In this Very Short Introduction, Paul Klenerman describes the immune system, and how it works in health and disease. He considers how the immune system evolved, the basic rules that govern its behavior, and the major health threats where it is important. Paul Klenerman also explains how things can go wrong when there is too little or too much immunity. The book also addresses what we learned about the immune system from the COVID-19 pandemic and how that has influenced thinking about future pandemics.

In Killed by a Traffic Engineer, civil engineering professor Wes Marshall shines a spotlight on how little science there is behind the way that our streets are engineered, which leaves safety as an afterthought. While traffic engineers are not trying to cause deliberate harm to anyone, he explains, they are guilty of creating a transportation system whose designs remain largely based on plausible, but unproven, conjecture.

A system can describe what we see (the solar system), operate a computer (Windows 10), or be made on a page (the 14 engineered lines of a sonnet). In this book, Clifford Siskin shows that system is best understood as a genre - a form that works physically in the world to mediate our efforts to understand it. Indeed, many Enlightenment authors published works they called "system" to compete with the essay and the treatise.

Knowing where to start when learning a new skill can be a challenge, especially when the topic seems so vast. There can be so much information available that you can't even decide where to start. Or worse, you start down the path of learning and quickly discover too many concepts, commands, and nuances that aren't explained. What you learn in Linux for Beginners applies to any Linux environment including Ubuntu, Debian, Linux Mint, RedHat, Fedora, OpenSUSE, Slackware, and more.

This book is based on W. Edwards Deming’s famous concept “The System of Profound Knowledge”. Although he conceived it before the internet, or even artificial intelligence, became popular, the idea anticipated intelligent algorithms, and the efficient collaborated between human and AI. A system does not only connect employees with colleagues, but also with values, ideas, regulations, providers, clients, and other external stakeholders.

Few subjects are more fundamental to modern life than electrical power. The systems that generate, transport, and distribute electricity are among the most essential contributors to modern industry, development, and everyday living. As energy demand grows and, with it, the electric power industry, more and more non-electrical professionals must make important policy and administrative decisions regarding the systems that power our world.

Living busily on Planet Earth, we rarely remember that we actually inhabit only a miniscule part of the universe. In The Planets and the Solar System, Jen Green paints the wider picture, and takes us on a journey across billions of kilometers in our galaxy, from our Sun to near and distant planets. Some, like Mercury, have a molten core surrounded with crust and spins quickly; Jupiter, on the other hand, is a big ball of gas.

This bundle takes a no-nonsense approach to allow the user to learn in a simple to understand language. It goes in-depth and provides the listener with an up close and personal look into all it can offer. It offers tips, tricks, and features that often go undiscovered.

Toxic Water, Toxic System exposes the consequences of a seemingly anonymous authoritarian state willing to maintain white supremacy at any cost—including poisoning an entire city and shutting off water to thousands of people. Weaving together narratives of frontline activists along with archival data, Michael Mascarenhas provides a powerful exploration of the political alliances and bureaucratic mechanisms that uphold inequality.

The American standard system of measurement is a unique and odd thing to behold with its esoteric, inconsistent standards: 12 inches in a foot, three feet in a yard, 16 ounces in a pound, 100 pennies to the dollar. For something as elemental as counting and estimating the world around us, it seems like a confusing tool to use. So how did we end up with it? Most of the rest of the world is on the metric system, and for a time in the 1970s America appeared ready to make the switch.

Haptics, or haptic sensing, refers to the ability to identify and perceive objects through touch. This is active touch, involving exploration of an object with the hand rather than the passive sensing of a vibration or force on the skin. The development of new technologies, including prosthetic hands and tactile surfaces for flat screen displays, depends on our knowledge of haptics. In this volume in the MIT Press Essential Knowledge series, Lynette Jones offers an accessible overview of haptics, or active touch sensing, and its applications.

In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another 60 years before they discovered that this wavelength was in fact iron being burned at a staggering three million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible.

Over the last decade, scientists have discovered the importance and widespread presence in the body of a remarkable family of proteins known as prion proteins. Research links various types of prion proteins to neurodegenerative diseases such as Parkinson's and Alzheimer's—and this has fueled the search for new drugs that could halt the progression of these terrible disorders. Other discoveries have revealed the essential roles prion proteins play in memory and immunity, and the part they may have played in the beginnings of life on our planet.

What is our immune system, and how does it work? A vast array of cells, proteins and chemicals spring into action whenever our bodies are damaged, but immunity is not something you can see, touch, or feel. It can fight off malicious bacteria and viruses, locate cancerous growths, and even rewire our brains—but sometimes our own tissues can get caught in its crossfire, with catastrophic consequences. Humans may be the most disease-ridden animals on the planet. Professor John Trowsdale shows how the immune system protects us, and how our bodies invest huge resources to keep it running.

From the citrus groves of Sicily to a taco in Mexico City, In Search of the Perfect Peach takes you on a journey in the pursuit of flavor, with Franco revealing at every step how this incredibly simple desire can lead to radical change. Throughout, he offers us a deeply optimistic vision of how we as consumers can follow flavor to fix the food system and bring joy to our every meal.

In 1977, two spacecraft were launched from Earth to explore the outer Solar System, and incredibly, the now-ancient technology from the 1970s is still working, sending daily reports back to the planet that sent the two robotic envoys on their way, over 40 years ago. Voyager 1 and 2 have done far more than accomplish their original missions. In fact, they are now exploring interstellar space, far beyond the outer planets, in the cold wasteland between the stars.

In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets—and alien life—beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars—thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration.

From two of the world's top scientists and one of the world's top science writers (all parents), Dirt Is Good is a Q&A-based guide to everything you need to know about kids and germs.
