jeu de l'évolution biologique, chimique et physique, l'homme apparaît comme l'ultime et imparable aboutissement d'un "projet" en germe dans l'explosion primordiale voici 13,7 milliards d'années. Illusion d'optique ! En réalité, du Big Bang à Homo sapiens, ce ne fut qu'une suite de hasards et de nécessités qui fait de nous, et du monde tel qu'il est, plutôt une incongruité, ou si l'on préfère, un "miracle". De l'explosion originelle, qui manqua de faire "pschitt" comme un pétard mouillé, jusqu'à l'éruption cataclysmique d'un volcan géant à Sumatra, voilà 80 000 ans, qui faillit bien nous rayer de la saga du vivant, Hervé Ponchelet a identifié sept catastrophes principales grâce auxquelles, paradoxalement, nous devons, en dépit de tout, d'être là. C'est cette histoire vraie qui est ici contée, débarrassée des croyances mais intégrant les convergences entre science et mythes, replaçant les découvertes et les découvreurs dans leur contexte et l'évolution des idées, précisément informée mais conçue et rédigée à l'intention du public le plus large. À défaut de savoir où nous allons, sachons mieux d'où nous venons." -- 4e de couvEinstein in time and space: A life in 99 particles
Par Samuel Graydon. 2023
Walter Isaacson's Einstein meets Craig Brown's 99 Glimpses of Princess Margaret , in this innovative biography of the famous physicist…
told in ninety-nine dazzling vignettes. Most of us would agree that Albert Einstein's name is synonymous with "genius" and that his likeness is often used as a shorthand for all scientists, appearing everywhere from cartoons to textbooks. He has become more myth than man. That being the case, how best to capture his essence? In Einstein in Time and Space , talented young science journalist Samuel Graydon answers that question with an illuminating mosaic—99 intriguingly different particles that cumulatively reveal Einstein's contradictory and multitudinous nature. Glimpsed among these shards: a slacker who failed every subject but math, a job seeker who couldn't get hired, a lothario who courted many women, and a charmer who was the life of the party. As brilliant as he was inconsistent, Einstein was simultaneously an avid supporter of the NAACP and the fight for civil rights and someone capable of great prejudice. He was loved by many, known by few, and inspirational to a generation of young physicists. Graydon reveals every corner of Einstein's world: the false reporting that rocketed Einstein to fame nearly overnight, his effect on people he met merely in passing, even the remarkable posthumous journey of the famed physicist's brain. Entertaining, comforting, bolstering, and shocking, Einstein in Time and Space is the unique story of a man who redefined how we view our universe and our place within itFollowing the Good River: The Life and Times of Wa'xaid
Par Briony Penn. 2020
Based on recorded interviews and journal entries this major biography of Cecil Paul (Wa’xaid) is a resounding and timely saga…
featuring the trials, tribulations, endurance, forgiveness, and survival of one of North America’s more prominent Indigenous leaders. Born in 1931 in the Kitlope, Cecil Paul, also known by his Xenaksiala name, Wa’xaid, is one of the last fluent speakers of his people’s language. At age ten he was placed in a residential school run by the United Church of Canada at Port Alberni where he was abused. After three decades of prolonged alcohol abuse, he returned to the Kitlope where his healing journey began. He has worked tirelessly to protect the Kitlope, described as the largest intact temperate rainforest watershed in the world. Now in his late 80s, he resides on his ancestors’ traditional territory.Following upon the success of Wa'xaid's own book of personal essays, Stories from the Magic Canoe, Briony Penn's major biography of this remarkable individual will serve as a timely reminder of the state of British Columbia's Indigenous community, the environmental and political strife still facing many Indigenous communities, and the philosophical and personal journey of a remarkable man.Wa'xaid passed away at the age of 90 on December 3, 2020.Life in Two Worlds: A Coach's Journey from the Reserve to the NHL and Back
Par Ted Nolan. 2023
In 1997 Ted Nolan won the Jack Adams Award for best coach in the NHL. But he wouldn’t work in…
pro hockey again for almost a decade. What happened?Growing up on a First Nation reserve, young Ted Nolan built his own backyard hockey rink and wore skates many sizes too big. But poverty wasn’t his biggest challenge. Playing the game meant spending his life in two worlds: one in which he was loved and accepted and one where he was often told he didn’t belong.Ted proved he had what it took, joining the Detroit Red Wings in 1978. But when his on-ice career ended, he discovered his true passion wasn’t playing; it was coaching. First with the Soo Greyhounds and then with the Buffalo Sabres, Ted produced astonishing results. After his initial year as head coach with the Sabres, the club was being called the "hardest working team in professional sports." By his second, they had won their first Northeast Division title in sixteen years.Yet, the Sabres failed to re-sign their much-loved, award-winning coach.Life in Two Worlds chronicles those controversial years in Buffalo—and recounts how being shut out from the NHL left Ted frustrated, angry, and so vulnerable he almost destroyed his own life. It also tells of Ted’s inspiring recovery and his eventual return to a job he loved. But Life in Two Worlds is more than a story of succeeding against the odds. It’s an exploration of how a beloved sport can harbour subtle but devastating racism, of how a person can find purpose when opportunity and choice are stripped away, and of how focusing on what really matters can bring two worlds together.Reclaiming Diné history: the legacies of Navajo Chief Manuelito and Juanita
