Petite histoire de l'Univers: du Big Bang à la fin du monde
Par Stephen Hawking. 2008
"C'est exactement ce que propose ce recueil de sept conférences sur le cosmos et la place que nous y tenons,…
avec cette idée que " la science devrait être compréhensible par tous et pas seulement par quelques spécialistes. " De la théorie de l'expansion de l'Univers à celle du Big Bang en passant par les trous noirs, la direction du temps ou les découvertes de Hubble, Hawking nous convie à un passionnant voyage." -- 4e de couvHistoire du monde en sept catastrophes
Par Hervé Ponchelet. 2007
"Si l'on rembobine le film de l'histoire du monde, de l'homme au Big Bang, tout s'enchaîne parfaitement bien. Par le…
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 itHow not to age: The scientific approach to getting healthier as you get older

This program is read by the author. Uncover the evidence-based science to slowing the effects of aging, from the New…
York Times bestselling author of the How Not to Die series When Dr. Michael Greger, founder of NutritionFacts.org, dove into the top peer-reviewed anti-aging medical research, he realized that diet could regulate every one of the most promising strategies for combating the effects of aging. We don't need Big Pharma to keep us feeling young—we already have the tools. In How Not to Age , the internationally renowned physician and nutritionist breaks down the science of aging and chronic illness and explains how to help avoid the diseases most commonly encountered in our journeys through life. Physicians have long treated aging as a malady, but getting older does not have to mean getting sicker. There are eleven pathways for aging in our bodies' cells and we can disrupt each of them. Processes like autophagy, the upcycling of unusable junk, can be boosted with spermidine, a compound found in tempeh, mushrooms, and wheat germ. Senescent "zombie" cells that spew inflammation and are linked to many age-related diseases may be cleared in part with quercetin-rich foods like onions, apples, and kale. And we can combat effects of aging without breaking the bank. Why spend a small fortune on vitamin C and nicotinamide facial serums when you can make your own for up to 2,000 times cheaper? Inspired by the dietary and lifestyle patterns of centenarians and residents of "blue zone" regions where people live the longest, Dr. Greger presents simple, accessible, and evidence-based methods to preserve the body functions that keep you feeling youthful, both physically and mentally. Brimming with expertise and actionable takeaways, How Not to Age lays out practical strategies for achieving ultimate longevityOutlive: The science and art of longevity
Par Peter Attia. 2023
#1 NEW YORK TIMES BESTSELLER • A groundbreaking manifesto on living better and longer that challenges the conventional medical thinking…
on aging and reveals a new approach to preventing chronic disease and extending long-term health, from a visionary physician and leading longevity expert "One of the most important books you’ll ever read."—Steven D. Levitt, New York Times bestselling author of Freakonomics Wouldn’t you like to live longer? And better? In this operating manual for longevity, Dr. Peter Attia draws on the latest science to deliver innovative nutritional interventions, techniques for optimizing exercise and sleep, and tools for addressing emotional and mental health. For all its successes, mainstream medicine has failed to make much progress against the diseases of aging that kill most people: heart disease, cancer, Alzheimer’s disease, and type 2 diabetes. Too often, it intervenes with treatments too late to help, prolonging lifespan at the expense of healthspan, or quality of life. Dr. Attia believes we must replace this outdated framework with a personalized, proactive strategy for longevity, one where we take action now, rather than waiting. This is not "biohacking," it’s science: a well-founded strategic and tactical approach to extending lifespan while also improving our physical, cognitive, and emotional health. Dr. Attia’s aim is less to tell you what to do and more to help you learn how to think about long-term health, in order to create the best plan for you as an individual. In Outlive , readers will discover: • Why the cholesterol test at your annual physical doesn’t tell you enough about your actual risk of dying from a heart attack. • That you may already suffer from an extremely common yet underdiagnosed liver condition that could be a precursor to the chronic diseases of aging. • Why exercise is the most potent pro-longevity "drug"—and how to begin training for the "Centenarian Decathlon." • Why you should forget about diets, and focus instead on nutritional biochemistry, using technology and data to personalize your eating pattern. • Why striving for physical health and longevity, but ignoring emotional health, could be the ultimate curse of all. Aging and longevity are far more malleable than we think; our fate is not set in stone. With the right roadmap, you can plot a different path for your life, one that lets you outlive your genes to make each decade better than the one beforeOn the brink of everything: grace, gravity, and getting old (BK life book)
Par Parker J Palmer. 2018
Drawing on eight decades of life -- and his career as a writer, teacher, and activist -- Palmer explores the…
questions age raises and the promises it holds. "Old," he writes, "is just another word for nothing left to lose, a time to dive deep into life, not withdraw to the shallows." But this book is not for elders only. It was written to encourage adults of all ages to explore the way their lives are unfolding. It's not a how-to-do-it book on aging, but a set of meditations in prose and poetry that turn the prism on the meaning(s) of one's life, refracting new light at every turn.

