Lenin's Laureate: Zhores Alferov's Life in Communist Science (Transformations: Studies in the History of Science and Technology)
by Paul R. JosephsonThe 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 GrimmDas 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 SmithIt 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. LapointeIn 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
by Walter Isaacson<P>He was history’s most creative genius. What secrets can he teach us? The author of the acclaimed bestsellers Steve Jobs, Einstein, and Benjamin Franklin brings Leonardo da Vinci to life in this exciting new biography. <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>
Leonardo da Vinci: La biografía
by Walter IsaacsonEl 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 to the Internet: Technology and Culture from the Renaissance to the Present (Johns Hopkins Studies in the History of Technology)
by Thomas J. MisaNow 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 LeidtkeLeonardo’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.
Leonardo's Laptop: Human Needs and the New Computing Technologies
by Ben Shneiderman2003 IEEE-USAB Award for Distinguished Literary Contributions Furthering Public Understanding of the Profession. and Selected as a Finalist in the category of Computer/Internet in the 2002 Independent Publisher Book Awards (IPPYs) presented by Independent Publisher Magazine Ben Shneiderman's book dramatically raises computer users' expectations of what they should get from technology. He opens their eyes to new possibilities and invites them to think freshly about future technology. He challenges developers to build products that better support human needs and that are usable at any bandwidth. Shneiderman proposes Leonardo da Vinci as an inspirational muse for the "new computing." He wonders how Leonardo would use a laptop and what applications he would create. Shneiderman shifts the focus from what computers can do to what users can do. A key transformation is to what he calls "universal usability," enabling participation by young and old, novice and expert, able and disabled. This transformation would empower those yearning for literacy or coping with their limitations. Shneiderman proposes new computing applications in education, medicine, business, and government. He envisions a World Wide Med that delivers secure patient histories in local languages at any emergency room and thriving million-person communities for e-commerce and e-government. Raising larger questions about human relationships and society, he explores the computer's potential to support creativity, consensus-seeking, and conflict resolution. Each chapter ends with a Skeptic's Corner that challenges assumptions about trust, privacy, and digital divides.
Leonhard Euler
by Ronald S. CalingerThis is the first full-scale biography of Leonhard Euler (1707-83), one of the greatest mathematicians and theoretical physicists of all time. In this comprehensive and authoritative account, Ronald Calinger connects the story of Euler's eventful life to the astonishing achievements that place him in the company of Archimedes, Newton, and Gauss. Drawing chiefly on Euler's massive published works and correspondence, which fill more than eighty volumes so far, this biography sets Euler's work in its multilayered context--personal, intellectual, institutional, political, cultural, religious, and social. It is a story of nearly incessant accomplishment, from Euler's fundamental contributions to almost every area of pure and applied mathematics--especially calculus, number theory, notation, optics, and celestial, rational, and fluid mechanics--to his advancements in shipbuilding, telescopes, ballistics, cartography, chronology, and music theory.The narrative takes the reader from Euler's childhood and education in Basel through his first period in St. Petersburg, 1727-41, where he gained a European reputation by solving the Basel problem and systematically developing analytical mechanics. Invited to Berlin by Frederick II, Euler published his famous Introductio in analysin infinitorum, devised continuum mechanics, and proposed a pulse theory of light. Returning to St. Petersburg in 1766, he created the analytical calculus of variations, developed the most precise lunar theory of the time that supported Newton's dynamics, and published the best-selling Letters to a German Princess--all despite eye problems that ended in near-total blindness. In telling the remarkable story of Euler and how his achievements brought pan-European distinction to the Petersburg and Berlin academies of sciences, the book also demonstrates with new depth and detail the central role of mathematics in the Enlightenment.Some images inside the book are unavailable due to digital copyright restrictions.