Par Jennifer Denetdale. 2007
In this groundbreaking book, the first Navajo to earn a doctorate in history seeks to rewrite Navajo history. Reared on…
the Navajo Nation in New Mexico and Arizona, Jennifer Nez Denetdale is the great-great-great-granddaughter of a well-known Navajo chief, Manuelito (1816-1894), and his nearly unknown wife, Juanita (1845-1910). Stimulated in part by seeing photographs of these ancestors, she began to explore her family history as a way of examining broader issues in Navajo historiography. Here she presents a thought-provoking examination of the construction of the history of the Navajo people (Diné, in the Navajo language) that underlines the dichotomy between Navajo and non-Navajo perspectives on the Diné past. Reclaiming Diné History has two primary objectives. First, Denetdale interrogates histories that privilege Manuelito and marginalize Juanita in order to demonstrate some of the ways that writing about the Diné has been biased by non-Navajo views of assimilation and gender. Second, she reveals how Navajo narratives, including oral histories and stories kept by matrilineal clans, serve as vehicles to convey Navajo beliefs and values. By scrutinizing stories about Juanita, she both underscores the centrality of women's roles in Navajo society and illustrates how oral tradition has been used to organize social units, connect Navajos to the land, and interpret the past. She argues that these same stories, read with an awareness of Navajo creation narratives, reveal previously unrecognized Navajo perspectives on the past. And she contends that a similarly culture-sensitive re-viewing of the Diné can lead to the production of a Navajo-centered history.

Tracking the Caribou Queen: Memoir of a Settler Girlhood
Par Margaret Macpherson. 2022
In this challenging memoir about her formative years in Yellowknife in the '60s and '70s, author Margaret Macpherson lays bare…
her own white privilege, her multitude of unexamined microaggressions, and how her childhood was shaped by the colonialism and systemic racism that continues today. Macpherson's father, first a principal and later a federal government administrator, oversaw education in the NWT, including the high school Margaret attended with its attached hostel: a residential facility mostly housing Indigenous children.Ringing with damning and painful truths, this bittersweet telling invites white readers to examine their own personal histories in order to begin to right relations with the Indigenous Peoples on whose land they live. Tracking the Caribou Queen is beautifully crafted to a purpose: poetic language and narrative threads dissect the trope that persisted through her girlhood, that of the Caribou Queen, a woman who seemed to embody extreme and contradictory stereotypes of Indigeneity. Here, Macpherson is not striving for a tidy ideal of "reconciliation"; what she is working towards is much messier, more complex and ambivalent and, ultimately, more equitable.Unbroken: My Fight for Survival, Hope, and Justice for Indigenous Women and Girls
Par Angela Sterritt. 2023
"A remarkable life story.... Angela Sterritt is a formidable storyteller and a passionate advocate." (Cherie Dimaline, author of The Marrow…
Thieves) "Sterritt's story is living proof of how courageous Indigenous women are." (Tanya Talaga, author of Seven Fallen Feathers and All Our Relations) In her memoir, Angela Sterritt shares her story from navigating life on the streets to becoming an award-winning journalist. As a teenager, she wrote in her notebook to survive. Now, she reports on cases of missing and murdered Indigenous women in Canada, showing how colonialism and racism create a society where Indigenous people are devalued. Unbroken is a story about courage and strength against all odds.Superfluid: How a Quantum Fluid Revolutionized Modern Science
Par J. G. Weisend II. 2023
Unless you are a specialist or watch a lot of obscure YouTube videos you have probably never heard of He…
II or superfluid helium. This substance, a unique liquid form of the element helium, is produced and used in multi-ton quantities to enable much of modern science. Altogether, He II is at the heart of more than a dozen large scale scientific facilities world-wide representing an investment of tens of billions of dollars. It cools the magnets and cavities that contain and accelerate the particle beams at the Large Hadron Collider and is also used in accelerators for the study of rare isotopes and nuclear astrophysics. This little known liquid is, in reality, one of the enabling technologies of the future. A manifestation of quantum mechanics, He II exhibits amazing behaviors. It can flow up the side of a container against gravity, it can move through small openings without friction, and it can transfer heat extremely efficiently via a mechanism not seen elsewhere in nature. This book tells the story of He II. It describes the discovery of the fluid, the observation and understanding of its behavior, the development of underlying theory and the evolution of He II from a laboratory curiosity to an industrial-scale coolant. The current and possible future applications of He II are described. Like all science and engineering, the story of He II is a human story and the role that personalities, politics, communication, cooperation and competition play in the development of He II is captured here as well. World-famous physicists such as Lev Landau, Richard Feynman, Peter Kapitza and Kurt Mendelssohn are key players in the story, while secret police from two different countries have a walk-on role. This work is meant for the general reader. Without assuming any expertise in physics, engineering or mathematics, it illuminates for the general public a little-known area of science and engineering and shows why it matters. As it turns out, it’s also a good story.Complex Systems Design & Management: Proceedings of the 14th International Conference on Complex Systems Design & Management CSD&M 2023 (Lecture Notes in Electrical Engineering #1085)
