Length-Scale Dependent Phonon Interactions

by Subhash L. Shindé Gyaneshwar P. Srivastava

This book presents a comprehensive description of phonons and their interactions in systems with different dimensions and length scales. Internationally-recognized leaders describe theories and measurements of phonon interactions in relation to the design of materials with exotic properties such as metamaterials, nano-mechanical systems, next-generation electronic, photonic, and acoustic devices, energy harvesting, optical information storage, and applications of phonon lasers in a variety of fields. The emergence of techniques for control of semiconductor properties and geometry has enabled engineers to design structures in which functionality is derived from controlling electron behavior. As manufacturing techniques have greatly expanded the list of available materials and the range of attainable length scales, similar opportunities now exist for designing devices whose functionality is derived from controlling phonon behavior. However, progress in this area is hampered by gaps in our knowledge of phonon transport across and along arbitrary interfaces, the scattering of phonons with crystal defects, interface roughness and mass-mixing, delocalized electrons/collective electronic excitations, and solid acoustic vibrations when these occur in structures with small physical dimensions. This book provides a comprehensive description of phonons and their interactions in systems with different dimensions and length scales. Theories and measurements of phonon interactions are described in relation to the design of materials with exotic properties such as metamaterials, nano-mechanical systems, next-generation electronic, photonic, and acoustic devices, energy harvesting, optical information storage, and applications of phonon lasers in a variety of fields.

Lenin's Laureate: Zhores Alferov's Life in Communist Science (Transformations: Studies in the History of Science and Technology)

by Paul R. Josephson

The life and work of a leading Soviet physicist and an exploration of the strengths and weaknesses of Soviet science from Stalin through Gorbachev.In 2000, Russian scientist Zhores Alferov shared the Nobel Prize for Physics for his discovery of the heterojunction, a semiconductor device the practical applications of which include LEDs, rapid transistors, and the microchip. The Prize was the culmination of a career in Soviet science that spanned the eras of Stalin, Khrushchev, and Gorbachev—and continues today in the postcommunist Russia of Putin and Medvedev. In Lenin's Laureate, historian Paul Josephson tells the story of Alferov's life and work and examines the bureaucratic, economic, and ideological obstacles to doing state-sponsored scientific research in the Soviet Union. Lenin and the Bolsheviks built strong institutions for scientific research, rectifying years of neglect under the Czars. Later generations of scientists, including Alferov and his colleagues, reaped the benefits, achieving important breakthroughs: the first nuclear reactor for civilian energy, an early fusion device, and, of course, the Sputnik satellite. Josephson's account of Alferov's career reveals the strengths and weaknesses of Soviet science—a schizophrenic environment of cutting-edge research and political interference. Alferov, born into a family of Communist loyalists, joined the party in 1967. He supported Gorbachev's reforms in the 1980s, but later became frustrated by the recession-plagued postcommunist state's failure to fund scientific research adequately. An elected member of the Russian parliament since 1995, he uses his prestige as a Nobel laureate to protect Russian science from further cutbacks.Drawing on extensive archival research and the author's own discussions with Alferov, Lenin's Laureate offers a unique account of Soviet science, presented against the backdrop of the USSR's turbulent history from the revolution through perestroika.

Lenkverfahren: Eine Einführung in die Theorie und Praxis der Flugkörperlenkung

by Thomas Kuhn Werner Grimm

Das Buch bietet eine Einführung in die wichtigsten Methoden der Flugkörperlenkung. Im Rahmen eines historischen Abrisses wird die Frage geklärt, was überhaupt unter einem Lenkflugkörper zu verstehen ist. Es folgen Grundbegriffe und Definitionen wie z.B. die der erforderlichen Koordinatensysteme. Die Einbettung des Systems Lenkung in das Gesamtsystem Flugkörper wird beschrieben. Die wichtigsten Lenkverfahren sind die Proportionalnavigation, die Zieldeckungslenkung und die Raketenlenkung auf der Basis des Required-Velocity-Konzeptes. Jedem der drei Verfahren ist jeweils ein Kapitel gewidmet. Unter der Überschrift "Realisierungsaspekte" geht es um die praktische Umsetzung der Lenkverfahren. Auf oberster Ebene bewerkstelligt die Missionssteuerung das Umschalten in die verschiedenen Phasen der Flugbahn. Zur Auswertung eines Lenkgesetzes muss die Relativgeometrie Flugkörper / Ziel erfasst bzw. geschätzt werden. Dazu gibt es verschiedene Suchkopftechnologien bzw. Schätzverfahren (Kalman-Filter). Fast alle beschriebenen Methoden werden mit Simulationsergebnissen mit einem einfachen Flugkörpermodell veranschaulicht.

