Modern foundation

To make science more digestible and to provide a modern foundation, many schools and universities are already working to define and teach a canon of basic knowledge and fundamental principles which integrates the above components, stimulates curiosity, and thereby provides a basis for a rewarding career. [Pg.322]

Eiffel tower in Paris (Figure 1.1) is a good example of a new structure based on the principle of modern foundation engineering. Alexander Gustave Eilfel built the tower in 1889. Eiffel realized that a good foundation is vital for the tower in order not to suffer the same fate as the Leaning... [Pg.2]

Modern foundation engineering can be said to comprise various disciplines. This would include structural engineering, geotechnical engineering and construction engineering. [Pg.3]

Design methods for a modern foundation can generally be regarded as a mixture of rational and empirical techniques, and tend to vary between geographical regions, partly from instructor s influence and partly because there are few design absolutes . This is because we still do not fiilly understand the behavior of a foundation. The rational technique was developed from the principles of physics and science, and is useful to describe mechanisms we understand and are able to quantify. Conversely, the empirical technique is based on experimental data and local experience of physical mechanisms, of which we only have a limited understanding. [Pg.3]

Ostwald s Use of the Dropping Mercury Electrode. The modern foundation of the electromotive series is closely related to the effort of selecting a proper reference electrode for EMF measurements. At the turn of the century, W. Ostwald and W. Nernst did pioneering work in the field of reference electrodes, each approaching the problem from a different angle. [Pg.129]

The work on gas theory had many extensions. In 1865 Johann Josef Loschmidt used estimates of the mean free path to make the first generally accepted estimate of atomic diameters. In later papers Maxwell, Ludwig Boltzmann, and Josiah Willard Gibbs extended the rrratherrratics beyorrd gas theory to a new gerreralized science of statistical mechanics. Whenjoined to quantum mechanics, this became the foundation of much of modern theoretical con-derrsed matter physics. [Pg.782]

The foundation of modern hydraulics was established with Pascal s discovery that pressure in a fluid acts equally in all directions. This pressure acts at right angles to the containing surfaces. If some type of pressure gauge, with an exposed face, is placed beneath the surface of a liquid. Figure 40.4, at a specific depth and pointed in different directions, the pressure will read the same. Thus, we can say that pressure in a liquid is independent of direction. [Pg.587]

Thermodynamics is, in many ways, much like this modern science building. At the base of the science is a strong foundation. This foundation, which consists of the three laws, has withstood the probing and scrutiny of scientists for over a hundred and fifty years. It is still firm and secure and can be relied upon to support the many applications of the science. Relatively straightforward mathematical relationships based upon these laws tie together a myriad of applications in all branches of science and engineering. In this series, we will focus on chemical applications, but even with this limitation, the list is extensive. [Pg.680]

Why Do We Need to Know This Material All life on Earth is based on carbon so is the fuel we burn, our food, and the clothes we wear. Therefore, to understand a major part of the everyday world, we need to be familiar with the chemistry of this extraordinary element. Compounds of carbon and hydrogen are the foundation of the petrochemical industry petroleum products are used to generate electricity and to heat our homes. They are also used to make the flexible, strong polymeric and composite materials that make modern communication and transportation possible. [Pg.848]

This decade also saw the first major developments in molecular graphics. The first multiple-access computer was built at MIT (the so-called project MAC), which was a prototype for the development of modern computing. This device included a high-performance oscilloscope on which programs could draw vectors very rapidly and a closely coupled trackball with which the user could interact with the representation on the screen. Using this equipment, Levinthal and his team developed the first molecular graphics system, and his article in Scientific American [25] remains a classic in the field and laid the foundations for many of the features that characterize modern day molecular graphics systems. [Pg.286]

This book is an outgrowth of a suggestion made by Otto T. Benfey when he and Anthony S. Travis were associate editor and editor, respectively, of a series of books about the history of modern chemical sciences to be published jointly by the American Chemical Society and the Chemical Heritage Foundation. That series is, unhappily, no more, but their encouragement eventually became this book, and I am greatly indebted to them for their help. Ted Benfey, for example, read and critiqued every chapter of this book, a record shared only by George F. and Ruth Ann Bertsch. [Pg.256]

The preceding chapters have portrayed the consequences for science and for occult alchemy of their mutual interest in material transmutation. This chapter explores different cultural consequences of modem alchemy in relationship to monetary anxieties during the Depression Era. In particular, it narrates how the idea of modern alchemy intensified questioning of the gold standard and of the moral foundation of scientific aspiration. By the late 1920s and... [Pg.135]

The ability of transition-metal complexes to activate substrates such as alkenes and dihydrogen with respect to low-barrier bond rearrangements underlies a large number of important catalytic transformations, such as hydrogenation and hydroformy-lation of alkenes. However, activation alone is insufficient if it is indiscriminate. In this section we examine a particularly important class of alkene-polymerization catalysts that exhibit exquisite control of reaction stereoselectivity and regioselec-tivity as well as extraordinary catalytic power, the foundation for modern industries based on inexpensive tailored polymers. [Pg.509]

This graduate-level text presents the first comprehensive overview of modern chemical valency and bonding theory, written by internationally recognized experts in the held. The authors build on the foundation of Lewis- and Pauling-like localized structural and hybridization concepts to present a book that is directly based on current ab initio computational technology. [Pg.752]

Crude oil, also referred to as petroleum, is a resource that is drilled for throughout the world. When refined and processed, crude oil provides the energy resources we have come to depend on in modern society. Crude oil provides the foundation for many products including plastics and petrochemicals in addition to the fuel for our cars and heating oil for our homes. Each day, the United States uses billions of gallons of crude oil to support our daily lives. While many forms of transportation are used to move this product to marketplaces, pipelines remain the safest, most efficient and economical way to move this natural resource. [Pg.414]
