Book Description
Did alligators ever really live in New York's sewers? What's it like to explore the old aqueducts beneath the city? How many levels are beneath Grand Central Station? And how exactly did the pneumatic tube system that New York's post offices used to employ work? In this richly illustrated historical tour of New York's vast underground systems, Julia Solis answers all these questions and much, much more. New York Underground takes readers through ingenious criminal escape routes, abandoned subway stations, and dark crypts beneath lower Manhattan to expose the city's basic anatomy. While the city is justly famous for what lies above ground, its underground passages are equally legendary and tell us just as much about how the city works.

Book Description
A celebration of waiting throughout history, and of its importance for connection, understanding, and intimacy in human communication We have always been conscious of the wait for life-changing messages, whether it be the time it takes to receive a text message from your love, for a soldier’s family to learn news from the front, or for a space probe to deliver data from the far reaches of the solar system. In this book in praise of wait times, award-winning author Jason Farman passionately argues that the delay between call and answer has always been an important part of the message. Traveling backward from our current era of Twitter and texts, Farman shows how societies have worked to eliminate waiting in communication and how they have interpreted those times’ meanings. Exploring seven eras and objects of waiting—including pneumatic mail tubes in New York, Elizabethan wax seals, and Aboriginal Australian message sticks—Farman offers a new mindset for waiting. In a rebuttal to the demand for instant communication, Farman makes a powerful case for why good things can come to those who wait.

Book Description
Though originally attributed to his father, Jules Verne, due to an error on the part of the publisher, the short tale "An Express of the Future" was actually penned by Jules Verne's often-estranged son, Michel. The story is remarkable in its prescient description of future technologies, such as pneumatic tubes.

Book Description
The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory
