We review the current standard model for the evolution of the Universe from an early inflationary epoch to the complex hierarchy of structure seen today. We summarize and provide key references for the following topics: observations of the expanding Universe; the hot early Universe and nucleosynthesis; theory and observations of the cosmic microwave background; Big Bang cosmology; inflation; dark matter and dark energy; theory of structure formation; the cold dark matter model; galaxy formation; cosmological simulations; observations of galaxies, clusters, and quasars; statistical measures of large-scale structure; and measurement of cosmological parameters. We conclude with discussion of some open questions in cosmology. This review is designed to provide a graduate student or other new worker in the field an introduction to the cosmological literature.

How did our sun come into being? What keeps it hot and luminous, and what will be its ultimate fate? This fascinating and informative book offers answers to some of nature's most exciting and difficult questions. George Gamow, renowned physicist and author of the best-seller One Two Three . . . Infinity, outlines the fundamental discoveries and theories of modern physics that illuminate the evolution of our world. One of the founders of Big Bang theory, Gamow traces the anatomy of matter in terms of modern physics. In language that's both scientifically accurate and simple enough for nonspecialists, he explains the development of atomic theory from its earliest articulation by Democritus in 375 B.C. through studies of nuclear reactions and radioactive decay. Along the way, Gamow discusses the formation of the stars and planets, the nature of red and white dwarfs, the dimensions of our stellar system, the infinity of space, and other fascinating subjects.

This is a book about astronomy, the study of the Sun, Moon, planets, stars, galaxies and other objects found in the sky. It is not a book about astronauts, rockets, and space travel, although these interesting topics are occasionally mentioned. Nor is it a book about astrology and horoscopes, written to collect money for its entertainment value. This book is a crash course in basic astronomy, written for those who have never found the opportunity to learn any astronomy before now – especially elementary and middle school teachers, and parents of children in these grades. The book is intended as a source of information on the basic astronomical topics that are part of a strong science curriculum. Astronomy is the perfect introductory science: it is interesting, it is fun, and it doesn't get your hands dirty. Why should anyone study astronomy? What practical use is it to us? Many people realize that astronomy is the basis for such activities as time-keeping, navigation, and picking out constellations while camping under the stars. But astronomy is important for another reason: it fascinates people – even those who know very little about it. Children especially, are eager to learn about planets and stars, worlds much different from their own, which give their imaginations a flying start. They are amazed by the huge numbers, distances, and sizes that are encountered with every new topic. And they like being able to make predictions of moon phases, eclipses, and other events in the sky – predictions that can then be verified by observations. In a school setting, astronomy is a natural cross-curricular topic; it develops and exercises mathematical and scientific thinking processes and stimulates the imagination. Integrating curriculum strands is easy with astronomy, as it provides topics for learning activities in language arts, social studies, math, and science. The book presents a simplified view of astronomy. Equations have been minimized, numbers have been rounded, and the black-and-white diagrams can be easily reproduced on a chalkboard – which is where most of them originated. (Nice color images of planets, moons, and such do not appear here, as they can easily be found on the web.) Terms are explained in the chapters, as needed, and also collected in the glossary at the end of the book. Most of the topics are reasonably tame: they include sunrise and sunset, shadows and seasons, moon phases, planets, and such. Discussions of black holes, pulsars, quasars, supernovae, and other exotic objects are a bit premature at this level and will be omitted. Throughout most of the book we will stay fairly close to home; let us define what that means.

Optics and interferometry with matter waves is the art of coherently manipulating the translational motion of particles like neutrons, atoms and molecules. Coherent atom optics is an extension of techniques that were developed for manipulating internal quantum states. Applying these ideas to translational motion required the development of techniques to localize atoms and transfer population coherently between distant localities. In this view position and momentum are (continuouse) quantum mechanical degree of freedom analogous to discrete internal quantum states. In our contribution we start with an introduction into matter-wave optics in section 1, discuss coherent atom optics and atom interferometry techniques for molecular beams in section 2 and for trapped atoms in section 3. In section 4 we then describe tools and experiments that allow us to probe the evolution of quantum states of many-body systems by atom interference.

The GNU Astronomy Utilities (Gnuastro) is an official GNU package consisting of separate programs for the manipulation and analysis of astronomical data. All the various utilities share the same basic command line user interface for the comfort of both the users and developers. GNU Astronomy Utilities is written to comply fully with the GNU coding standards so it integrates finely with the GNU/Linux operating system. This also enables astronomers to expect a fully familiar experience in the source code, building, installing and command line user interaction that they have seen in all the other GNU software that they use. For users who are new to the GNU/Linux environment, unless otherwise specified most of the topics in chapters 2 and 3 are common to all GNU software, for example installation, managing command line options or getting help. So if you are new to this environment, we encourage you to go through these chapters carefully. They can be a starting point from which you can continue to learn more from each program’s own manual and fully enjoy this wonderful environment.

Bayes’ Rule is a simple way of calculating conditional probabilities. Although a great deal has been written about the relevance of Bayes’ Rule in clinical settings, it is difficult to find a single article that is both mathematically comprehensive and easily accessible to students and professionals with clinical backgrounds. This article tries to fill that void, by laying out the nature and implications of Bayes’ Rule in a way that requires little or no background in probability theory. It builds on Meehl & Rosen’s classic (1955) paper, Antecedent probability and the efficiency of psychometric signs, patterns, or cutting scores, by laying out algebraic proofs that they simply allude to, and by providing extremely simple and intuitively accessible examples of the concepts that they simply assumed their reader understood.

This thesis aimes to experience with electronics, Arduino, MEMS sensors and 3D graphics to prototype novel human computer interaction approaches. As a computer scientist, I started this work with only a very limited electronics knowledge, just some memories from the high school days. In a period of 9 months, I progressively improved my electronics knowledge till the designing of quite complex printed circuit boards which have been used intensively in the human computer device prototyping. The Arduino prototyping platform has been used during this project. During my university background, we had a very limited education on low level programming and never had the possibility to program a microcontroller. During this project, I gradually became expert in Arduino functions and programming features. I’ve also experienced also with MEMS sensors, mainly accelerometers, gyroscopes and magnetometers used for orientation sensing. I also had to study and understand progressively complex orientation sensing algorithms which fuse the data coming from the sensors to implement robust attitude and heading sensing.

This paper is an introduction to Arduino programming for students who learned C on "Scientific Programming" by L.M. Barone, E. Marinari, G. Organtini and F. Ricci–Tersenghi, edited by World Scientific (or its italian counterpart "Programmazione Scientifica" edited by Pearson). "Scientific Programming" is an innovative textbook on computer programming thought for science students, who does not care about writing Hello World! on a screen, but are interested in using a computer as a tool to do science. Chapter 0 of "Scientific Programming" is about how computing and programming is important for a scientist. Chapter 1 is about information representation (there is no need for a Chapter uno here, since information is represented exactly in the same way on Arduino boards).