Par Daniel Krob, Xinguo Zhang, Lefei Li, Junchen Yao, Mengyu Guo. 2023
This book contains all refereed papers accepted during the 14th International Conference on Complex Systems Design & Management CSD&M 2023 that took place…
in Beijing, People’s Republic of China by the end October 2023. Mastering complex systems requires an integrated understanding of industrial practices as well as sophisticated theoretical techniques and tools. This explains the creation of an annual go-between European and Asian forum dedicated to academic researchers and industrial actors working on complex industrial systems architecting, modeling and engineering. These proceedings cover the most recent trends in the emerging field of complex systems, both from an academic and professional perspective. A special focus was put this year on “New Trends in Complex Systems Engineering.” The CSD&M series of conferences were initiated under the guidance of CESAM Community in Europe, managed by CESAMES. Its Asian version took place in Singapore for three consecutive sessions during 2014 and 2018. The fourth Asian edition was held in Beijing in hybrid with the Chinese Society of Aeronautics and Astronautics (CSAA) as the co-organizer in 2021. Since 2023, its European and Asian conferences merge into one, taking place in China and Europe in turn. CESAM Community aims in organizing the sharing of good practices in systems architecting and model-based systems engineering (MBSE) and certifying the level of knowledge and proficiency in this field through the CESAM certification. The CESAM systems architecting, and model-based systems engineering (MBSE) certification is especially currently the most disseminated professional certification in the world in this domain through more than 3,000 real complex system development projects on which it was operationally deployed and around 10,000 engineers who were trained on the CESAM framework at international level.Computational Simulation in Nanophotonics and Spectroscopy (SpringerBriefs in Applied Sciences and Technology)
Par Mengtao Sun, Xijiao Mu. 2023
Nanophotonics and spectroscopy has advanced rapidly in recent years. Experimental research on nanophotonics is very active. In addition to experimental…
research on the principles and applications of nanophotonics, computational simulation research on its various physical mechanisms and phenomena is equally important. The simulation of the optical properties of molecules or crystals, such as electronic spectra (absorption and emission spectra, etc.) and vibrational spectroscopy has extraordinary guiding significance for experiments. The current computational simulation technology can also explain and analyze the physical mechanisms behind phenomena. However, among the many computational simulation software programs available, the operation methods and application scenarios are different. The barrier for new users to conduct research with computational simulation is high. Even for researchers with some experience, it is not easy to develop a comprehensive understanding of the various software programs, keywords, programming languages and auxiliary programs. This book serves as an introductory book for beginners to get started with the technology, and a handbook for experienced readers to quickly look up for commands and script usage. It is a handy reference for graduate students and researchers engaged in the study of photonics and optics.How Mechanics Shaped the Modern World: A Contextual Introduction to Concepts and Applications
Par David H. Allen. 2023
This updated and augmented second edition covers the history of mechanics in such a way as to explain how this…
all-important discipline shaped our world. Like the first edition, Dr. Allen presents the material in an engaging, accessible manner, with many historic insights and thorough explanations of attending concepts. The text retains its coverage of classical mechanics, essentially Newtonian mechanics, and adds chapters on three additional topics that go well beyond classical mechanics: relativity, quantum/nanomechanics, and biomechanics.Mixed Boundary Problems in Solid Mechanics (UNITEXT #155)
Par Natalya Vaysfeld, Zinaida Zhuravlova. 2023
The book covers a wide range of subjects and techniques related to mixed boundary problems of elasticity from basic concepts…
to special techniques that are unlikely to appear in traditional university graduate courses. This book may also be of interest to industrial researchers who encounter defects such as cracks and inclusions of different materials in mechanisms under different localization and type of loading. So the topics present the application of mathematical mechanics of solid bodies notably in elasticity, showing the interconnection of elasticity and temperature that would normally treated independently. Theoretical and experimental results are expected to be useful for researchers investigating a wide range of materials including metals, composites, ceramics, polymers, biomaterials and nanomaterials under different mechanical and temperature loading. The aim of the book is to introduce an interdisciplinary audience to a variety of stress state phenomena occurring in elasticity near defects and edges of the bodies. The book is aimed at researchers, primarily but not exclusively graduate students, postdoctoral researchers, specialists from Aerospace and Civil Engineering, Materials Science, and Engineering Mechanics and should naturally also be of interest to specialists of Physics and Applied Mathematics.
