution of the idea and examines its application in a variety of contemporary contexts -- from economic growth and consumption to government policy and urban planning. Portney takes as his starting point the 1987 definition by the World Commission on Environment and Development of sustainability as economic development activity that "meets the needs of the present without compromising the ability of future generations to meet their own needs." At its heart, Portney explains, sustainability focuses on the use and depletion of natural resources. It is not the same as environmental protection or natural resource conservation; it is more about finding some sort of steady state so that the earth can support both human population and economic growth. Portney looks at political opposition to the promotion of sustainability, which usually questions the need for sustainability or calls its costs unacceptable; collective and individual consumption of material goods and resources and to what extent they must be curtailed to achieve sustainability; the role of the private sector, and the co-opting of sustainability by corporations; government policy on sustainability at the international, national, and subnational levels; and how cities could become models for sustainability action.
Metadata
by Jeffrey Pomerantz
read by Steven Menasche
Part of the MIT Press Essential Knowledge series
When "metadata" became breaking news, appearing in stories about surveillance by the National Security Agency, many members of the public encountered this once-obscure term from information science for the first time. Should people be reassured that the NSA was "only" collecting metadata about phone calls -- information about the caller, the recipient, the time, the duration, the location -- and not recordings of the conversations themselves? Or does phone call metadata reveal more than it seems? In this book, Jeffrey Pomerantz offers an accessible and concise introduction to metadata. In the era of ubiquitous computing, metadata has become infrastructural, like the electrical grid or the highway system. We interact with it or generate it every day. It is not, Pomerantz tell us, just "data about data." It is a means by which the complexity of an object is represented in a simpler form. For example, the title, the author, and the cover art are metadata about a book. When metadata does its job well, it fades into the background; everyone (except perhaps the NSA) takes it for granted. Pomerantz explains what metadata is, and why it exists. He distinguishes among different types of metadata -- descriptive, administrative, structural, preservation, and use -- and examines different users and uses of each type. He discusses the technologies that make modern metadata possible, and he speculates about metadata's future. By the end of the book, listeners will see metadata everywhere. Because, Pomerantz warns us, it's metadata's world, and we are just living in it.
Causal Inference

Part of the MIT Press Essential Knowledge series
A nontechnical guide to the basic ideas of modern causal inference, with illustrations from health, the economy, and public policy.
Which of two antiviral drugs does the most to save people infected with Ebola virus? Does a daily glass of wine prolong or shorten life? Does winning the lottery make you more or less likely to go bankrupt? How do you identify genes that cause disease? Do unions raise wages? Do some antibiotics have lethal side effects? Does the Earned Income Tax Credit help people enter the workforce?
Causal Inference provides a brief and nontechnical introduction to randomized experiments, propensity scores, natural experiments, instrumental variables, sensitivity analysis, and quasi-experimental devices. Ideas are illustrated with examples from medicine, epidemiology, economics and business, the social sciences, and public policy.
Machine Translation
by Thierry Poibeau
read by James Anderson Foster
Part of the MIT Press Essential Knowledge series
The dream of a universal translation device goes back many decades, long before Douglas Adams's fictional Babel fish provided this service in The Hitchhiker's Guide to the Galaxy. Since the advent of computers, research has focused on the design of digital machine translation tools-computer programs capable of automatically translating a text from a source language to a target language. This has become one of the most fundamental tasks of artificial intelligence. This volume in the MIT Press Essential Knowledge series offers a concise, nontechnical overview of the development of machine translation, including the different approaches, evaluation issues, and market potential. The main approaches are presented from a largely historical perspective and in an intuitive manner, allowing the reader to understand the main principles without knowing the mathematical details.
