Harold Webb
Harold Donivan Webb (1909 1989) was a physicist and a professor of electrical engineering at the University of Illinois, Urbana-Champaign. In 1946, he was one of the members of the US Army Signal Corps Project Diana team at Camp Evans, New Jersey, that was the first to bounce radar signals off of the Moon. Dr. Webb continued research on ionosphere, moon reflection and radio astronomy at the University of Illinois. One of his daughters, Diana, was named after the Project. The significance of the Diana Project was two-fold. First, it proved that radio waves could penetrate the Earth's ionosphere, a feat that had never before been accomplished. Second, it proved that the echo of a radar beam could be received on Earth, providing a new way to observe and measure objects in space beyond direct observation through a conventional telescope. Project Diana was the beginning of radioastronomy and the space age. Early years Harold Donivan Webb was born September 23, 1909, in Johnson Cou ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Tau Beta Pi
The Tau Beta Pi Association (commonly Tau Beta Pi, , or TBP) is the oldest engineering honor society and the second oldest collegiate honor society in the United States. It honors engineering students in American universities who have shown a history of academic achievement as well as a commitment to personal and professional integrity. Specifically, the association was founded "to mark in a fitting manner those who have conferred honor upon their Alma Mater by distinguished scholarship and exemplary character as students in engineering, or by their attainments as alumni in the field of engineering, and to foster a spirit of liberal culture in engineering colleges". History When academic honor society Phi Beta Kappa sought to restrict its membership to students of the liberal arts in the late 19th century, Edward H. Williams Jr., a member of Phi Beta Kappa and head of the mining department at Lehigh University, formulated the idea of an honor society for those studying technic ...

International Union Of Radio Science
The International Union of Radio Science (abbreviated ''URSI'', after its French name, french: link=no, Union radio-scientifique internationale) is one of 26 international scientific unions affiliated to the International Council for Science (ICSU). History and objectives URSI was officially created in 1919, during the Constitutive Assembly of the International Research Council (now ICSU), based on the earlier french: link=no, Commission Internationale de Telegraphie sans Fil (1913–1914) when the only radio communication system was radiotelegraphy. It has held a general assembly every three years from 1922. Fifty years ago URSI was one of the most important promoters of the International Geophysical Year. It co-sponsors the ''Radio Science'' journal (co-sponsored by the American Geophysical Union) as well as the ''Journal of Atmospheric and Solar-Terrestrial Physics''. URSI's original objective (to encourage "scientific studies of radiotelegraphy, especially those which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indiana Academy Of Science
Indiana () is a U.S. state in the Midwestern United States. It is the 38th-largest by area and the 17th-most populous of the 50 States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th state on December 11, 1816. It is bordered by Lake Michigan to the northwest, Michigan to the north, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Various indigenous peoples inhabited what would become Indiana for thousands of years, some of whom the U.S. government expelled between 1800 and 1836. Indiana received its name because the state was largely possessed by native tribes even after it was granted statehood. Since then, settlement patterns in Indiana have reflected regional cultural segmentation present in the Eastern United States; the state's northernmost tier was settled primarily by people from New England and New York, Central Indiana by migrants from t ...
