This book is the first synthesis of the practice and the philosophy of the scientific method. It offers scientists a deeper understanding of the underpinnings of the scientific method, thereby leading to more productive research and experimentation. It also provides a greater perspective on the rationality of the scientific approach and its role in society. Topics relevant to a variety of disciplines are treated, and clarifying figures, case studies, and chapter summaries enhance the pedagogy.

Science teachers come in many varieties, but they share a common goal: to nurture learners. Over the past decade, we have learned a great deal about how to do this effectively. Of all this new (and some not so new) knowledge, what strikes me as most important is that learning occurs best within a context. Still, as obvious as that may seem, it is relatively rare in our high school science classrooms. The problem, of course, is that it is not easy to create a learning experience with hands-on relevance to the science under discussion. Science teachers, in addition to not having the the time, for the most part do not have the expertise or readily available resources. The solution lies in finding ways to bring scientists into the teaching/learning equation. Scientists teamed with teachers and their students represent a very real and rich opportunity to involve students in real science as practiced. Imagine a research book that gives examples of honest, science-research experiences for science-oriented students. What's more, imagine a book that includes examples where students are collaborating with scientists from all over the world on research projects, in person or via the Internet. Internet Linksfor Science Education does just that. It explores the role of the Internet and technol ogy in working student-scientist partnerships.

This book explicates the optical controls of antiferromagnetic spins by intense terahertz (THz) electromagnetic waves. The book comprises two key components: (1) the experimental demonstration of the enhancement of a THz magnetic field using a split-ring resonator (SRR) and (2) the control of the direction of magnetization by using the enhanced THz magnetic field to break the symmetry of optically-induced phase transition. These make up the first step leading to future spintronics devices. In the beginning of the book, the author reviews the basics of the ultrafast laser and nonlinear optical techniques as well as the previously achieved experiments to control spin dynamics by THz magnetic fields. In this context, a new experimental protocol is described, in which electron spins in a ferromagnetic material are redirected at the unprecedented level in cooperation with the enhanced THz magnetic field. Subsequently, the author demonstrates that the THz magnetic field is significantly amplified as a nearfield around the SRR structured metamaterial, which is implemented by measuring spin precession in a solid. At the end, the author presents the key experiment in which the amplified THz magnetic nearfield is applied to the weak ferromagnet ErFeO3 along with the femtosecond near-infrared pulse, demonstrating the successful control of symmetry breaking of the spin system due to coherent control of the optically-induced spin reorientation phase transition pathways. The comprehensive introductory review in this book allows readers to overview state-of-the-art terahertz spectroscopic techniques. In addition, the skillful description of the experiments is highly informative for readers in ultrafast magnonics, ultrafast optics, terahertz technology and plasmonic science.

At this very moment the most ambitious scientific experiment of all time is beginning, and yet its precise aims are little understood by the general public. This book aims to provide an everyman's guide for understanding and following the discoveries that will take place within the next few years at the Large Hadron Collider project at CERN. The reader is invited to share an insider's view of the theory of particle physics, and is equipped to appreciate the scale of the intellectual revolution that is about to take place. The technological innovations required to build the LHC are among the most astonishing aspects of this scientific adventure, and they too are described here as part of the LHC story. The book culminates with an outline of the scientific aims and expectations at the LHC. Does the mysterious Higgs boson exist? Does space hide supersymmetry or extend into extra dimensions? How can colliding protons at the LHC unlock the secrets of the origin of our universe? These questions are all framed and then addressed by an expert in the field. While making no compromises in accuracy, this highly technical material is presented in a friendly, accessible style. The book's aim is not just to inform, but to give the reader the physicist's sense of awe and excitement, as we stand on the brink of a new era in understanding the world in which we all live.

The functional anatomy of human somatosensory cortex is of both scientific and clinical interest. Scientifically, it provides insights in information processing in the human brain. Clinically, it helps to avoid neurological deficits by sparing essential brain regions during neurosurgical procedures adjacent to central fissure. In the present study the functional organization of the human somatosensory cortex was investigated with electrophysiological techniques using a combined approach of cortical stimulations and somatosensory evoked responses on electrocorticography, scalp-EEG, and magnetoencephalography. The spatiotemporal structure of the evoked response was studiedwith biophysical modeling techniqueswhich allowed identification of the three-dimensional intracerebral location, time activity, and interaction of the neuronal sources activated following peripheral somatosensory stimulation. Furthermore, the somatotopic organization ofhand and lip somatosensory cortex was investigated. The relative value of invasive (cortical stimulations and electrocorticography) and non-invasive (scalp-EEGand magnetoencephalography) was assessed. The combined use ofscalp-EEG and magnetoencephalography was useful to increase non-invasive localization accuracy. I want to thank several people who significantly contributed in completion of the present work.