Understanding Beliefs
by Nils J. Nilsson
read by Don Hagen
Part of the MIT Press Essential Knowledge series
Our beliefs constitute a large part of our knowledge of the world. We have beliefs about objects, about culture, about the past, and about the future. We have beliefs about other people, and we believe that they have beliefs as well. We use beliefs to predict, to explain, to create, to console, to entertain. Some of our beliefs we call theories, and we are extraordinarily creative at constructing them. Theories of quantum mechanics, evolution, and relativity are examples. But so are theories about astrology, alien abduction, guardian angels, and reincarnation. All are products (with varying degrees of credibility) of fertile minds trying to find explanations for observed phenomena. In this book, Nils Nilsson examines beliefs: what they do for us, how we come to hold them, and how to evaluate them. We should evaluate our beliefs carefully, Nilsson points out, because they influence so many of our actions and decisions. Some of our beliefs are more strongly held than others, but all should be considered tentative and changeable. Nilsson shows that beliefs can be quantified by probability, and he describes networks of beliefs in which the probabilities of some beliefs affect the probabilities of others. He argues that we can evaluate our beliefs by adapting some of the practices of the scientific method and by consulting expert opinion. And he warns us about "belief traps" -- holding onto beliefs that wouldn't survive critical evaluation. The best way to escape belief traps, he writes, is to expose our beliefs to the reasoned criticism of others.
Citizenship
by Dimitry Kochenov
read by Liam Gerrard
Part of the MIT Press Essential Knowledge series
The glorification of citizenship is a given in today's world, part of a civic narrative that invokes liberation, dignity, and nationhood. In reality, explains Dimitry Kochenov, citizenship is a story of complacency, hypocrisy, and domination, flattering to citizens and demeaning for noncitizens. In this volume in the MIT Press Essential Knowledge series, Kochenov explains the state of citizenship in the modern world.
Kochenov offers a critical introduction to a subject most often regarded uncritically, describing what citizenship is, what it entails, how it came about, and how its role in the world has been changing. He examines four key elements of the concept: status, considering how and why the status of citizenship is extended, what function it serves, and who is left behind; rights, particularly the right to live and work in a state; duties, and what it means to be a "good citizen"; and politics, as enacted in the granting and enjoyment of citizenship.
Citizenship promises to apply the attractive ideas of dignity, equality, and human worth-but to strictly separated groups of individuals. Those outside the separation aren't citizens as currently understood, and they do not belong. Citizenship, Kochenov warns, is too often a legal tool that justifies violence, humiliation, and exclusion.
Quantum Entanglement
by Jed Brody
read by Jonathan Todd Ross
Part of the MIT Press Essential Knowledge series
Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying? In this volume in the MIT Press Essential Knowledge series, Jed Brody equips listeners to decide for themselves. He explains how our commonsense assumptions impose constraints-from which entangled particles break free.
Brody explores such concepts as local realism, Bell's inequality, polarization, time dilation, and special relativity. He introduces listeners to imaginary physicists Alice and Bob and their photon analyses; points out that it's easier to reject falsehood than establish the truth; and reports that some physicists explain entanglement by arguing that we live in a cross-section of a higher-dimensional reality. He also examines a variety of viewpoints held by physicists, including quantum decoherence, Niels Bohr's Copenhagen interpretation, genuine fortuitousness, and QBism.
Macroeconomics
by Felipe B. Larrain
read by Gary Tiedemann
Part of the MIT Press Essential Knowledge series
Macroeconomics takes a broad perspective on the economy of a country or region; it studies economic changes in the aggregate, collecting data on production, unemployment, inflation, consumption, investment, trade, and other aspects of national and international economic life. Policymakers depend on macroeconomists' knowledge when making decisions about such issues as taxes and the public budget, monetary and exchange rate policies, and trade policies-all of which, in turn, affect decisions made by individuals and businesses. This volume in the MIT Press Essential Knowledge series offers an introduction to the basics of macroeconomics accessible to the noneconomist.
