  • The science of acoustics deals with the creation of sound, sound transmission through solids, and the effects of sound on both inert and living materials. As a mechanical effect, sound is essentially the passage of pressure fluctuations through matter as the result of vibrational forces acting on that medium. Sound possesses the attributes of wave phenomena, as do light and radio signals. But unlike its electromagnetic counterparts, sound cannot travel through a vacuum.

  • The steps needed to define a successful space science mission are numerous. The science drivers, the unique advantages this mission provides over past missions or earth-based experiments, and the payload that it includes are the key factors to guarantee its success. Finding the required information on such topics is not so straightforward, especially as they are usually outside the scope of undergraduate courses. The 2003 Canary Islands Winter School of Astrophysics aimed at providing a focused framework that helps fill this need.

  • In response to a request from the National Economic Council, the National Academy of Engineering (NAE) convened a workshop on 30 April 1999 to assess the potential value of federally sponsored prizes and contests in advancing science and technology in the public interest. A five-member steering committee1 was appointed by NAE President Wm. A. Wulf to organize the workshop and prepare a brief summary report to sponsors. Funding was provided by the National Science Foundation (NSF).

  • Digital electronics is one of the fundamental courses found in all electrical engineering and most science programs. The great variety of LabVIEW Boolean and numeric controls/indicators, together with the wealth of programming structures and functions, make LabVIEW an excellent tool to visualize and demonstrate many of the fundamental concepts of digital electronics. The inherent modularity of LabVIEW is exploited in the same way that complex digital integrated circuits are built from circuits of less complexity, which in turn are built from fundamental gates.

  • Polychlorinated biphenyls (PCBs) are a family of chemical compounds which do not exist in nature but which are manmade. Commercial mixtures are clear, pale yellow liquids manufactured by the replacement of hydrogen atoms on the biphenyl molecule by chlorine. The reaction is controlled according to the percentage replacement of hydrogen and results in a product which contain chlorobiphenyls with one or, more usually, several chlorine atoms attached to each molecule.

  • Since its first implementation by Lauterbur [1], Magnetic Resonance Imaging (MRI) has become an important noninvasive imaging modality. MRI has found a number of applications in the fields of biology, engineering, and material science. Because it provides unique contrast between soft tissues (which is generally superior to that of CT) and high spatial resolution, MRI has revolutionized diagnostic imaging in medical science. An important advantage of diagnostic MRI as compared to CT is that the former does not use ionizing radiation....

  • In the editors’ preface to the fourth edition it was noted that there was good news and there was bad news. It is the same for this, the fifth edition. One suspects that this will always be the case. The 2004 Nobel Prize for Peace has been awarded to Professor Dr. Wangari Maathai. Dr. Maathai’s award was based on her efforts on behalf of conservation and women’s rights. These efforts were made at great personal risk. In addition, the Kyoto Protocol has been ratified by the requisite number of countries.

  • Development planning is a contested terrain, particularly in sub-Saharan Africa. Historically, the approach to African development has been externally oriented. For the past four decades, the subcontinent has been negotiating its development with external partners. More often than not, this has meant that the process, instruments and outcomes of development have been determined by external partners, rather than by African societies and their leaders.

  • Forty years ago, Congress asked the National Academies Committee on Science, Engineering, and Public Policy (COSEPUP)—the only joint policy committee of the National Academy of Sciences, National Academy of Engineering, and Institute of Medicine—to look at the relationship between basic research and national goals. That request, from the House Committee on Science and Astronautics in 1964, resulted in the report Basic Research and National Goals.

  • The committee was tasked to determine the best instrumentation and procedures for measuring BFD (see Box S-1). To do this, it reviewed technical specifications, viewed demonstrations of the operation and use of current and prospective systems, and evaluated factors such as human handling variability, process transparency, and software variability judgment. The committee found that given the current clay variation, a measurement precision (standard deviation) of 0.5 mm is sufficient; instruments featuring greater precision add little practical value to the testing process.

  • What would science be without measurement, and what would social science be without social measurement? Social measurement belongs to the widely accepted and fruitful stream of the empirical-analytic approach. Statistics and research methodology play a central role, and it is difficult to ascertain precisely when it all started in the social sciences. An important subfield of social measurement is the quantification of human behavior—that is, using measurement instruments of which educational and psychological tests are the most prominent representatives.

  • According to classical physics the particle cannot be a wave, and the wave cannot be a particle. However, Einstein, while explaining the photoelectric effect (PEE), postulated that electromagnetic radiation has a dual wave-particle nature. He used the term photon to refer to the particle of electromagnetic radiation. He proposed a simple equation to relate the energy of the photon E to the frequency n and wavelength l of electromagnetic wave.