and resist ageism. During her own year of transition-a milestone birthday, a wedding anniversary, the emptying of the nest-Walrond, in the buoyant and luminous style her readers have come to love, does a deep dive into dimensions of getting older, including health, beauty, spirituality, connection, adventure, and meaning and purpose. Through conversations with social workers and neurologists, activists and clergy, Walrond satisfies her curiosity about why the dominant culture treats aging as a time of dwindling capacity. She also embarks on a series of experiments that help her rebel against convention: letting her hair go naturally gray, going on a silent retreat, revamping her health practices, and plotting her next adventure. Internalized ageism is not our only option; we can write a different story of aging than the one we've been handed. With wisdom from luminaries who light our way, Walrond helps us radiantly rebel against the fads and assumptions that hold us back, redefine the adventure of getting older, and create a shining future of expanded potential. We might even raise a little hell while we're at it!C'est mon corps: toutes les questions que se posent les femmes sur leur santé

NASA's Chandra X-ray Observatory and ESA's XMM-Newton Observatory have been the pioneering satellites for studying the Universe with X-rays and…
the cornerstone of X-ray spectroscopy since their launches more than 20 years ago. The onboard gratings provide us a unique opportunity to distinguish individual spectral lines from different atoms thanks to their high energy resolutions. Enormous discoveries have been achieved by these two missions when observing a variety of X-ray-emitting astronomical objects, such as black holes, supernova remnants, clusters of galaxies, and stars. However, the data are limited to fairly bright X-ray sources. The recent JAXA's mission Hitomi opened a new window of high-resolution X-ray spectroscopy thanks to its onboard X-ray calorimeter. Although this mission was shortly terminated due to a mishap, Hitomi left behind a few sets of observations awaiting more data mining. The first half of this book introduces the history of high-resolution X-ray spectroscopy and different generations of X-ray spectrometers. A tutorial guide on how to reduce, analyze, and understand the astronomical data from Chandra, XMM-Newton, and Hitomi is also included. The second half of the book reviews past results obtained by the high-resolution spectrometers on these missions on multiple topics and discusses possible discoveries by upcoming missions in the next decade.Grace in All Simplicity: Beauty, Truth, and Wonders on the Path to the Higgs Boson and New Laws of Nature
Par Robert N. Cahn, Chris Quigg. 2023
An enthralling and accessible account of humanity&’s quest to make sense of our physical world, told through interwoven tales of…
inspiration, tragedy, and triumph.How do the remarkable recent discoveries of the Higgs boson, dark matter, and dark energy connect with the equally revolutionary discoveries in centuries past? In Grace in All Simplicity, readers will delight in Cahn and Quigg's engaging prose and see how the infinite and the infinitesimal are joined. Today, physicists and astronomers are exploring distances from a billionth of a billionth of the human scale to the entire cosmos, and contemplating time intervals that range from less than a trillionth of a trillionth of a second out to far longer than the age of the universe. Leaving home in this metaphorical way requires devising new instruments that spectacularly expand our senses and conceiving original ways of thinking that expand our minds. This is at once an act of audacity and an exercise in humility. Grace in All Simplicity narrates the saga of how we have prospected for some of Nature&’s most tightly held secrets, the basic constituents of matter and the fundamental forces that rule them. Our current understanding of the world (and universe) we inhabit is the result of curiosity, diligence, and daring, of abstraction and synthesis, and of an abiding faith in the value of exploration. In these pages we will meet scientists of both past and present. These men and women are professional scientists and amateurs, the eccentric and the conventional, performers and