Lenny Cyrus, School Virus

by Joe Schreiber Matt Smith

It seemed so logical at first. Fourteen-year-old Lenny Cyrus had loved Zooey Andrews since third grade. All the boy genius needed to do to win her heart, surely, was shrink down to the size of an amoeba, ooze into a gelatin capsule, and have his friend Harlan slip it (him!) into Zooey's Diet Coke. Told in three voices, this fantastical middle grade novel takes Lenny deep into Zooey's loud, splashing innards, where a talking astrovirus named Astro has a bad attitude about white blood cells ("self-righteous pus-bags") and aromatic hormones disco dance. The question is, will Lenny and Zooey survive his crazy experiment in nanotechnology? The worst part comes when Lenny inadvertently triggers an infection in Zooey's brain, and her whole body goes into lockdown. Can Lenny rescue Zooey before his time is up? Lenny Cyrus is determined to find his way into Zooey's heart. Literally.

Leominster Firefighting (Images of America)

by Roger H. Lapointe

In 1820, a group of Leominster volunteers formed Engine Company No. 1 "in the interests of protecting the rights of the settlers in case of fire." Since then, more than 1,400 individuals have served as firefighters for the citizens of Leominster, each of them leaving behind a legacy that will never be forgotten. Leominster Firefighting features images, memorabilia, and photographs from the early days of the hand tubs and horse-drawn hose carts of the 1800s to the 20th century when motorized apparatus arrived. It provides a glimpse into the many traditions that have been passed from one generation to the next and a look into how fire has changed Leominster.

Leonardo da Vinci: La biografía

by Walter Isaacson

El aclamado autor de los best sellers Steve Jobs y Einstein nos vuelve a cautivar con la vida del genio más creativo de la historia en esta fascinante biografía. Basándose en las miles de páginas de los cuadernos manuscritos de Leonardo y nuevos descubrimientos sobre su vida y su obra, Walter Isaacson teje una narración que conecta el arte de Da Vinci con sus investigaciones científicas, y nos muestra cómo el genio del hombre más visionario de la historia nació de habilidades que todos poseemos y podemos estimular, tales como la curiosidad incansable, la observación cuidadosa y la imaginación juguetona. Su creatividad, como la de todo gran innovador, resultó de la intersección entre la tecnología y las humanidades. Despellejó y estudió el rostro de numerosos cadáveres, dibujó los músculos que configuran el movimiento de los labios y pintó la sonrisa más enigmática de la historia, la de la Mona Lisa. Exploró las leyes de la óptica, demostró como la luz incidía en la córnea y logró producir esa ilusión de profundidad en la Última cena. La habilidad de Leonardo da Vinci para combinar arte y ciencia -esplendorosamente representada en el Hombre de Vitruvio- continúa siendo la regla de oro de la innovación. La apasionante vida de este gran hombre debe recordarnos la importancia de inculcar el conocimiento, pero sobre todo la voluntad contagiosa de cuestionarlo: ser imaginativos y pensar de manera diferente.

