The Human Genome Project (HGP) began in 1990 as an effort by researchers from around the world to map and sequence the human genome - the totality of human DNA - as well as the genomes of important experimental organisms, like yeast, the nematode worm, and mouse. In 2000, the collaborators in the HGP announced the completion of a draft revealing the sequence of 90% of human DNA. In February 2001, the initial analysis of the genome sequence was published in the scientific literature. To mark this occasion, the Human Genome Project has released a free, multimedia educational kit, The Human Genome Project: Exploring our Molecular Selves. This web page contains the online version of the education kit's CD-ROM.

The Living Edens, an inspiring natural history series, opens magical vistas to viewers through the expertise of world-acclaimed natural history filmmakers in a series of programs throughout the year. Its state-of-the-art cinematography creates an intimate sense of place and captures a world of wonder, transporting viewers to isolated, undisturbed corners of the globe so pure they remind us of how the ancient world once was.

The nitrogen cycle represents one of the most important nutrient cycles found in terrestrial ecosystems (Figure 9s-1). Nitrogen is used by living organisms to produce a number of complex organic molecules like amino acids, proteins, and nucleic acids. The store of nitrogen found in the atmosphere, where it exists as a gas (mainly N2), plays an important role for life.

Welcome to the Nucleus, a website designed for physics and astronomy undergrads. There are all sorts of resources for research and learnding, plus cool links and discussion forums for talking with fellow students. Topics include: intro physics, modern physics, classical mechanics, electricity and magnetism, quantum mechanics and general relativity.

A multimedia tour covering the discovery of the ozone hole, recent ozone loss over Antarctica, the science of the ozone hole, and the latest ozone hole research at the University of Cambridge.

The Particle Data Group of Lawrence Berkeley National Laboratory presents an award-winning interactive tour of quarks, neutrinos, antimatter, extra dimensions, dark matter, accelerators and particle detectors.

The Physical Environment is one of the first, totally online physical geography learning environments. The Physical Environment combines text, images, audio and video programs to deliver the subject matter content. A multimedia online environment requires that you interact with the content in new and different ways.The potential of the World Wide Web to bring remote places to our desktops, and the ability to interlink bits of information, breathes life into physical geography. No longer is one tied to a static image in a book, or the graphics available on a CD-ROM. The interconnectivity of the Web engages us in new ways of learning. Hyperlinked resources lets us stay abreast of the latest developments. The reader can explore in greater depth than ever before the physical world from their desktop.

How does a rainbow form? Is levitation possible? Do time machines exist? What does 'quantum' mean? This site publishes a free physics textbook that tells the story of how it became possible, after 2500 years of exploration, to answer such questions. The text explores the limits of time and space, and the wonders that can be discovered there. Written in English, its over 1200 pages are provided for students, teachers, and for anybody who is interested in the precise description of nature. For each field of physics, the latest research results, the most interesting physical puzzles and the most telling physical curiosities are presented. Over 680 solved challenges and 510 figures, photographs and tables are included.

Air pollution can make you sick. Air pollution can damage the environment. Air pollution can damage property. Air pollution can cause haze, reducing visibility in national parks and sometime interfering with aviation. The Clean Air Act will improve air quality in the United States, a good thing for your health, your property and the environment. The 1990 Clean Air Act is lengthy--about 800 pages--because it tackles many difficult and complicated air pollution problems. We have prepared this summary of the 1990 version of the Clean Air Act because we think everyone should understand what is in the law and how it may affect them.

The Probability Web is a collection of probability resources on the World Wide Web (WWW). The pages are designed to be especially helpful to researchers, teachers, and people in the probability community.

Basic genetics, genome draft sequence, and post-genome science.

Our goal is to create an educational learning experience in the field of science while maximizing the fun, excitement, and innovation all through the internet. We have divided our explorer into four major facets, Math, Biology, Chemistry, and Physics. A click through these topics will reveal innovative activities that'll help introduce and involve you in fun key concepts. In addition, we have provided an Interact! section so that users from all over the world may be able to talk and collaborate with each other on the science topic.

This site shows that some ancient questions about "things going wrong" in our lives have surprisingly simple answers in modern basic chemistry. We'll talk mainly about down-to-earth things -- common solid objects of wood, metal, and bone, not about complex computer chips or programs going wrong. Written by Frank L. Lambert, Professor Emeritus, Occidental College. The Encyclopedia Britannica has not only given this site an Internet Guide Award but is allowing a direct search link to its great encyclopedia. Thus, in addition to going on to much more complex aspects of the second law after reading this site, you can also access the entire span of knowledge in the Britannica -- all of science, the humanities, and practical matters in the world.

Physicists have developed a theory called The Standard Model that explains what the world is and what holds it together. It is a simple and comprehensive theory that explains all the hundreds of particles and complex interactions with only: 6 quarks; 6 leptons (the best-known lepton is the electron); and force carrier particles, like the photon. All the known matter particles are composites of quarks and leptons, and they interact by exchanging force carrier particles.
