Physical world and mathematics

Geoffrey Eglinton

Geoffrey Eglinton (1927–2016) was a British chemist whose insights into the geological fate of organic compounds made him the father of modern organic geochemistry and pioneer of molecular-fossil research.

Geoffrey Horrocks (mathematician)

Geoffrey Horrocks was a British mathematician who worked on vector bundles on projective space, a professor at Newcastle University until 1998, and namesake of the Horrocks construction, the Horrocks–Mumford bundle, and monads.

Geoffrey Ingram Taylor

Sir Geoffrey Ingram Taylor (1886–1975) was a British physicist and mathematician at Trinity College, Cambridge, known for work on turbulence, shock waves, and plastic deformation.

Geoffrey Marcy

Geoffrey Marcy, born 1954, is an American astronomer who discovered more than 100 exoplanets and resigned from UC Berkeley in 2015 after a harassment investigation.

Geoffrey W. Coates

Geoffrey W. Coates (born 1966) is an American chemist, the Tisch University Professor at Cornell University, known for catalysts that make polymers from carbon dioxide and recyclable plastics.

Geoffrey Watson

Geoffrey Stuart Watson (1921–1998) was an Australian statistician who co-invented the Durbin–Watson test, co-authored the Nadaraya–Watson estimator, and founded directional statistics while chairing Princeton's statistics department.

Geoffrey West

Geoffrey West, born 1940 in England, is a British-born theoretical physicist and Santa Fe Institute professor known for scaling laws of life, cities, and companies.

Geoffrey Wilkinson

Sir Geoffrey Wilkinson (1921–1996) was a British inorganic chemist at Imperial College London who shared the 1973 Nobel Prize in Chemistry for work on organometallic sandwich compounds.

Geoffroy Hautier

Geoffroy Hautier is a computational materials scientist, Trustee Professor at Rice University, co-developer of the Materials Project database, and a 2025 fellow of the American Physical Society.

GeoGebra

GeoGebra is a free, open-source suite of interactive mathematics software combining geometry, algebra, and calculus, founded by Markus Hohenwarter in 2001 and used by over 100 million students.

Geographical zone

A geographical zone, also called a geographical climate zone, is one of the principal zones into which the Earth is divided by climate, roughly demarcated by latitude and altitude.

Geographically weighted regression

Geographically weighted regression (GWR) is a local regression method, introduced by Brunsdon, Fotheringham, and Charlton in 1996, that fits separate coefficients at every location using distance-based weights.

Geoid

The geoid is the equipotential surface of Earth's gravity field that best fits global mean sea level; it is irregular, undulating above and below a reference ellipsoid.

Geoinformatics

Geoinformatics is the science and technology dealing with the structure, capture, storage, processing, and dissemination of spatial information, resting on Geographic Information Systems and remote sensing, with applications from urban planning to disaster response.

Geologic hazard

A geologic hazard is a natural hazard of geological origin, such as an earthquake, landslide, volcano, or sinkhole, that can cause loss of life or property damage.

Geologic map

A geologic map is a map showing the distribution of rock and sediment units at the Earth's surface, with colors and symbols marking units of different age, composition, and origin.

Geologic modeling

Geologic modeling is the construction of digital 3D representations of the Earth's subsurface using explicit or implicit methods, allowing estimation of properties like permeability at any point.

Geologic temperature record

The geologic temperature record reconstructs past surface and water temperatures from physical, chemical, and biological proxies in rocks, sediments, and ice, reaching back millions of years before thermometers.

Geologic time scale

The geologic time scale divides Earth's roughly 4.6-billion-year history into eons, eras, periods, epochs, and ages, with boundaries set by the International Commission on Stratigraphy and dated radiometrically.

Geological CO2 storage

Geological CO2 storage is the disposal stage of carbon capture and storage, placing captured CO2 in deep porous rock formations such as saline aquifers and depleted oil and gas fields.

Geological formation

A geological formation, also called a stratigraphic formation, is the primary formal unit of lithostratigraphy: a rock body defined by lithology and mappable, ranking below group and above member.

Geological heritage

Geological heritage, or geoheritage, is the set of rocks, minerals, fossils, soils, landforms, and landscapes with scientific, educational, cultural, or aesthetic value, conserved through geoconservation at sites called geosites.

Geological Magazine

Geological Magazine is a British peer-reviewed geology journal founded in 1864 by Henry Woodward and published by Cambridge University Press, one of the oldest continuously published Earth science periodicals.

Geological map

A geological map, also called a geologic map, shows where rock units, surficial deposits, and structures such as faults and folds lie at or beneath the surface.

Geological Phenomena

Geological phenomena are structures, properties, and processes involving Earth's inanimate matter (MeSH D055593): earthquakes, volcanic eruptions, landslides, tsunamis, erosion, and plate tectonics, studied for hazard forecasting.

Geological Society of America

The Geological Society of America, founded in 1888 and headquartered in Boulder, Colorado, supports geoscientists in more than 100 countries through meetings, publications, and grants.

Geological Society of London

The Geological Society of London, founded in 1807, is the world's oldest geological society and the UK's professional body for geoscience, based at Burlington House, Piccadilly.

Geological survey

A geological survey is a systematic inventory of a territory's rocks, sediments, water, and mineral resources, carried out by a public organization such as the USGS.

Geological Survey of Canada

The Geological Survey of Canada is Canada's national geoscience organization, founded in 1842 under its first director William Logan and now part of Natural Resources Canada.
