A great deal of today's modern technology exists due to the extensive use of the abundant chemical element, Silicon. California's Silicon Valley is where we find several of the world's most innovative and successful technology companies that touch all areas of human needs. Two of these companies, SunTech and Complete Genomics, are on the forefront of the innovative use of computing technology. Through their groundbreaking methods and designs they have harnessed the computing power of the Silicon Valley and applied it to creating more efficient and effective solar power generators as well as cost effective and highly accurate human genome mapping techniques.

Films the landforms and plant and animal life of Death Valley. Details how animals and plants have adapted to this extreme environment. Interviews biologist who are studying the endangered desert pupfish that resides in the aquifer known as Devil's Hole. Studies the desert tortoise and its remarkable adaptations to this desert biome.
Ethiopia's Rift Valley seems a barren landscape, but it hides untold archaeological riches. Dig in with Wild Chronicles and National Geographic researcher Zeray Alemseged and unearth a three-million-year-old baby. This historic discovery of tiny bones may shed new light on man's ancestry. Segment of video from Wild Chronicles Series.
As shown on the History Channel. It is not only a place of natural splendor, but a geologic treasure trove as well. Hidden in the sediments of the rocks in its walls is evidence of the coldest time on our planet--ironic in one of the hottest places on Earth. Death Valley is literally being pulled apart, and the floor is collapsing and is lower than sea level. Here and across much of Nevada is the Basin and Range Province--a series of ridges of mountain ranges that are being pulled apart and the basins between them getting wider and flat as they fill with eroded sediment.
Figure 2.7 (OpenStax, Biology 2e) caption: Bohr diagrams indicate how many electrons fill each principal shell. Group 18 elements (helium, neon, and argon) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration. Elements in other groups have partially filled valence shells and gain or lose electrons to achieve a stable electron configuration.

The Pajaro Valley, in the Monterey Bay area of California, is ideally suited for agriculture. In fact, the Pajaro Valley and the nearby Salinas Valley produce nearly half of the strawberries grown in the United States yearly. But, the water source for the valley is a confined underground aquifer that is slowly being depleted. In January of 2011, the American Institute of Mathematics held a Sustainability Problems workshop with the goal of bringing together mathematicians and industry representatives to work on a variety of sustainability problems, including renewable energy, air quality, water management, and other environmental issues. Part of the National Science Foundation Series “Science Nation.”
Earth's landscape has a wide variety of physical features referred to as landforms. Characteristics of the major landforms are illustrated with footage from North America, including the Grand Canyon, Interior Plains, and the Rocky Mountains. Important terminology includes plain, relief, interior plain, coastal plain, plateau, mountain, hill, valley, canyon, beach, dune, sea cliff, sea stack, ocean, lake, bay, river, and creek.
As shown on the History Channel. The Sierra Nevada, North America's highest mountain range, contains one of the most awe-inspiring geological features on the planet: Yosemite Valley. Walled by sheer 3,000-foot granite cliffs and made from one of the toughest rocks on earth, it is home to the mighty El Capitan and iconic Half Dome. Yet how this extraordinary valley formed has been the subject of controversy for over 100 years. Was it carved by gigantic glaciers or a cataclysmic rifting of the Earth?
Chris Pulliam is a product manager at Great Lakes NeuroTechnologies. He specializes in designing equipment that monitors different signals the body generates. Biomedical engineers work at the intersection of medicine and engineering. Part of the "Career Connections" series.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, as the stars twinkle in the night sky, Moko is thinking of his village. Totemie asks him if she can join him in his quest for the end of the world. The next morning they leave Totemie's village and find their way to a desert where they find strange mountains and a bizarre twisting valley, deep and narrow, that seems to go on forever. A man crosses their path and tells them that only the pure of heart and courageous ever find the end of the deep valley. Filled with courage they set off to find it. Moko plays his flute and the mountains echo leads their way through the canyon's maze.
National Geographic Explorer sets out to investigate the magic of Headwall Canyon, a remarkable wilderness 60 miles outside Vancouver.
Discover the agricultural creativity involved in the domestication and proliferation of potatoes. Viewers learn how early Peruvians adapted to nature rather than trying to control it. Part of "The Botany of Desire" series.
Capulin Volcano National Monument was born of fire and forces continually reshaping its surface. It’s a dramatic landscape of mountains, plains, and sky and provides access to some of nature’s most awe-inspiring work in New Mexico.
In this episode, host Dianna Cowern tackles the phenomenon of white rainbows. They are also known as spider web rainbows, and Dianna explains how these form. Part of the "Physics Girl" series.
A collaborative effort between the Murphy family, Trout Unlimited, the Gallatin Valley Land Trust, and the state of Montana established a sustainable solution for competing water interests. Their efforts lead to the restoration of Fridley Creek and also demonstrates the connections between land, water, fish, and humans.
Graphene could make it possible for electricity to move effortlessly through computer chips, thereby allowing computer systems to run faster than ever before. Savings in both heat and energy costs could have graphene replacing silicon as the basis of computer chip construction. Part of the Fast Draw Series.
Some of the world's best preserved fossils are found in the flat-topped ridges of southwestern Wyoming's cold sagebrush desert. Fossilized fishes, insects, plants, reptiles, birds, and mammals are exceptional for their abundance, variety, and detail of preservation. Most remarkable is the story they tell of ancient life in a sub-tropical landscape.
Take a tour of the moon's surface. Images and topographic maps show craters, rocks, mountains, basins, and valleys found on the moon. These maps help improve scientific understanding of how Earth's moon and other rocky planets in the solar system evolved.
Students will trace the history of chemistry and study accounts of how chemistry developed from a practical discipline into a science. This episode also presents a current, real-life application of chemistry by illustrating the process of the refining and purifying pure silicon for advanced electronics, such as cell phones and solar cells. Part of the Chemistry: Challenges and Solutions Series.