The author, an academic economist and two-time Chilean Finance Minister, devotes a substantial part of his analysis to economic development, explaining why some countries achieve continuing economic growth while others become stagnant. He discusses the links between economic activity and employment; employment and unemployment rates; factors behind economic growth; money, inflation, and exchange rate systems; fiscal deficits; balance of payment crises; consumption and savings; investment decisions; fiscal policy; and the process of globalization and its macroeconomic implications.
Spatial Computing
by Shashi Shekhar
read by Rosemary Benson
Part of the MIT Press Essential Knowledge series
Billions of people around the globe use various applications of spatial computing daily-by using a ride-sharing app, GPS, the e911 system, social media check-ins, even Pokemon Go. Scientists and researchers use spatial computing to track diseases, map the bottom of the oceans, chart the behavior of endangered species, and create election maps in real time. Drones and driverless cars use a variety of spatial computing technologies. Spatial computing works by understanding the physical world, knowing and communicating our relation to places in that world, and navigating through those places. It has changed our lives and infrastructures profoundly, marking a significant shift in how we make our way in the world.
The book offers accessible descriptions of GPS and location-based services, including the use of Wi-Fi, Bluetooth, and RFID for position determination out of satellite range; remote sensing, which uses satellite and aerial platforms to monitor such varied phenomena as global food production, the effects of climate change, and subsurface natural resources on other planets; geographic information systems (GIS), which store, analyze, and visualize spatial data; spatial databases, which store multiple forms of spatial data; and spatial statistics and spatial data mining, used to analyze location-related data.
Critical Thinking
by Jonathan Haber
read by Joel Richards
Part of the MIT Press Essential Knowledge series
Critical thinking is regularly cited as an essential twenty-first century skill, the key to success in school and work. Given our propensity to believe fake news, draw incorrect conclusions, and make decisions based on emotion rather than reason, it might even be said that critical thinking is vital to the survival of a democratic society. But what, exactly, is critical thinking?
Haber describes the term's origins in such disciplines as philosophy, psychology, and science. He examines the components of critical thinking, including structured thinking, language skills, background knowledge, and information literacy, along with such necessary intellectual traits as intellectual humility, empathy, and open-mindedness. He discusses how research has defined critical thinking, how elements of critical thinking have been taught for centuries, and how educators can teach critical thinking skills now.
Haber argues that the most important critical thinking issue today is that not enough people are doing enough of it. Fortunately, critical thinking can be taught, practiced, and evaluated. This book offers a guide for teachers, students, and aspiring critical thinkers everywhere, including advice for educational leaders and policy makers on how to make the teaching and learning of critical thinking an educational priority and practical reality.
Neuroplasticity
by Moheb Costandi
read by Timothy Andrés Pabon
Part of the MIT Press Essential Knowledge series
Fifty years ago, neuroscientists thought that a mature brain was fixed like a fly in amber, unable to change. Today, we know that our brains and nervous systems change throughout our lifetimes. This concept of neuroplasticity has captured the imagination of a public eager for self-improvement -- and has inspired countless Internet entrepreneurs who peddle dubious "brain training" games and apps. In this book, Moheb Costandi offers a concise and engaging overview of neuroplasticity for the general listener, describing how our brains change continuously in response to our actions and experiences. Costandi discusses key experimental findings, and describes how our thinking about the brain has evolved over time. He explains how the brain changes during development, and the "synaptic pruning" that takes place before brain maturity. He shows that adult brains can grow new cells (citing, among many other studies, research showing that sexually mature male canaries learn a new song every year). He describes the kind of brain training that can bring about improvement in brain function. It's not gadgets and games that promise to "rewire your brain" but such sustained cognitive tasks as learning a musical instrument or a new language. (Costandi also notes that London cabbies increase their gray matter after rigorous training in their city's complicated streets.) He tells how brains compensate after stroke or injury; describes addiction and pain as maladaptive forms of neuroplasticity; and considers brain changes that accompany childhood, adolescence, parenthood, and aging. Each of our brains is custom-built. Neuroplasticity is at the heart of what makes us human.
