Scientists are increasingly finding themselves engaged in research problems that cross the traditional disciplinary lines of physics, chemistry, biology, materials science, and engineering. Because of its broad scope, statistical mechanics is an essential tool for students and more experienced researchers planning to become active in such an interdisciplinary research environment. Powerful computational methods that are based in statistical mechanics allow complex systems to be studied at an unprecedented level of detail. This book synthesizes the underlying theory of statistical mechanics with the computational techniques and algorithms used to solve real-world problems and provides readers with a solid foundation in topics that reflect the modern landscape of statistical mechanics. Topics covered include detailed reviews of classical and quantum mechanics, in-depth discussions of the equilibrium ensembles and the use of molecular dynamics and Monte Carlo to sample classical and quantum ensemble distributions, Feynman path integrals, classical and quantum linear-response theory, nonequilibrium molecular dynamics, the Langevin and generalized Langevin equations, critical phenomena, techniques for free energy calculations, machine learning models, and the use of these models in statistical mechanics applications. The book is structured such that the theoretical underpinnings of each topic are covered side by side with computational methods used for practical implementation of the theoretical concepts.

Kepler's essay, On the Six-Cornered Snowflake, provides the first published evidence of the ideas of regular arrangements and close-packing which have proved fundamental to crystallography. In it, Kepler ponders on the problem of why snowflakes are hexagonal, two centuries before the first successful steps were taken towards its solution. The purpose of this volume is to display the historical, literary, scientific, and philosophical treasures of Kepler's essay. The book includes the modernized text of the 1611 Latin edition, with an English translation by Colin Hardie on the opposite pages. The text is accompanied by an introduction giving details of the history of the work, and two essays; Professor B. J. Mason's discussion of the scientific meaning and validity of Kepler's arguments and their relation to the history of crystallography and of space filling, and L. L. Whyte's examination of Kepler's facultas formatrix in relation to the history of philosophical and scientific ideas on the genesis of forms.

Reaction Rate Theory and Rare Events bridges the historical gap between these subjects because the increasingly multidisciplinary nature of scientific research often requires an understanding of both reaction rate theory and the theory of other rare events. The book discusses collision theory, transition state theory, RRKM theory, catalysis, diffusion limited kinetics, mean first passage times, Kramers theory, Grote-Hynes theory, transition path theory, non-adiabatic reactions, electron transfer, and topics from reaction network analysis. It is an essential reference for students, professors and scientists who use reaction rate theory or the theory of rare events.
In addition, the book discusses transition state search algorithms, tunneling corrections, transmission coefficients, microkinetic models, kinetic Monte Carlo, transition path sampling, and importance sampling methods. The unified treatment in this book explains why chemical reactions and other rare events, while having many common theoretical foundations, often require very different computational modeling strategies.
Offers an integrated approach to all simulation theories and reaction network analysis, a unique approach not found elsewhere Gives algorithms in pseudocode for using molecular simulation and computational chemistry methods in studies of rare events Uses graphics and explicit examples to explain concepts Includes problem sets developed and tested in a course range from pen-and-paper theoretical problems, to computational exercises

När det gäller sömn och vakenhet måste vi överväga vad de är: om de är unika för själen eller kroppen, eller gemensamma för båda … dessutom av vilken orsak uppkommer de som egenskaper hos djur … – Aristoteles, Om sömn och sömnlöshet, 350 före vår tideräkning
I det antika Grekland var sömnen och drömmarnas värld centrala i myterna och filosofin. Vår förundran över sömnen lever kvar och har genom historien lett till otaliga experiment och teorier. Människan har gått från att använda sig av vad hon hittar i naturen till att i laboratorier forska fram det perfekta pillret för att antingen söva oss eller hålla oss vakna. Vad sägs om dårrepe eller vallmo till kvällen och en kopp kaffe eller kokablad för att piggna till? Gemensamt för alla dessa substanster är att de har påverkat vårt kemiska förhållande till natten.
I Nattens gudar leder Ulf Ellervik oss genom kulturhistorien och vetenskapen för att finna svar på sömnens och vakenhetens gåtor.

One hundred years ago, Marie Curie discovered radioactivity, for which she won the Nobel Prize in physics. In 1911 she won an unprecedented second Nobel Prize, this time in chemistry, for isolating new radioactive elements. Despite these achievements, or perhaps because of her fame, she has remained a saintly, unapproachable genius. From family documents and a private journal only recently made available, Susan Quinn at last tells the full human story. From the stubborn sixteen-year-old studying science at night while working as a governess, to her romance and scientific partnership with Pierre Curie,an extraordinary marriage of equals,we feel her defeats as well as her successes: her rejection by the French Academy, her unbearable grief at Pierre's untimely and gruesome death, and her retreat into a love affair with a married fellow scientist, causing a scandal which almost cost her the second Nobel Prize. In Susan Quinn's fully dimensional portrait, we come at last to know this complicated, passionate, brilliant woman.

Författaren till boken Organisk-kemisk nomenklatur - En introduktion till det kemiska språket vänder sig i sin framställning främst till alla studerande och yrkesverksamma som behöver en handbok i grundläggande organisk-kemisk nomenklatur. Det genomgående temat i boken är IUPAC:s substitutiva nomenklatur, men även mer speciella områden, t.ex. ringsystem och isotopiskt modifierade föreningar, behandlas. Organisk-kemisk nomenklatur är främst avsedd som vägledning vid översättning av kemiska namn till strukturformler, men behandlar också några typexempel på namnkonstruktion. Många exempel på ringnomenklatur har hämtats från läkemedelsområdet, och behandlingen av aminosyrenomenklatur är mer utförlig än tidigare.

