  • Although much of its discovery process is descriptive and qualitative, chemistry is fundamentally a quantitative science. It serves a wide range of human needs, activities, and concerns. The mathematical sciences provide the language for quantitative science, and this language is growing in many directions as computational science in general continues its rapid expansion. A timely opportunity now exists to strengthen and increase the beneficial impacts of chemistry by enhancing the interaction between chemistry and the mathematical sciences.

  • At one time, computational chemistry techniques were used only by experts extremely experienced in using tools that were for the most part di½cult to understand and apply. Today, advances in software have produced programs that are easily used by any chemist. Along with new software comes new literature on the subject. There are now books that describe the fundamental principles of computational chemistry at almost any level of detail.

  • The advent of ever-more sophisticated methods of information retrieval is revolutionising the way chemists work. The possibility of accessing a database which, in a matter of seconds, is capable of providing hundreds of methods of carrying out a synthetic transformation means that the time in which a synthetic strategy can be planned is reduced enormously. A subtle, but no less profound effect of this completely new approach is in the way chemists handle the 'vocabulary' of their profession, a knowledge of possible chemical transformations.

  • Weather natural hazards, the environment and climate change are of concern to all of us. Especially, it is essential to understand how human activities might impact the nature. Hence, monitoring, research, and forecasting is of the outmost importance. Furthermore, climate change and pollution of the environment do not obey national borders; so, international collaboration on these issues is indeed extremely important.

  • Lichens have been used to study air pollution chemistry in national parks and forests since the 1980s (Figures 1 and 2). There have also been a few lichen studies on national wildlife refuges. Most of the studies have been floristic studies, reports of baseline concentrations of elements in lichen tissues and, occasionally, trends in these concentrations. Figure 1 shows park and refuge locations with tissue chemistry data. USGS Biological Resources Division maintains a web site listing lichens known from each of the national parks shown on the map (http://www.ies.wisc.

  • Science and engineering have dominated world events and world culture for at least 150 years. The blind and near blind have been made to see. The deaf and near deaf have been made to hear. The ill have been made well. The weak have been made strong. Radio, television and the internet have made the world seem smaller. And some of us have left the planet. Computers have played an essential role in all of these developments; they are now ubiquitous. These miraculous events happened by design— not by accident. Individuals and teams set out to accomplish goals.

  • Discussion of nanotechnology can quickly become complex as a full analysis involves advanced chemistry, biology, physics, computer science, and engineering. The properties of nano-scale materials are governed by laws of quantum physics, causing materials to display properties and characteristics that would be considered by the laws of classic Newtonian physics. It is these intermolecular forces which cause nanotechnology to be both a vexing research problem, and yet have enormous potential.
