  • In June 2006, seventeen scientists and educators selected by the National Academies, the Academy of Sciences of Iran, and the Académie des Sciences of France held a workshop at the estate of the Fondation des Treilles in Toutour, France, to discuss issues concerning the role of science in the development of modern societies. This location was an idyllic setting for relaxed conversations, while simplifying travel and visa arrangements for the participants.

  • New approaches to tailor-made cellulose/starch/lignin-synthetic polymer graft copolymers with precise control over molecular weight, degree of substitution, backbone-graft linkage, and the overall grafting process are being studied. Cross-linked graft copolymers with exactly defined polymer chain segments between crosslink points have been prepared. The graft copolymers exhibit a two-phase morphology and can function effectively as compatibilizers/interfacial agents to alloy cellulosic and lignocellulosic materials with synthetic polymers.

  • One who undertakes to represent certain results of scientific spiritual research of the kind recorded in this book, must above all things be prepared to find that this kind of investigation is at the present time almost universally regarded as impossible. For things are related in the following pages about which those who are today esteemed exact thinkers, assert that they will probably remain altogether indeterminable by human intelligence.

  • The bald and wrinkled head wobbled a bit on the thin neck, and his eyes were moist. Abravanel was a very old man. Looking at him, Neel realized for the first time just how old and close to death he was. It was a profoundly shocking thought. "Pardon me, sir," Neel broke in, "but is it possible? To lose a planet, I mean. If the readings are done correctly, and the k-factor equations worked to the tenth decimal place, then it's really just a matter of adjustment, making the indicated corrections. After all, Societics is an exact science—"...

  • The chess playing mind does not work like a machine. Selecting a move results from rather chaotic thought processes and is not the logical outcome of applying a rational method. The only problem with that, says International Master Willy Hendriks, is that most books and courses on improving at chess claim exactly the opposite. The dogma of the chess instruction establishment is that if you only take a good look at certain ‘characteristics’ of a position, then good moves will follow more or less automatically....

  • Perhaps nothing is so ingrained in our senses as the perpetual pulling of the earth on our surroundings. It’s always there, never changing. It’s been hugging solids, liquids and gases to the earth’s surface for over 4 billion years. Earth’s gravity is built into our descriptions of our world with words like up, down, and weight. Exactly what is weight? A weight is a force, nothing more. Your weight is the pull of earth’s gravity on your body. Likewise, the weight of your car is the force of the earth’s attraction for it. The greater the mass is, the...

  • Scientists still do not know exactly what causes the earth’s magnetic field. In the 16th century, it was believed that a mountain of magnetite (a magnetic mineral) was located at the North Pole and that this mountain caused the earth’s magnetic field. English physician William Gilbert was the first to propose, in 1600, that the earth itself was a massive magnet. Current theories hold that the earth’s magnetic field is created by currents within the liquid outer core of the earth, which is composed mostly of iron.

  • Graph theory can be said to have its beginning in 1736 when EULER considered the (general case of the) Königsberg bridge problem: Is there a walking route that crosses each of the seven bridges of Königsberg exactly once? (Solutio Problematis ad geometriam situs pertinentis, Commentarii Academiae Scientiarum Imperialis Petropolitanae 8 (1736), pp. 128-140.) It took 200 years before the first book on graph theory was written. This was done by KÖNIG in 1936. (“Theorie der endlichen und unendlichen Graphen”, Teubner, Leipzig, 1936. Translation in English, 1990.

  • I started my first photobiological research project almost exactly 50 years ago, in the spring of 1957. My scientific interest ever since has been focused on photobiology in its many aspects. Because I have been employed as a botanist, my own research has dealt with the photobiology of plants, but throughout this time I have been interested in other aspects, such as vision, the photobiology of skin, and bioluminescence. A first edition of the present book was published in 2002, but this second edition is much expanded and completely updated.

  • Creative accounting is nothing new. It has been a temptation and a problem from the moment that accounting principles were first used to report on business performance. There is an old joke about the accountant who is asked to add up two and two and who produces the response ‘What would you like the answer to be?’ It is an appropriate reminder that financial measurement is not an exact science. In fact this old joke provides a good starting point because it leads to a helpful working definition of creative accounting.

  • The exact relations between science and technology in particular have been debated by scientists, historians, and policymakers in the late 20th century, in part because the debate can inform the funding of basic and applied science. In the immediate wake of World War II, for example, in the United States it was widely considered that technology was simply "applied science" and that to fund basic science was to reap technological results in due time.

  • Planning Radio Networks In earlier chapters we discussed the characteristics of the radio propagation channel in some detail. We introduced methods for predicting the mean signal level within a small area in rural, suburban and urban environments and it became clear that this is a complicated process involving a knowledge of several factors, including the details of the terrain, the building clutter and the extent of foliage along the radio path.

  • Principles of Vaccine Use Route of Administration Microbes differ in their routes of infection, patterns of transmission, and predispositions for certain age groups. The route of vaccine administration (oral, intranasal, intradermal, transdermal, subcutaneous, or intramuscular) takes these factors into account in order to maximize protection and minimize adverse events. Vaccine development is more a pragmatic undertaking than an exact science, guided only in part by immunologic principles and shaped largely by the results of clinical trials.

  • When damage is identified with an index, it is difficult exactly match the index with the repair of damage. Therefore, the method is considered difficult to apply them to check the seismic risk based on definition of the changes in the process of damage and other details due to differences in design. To reach this goal, it is first necessary to calculate the design solution reflects the damage and the collapse of a structure under a uniform standard values ​​for different seismic forces....

  • We establish an exact relation between self-avoiding branched polymers in D + 2 continuum dimensions and the hard-core continuum gas at negative activity in D dimensions. We review conjectures and results on critical exponents for D + 2 = 2, 3, 4 and show that they are corollaries of our result. We explain the connection (first proposed by Parisi and Sourlas) between branched polymers in D + 2 dimensions and the Yang-Lee edge singularity in D dimensions.

  • We determine the order of magnitude of H(x, y, z), the number of integers n ≤ x having a divisor in (y, z], for all x, y and z. We also study Hr (x, y, z), the number of integers n ≤ x having exactly r divisors in (y, z]. When r = 1 we establish the order of magnitude of H1 (x, y, z) for all x, y, z satisfying z ≤ x1/2−ε . For every r ≥ 2, C 1 and ε 0, we determine the order of magnitude of Hr (x, y, z) uniformly...

  • Chemistry is the science which treats of the intra-atomic or the intra-molecular changes which material things undergo under various influences. Mental is defined as “of or appertaining to the mind, including intellect, feeling, and will, or the entire rational nature.” Science is knowledge gained and verified by exact observation and correct thinking. Mental chemistry is, therefore, the science which treats of the changes which material conditions undergo through the operations of the mind, verified by exact observation and correct thinking.
