Johns Hopkins University in the context of "Marcel Detienne"

The American Journal of Psychology is a journal devoted primarily to experimental psychology. It is the first such journal to be published in the English language (though Mind, founded in 1876, published some experimental psychology earlier). AJP was founded by the Johns Hopkins University psychologist Granville Stanley Hall in 1887. This quarterly journal has distributed several groundbreaking papers in psychology. The AJP investigates the science of behavior and the mind, releasing reports of original research based on experimental psychology, theoretical presentations, combined theoretical and experimental analyses, historical commentaries, and detailed reviews of well-known books.

Thomas Woodrow Wilson (December 28, 1856 – February 3, 1924) was the 28th president of the United States, serving from 1913 to 1921. He was the only Democrat to serve as president during the Progressive Era when Republicans dominated the presidency and legislative branches. As president, Wilson changed the nation's economic policies and led the United States into World War I. He was the leading architect of the League of Nations, and his stance on foreign policy came to be known as Wilsonianism.

Born in Staunton, Virginia, Wilson grew up in the Southern United States during the American Civil War and Reconstruction era. After earning a Ph.D. in history and political science from Johns Hopkins University, Wilson taught at several colleges prior to being appointed president of Princeton University, where he emerged as a prominent spokesman for progressivism in higher education. Wilson served as the governor of New Jersey from 1911 to 1913, during which he broke with party bosses and won the passage of several progressive reforms.

A research university or a research-intensive university is a university that is committed to research as a central part of its mission. They are "the key sites of knowledge production", along with "intergenerational knowledge transfer and the certification of new knowledge" through the awarding of doctoral degrees, and continue to be "the very center of scientific productivity". They can be public or private, and often have well-known brand names.

Undergraduate courses at many research universities are often academic rather than vocational and may not prepare students for particular careers, but many employers value degrees from research universities because they teach fundamental life skills such as critical thinking. Globally, research universities are overwhelmingly public institutions, while some countries like the United States and Japan also have well-known private research institutions.

The Johns Hopkins University Applied Physics Laboratory (also known simply as Applied Physics Laboratory or APL) is a not-for-profit, United States Navy-sponsored, university-affiliated research center (UARC) in Howard County, Maryland, United States.

APL is affiliated with Johns Hopkins University and employs more than 8,800 people as of 2025. APL is the nation's largest UARC. APL conducts research, engineering and analysis to address national security and scientific challenges faced by the United States and its allies. The Laboratory brings together technical expertise, longstanding experience and specialized facilities to support rapid prototyping and long-term research and development. APL works across a range of domains, contributing to both operational systems and foundational science and technology.

The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST), science operations and mission operations center for the James Webb Space Telescope (JWST), and science operations center for the Nancy Grace Roman Space Telescope. STScI was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA). STScI's offices are located on the Johns Hopkins University Homewood Campus and in the Rotunda building in Baltimore, Maryland.

In addition to performing continuing science operations of HST and preparing for scientific exploration with JWST and Roman, STScI manages and operates the Mikulski Archive for Space Telescopes (MAST), which holds data from numerous active and legacy missions, including HST, JWST, Kepler, TESS, Gaia, and Pan-STARRS.

The Wilkinson Microwave Anisotropy Probe (WMAP), originally known as the Microwave Anisotropy Probe (MAP and Explorer 80), was a NASA spacecraft operating from 2001 to 2010 which measured temperature differences across the sky in the cosmic microwave background (CMB) – the radiant heat remaining from the Big Bang. Headed by Professor Charles L. Bennett of Johns Hopkins University, the mission was developed in a joint partnership between the NASA Goddard Space Flight Center and Princeton University. The WMAP spacecraft was launched on 30 June 2001 from Florida. The WMAP mission succeeded the COBE space mission and was the second medium-class (MIDEX) spacecraft in the NASA Explorer program. In 2003, MAP was renamed WMAP in honor of cosmologist David Todd Wilkinson (1935–2002), who had been a member of the mission's science team. After nine years of operations, WMAP was switched off in 2010, following the launch of the more advanced Planck spacecraft by European Space Agency (ESA) in 2009.

WMAP's measurements played a key role in establishing the current Standard Model of Cosmology: the Lambda-CDM model. The WMAP data are very well fit by a universe that is dominated by dark energy in the form of a cosmological constant. Other cosmological data are also consistent, and together tightly constrain the Model. In the Lambda-CDM model of the universe, the age of the universe is 13.772±0.059 billion years. The WMAP mission's determination of the age of the universe is to better than 1% precision. The current expansion rate of the universe is (see Hubble constant) 69.32±0.80 km·s·Mpc. The content of the universe currently consists of 4.628%±0.093% ordinary baryonic matter; 24.02%+0.88%
−0.87% cold dark matter (CDM) that neither emits nor absorbs light; and 71.35%+0.95%
−0.96% of dark energy in the form of a cosmological constant that accelerates the expansion of the universe. Less than 1% of the current content of the universe is in neutrinos, but WMAP's measurements have found, for the first time in 2008, that the data prefer the existence of a cosmic neutrino background with an effective number of neutrino species of 3.26±0.35. The contents point to a Euclidean flat geometry, with curvature (${\displaystyle \Omega _{k}}$) of −0.0027+0.0039
−0.0038. The WMAP measurements also support the cosmic inflation paradigm in several ways, including the flatness measurement.

Thomas Woodrow Wilson (December 28, 1856 – February 3, 1924) was an American politician and academic who served as the 28th president of the United States. The early life of Woodrow Wilson covers the time period from his birth in late 1856 through his entry into electoral politics in 1910. Wilson spent his early years in the American South, mainly in Augusta, Georgia, during the Civil War and Reconstruction. After earning a Ph.D. in political science from Johns Hopkins University, Wilson taught at various schools before becoming the president of Princeton University. Wilson later went onto become governor of New Jersey from 1911 to 1913, a major progressive reformer and then finally, President of the United States from 1913 to 1921.
