"OPTICAL CHIPS AND CIRCUITS
Technological and theoretical innovations ranging from ranging from DNA computing to optical circuitry hold the potential to revolutionize computing [1:1363]. This paper provides an overview of developments in optical circuitry as these developments apply to computer technology.
In search of new computational power, some researchers are attempting to use light as an information carrier [5:245]. Pulses of light are "the fastest messengers in nature," and the light pulses "pass through one another without effect. That should allow any number of activities to take place simultaneously in an optical circuit" [1:1363].
To construct the elements of an optical circuit, some optics researchers are developing light guides that carry photons around ..."

"INTRODUCTION
The weather stands as one of the phenomena of the natural world that has a great effect on human activity but which human beings seem to be incapable of affecting, or even predicting with any accuracy. In this age of satellites, space travel, and computer simulations, though, we learn more and more about how the weather is formed and about different natural forces related to the weather either as cause or effect. Among the forces being studied today for the effect they have on weather conditions are the jet stream high above and the condition known as El Nino found in the Pacific ocean. The two in concert have a profound effect on the weather in California and throughout the Pacific region, with other effects extending far beyond that immediate area. El Nino has been blamed both for massive rains and drought ..."

"The Physics of Color Television
Most people who claim they do not understand physics, or who wonder if physics is important to learn about, do not realize that they probably spend two or more hours a day staring at complex multiple physics in action -- their color television sets (Dasgupta, 1994, 62). There they see in operation quantum physics (QP), molecular physics (MP), biophysics (BP), electrophysics (EP), spectralphysics (SP) and astrophysics (AP) -- to name just the more obvious (Basalla, 1988, 62). This analysis is a survey of how each of these branches of physics combine to create the medium of color television. To save space, the abbreviations of the physics fields will follow each application."

From the Paper
"Instrumentally produced images greatly extend the range of human vision. Consequently, numerous technologies have been developed to create them. Perhaps one of the most useful of these consists of ultrasound. Three-dimensional reconstructions of ultrasound images make them easier to understand. Thus, in recent years, several three-dimensional ultrasonographic systems have been applied to various uses. Perhaps, at some time in the future, such systems will not only display information, but interpret it as well.
The anatomic structures and physiologic processes responsible for vision provide humans with an extremely effective mechanism for gathering information. This system can be substantially enhanced through the use of instruments (7:9-29)."

"Tidal energy has been used by humans for hundreds of years. In the modern era, the power is utilized for the production of electricity. The technologies involved are both proven and effective. However, with the exception of a tidal power plant at La Rance, France, the energy resource remains largely undeveloped. This may be in part because of the relatively high cost of the electricity produced. Only in appropriate circumstances will tidal power ever utilize its potential as both a dependable and enduring power source.
Tidal surges are caused by complex interactions between the gravitational fields of the sun and the moon. These phenomena occur in cycles of varying length. For the most part, the earth's oceans bulge along an axis which is approximately in line ... "

"Before about the last quarter of the eighteenth century, electricity essentially did not exist as a comprehensible phenomenon. The effects of lightning were of course universally known, but no remotely accurate guesses had been made as to its causes. The phenomenon of static electricity was also known--the word electric and its variations comes from the Greek word elektron (in Latin, electrum), or amber, which produces static electricity when rubbed with a cloth (Shilling, 1948, p. 5). (confusing, the term was also used for an alloy of gold and silver, perhaps of similar color.) Experimentation with static electricity began in sixteenth-century Italy; Jerome Cardan, about 1550, first distinguished electrical from magnetic phenomena. The relationship between the two continued to be acknowledged; Gilbert, in 1600, ... "

From the Paper
" Many people have concluded that nuclear power is fundamentally evil (Morgan 7). Those who oppose nuclear power do so because, at least in a rough qualitative way, they have balanced the risks and benefits as they understand them and have concluded that no amount of readjustment in the organizations that manage the technology or in the nature and balance of the risks and benefits it brings will make nuclear power acceptable. Other people still view this issue as a balance of risks, costs, and benefits. Proponents of nuclear power argue that, with much re-education and some re-examining of current organizations and technology, the public can be persuaded to welcome back nuclear power (Morgan 7).
Although nuclear power continues to play an active role in the energy planning of other nations, the U.S. nuclear power..."

From the Paper
" By the last few decades of the nineteenth century, theoretical physics was entering a state of crisis.. This crisis, which reached its culmination about the turn of the century, was due to several factors. New discoveries, some quite accidental (such as that of X-rays) made physicists aware of previously unimagined form of radiant energy..
In addition, the development of precise means of measurements allowed experimental confirmation to be sought even for extremely subtle effects, which previously would have remained in the domain of theory alone.. For example, the luminiferous ether, through which light was supposed to move, was widely assumed to exist by nineteenth century physicists. Once its effects became measurable, experimentalists sought to identify them--and failed to find them, triggering a crisis.."

"Nuclear Energy in Italy
Following the nuclear accident at Chernobyl, an Italian referendum held in November of 1987 showed widespread opposition to all nuclear development.. In response to this poll, Italy's government came out with a new National Energy Plan (PEN) in August 1988.. The plan placed a 5.year moratorium on the construction of new nuclear plants and called for research into newer, safer designs that would one day allow nuclear power to return.. Since PEN went into effect, nuclear energy technologies have progressed considerably. These advances, as well as other factors, may soon cause Italy to reevaluate its nuclear energy policy.
The public poll of 1987 rejected an array of propositions that either favored nuclear power or facilitated the siting of..."

