Interpreting the Modern World
After teaching world history to college freshmen for two decades, the author was dissatisfied with the available textbooks, which smoothed over thorny historical debates in favor of uncontroversial, seamless, and bland narratives. Because students did not have to use the historical facts they read to answer questions that they themselves cared about concerning the current world, they rarely recalled the facts long after an exam. So, the author wrote this text to help his students enter into open-ended historical conversations. They explore the Enlightenment, and decide if it is a hypocritical screen for white male privilege or a slow-unfolding tool for universal liberation. They consider the...
Structural Health Monitoring 2003
Important new information on sensors, monitoring, prognosis, networking, and planning for safety and maintenance.
Nanotube Superfiber Materials
This chapter investigates the use of carbon nanotube (CNT) sensor thread in distributed structural health monitoring (SHM) systems, specifically as embedded damage and strain sensors. The CNT sensor thread has shown potential to be integrated into/onto composite materials to provide confident damage detection, localization, and characterization in complex geometries without complicated detection algorithms and minimal sensing channels. This chapter articulates current work done with CNT thread in Nanoworld Laboratories, specifically CNT thread performance as a sensor; past, current, and future embedded sensing work; and potential SHM design architectures for aircraft, along with a descriptio...
Nanotube Superfiber Materials
Nanotube Superfiber Materials refers to different forms of macroscale materials with unique properties constructed from carbon nanotubes. These materials include nanotube arrays, ribbons, scrolls, yarn, braid, and sheets. Nanotube materials are in the early stage of development and this is the first dedicated book on the subject. Transitioning from molecules to materials is a breakthrough that will positively impact almost all industries and areas of society. Key properties of superfiber materials are high flexibility and fatigue resistance, high energy absorption, high strength, good electrical conductivity, high maximum current density, reduced skin and proximity effects, high thermal cond...

Xenozoic
"What a strange new world, to have such creatures in it!" Forced into hiding by a global ecological cataclysm, humans emerge from their underground warrens half a millennium later to discover that the Earth has been totally transformed. All of the familiar flora and fauna are gone, replaced by a radically altered natural order populated by rampaging dinosaurs and strange new creatures. It takes guts, grim determination, ingenuity and a whole lot of old-fashioned luck just to survive, much less thrive, in this alien wilderness--all qualities that ace mechanic Jack Tenrec, lovely scientist Hannah Dundee and their friends possess in abundance. But even the worthiest of these hardy souls are har...
Faster, Smarter, Greener
A call to redefine mobility so that it is connected, heterogeneous, intelligent, and personalized, as well as sustainable, adaptable, and city-friendly. The twentieth century was the century of the automobile; the twenty-first will see mobility dramatically re-envisioned. Automobiles altered cityscapes, boosted economies, and made personal mobility efficient and convenient for many. We had a century-long love affair with the car. But today, people are more attached to their smartphones than their cars. Cars are not always the quickest mode of travel in cities; and emissions from the rapidly growing number of cars threaten the planet. This book, by three experts from industry and academia, en...
Nanotube Superfiber Materials
Multiscale laminated composite materials are formed by adding carbon nanotube (CNT) materials to microfiber laminated composites. CNTs reinforce the weak failure modes of laminated composites. Laminated composite materials provide high specific strength and high performance but have low interlaminar shear modulus and shear strength due to the lack of fiber in the transverse or out-of-plane direction. The weak interlaminar property may lead to premature failure of composite structures. Therefore, it is necessary to reinforce polymeric laminated composites in the transverse direction. CNT materials have excellent mechanical, thermal and electrical properties and are integrated into polymeric c...