Irony and Sarcasm
by Roger Kreuz
read by Joel Richards
Part of the MIT Press Essential Knowledge series
A biography of two troublesome words.
Irony and sarcasm are two of the most misused, misapplied, and misunderstood words in our conversational lexicon. In this volume in the MIT Press Essential Knowledge series, psycholinguist Roger Kreuz offers an enlightening and concise overview of the life and times of these two terms, mapping their evolution from Greek philosophy and Roman rhetoric to modern literary criticism to emojis.
Kreuz describes eight different ways that irony has been used through the centuries, proceeding from Socratic to dramatic to cosmic irony. He explains that verbal irony-irony as it is traditionally understood-refers to statements that mean something different (frequently the opposite) of what is literally intended, and defines sarcasm as a type of verbal irony. Kreuz outlines the prerequisites for irony and sarcasm (one of which is a shared frame of reference); clarifies what irony is not (coincidence, paradox, satire) and what it can be (among other things, a socially acceptable way to express hostility); recounts ways that people can signal their ironic intentions; and considers the difficulties of online irony. Finally, he wonders if, because irony refers to so many different phenomena, people may gradually stop using the word, with sarcasm taking over its verbal duties.
Smart Cities
by Germaine Halegoua
read by Wendy Tremont King
Part of the MIT Press Essential Knowledge series
Over the past ten years, urban planners, technology companies, and governments have promoted smart cities with a somewhat utopian vision of urban life made knowable and manageable through data collection and analysis. Emerging smart cities have become both crucibles and showrooms for the practical application of the Internet of Things, cloud computing, and the integration of big data into everyday life. Are smart cities optimized, sustainable, digitally networked solutions to urban problems? Or are they neoliberal, corporate-controlled, undemocratic non-places? This volume in the MIT Press Essential Knowledge series offers a concise introduction to smart cities, presenting key concepts, definitions, examples, and historical contexts, along with discussions of both the drawbacks and the benefits of this approach to urban life.
After reviewing current terminology and justifications employed by technology designers, journalists, and researchers, the book describes three models for smart city development and offers examples of each. It covers technologies and methods, including sensors, public wi-fi, big data, and smartphone apps, and discusses how developers conceive of interactions among the built environment, technological and urban infrastructures, citizens, and citizen engagement.
Extraterrestrials

Part of the MIT Press Essential Knowledge series
Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity-but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets?
This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens; the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology and exoplanet research. Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox-and finding extraterrestrials.
Cynicism

Everyone's a cynic, yet few will admit it. Today's cynics excuse themselves half-heartedly-"I hate to be a cynic, but . . ."-before making their pronouncements. Narrowly opportunistic, always on the take, contemporary cynicism has nothing positive to contribute. The Cynicism of the ancient Greeks, however, was very different. Bold and shameless, it was committed to transforming the values on which civilization depends. In this volume of the MIT Press Essential Knowledge series, Ansgar Allen charts the long history of cynicism, from the "fearless speech" of Greek Cynics in the fourth century BCE to the contemporary cynic's lack of social and political convictions.
Allen describes ancient Cynicism as an improvised philosophy and a way of life disposed to scandalize contemporaries, subjecting their cultural commitments to derision. He chronicles the subsequent "purification" of Cynicism by the Stoics; Renaissance and Enlightenment appropriations of Cynicism; and the transition from Cynicism (the philosophy) to cynicism (the modern attitude), exploring contemporary cynicism from the perspectives of its leftist, liberal, and conservative critics. Finally, he considers the possibility of a radical cynicism that admits and affirms the danger it poses to contemporary society.
Algorithms

Part of the MIT Press Essential Knowledge series
Digital technology runs on algorithms, sets of instructions that describe how to do something efficiently. Application areas range from search engines to tournament scheduling, DNA sequencing, and machine learning. Arguing that every educated person today needs to have some understanding of algorithms and what they do, in this volume in the MIT Press Essential Knowledge series, Panos Louridas offers an introduction to algorithms that is accessible to nonspecialists. Louridas explains not just what algorithms are but also how they work, offering a wide range of examples and keeping mathematics to a minimum.
