In Society

One cannot navigate the modem world without regularly encountering the mechanical bond (Fig. 7). We typically take it for granted. So pervasive are interlocked structures in all things man-made, if we consciously acknowledged every mechanical bond we encountered, we would scarcely be able to accommodate any other mental processes Here, we simply point to fashion and technology as illustrative reminders of its omnipresence in society. 

We all wear the mechanical bond day in and day out those with body piercings even use it as a permanent decoration. This practice is not exclusive to Western society note the mechanically bound objects around the headdress, ears, mouth, and neck of the Mursi woman of southern Ethiopia in Fig. 7a, and the neck-extending 

The mechanical bond and technology have gone hand-in-hand since the advent of machinery. Indeed, many of the world s simplest and oldest machines, a wheel on an axle or a pulley (Fig. 7i), for example, are based on the mechanical bond. It has been especially important in transportation imagine trying to sail without knots and pulleys or drive without wheels It also appeared as early as 2,700 b.c. in the world s first calculator the abacus (Fig. If). And, just as we find it near the beginning of human history, most of us meet the mechanical bond near the beginning of our lives it is still among the most common features in children s toys, such as the timeless rattle or the bead maze in Fig. 7g. 

Perhaps by now it could go without saying that few modem machines would be capable of existing without some kind of mechanical bond, whether it is the washer around a screw or the disc in a hard drive. Various examples can be found in Fig. 7. Indeed, with every turn of a doorknob, draw of a curtain, or flip of a switch, the mechanical bond is at your service. Between fashion and technology, societies are irrevocably dependent on the mechanical bond. With mechanical bonds being such a necessary component in machinery, it is only fitting that they also represent a cornerstone of molecular machines (Sect. 4.5). 

All sorts of everyday objects have been reconstructed as molecules via template-directed synthesis of mechanical bonds, from switches and buttons to rotors and elevators. The likeness of MIMs to macroscopic objects and machines has done much to advance molecular nanotechnology and is, as we shall see, another important aspect of their beauty.

Approximately three-quarters of the elements in the Periodic Table are metals. The winning, refining, and fabrication of these metals for commercial use together represent the complex and diverse field of metallurgy. Metallurgy has played a vital role in society for thousands of years, yet it continues to advance and to have increasing importance in many areas of science and technology. 

Starr, 1969 approached this by investigating the "revealed preferences exhibited in society ls the result of trial and error. (Similar to the "efficient market theory" in the stock market.) Stan-conjectured that the risk of death from disease appears to determine a level of acceptable voluntary risk but that society requires a much lower level for involuntary risk. He noted that individuals seem to accept a much higher risk (by about 1000 times) if it is voluntary, e.g., sky-diving or mountain climbing, than if it is imposed, such as electric power or commercial air travel, by a correlating with the perceived benefit. From this study, a "law" of acceptable risk was found concluding that risk acceptability is proportional cube of the benefits. Figure 1.4.4-1 from Starr, 1972 shows these relationships. One aspect of revealed preferences is that these preferences do not necessarily remain constant (Starr et al., 1976). In Starr et al., 1976, it is shown that while nuclear power has the least risk of those activities compared, it also has the least perceived benefit. Clearly the public thinks that...

These can arise from changes in values of process workers (e.g., an increased focus on production rather than safety, because of a fear of reduced pay or job losses) due to larger changes in society (e.g., reduced job security because of an economic depression). 

The petroleum industry is a highly complex primary industry. Its function in society is to provide a reliable supply of liquid and gaseous hydrocarbon fuels and lubricants (and well as other related products) for both industrial and private customers. The industry is composed of two basic business elements 1 ) producing companies (often called operating companies) and 2) service companies. 

In the mid-nineteenth century, it was the custom for doctors to frequently prescribe morphine (first isolated from opium by Friedrich Serturner in 1806) and other opium preparations. Morphine did not have a major impact on medical practice until the invention of the hypodermic needle in 1840. Soldiers illness was recognized after the Civil War when more than 50,000 veterans became dependent on morphine as a result of treatment for combat injuries (Musto 1987). The public also had ready access to opium and purified drugs in grocery stores and pharmacies. Medicinal mixtures and nostrums, usually unlabelled as to contents, often contained opium or morphine. By the end of the century, many physicians had come to recognize that chronic use of morphine was a disorder (morphinism), although others in society...

The need of modern science to achieve a sustainable future development has been shown in many circumstances in society. Finding strategies less harmful to the environment has been a quest for research in several areas, such as pharmaceuticals, biotechnology, and food industries. With that purpose, the increase in research and development of more applications of xylan and its derivatives has shown the versatility of this biopolymer, thus helping the search for sustainable alternatives. 

In the early sixteenth century Reuchlin and Paracelsus had found in kabbalah a new justification for the practice of philosophy. Reuchlin had specifically sought to provide the Renaissance magus with an elite role in society through the practice of kabbalah. As a sign of... 

The first alkene polymer to be used in society was polyisoprene, a natural product extracted from the sap of rubber trees. See our Box for a description of the history of rubber. The monomer from which this polymer is constructed... 

Re-use, remanufacture and recycle. Focusing on re-use, remanufacture and recycling comes from a number of trends and drivers in society. Because of problems with waste disposal, many companies are trying to work towards a zero to landfill policy. As waste disposal costs rise, this trend will accelerate. At the same time, where raw materials are difficult or expensive to obtain, there is a real commercial incentive to recycle and reuse. Regulators also continue to push for the minimisation or elimination of the release of hazardous materials... 

Risk tolerability is a complex subject. Risk tolerance in society generally has changed over time and will continue to do so. Tolerance criteria may vary from company to company. Further, the reasons for the variations can differ from company to company. Many companies, in fact, have not developed explicit risk tolerance criteria.

Although electrochemistry has become increasingly important in society and in science the proportion of physical chemistry textbooks devoted to electrochemistry has declined both in extent and in quality (with notable exceptions, e.g. W. J. Moore s Physical Chemistry). 

Electronic equipment, including computers, printers, telephones, televisions, and stereos is ubiquitous in society today. These products often have a very limited lifetime due to the fast...