"The Confocal Microscope
Invention of the first microscope occurred about 1600 A.D. (3:39). As technology advanced, by 1887 improvements in resolution enabled John Buist to observe the small pox virus (3:40). Then, throughout the 20th century, progress in the field of microscopy accelerated (3:40). Ernst Ruska's invention of the electron microscope around 1930 increased resolutions by orders of magnitude (3:40). This was quickly followed by the development of phase contrast, differential interference contrast, and fluorescence microscopy techniques (11:183). It was the widespread use of fluorescent probes..and the background glare they produced..which eventually led to the development of the confocal microscope (3:40).
The first confocal microscope was invented by Minsky in 1955..."

"Nuclear Energy in Japan
More than any other country, Japan has staked its industrial future on nuclear power.. Its 40 commercial reactors currently supply about 26% of Japan's electricity.. In addition, by the year 2010, the Japanese government plans to double that number to about 80 in order to supply 43% of the country's electricity needs.. Since Japan has virtually no domestic supplies of coal or oil, nuclear power is its way of achieving energy independence..
In 1991 alone, the government allocated nearly 60% of its Science and Technology Agency's budget, or 317.3 billion yen, to nuclear research and development.. Its long.term policy involves the commercial use of plutonium in fast.breeder reactors and light.water reactors, as well as vigorous research on fusion."

"This research examines the global strategies of the American petroleum industry. The findings of this research are presented in four major areas of interest: production and consumption comparisons for the United States and other global regions; global configuration; global coordination; competition strategy; and industry structure.
The contemporary history of the United States has been and continues to be characterized by a dependency on foreign sources of energy--primarily on crude oil (Ashton, 1992, p. 82).
Overall, the United States produces energy in an amount equivalent to 88.9 percent of its total energy consumption
(Energy Information Administration, 1992, pp. 126-127).
Aggregate measures, however, do not reflect the mismatch between the country's energy production mix and the energy consumption ..."

From the Paper
"Historically, wind energy conversion systems can be considered as one of man's earliest machines. Windmills, according to documentation, were used in Persia as early as 644 A.D. to grind grain (5:9). Mechanically, the Persian windmill was a development of the watermill--an earlier machine used for turning grains into flour--and it looked a little like one turned up on end. A vertical shaft was set in a square tower, with sails set at right angles to the shaft at its top end. The wind passed through slots in the tower on to the sails, allowing the shaft to turn, as well as any machinery set at the bottom end (2:13).
Traditionally, this principle travelled with the prisoners of Ghengis Khan to China, where horizontal mills with matting sails, but without the enclosing tower, were used to drive irrigation machinery. The Chinese discovered that if the ..."

"This study will argue that a grand unified theory which is truly "grand" and "unified" will cover, theoretically, both the "outer" and "inner" limits of the universe. As we shall see, the most seriously considered grand unified theories do indeed cover both inner and outer limits.
Einstein worked on a Unified Field Theory for the last twenty-five or so years of his life. As Barnett writes, "Today the outer limits of man's knowledge are defined by Relativity, the inner limits by Quantum Theory. Relativity has shaped all our concepts of space, time, gravitation, and the realities that are too remote and too vast to be perceived. The Quantum Theory has shaped all our concepts of the atom, the basic units of matter and energy, and the realities that are too elusive and too small to be perceived" (1:107)."

"Chemical Weathering on Mars
Recent high pressure experiments have provided insight on the chemical composition of Mars' mantle (11:2239). Such studies indicate that 15.7 percent of the planet is composed of metal..a large proportion of which is iron (11:2239). It is estimated that partial melting of this mantle produces an iron.rich basaltic magma which generally reaches the planet's surface via massive shield volcanos and fissure eruptions (5:90). The extrusion of this turbulent, low viscosity lava has resulted in thinly disseminated iron sulfide mineralization over large areas of Mars (5:90). In addition to these iron.rich flows, the red planet's surface is also characterized by large accumulations of basaltic ash (7:2237). These deposits..some of which are meters thick..have undergone variable degrees of weathering (10:24). It ..."

"Water has been used to generate power for thousands of years. The use of water to generate electricity is a relatively new phenomenon, but one which has gained in popularity since such power is renewable and often readily available. This research explores the use and production of hydropower in Canada, with a special emphasis on the James Bay construction project. Attention is given to hydropower itself, different types of hydropower projects, and the economic, environmental and social costs associated with large hydropower megaprojects.
Hydroelectric power comes about when water passes through a vertical distance (called a 'head'). "Run-of-the-river" techniques use the head from the increased flow from a gradually declining riverbed. Dams use falling water which..."

The steam engine was the culmination, not quite the product of the Industrial Revolution. ... described all the components and principles of a practical steam engine in 1690. Thomas Savery built a steam-driven pump in 1698. Thomas Newcomen developed this (1708-12) into a machine in which steam generated by heated water was condensed by a jet of cold water, and the alternation of atmospheric pressure drove a piston up and down; this "atmospheric engine, remained the standard until James Watt transformed it into a true steam engine in 1765.
Unlike most of the inventors of his time, Watt was a student .. , "
