The Oxford VR Group is developing a three-dimensional simulated laboratory for the teaching of chemistry. This laboratory will be modelled using virtual reality techniques and it will contain interactive multimedia experiments. Essentially, the student will be able to move around the lab in a web browser window and choose to take part in experiments that are distributed around this virtual lab. Each experiment will make use of the latest multimedia technology. This will include: digitized video and animations of the experiment being carried out; animated three-dimensional simulations of chemical objects (including molecules); interactive sections where the student will be required to work out what is going on and answer questions; and links to other useful internet sites relating to that topic.

Molecular Universe aims to provide accessible information on molecules and molecular systems. The site contains a range of graphical images relating to recent and not so recent developments in molecular and material sciences. The overall goal is to enhance understanding of the beauty and complexity of matter at the molecular level and to improve awareness of the central role of molecular processes in underpinning life itself and the operation of the world around us. The site includes explanatory text and links to relevant educational, academic and industry sites.

This book is for anyone with an interest in chaos, fractals, non-linear dynamics, or mathematics in general. It's a moderately heavy piece of work, requiring a bit of mathematical knowledge, but it is definitely not aimed at mathematicians. In the 1980s, strange new mathematical concepts burst forth from academic isolation to seize the attention of the public. Chaos. A fantastic notion. The study of the uncontainable, the unpredictable, the bizarre. Fractals. Curves and surfaces unlike anything ever seen in mathematics before. Surely, these topics are beyond the comprehension of all but the smartest, most educated, and most specialized geniuses. Wrong! Chaos, fractals, and the related topic of dimension are really not that difficult. One can devote an academic lifetime to them, of course, but the basic introduction presented in this book is no more difficult to understand than the straight line and the parabola.

Space weather. Space missions. Myths. Art, books, film. History and people. Geology. Life. Physics. Images and multimedia. Teacher resources. Our planet. Our solar system. Astronomy and the universe.

Utilizing over 800 scanned documents, photographs, audio clips and video excerpts, this website narrates the breathless details of the pursuit of the discovery of the double helix structure of DNA. Scattered throughout the project are images of a number of very important and extremely rare items, all of which are held within The Valley Library's Ava Helen and Linus Pauling Papers, and many of which have not been previously displayed. Also featured are two original documents hitherto unknown to scholars interested in this period. It is expected that this website will serve as a primary reference point for individuals interested in the history of DNA -- both researchers and lay people alike.

An animated primer on the basics of DNA, genes, and heredity. DNA from the Beginning is organized around key concepts. The science behind each concept is explained by: animation, image gallery, video interviews, problem, biographies, and links. Sections: Classical genetics, molecules of genetics, genetic organization and control.

Dive and Discover is an interactive distance learning Web site designed to immerse you in the excitement of discovery and exploration of the deep seafloor. Dive and Discover brings you right on board a series of research cruises to the Pacific and Indian Oceans, and gives you access to the latest oceanographic and deep submergence research as it happens! Be at the front line of scientific inquiry and join scientists - geologists, geophysicists, chemists and biologists - who are exploring the seafloor and making amazing deep-sea discoveries. Daily updates, photos, videos, and e-mail correspondence with scientists aboard research vessels allow you to follow the progress of the scientific mission and find out about life on the floating laboratories at sea.

Hands-on-CERN (HoC) is an educational project at the scientific frontier of physics. It is aimed at teachers and high school students studying natural sciences. The purpose of this project/course is to increase understanding of the most fundamental processes inside matter, and to explain modern research about particle collisions.

This website is an educational resource that describes the science behind volcanoes and volcanic processes. The site is sponsored by NASA under the auspices of Project ALERT (Augmented Learning Environment and Renewable Teaching). It is intended for the education of university students of geology and volcanology and teachers of earth science. Each section in the menu builds upon previous sections. For users who lack fundamental knowledge of volcanological principles and terms, it is best to proceed through the website in a progressive manner. More advanced users will find each section self-contained and can navigate through the website as their interest dictates.

At the start of the twentieth century, scientists believed that they understood the most fundamental principles of nature. Atoms were solid building blocks of nature; people trusted Newtonian laws of motion; most of the problems of physics seemed to be solved. However, starting with Einstein's theory of relativity which replaced Newtonian mechanics, scientists gradually realized that their knowledge was far from complete. Of particular interest was the growing field of quantum mechanics, which completely altered the fundamental precepts of physics.

Welcome to the World's Biomes Page! Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (Campbell). Biomes are classified in various ways. This page will group biomes into five major types: Aquatic, Deserts, Forests, Grasslands, and Tundra. These exhibits explore the ancestor/descendant relationships which connect all organisms, past and present. The importance of biomes cannot be overestimated. Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Thus, conservation and preservation of biomes should be a major concern to all. Hopefully, this page will increase your general knowledge of biomes. For further information, please consult the references page.

This is one of the most popular graduate courses within the CU DEES graduate curriculum. Useful for physical modeling of virtually any sort. Also available in PDF format. The purpose of this course is to develop the numerical and analytical skills required to formulate, execute and understand quantitative models of earth (and other) processes. These skills are becoming more and more necessary in quantitative earth science, however, there is, as yet, no formal mechanism for learning these techniques in a context that emphasizes real earth and environmental science problems. In addition to providing hands-on experience in modeling, this course will also attempt to de-mystify (or de-mythify) the general practice of forward modeling and provide enough insight to critically evaluate results of publiched models. This course is designed to complement G6908x Quantitative methods of data analysis by providing a fundamental set of data analysis by providing a fundamental set of quantitative tools that would benefit all earth scientists independent of discipline.
