Geology (from the Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body (such as the geology of the Moon or Mars).
Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates. Geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change. Geology also plays a role in geotechnical engineering and is a major academic discipline.
The majority of geological data comes from research on solid Earth materials. These typically fall into one of two categories: rock and unconsolidated material.
Wikipedia (i/ˌwɪkᵻˈpiːdiə/ or
i/ˌwɪkiˈpiːdiə/ WIK-i-PEE-dee-ə) is a free-access, free-content Internet encyclopedia, supported and hosted by the non-profit Wikimedia Foundation. Those who can access the site can edit most of its articles. Wikipedia is ranked among the ten most popular websites, and constitutes the Internet's largest and most popular general reference work.
Jimmy Wales and Larry Sanger launched Wikipedia on January 15, 2001. Sanger coined its name, a portmanteau of wiki and encyclopedia. Initially only in English, Wikipedia quickly became multilingual as it developed similar versions in other languages, which differ in content and in editing practices. The English Wikipedia is now one of 291 Wikipedia editions and is the largest with 5,081,662 articles (having reached 5,000,000 articles in November 2015). There is a grand total, including all Wikipedias, of over 38 million articles in over 250 different languages. As of February 2014, it had 18 billion page views and nearly 500 million unique visitors each month.
Dr. Paul K. Weimer (November 5, 1914 – January 6, 2005) was a noted contributor to the development of television and the thin-film transistor (TFT).
Weimer was born in Wabash, Indiana. He received a B.A. in math and physics from Manchester University (Indiana) in 1936, an M.A. in physics from the University of Kansas in 1938, and a Ph.D. in physics from Ohio State University in 1942. He then joined the RCA laboratory in Princeton, New Jersey, where he worked until retirement in 1981.
His first assignment was to develop an electron multiplier to go with the Image Orthicon. This tube, which proved to be 100 times more sensitive than its predecessors, was used for the first 20 years of television broadcasting in the United States. In 1960 Weimer began making thin-film transistors in a coplanar process on glass substrates. In a typical process, he would deposit a gold source and drain, then deposit polycrystalline semiconductor material, and place a gate on top. After he placed an insulator between the gate and semiconductor, he got excellent results, as published in his 1962 paper, "The TFT: A New Thin-Film Transistor", in the Proceedings of the IRE.
A national park is a park in use for conservation purposes. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. An international organization, the International Union for Conservation of Nature (IUCN), and its World Commission on Protected Areas, has defined "National Park" as its Category II type of protected areas.
While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. The first area to use "national park" in its creation legislation was the US's Mackinac Island, in 1875. Australia's Royal National Park, established in 1879, was the world's third official national park. In 1895 ownership of Mackinac Island was transferred to the State of Michigan as a state park and national park status was consequently lost. As a result, Australia's Royal National Park is by some considerations the second oldest national park now in existence.

Plot: INTER SCI climatologist Dr. David Kotzman has evidence that a shift in the Earth's polarity triggered the last Ice Age...in a single day. Now, it's happening again, and there's no time to escape. As the temperature plummets, Miami is blasted with snow and ice. Evacuation routes are jammed. The only chance David, his old flame Bryn, and a few other hopeful survivors have is to hole themselves up in a special chamber at INTER SCI. A desperate race for survival is ignited as nature's fury rages and the temperature plunges toward -459.67° F...ABSOLUTE ZERO!

The video begins with a brief description of rocks, minerals, and the rock cycle. Plate tectonics is used to describe structure near plate boundaries. Hot spots and natural hazards (like volcanos, earthquake, and tsunamis) are included. Do you speak another language?

Ours is not a landscape for the timid. In this explanation of a geology that has inspired and frustrated every generation, we examine the forces that unite us and divide us, and bind us together as a state. Credits include Aaron Kunz as a Videographer.

This 25-minute movie illustrates the geologic evolution of Colorado through time, and premiered at the Opening Ceremony of the AAPG Convention in Denver on 31 May 2015. This version has been modified slightly from the version previously shown. The movie is one portion of a large outreach project in which scientifically accurate animations are created for outreach presentations. A longer movie is in preparation that is designed for a more general audience. We will post that version as soon as it is finished. Visit our website at igp.colorado.edu for more videos.
