"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
By 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 itSincère ou tricheuse?: roman (J'ai lu #3017.

Dynamics and Kinetics in Structural Biology: Unravelling Function Through Time-Resolved Structural Analysis
By Eaton E. Lattman, Keith Moffat. 2024
Dynamics and Kinetics in Structural Biology Understand the latest experimental tools in structural biology with this pioneering work Structural biology…
seeks to understand the chemical mechanisms and functions of biological molecules, such as proteins, based on their atomic structures. Until recently, these structures have been studied only statically, using procedures which deliberately freeze atomic motion. However, freezing eliminates the rapid structural motions so essential to biological activity and function; the molecules are inactive. But with the recent development of X-ray free electron laser (XFEL) sources, efforts to conduct dynamic experiments have expanded using the principles of dynamics and kinetics to capture active biological molecules as they function. Dynamics and Kinetics in Structural Biology promotes the development of these experiments and their successful application. It grounds readers in the foundational principles of dynamics and kinetics; proceeds through extended discussions of experimental procedures and data analysis techniques; and explores experimental frontiers in structural dynamics. The book will aid researchers to gather and interpret cutting-edge data on the dynamic structure of biological molecules, under conditions where they retain their biological functions. Dynamics and Kinetics in Structural Biology offers readers: Authorship by founding figures in the field In-depth presentation of time-resolved X-ray crystallography, solution scattering, and more A pioneering contribution to a rapidly developing field of study Dynamics and Kinetics in Structural Biology is essential reading for graduate students, scientists, researchers and industry professionals engaged in structural studies of biological systems. Industry professionals considering dynamic studies in the development of new product lines will also benefit.This book explores magnetic properties and critical temperatures in inverse ferrite Fe₃⁺(M₂⁺Fe₃⁺)O₄ spinels (e.g., Fe, Co, Ni).

and Curie Weiss temperatures, providing insights into their thermodynamic behavior. Using the full potential linearized augmented plane wave (FP-LAPW) method, it investigates electrical and magnetic structures of spinel chromite, revealing magnetic moments in MnCr₂S₄. Seebeck coefficient and electrical conductivity are also calculated. Advanced techniques like Monte Carlo, DFT+U, and FLAPW analyze magnetic characteristics of LiMn₁.₅Ni₀.₅O₄ and electronic/magnetic structures of Fe₃O₄. High-temperature series expansions calculate Néel temperature and critical exponents, while GFT determines thermal magnetization and susceptibility. The analysis exposes exchange interactions' effects on magnetic order and introduces asymmetric phases in ferrimagnetic spinel systems. This book serves as an invaluable resource for researchers, academics, and enthusiasts seeking a comprehensive understanding of magnetic properties and critical phenomena within diverse spinel materials.Principles of Free Electron Lasers

By Sankar Chatterjee. 2023
This book presents a groundbreaking hypothesis to answer one of the greatest scientific mysteries: How did life begin? Like a…
detective piecing together seemingly disparate bits of evidence, Dr. Sankar Chatterjee combines the most recent discoveries in cosmology, geology, chemistry, information systems, and biology, weaving a vast tapestry from the threads of current research. Dr. Chatterjee convincingly argues that the odyssey of life first began when the fundamental building blocks were brought to Earth by meteorites. These cosmic compounds concentrated and simmered like a soup in hydrothermal crater-caldrons. Through a system of subterranean vent networks, a biosynthetic-rich variety of organic compounds mixed and matched into a recipe of rich biomolecules guided by prebiotic information systems. Through symbiosis, these complex biopolymers gradually assemble into membrane-bound protocells. At each stage of this evolutionary progression, through natural selection, they refined with increasing stability and complexity, ultimately leading to the emergence of the first cells about four billion years ago. In this book, Dr. Chatterjee tells this story in rigorous detail in language that is both accessible and engaging.