introverts. Scientists themselves, Cahn and Quigg convey their infectious joy as they search for new laws of nature. Join the adventure as scientists ascend mountain tops and descend into caverns deep underground, travel to the coldest places on Earth, and voyage back in time to near the birth of the Universe. Visit today&’s great laboratories and the astounding instruments they house. Grace in All Simplicity is a thrilling voyage filled with improbable discoveries and the extraordinary community of people who make them. Together, we will travel the path to the Higgs boson, weigh the evidence for subliminal dark matter, and learn what makes scientists invoke a mysterious agent named "dark energy." We will behold the emergence of a compelling picture of matter and forces, simple in its structure, graceful in the interplay of its parts, but still tantalizingly incomplete.Introduction to String Theory (Theoretical and Mathematical Physics)
Par Sergio Cecotti. 2023
Graduate students typically enter into courses on string theory having little to no familiarity with the mathematical background so crucial…
to the discipline. As such, this book, based on lecture notes, edited and expanded, from the graduate course taught by the author at SISSA and BIMSA, places particular emphasis on said mathematical background. The target audience for the book includes students of both theoretical physics and mathematics. This explains the book’s "strange" style: on the one hand, it is highly didactic and explicit, with a host of examples for the physicists, but, in addition, there are also almost 100 separate technical boxes, appendices, and starred sections, in which matters discussed in the main text are put into a broader mathematical perspective, while deeper and more rigorous points of view (particularly those from the modern era) are presented. The boxes also serve to further shore up the reader’s understanding of the underlying math. In writing this book, the author’s goal was not to achieve any sort of definitive conciseness, opting instead for clarity and "completeness". To this end, several arguments are presented more than once from different viewpoints and in varying contexts.Guide to Modern Physics: Using Mathematica for Calculations and Visualizations
Par James W. Rohlf. 2024
This is a "how to guide" for making beginning calculations in modern physics. The academic level is second year college…
physical science and engineering students. The calculations are performed in Mathematica, and stress graphical visualization, units, and numerical answers. The techniques show the student how to learn the physics without being hung up on the math. There is a continuing movement to introduce more advanced computational methods into lower-level physics courses. Mathematica is a unique tool in that code is written as "human readable" much like one writes a traditional equation on the board. Key Features: Concise summary of the physics concepts. Over 300 worked examples in Mathematica. Tutorial to allow a beginner to produce fast results. The companion code for this book can be found here: https://physics.bu.edu/~rohlf/code.html James Rohlf is a Professor at Boston University. As a graduate student he worked on the first experiment to trigger on hadron jets with a calorimeter, Fermilab E260. His thesis (G. C. Fox, advisor, C. Barnes, R. P. Feynman, R. Gomez) used the model of Field and Feynman to compare observed jets from hadron collisions to that from electron-positron collisions and made detailed acceptance corrections to arrive at first the measurement of quark-quark scattering cross sections. His thesis is published in Nuclear Physics B171 (1980) 1. At the Cornell Electron Storage Rings, he worked on the discovery of the Upsilon (4S) resonance and using novel event shape variables developed by Stephen Wolfram and his thesis advisor, Geoffrey Fox. He performed particle identification of kaons and charmed mesons to establish the quark decay sequence, b –> c. At CERN, he worked on the discovery of the W and Z bosons and measurement of their properties. Presently, he is working on the Compact Muon Solenoid (CMS) experiment at the CERN Large Hadron Collider (LHC) which discovered the Higgs boson and is searching for new phenomena beyond the standard model.