Leonardo Da Vinci: Cong Fan Ren Dao Tian Cai De Chuang Zao Li Mi Ma = Leonardo Da Vinci

by Walter Isaacson

<P>Based on thousands of pages from Leonardo’s astonishing notebooks and new discoveries about his life and work, Walter Isaacson weaves a narrative that connects his art to his science. He shows how Leonardo’s genius was based on skills we can improve in ourselves, such as passionate curiosity, careful observation, and an imagination so playful that it flirted with fantasy. He produced the two most famous paintings in history, The Last Supper and the Mona Lisa. But in his own mind, he was just as much a man of science and technology. <P>With a passion that sometimes became obsessive, he pursued innovative studies of anatomy, fossils, birds, the heart, flying machines, botany, geology, and weaponry. His ability to stand at the crossroads of the humanities and the sciences, made iconic by his drawing of Vitruvian Man, made him history’s most creative genius. His creativity, like that of other great innovators, came from having wide-ranging passions. He peeled flesh off the faces of cadavers, drew the muscles that move the lips, and then painted history’s most memorable smile. He explored the math of optics, showed how light rays strike the cornea, and produced illusions of changing perspectives in The Last Supper. <P>Isaacson also describes how Leonardo’s lifelong enthusiasm for staging theatrical productions informed his paintings and inventions. Leonardo’s delight at combining diverse passions remains the ultimate recipe for creativity. So, too, does his ease at being a bit of a misfit: illegitimate, gay, vegetarian, left-handed, easily distracted, and at times heretical. His life should remind us of the importance of instilling, both in ourselves and our children, not just received knowledge but a willingness to question it—to be imaginative and, like talented misfits and rebels in any era, to think different. <P><b>A New York Times Bestseller</b>

by Thomas J. Misa

Now updated — A comprehensive, 500-year history of technology in society.Historian Thomas J. Misa's sweeping history of the relationship between technology and society over the past 500 years reveals how technological innovations have shaped—and have been shaped by—the cultures in which they arose. Spanning the preindustrial past, the age of scientific, political, and industrial revolutions, as well as the more recent eras of imperialism, modernism, and global security, this compelling work evaluates what Misa calls "the question of technology."In this edition, Misa brings his acclaimed text up to date by drawing on current scholarship while retaining sharply drawn portraits of individual people, artifacts, and systems. Each chapter has been honed to relate to contemporary concerns. Globalization, Misa argues, looks differently considering today's virulent nationalism, cultural chauvinism, and trade wars. A new chapter focuses on the digital age from 1990 to 2016. The book also examines how today's unsustainable energy systems, insecure information networks, and vulnerable global shipping have helped foster geopolitical risks and instability and takes a look at the coronavirus pandemic from the perspective of Wuhan, China's high-tech district. A masterful analysis of how technology and culture have influenced each other over five centuries, Leonardo to the Internet frames a history that illuminates modern-day problems and prospects faced by our technology-dependent world.

Leonardo's Art Workshop: Invent, Create, and Make Steam Projects Like a Genius (Leonardo's Workshop)

by Amy Leidtke

Leonardo’s Art Workshop leads children on an interactive adventure through key art concepts by following the multidisciplinary approach of the Renaissance period polymath Leonardo da Vinci: experimenting, creating projects, and exploring how art intersects with science and nature. Photos of Leonardo’s own notebooks, paintings, and drawings provide visual inspiration. More than 500 years ago, Leonardo knew that the fields of science, technology, engineering, art, and mathematics (STEAM) are all connected. The insatiably curious Leonardo examined not just the outer appearance of his art subjects, but the science that explained them. He began his studies as a painter, but his curiosity, diligence, and genius made him also a master sculptor, architect, designer, scientist, engineer, and inventor. The Leonardo’s Workshop series shares this spirit of multidisciplinary inquiry with children through accessible, engaging explanations and hands-on learning. Following Leonardo’s example, this fascinating book harnesses children’s innate curiosity to explore the foundational elements of art—color, shadow and light, lines and patterns, forms and structures, and optics and special effects—and the science behind them. After each concept is explained using science, history, and real-world examples, kids can experience the principles first-hand with step-by-step STEAM projects, including: ·Create paints and dyes from food ·Harness a rainbow with a prism ·Build a camera obscura ·Make your own sundial ·Practice blind contour drawing ·Create a one-point perspective drawing ·Make an infinity scopeInsight from other great artists and scientists—such as Sir Isaac Newton, Sandro Botticelli, Paul Klee, and Leonardo Pisano Fibonacci—are woven into the lessons throughout. Introduce vital STEAM skills through visually rich, hands-on learning with Leonardo’s Art Workshop.