This book introduces the reader to the power of observation before, and sometimes instead of, experimental manipulation in the study of animal behavior. It starts with simple and easily accessible methods suitable for student projects, before going on to demonstrate the possibilities that now exist for far more sophisticated analyses of observational data. At a time when animal welfare considerations are attracting political as well as scientific debate, the potential for non-intrusive studies on animals is being increasingly recognized. Observation emerges as a valuable alternative approach, often yielding highly informative results in situations (such as on zoos, farms or for wild animals) where more invasive experimental techniques would be undesirable, unethical or just plain impossible. However, to justify its place alongside experimentation as a rigorous scientific method, observation needs to be just as disciplined and systematic and have just as much attention paid to project design in the way that observations are made and recorded.
Observing Animal Behaviour takes the reader through all these stages: from the initial observations, to the formulation of hypotheses, and their subsequent testing with further systematic observations. Although designed principally as a companion text for advanced undergraduate and students taking courses in animal behavior, this accessible text will be essential reading for anyone wanting to study animal behavior using observational methods rather than experimentation, and assumes no previous knowledge of animals, statistics or scientific method. It will be of particular relevance and use to those professional researchers and consultants inthe behavioral sciences who seek a compact but comprehensive introduction to the quantitative observation of animal behavior.

For most of the history of scientific endeavour, science has been recorded on paper. In this digital era, however, there is increasing pressure to abandon paper in favour of digital tools. Despite the benefits, there are barriers to the adoption of such tools, not least their usability. As the relentless development of technology changes the way we work, we need to ensure that the design of technology not only overcomes these barriers, but facilitates us as scientists and supports better practice within science. This book examines the importance of record-keeping in science, current record-keeping practices, and the role of technology for enabling the effective capture, reuse, sharing, and preservation of scientific data. Covering the essential areas of electronic laboratory notebooks (ELNs) and digital tools for recording scientific data, including an overview of the current data management technology available and the benefits and pitfalls of using these technologies, this book is a useful tool for those interested in implementing digital data solutions within their research groups or departments. This book also provides insight into important factors to consider in the design of digital tools such as ELNs for those interested in producing their own tools. Finally, it looks at the role of current technology and then considers how that technology might develop in the future to better support scientists in their work, and in capturing and sharing the scientific record.

Positive Pressure Ventilation (PPV) is a tactic that is used on fire grounds across the world everyday, both to improve tenability after the extinguishment of a fire and/or offensively during fire attack to improve firefighting conditions. PPV has proven that it can be a useful tool on the fire ground, but it can also kill or injure fire fighters and civilians if used improperly. Data from three full-scale experiments are compared with simulations completed with the computational fluid dynamic model Fire Dynamic Simulator (FDS). The full-scale experiments characterize a Positive Pressure Ventilation (PPV) fan in an open atmosphere, in a simple room geometry and in a room fire. All experiments qualify and quantify the comparison of the experimental results with the FDS results. A concluding scenario is modeled utilizing the calibration of the full-scale experiments to examine the effects of PPV on a fire in a two-story, colonial style house.

There can be no doubt that some ofthe most spectacular advances made in science over the past few decades have been in the isolation, analysis, and manipulation of nucleicacids. Thishas ledtoamuchgreaterunderstandingofmechanismsandprocesses across many fields of bioscience, such as biochemistry, microbiology, physiology, pharmacology, and the medical sciences to name a few. It has also led to the growth of the biotechnology industry, which seeks to develop and commercialize many ofthese important processes and methods. Much ofthis has come about because ofthe devel opment of numerous molecular biology and genetic manipulation techniques. The discovery of restriction enzymes and the development of cloning vectors in the early 1970sopenedthedoortowaysofisolatingandmanipulatingnucleic acidsthathadnever been thought possible. Gene probe labeling and hybridization were developed and refined toprovidepowerfulmethodsofanalysis. These-togetherwiththedevelopment of DNA sequencing methods, protein engineering techniques, and PeR-have all continued to contribute substantially to the understandingofbiological processes at the molecular level. Theprotocols for these importantmethods are the focus ofThe Nucleic AcidProtocols Handbook, whose aim is to provide a comprehensive set oftechniques in onevolume thatwill enable the isolation, analysis, and manipulationofnucleic acids to be readily undertaken. The NucleicAcidProtocols Handbook is divided into 10 parts; within each there are approximately 10chapters.
