Donald D. Clayton
Donald Delbert Clayton (born March 18, 1935) is an American astrophysicist whose most visible achievement was the prediction from nucleosynthesis theory that supernovae are intensely radioactive. That earned Clayton the NASA Exceptional Scientific Achievement Medal (1992) for “theoretical astrophysics related to the formation of (chemical) elements in the explosions of stars and to the observable products of these explosions”. Supernovae thereafter became the most important stellar events in astronomy owing to their profoundly radioactive nature. Not only did Clayton discover radioactive nucleosynthesis during explosive silicon burning in stars but he also predicted a new type of astronomy based on it, namely the associated gamma-ray line radiation emitted by matter ejected from supernovae. That paper was selected as one of the fifty most influential papers in astronomy during the twentieth century for the Centennial Volume of the American Astronomical Society. He gathered sup ...

Shenandoah, Iowa
Shenandoah is a city in Page and Fremont counties in Iowa, United States. The population was 4,925 at the time of the 2020 U.S. Census. Once referred to as the "seed and nursery center of the world," Shenandoah is the home to Earl May Seed Company and the radio station KMA, founded by Earl E. May. The early live radio stations gave many performers their start, including The Everly Brothers and Charlie Haden. History Shenandoah, originally known as Fair Oaks, was platted in 1870, shortly after the arrival of the Chicago, Burlington and Quincy Railroad into the neighborhood. Its name is derived from the local valley's resemblance to the Shenandoah Valley, in Virginia. Geography Shenandoah is located at (40.762251, -95.370945) along Fourmile Creek near its confluence with the East Nishnabotna River.

Roberto Rossellini
Roberto Gastone Zeffiro Rossellini (8 May 1906 – 3 June 1977) was an Italian film director, producer, and screenwriter. He was one of the most prominent directors of the Italian neorealist cinema, contributing to the movement with films such as ''Rome, Open City'' (1945), ''Paisan'' (1946), and ''Germany, Year Zero'' (1948). Early life Rossellini was born in Rome. His mother, Elettra (née Bellan), was a housewife born in Rovigo, Veneto, and his father, Angiolo Giuseppe "Peppino" Rossellini, who owned a construction firm, was born in Rome from a family originally from Pisa, Tuscany. His mother was of partial French descent, from immigrants who had arrived in Italy during the Napoleonic Wars. He lived on the Via Ludovisi, where Benito Mussolini had his first Roman hotel in 1922 when Fascism obtained power in Italy. Rossellini's father built the first cinema in Rome, the "Barberini", a theatre where movies could be projected, granting his son an unlimited free pass; the young R ...

National Science Foundation
The National Science Foundation (NSF) is an independent agency of the United States government that supports fundamental research and education in all the non-medical fields of science and engineering. Its medical counterpart is the National Institutes of Health. With an annual budget of about $8.3 billion (fiscal year 2020), the NSF funds approximately 25% of all federally supported basic research conducted by the United States' colleges and universities. In some fields, such as mathematics, computer science, economics, and the social sciences, the NSF is the major source of federal backing. The NSF's director and deputy director are appointed by the President of the United States and confirmed by the United States Senate, whereas the 24 president-appointed members of the National Science Board (NSB) do not require Senate confirmation. The director and deputy director are responsible for administration, planning, budgeting and day-to-day operations of the foundation, while t ...

Phi Beta Kappa
The Phi Beta Kappa Society () is the oldest academic honor society in the United States, and the most prestigious, due in part to its long history and academic selectivity. Phi Beta Kappa aims to promote and advocate excellence in the liberal arts and sciences, and to induct the most outstanding students of arts and sciences at only select American colleges and universities. It was founded at the College of William and Mary on December 5, 1776, as the first collegiate Greek-letter fraternity and was among the earliest collegiate fraternal societies. Since its inception, 17 U.S. Presidents, 40 U.S. Supreme Court Justices, and 136 Nobel Laureates have been inducted members. Phi Beta Kappa () stands for ('), which means "Wisdom it. love of knowledgeis the guide it. helmsmanof life". Membership Phi Beta Kappa has chapters in only about 10% of American higher learning institutions, and only about 10% of these schools' Arts and Sciences graduates are invited to join the society. ...

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the so ...

Max Planck Institute For Nuclear Physics
The Max-Planck-Institut für Kernphysik ("MPI for Nuclear Physics" or MPIK for short) is a research institute in Heidelberg, Germany. The institute is one of the 80 institutes of the Max-Planck-Gesellschaft (Max Planck Society), an independent, non-profit research organization. The Max Planck Institute for Nuclear Physics was founded in 1958 under the leadership of Wolfgang Gentner. Its precursor was the Institute for Physics at the MPI for Medical Research. Today, the institute's research areas are: crossroads of particle physics and astrophysics (astroparticle physics) and many-body dynamics of atoms and molecules (quantum dynamics). The research field of Astroparticle Physics, represented by the divisions of Jim Hinton, Werner Hofmann and Manfred Lindner, combines questions related to macrocosm and microcosm. Unconventional methods of observation for gamma rays and neutrinos open new windows to the universe. What lies behind “dark matter” and “dark energy” is theore ...

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected the use ...
