paragraph_text: A gyrotron is a class of high-power linear-beam vacuum tubes which generates millimeter-wave electromagnetic waves by the cyclotron resonance of electrons in a strong magnetic field. Output frequencies range from about 20 to 527 GHz, covering wavelengths from microwave to the edge of the terahertz gap. Typical output powers range from tens of kilowatts to 1–2 megawatts. Gyrotrons can be designed for pulsed or continuous operation.

paragraph_text: America Is in the Heart, sometimes subtitled A Personal History, is a 1946 semi-autobiographical novel written by Filipino American immigrant poet, fiction writer, short story teller, and activist, Carlos Bulosan. The novel was one of the earliest published books that presented the experiences of the immigrant and working class based on an Asian American point of view and has been regarded as "[t]he premier text of the Filipino-American experience." In his introduction, journalist Carey McWilliams, who wrote a 1939 study about migrant farm labor in California ("Factories in the Field"), described "America Is in the Heart" as a “social classic” that reflected on the experiences of Filipino immigrants in America who were searching for the “promises of a better life”.

paragraph_text: Anton Zeilinger (; born 20 May 1945) is an Austrian quantum physicist who in 2008 received the Inaugural Isaac Newton Medal of the Institute of Physics (UK) for "his pioneering conceptual and experimental contributions to the foundations of quantum physics, which have become the cornerstone for the rapidly-evolving field of quantum information". Zeilinger is professor of physics at the University of Vienna and Senior Scientist at the Institute for Quantum Optics and Quantum Information IQOQI at the Austrian Academy of Sciences. Most of his research concerns the fundamental aspects and applications of quantum entanglement.

paragraph_text: In mathematics, a Killing vector field (often just Killing field), named after Wilhelm Killing, is a vector field on a Riemannian manifold (or pseudo-Riemannian manifold) that preserves the metric. Killing fields are the infinitesimal generators of isometries; that is, flows generated by Killing fields are continuous isometries of the manifold. More simply, the flow generates a symmetry, in the sense that moving each point on an object the same distance in the direction of the Killing vector will not distort distances on the object.

paragraph_text: The Kantorovich inequality is named after Soviet economist, mathematician, and Nobel Prize winner Leonid Kantorovich, a pioneer in the field of linear programming.

paragraph_text: Strawberry Fields is a 2.5-acre (1.0 ha) landscaped section in New York City's Central Park, designed by the landscape architect Bruce Kelly, that is dedicated to the memory of former Beatles member, John Lennon. It is named after the Beatles' song "Strawberry Fields Forever" written by Lennon. The song is itself named for the former Strawberry Field children's home in Liverpool, England, located near Lennon's childhood home.

paragraph_text: Cherry Spur () is a prominent rock spur that forms the southwest portion of Sculpture Mountain at the southern end of the Monument Nunataks, Victoria Land, Antarctica. The feature was geologically studied by Ohio State University field parties in the 1981–82 and 1982–83 seasons, and named by the Advisory Committee on Antarctic Names after Eric M. Cherry, geologist with those parties who worked on the spur. The spur lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

paragraph_text: The GHZ experiments are named for Daniel M. Greenberger, Michael A. Horne, and Anton Zeilinger (GHZ) who first analyzed certain measurements involving four observers and who subsequently (together with Abner Shimony (GHSZ), upon a suggestion by David Mermin) applied their arguments to certain measurements involving three observers.

paragraph_text: Koert Vermeulen (born 1967 in Antwerp, Belgium) is a lighting designer, with over 20 years of experience in the fields of architecture, entertainment and art installations.

paragraph_text: Hall Bluff () is a prominent rock bluff, high, that forms the east end of Dais and marks the valley entrances to North Fork and South Fork in Wright Valley, Victoria Land, Antarctica. It was named by the Advisory Committee on Antarctic Names (1997) after Brenda Hall, a Research Assistant at the Department of Geological Sciences, University of Maine from 1990, and a field party geologist in six United States Antarctic Program supported field seasons, 1990–91 to 1995–96, including work in Wright Valley in the proximity of this bluff.

paragraph_text: The name "Pennington Field" was first given to an existing American football field near what was then L. D. Bell High School (now the site of Central Junior High). The field was named for Fred Pennington, the L.D. Bell High School football coach, after his accidental death in 1962.

paragraph_text: Dreschhoff Peak () in Antarctica is named after Gisela A.M. Dreschhoff, a physicist at the Space Technology Center, University of Kansas, who conducted radioactivity surveys and other field work in various parts of Antarctica, including Victoria Land, for 11 field seasons, 1976–89.

paragraph_text: A Helmholtz coil is a device for producing a region of nearly uniform magnetic field, named after the German physicist Hermann von Helmholtz. It consists of two electromagnets on the same axis. Besides creating magnetic fields, Helmholtz coils are also used in scientific apparatus to cancel external magnetic fields, such as the Earth's magnetic field.

paragraph_text: Tapan K. Datta is a Wayne State University civil engineering professor and researcher who highly specializes in transportation engineering and safety. After receiving his early schooling, undergraduate degrees, and field experience in Calcutta, India, he moved to the United States to complete his master’s and doctoral degrees. While in Detroit, MI, he worked for and later owned Goodell Grivas, Inc., a structural engineering consulting firm, and became a full-time faculty member at Wayne State University in 1973. His most notable contributions include work on the roof of Cobo Hall, in Detroit, MI, and the steel structural work done on Jacobs Field (now Progressive Field) in Cleveland, OH.

paragraph_text: On June 10, 2013, Apple released another update in the same form factor as the 2012 model during the company's Worldwide Developer Conference (WWDC). The 11 ''and 13'' models have a minimum standard 4 GB RAM, with a maximum configuration of 8 GB. Both models are powered by the Haswell ULT 1.3 GHz dual - core Intel Core i5 processors, with Turbo Boost up to 2.6 GHz, while a 1.7 GHz Dual - Core i7, with Turbo Boost up to 3.3 GHz, option is also available. Each model's storage standard is 128 GB SSD, upgradeable to 256 GB and 512 GB SSD. Due to Haswell CPUs, battery life has considerably improved from the previous generation, and the mid-2013 models are capable of 9 hours on the 11 ''model and 12 hours on the 13'' model; a team of reviewers exceeded expected battery life ratings during their test.

paragraph_text: Robert Weber (1926–2008) was an American astronomer and discoverer of minor planets who ran the precursor to the LINEAR project shortly before his retirement in 1996. Data were collected by manually entering telescope pointing positions and requesting an image save. Searching twenty fields was a taxing experience. They did have automatic object detection working, but no starfield matching at that time.