Nonlinear Solid Mechanics a Continuum Approach for Engineering Gerhard A. Holzapfel Graz University of Technology, Austria With a modern, comprehensive approach directed towards computational mechanics, this book covers a unique combination of subjects at present unavailable in any other text. It includes vital information on 'variational principles' constituting the cornerstone of the finite element method. In fact this is the only method by which Nonlinear Solid Mechanics is utilized in engineering practice. The book opens with a fundamental chapter on vectors and tensors. The following chapters are based on nonlinear continuum mechanics - an inevitable prerequisite for computational mechanicians. In addition, continuum field theory (applied to a representative sample of hyperelastic materials currently used in nonlinear computations such as incompressible and compressible materials) is presented, as are transversely isotropic materials, composite materials, viscoelastic materials and hyperelastic materials with isotropic damage. Another central chapter is devoted to the thermodynamics of materials, covering both finite thermoelasticity and finite thermoviscoelasticity. Also included are:* an up-to-date list of almost 300 references and a comprehensive index* useful examples and exercises for the student* selected topics of statistical and continuum thermodynamics.Furthermore, the principle of virtual work (in both the material and spatial descriptions) is compared with two and three-field variational principles particularly designed to capture kinematic constraints such as incompressibility. All of the features combined result in an essential text for final year undergraduates, postgraduates and researchers in mechanical, civil and aerospace engineering and applied maths and physics.

The ultimate eye-opening journey through time and space, A Short History of Nearly Everything is the biggest-selling popular science book of the 21st century and has sold over 2 million copies.'Possibly the best scientific primer ever published.' Economist'Truly impressive...It's hard to imagine a better rough guide to science.' Guardian'A travelogue of science, with a witty, engaging, and well-informed guide' The TimesBill Bryson describes himself as a reluctant traveller, but even when he stays safely at home he can't contain his curiosity about the world around him. A Short History of Nearly Everything is his quest to understand everything that has happened from the Big Bang to the rise of civilization - how we got from there, being nothing at all, to here, being us.Bill Bryson's challenge is to take subjects that normally bore the pants off most of us, like geology, chemistry and particle physics, and see if there isn't some way to render them comprehensible to people who have never thought they could be interested in science. As a result, A Short History of Nearly Everything reveals the world in a way most of us have never seen it before.

As a scientist, you are a professional writer: your career is built on successful proposals and papers. Success isn't defined by getting papers into print, but by getting them into the reader's consciousness. Writing Science is built upon the idea that successful science writing tells a story. It uses that insight to discuss how to write more effectively. Integrating lessons from other genres of writing with those from the author's years of experience as author, reviewer, and editor, the book shows scientists and students how to present their research in a way that is clear and that will maximize reader comprehension.The book takes an integrated approach, using the principles of story structure to discuss every aspect of successful science writing, from the overall structure of a paper or proposal to individual sections, paragraphs, sentences, and words. It begins by building core arguments, analyzing why some stories are engaging and memorable while others are quickly forgotten, and proceeds to the elements of story structure, showing how the structures scientists and researchers use in papers and proposals fit into classical models. The book targets the internal structure of a paper, explaining how to write clear and professional sections, paragraphs, and sentences in a way that is clear and compelling. The ideas within a paper should flow seamlessly, drawing readers along. The final section of the book deals with special challenges, such as how to discuss research limitations and how to write for the public. Writing Science is a much-needed guide to succeeding in modern science. Its insights and strategies will equip science students, scientists, and professionals across a wide range of scientific and technical fields with the tools needed to communicate effectively.

Boken beskriver och förklarar organiska molekylers otroliga mångfald, deras strukturer och egenskaper, och hur de kan delta i kemiska reaktioner och därmed användas i samhället. Den organiska kemin är fundamental för många vetenskapliga områden, den lägger till exempel grunden för livsprocesserna, och kunskaper i ämnet öppnar många dörrar.I denna tredje upplaga av boken har materialet till stor del om arbetats. Dels delas materialet tydligare in i en deskriptiv del som beskriver fysikalisk-organiska begrepp och olika föreningsklasser, och en mer mekanistisk del som beskriver organiska föreningars reaktioner och hur man kan utnyttja dem. Mellan de två blocken ges en introduktion till modeller för elektronfördelning och till slut ytterligare två deskriptiva kapitel om organisk analys och biologiska makromolekyler. Ett helt nyskrivet kapitel beskriver den metall organiska kemin som har utvecklats snabbt under de senaste åren, och den tredje upplagan har även utökats med ett avsnitt om grön kemi.

This book reveals glimpses of how the quantum physics of atoms and molecules influences, and even controls, the way our cells function and how we and our fellow animals interact with our environment. Simply put, how birds fly and why grass grows.Certainly, biochemistry and molecular biology are the foundations for the biology of living cells, but there is more—quantum coherence and entanglement influencing the functioning of proteins and enzymes, and strictly speaking, without the quantum phenomena we wouldn’t even be here.In the end, however, this book is based on the solid ground of science, presenting the many fascinating phenomena of how quantum physics makes life possible without any unwarranted mystification.