Leonid Isaakovich Mandelstam
by Alexander PechenkinThis biography of the famous Soviet physicist Leonid Isaakovich Mandelstam (1889-1944), who became a Professor at Moscow State University in 1925, describes his contributions to both physics and technology, as well as discussing the scientific community which formed around him, usually called the Mandelstam school. Mandelstam's life story is thereby placed in its proper cultural context. The following more general issues are taken under consideration: the impact of German scientific culture on Russian science; the problems and fates of Russian intellectuals during the revolutionary and post-revolutionary years; the formation of the Soviet Academy of Sciences; and transformation of the system of higher education in the USSR during the 1920's and 1930's. The author shows that Mandelstam's fundamental writings and his lectures notes allow to reconstruct his philosophy of science and his approach to the social and ethical functions of science and science education. That reconstruction is enhanced through extensive use of hitherto unpublished archival material as well as the transcripts of personal interviews conducted by the author.

Leopold Koppel: Einfluss und Macht eines Financiers im Hintergrund (1854–1933)
by Hans H. LembkeLeopold Koppel (1854 –1933) war zu seiner Zeit eine der bedeutendsten Persönlichkeiten des deutschen Wirtschaftslebens, als Investor und Stifter. Sein erster großer Coup gelang ihm in der Gasbeleuchtung, sein zweiter mit elektrischem Licht – und der Marke Osram. Mittels Übernahme chancenreicher Unternehmen besetzte er auch in der Hotellerie und Gastronomie erste Plätze. Neue Dimensionen erschloss er sich als Wissenschaftsmäzen mit Allerhöchster Anerkennung. Als erstrangiger Financier der Kaiser-Wilhelm-Gesellschaft setzte er auf die Physikalische Chemie, die er auch rüstungs-industriell nutzte. In den Weimarer Jahren schwanden Tatkraft und Bedeutung, doch selbst den Rückbau seines Konzerns unternahm er strategisch. Leopold Koppel starb im Spätsommer 1933; die Enteignung blieb ihm erspart.

Lesotho Highlands Water Project: Communication Practices for Governance and Sustainability Improvement
by Leonardo Mazzei Lawrence J. M. Haas Donal O'LearyThis paper considers the multi-faceted lessons of the Lesotho Highlands Water Project and how the project can serve as a model of mutually beneficial development, though demonstrating the benefits of a bilateral governmental cooperative approach in the development of an international river. These benefits include exceeding the impact of individual national approaches and strengthening political cooperation among all participants. This model is particularly relevant since approximately 40 percent of the world's population lives in transboundary river basins and more than 90 percent of the world's population lives within countries that share these basins.
Lesser Beasts: A Snout-to-Tail History of the Humble Pig
by Mark EssigUnlike other barnyard animals, which pull plows, give eggs or milk, or grow wool, a pig produces only one thing: meat. Incredibly efficient at converting almost any organic matter into nourishing, delectable protein, swine are nothing short of a gastronomic godsend--yet their flesh is banned in many cultures, and the animals themselves are maligned as filthy, lazy brutes. As historian Mark Essig reveals in Lesser Beasts, swine have such a bad reputation for precisely the same reasons they are so valuable as a source of food: they are intelligent, self-sufficient, and omnivorous. What’s more, he argues, we ignore our historic partnership with these astonishing animals at our peril. Tracing the interplay of pig biology and human culture from Neolithic villages 10,000 years ago to modern industrial farms, Essig blends culinary and natural history to demonstrate the vast importance of the pig and the tragedy of its modern treatment at the hands of humans. Pork, Essig explains, has long been a staple of the human diet, prized in societies from Ancient Rome to dynastic China to the contemporary American South. Yet pigs’ ability to track down and eat a wide range of substances (some of them distinctly unpalatable to humans) and convert them into edible meat has also led people throughout history to demonize the entire species as craven and unclean. Today’s unconscionable system of factory farming, Essig explains, is only the latest instance of humans taking pigs for granted, and the most recent evidence of how both pigs and people suffer when our symbiotic relationship falls out of balance. An expansive, illuminating history of one of our most vital yet unsung food animals, Lesser Beasts turns a spotlight on the humble creature that, perhaps more than any other, has been a mainstay of civilization since its very beginnings--whether we like it or not.