After discussing what an algorithm does and how its effectiveness can be measured, Louridas covers three of the most fundamental applications areas: graphs, which describe networks, from eighteenth-century problems to today's social networks; searching, and how to find the fastest way to search; and sorting, and the importance of choosing the best algorithm for particular tasks. He then presents larger-scale applications: PageRank, Google's founding algorithm; and neural networks and deep learning. Finally, Louridas describes how all algorithms are nothing more than simple moves with pen and paper, and how from such a humble foundation rise all their spectacular achievements.
Pragmatism

Part of the MIT Press Essential Knowledge series
A concise, accessible overview of pragmatism, the most influential school of American philosophical thought.
Pragmatism, America's homegrown philosophy, has been a major intellectual movement for over a century. Unlike its rivals, it reaches well beyond the confines of philosophy into concerns and disciplines as diverse as religion, politics, science, and culture. In this concise, engagingly written overview, John R. Shook describes pragmatism's origins, concepts, and continuing global relevance and appeal. With attention to the movement's original thinkers-Charles Sanders Peirce, William James, John Dewey, and George Herbert Mead-as well as its contemporary proponents, he explains how pragmatism thinks about what is real, what can be known, and what minds are doing. And because of pragmatism's far-reaching impact, Shook shows how its views on reality, truth, knowledge, and cognition coordinate with its approaches to agency, sociality, human nature, and personhood.
Galaxies

In “Galaxies,” Or Graur offers a brief and fascinating overview of the history, physics, and astrophysical uses of galaxies. Starting with the history of the last two thousand years of galaxy studies, Graur discusses the types of galaxies we observe and the physics that drive them; the myths and physical structure of the Milky Way; how galaxies were used to discover and study the mysterious phenomena of dark matter and dark energy; and how scientists think galaxies formed shortly after the Big Bang and evolved to their present forms.
Tracing galaxy studies back thousands of years ago to their beginnings, Graur describes their origin in Ptolemy's book Almagest, which was written in the first century CE. Almagest catalogued hundreds of stars and a few hazy cloud-like objects, one of which was the Andromeda galaxy. The listener will also encounter in this book well-known figures such as William Herschel, who, along with his sister Caroline, discovered hundreds of galaxies and lay the foundations for modern galaxy studies, as well as lesser-known astronomers, including tenth-century Persian astronomer Abd al-Rahman al-Sufi. Galaxies concludes by showing listeners how they can get involved in galaxy studies themselves and do their part to fight the light pollution that today obscures the Milky Way and all but the brightest of stars.
Tech Monopoly
by Herbert Hovenkamp
read by Tristan Morris
Part of the MIT Press Essential Knowledge series
In recent years, the astronomical rise of tech giants like Amazon, Apple, Meta, and Microsoft has been criticized as anticompetitive, and many have wondered if antitrust law can help protect workers and consumers. In Tech Monopoly, Herbert Hovenkamp explores competition problems in a wide range of high-tech firms, from those that sell purely digital products, such as video streaming, search, software, or email services, to others that sell more traditional "tactile" products, such as hardware, clothing, groceries, or rides. He offers a realistic look at the powers and limitations of antitrust law in tech markets with an assessment that is as comprehensive as it is accessible.
After a general introduction to antitrust law, “Tech Monopoly” considers how competitive harm should be assessed in these markets. Then Hovenkamp looks at the role of large digital platforms, including Amazon, Alphabet, Apple, Meta, and Microsoft, and considers whether their size alone is an antitrust problem or if the concern should be limited to market power. Finally, the author addresses the very difficult problem of remedies. Should we "break up" big tech, and if so, how? What kind of breakup of these firms would make users or others better off? And if breakups are not the only possible antitrust fix, are there more effective and less disruptive alternatives?
