Giuseppe Gigli (born 1970 in Rome) is an Italian physicist and nanotechnologist, full professor at the University of Salento and founder of the CNR Institute of Nanotechnology in 2015.
Giuseppe Marrucci
Giuseppe (Pino) Marrucci, born 1937 in Naples, is an Italian chemical engineer at the Università di Napoli Federico II known for reshaping the theory of entangled polymer dynamics.
Giuseppe Mercalli
Giuseppe Mercalli was an Italian priest, volcanologist, and seismologist who taught at the University of Naples from 1892 and whose earthquake intensity scale became the Modified Mercalli scale.
Giuseppe Occhialini
Giuseppe Occhialini, known to colleagues as Beppo, was an Italian experimental physicist who helped discover the positron's pair production in cosmic rays and, in 1947, the charged pion.
Giuseppe Oddo
Giuseppe Oddo (1865–1954) was an Italian chemist born at Caltavuturo near Palermo, the last exponent of Cannizzaro's Palermo chemical school, remembered for an early bicyclic structure of camphor and the mesoidria hypothesis.
Giuseppe Peano
Giuseppe Peano (1858–1932) was an Italian mathematician and logician at the University of Turin who formulated the Peano axioms and found the first space-filling curve.
Giuseppe Sansone
Giuseppe Sansone (born 1977) is an Italian physicist working on isolated attosecond pulses, and full professor of experimental physics at the University of Freiburg in Germany since 2016.
Giuseppe Vaiana
Giuseppe Vaiana (died 1991) was an Italian astrophysicist who led solar and stellar X-ray astronomy at AS&E, directed Skylab's S-054 telescope, and rebuilt the Palermo Observatory.
Giuseppe Veronese
Giuseppe Veronese (1854–1917) was an Italian mathematician, professor of geometry at Padua from 1881, who founded the projective geometry of spaces of more than three dimensions.
Giuseppe Vitali
Giuseppe Vitali (1875–1932) was an Italian mathematician who in 1905 constructed the first nonmeasurable set of real numbers, and proved the Vitali covering and convergence theorems.
Givens rotation
A Givens rotation is a plane rotation in numerical linear algebra, acting on two coordinates of a vector to turn one chosen entry into zero.
GJ 3378
GJ 3378 is a red dwarf star of spectral type M4V, located 25.2 light years from the Sun and known for hosting the habitable-zone super-Earth GJ 3378 b.
Gjon Gazulli
Gjon Gazulli is the name of two notable Albanians: a 15th-century Dominican astronomer and diplomat of Ragusa, and a priest martyred in 1927 and beatified in 2024.
GK Persei
GK Persei, or Nova Persei 1901, is a cataclysmic variable star in Perseus that erupted as a bright nova in 1901 and now shows dwarf nova outbursts.
GKP error correction in trapped ions
GKP error correction in trapped ions is the experimental implementation of the Gottesman–Kitaev–Preskill code, which encodes a logical qubit in a single ion's motion; it was first realized at ETH Zurich in 2019.
GKP qubit
A GKP qubit is a logical qubit encoded in a harmonic oscillator using the Gottesman–Kitaev–Preskill code, proposed in 2001 to correct small shifts in position and momentum.
Glacial erosion
Glacial erosion is the removal and transport of bedrock and sediment by glaciers, accomplished mainly through quarrying, abrasion, and subglacial meltwater, carving cirques, U-shaped valleys, and fjords.
Glacial erratic
A glacial erratic, or erratic block, is a rock fragment carried by glacial ice and deposited far from its source, usually resting on bedrock of a different type.
Glacial period
A glacial period, also called a glaciation, is a colder interval within an ice age when continental ice sheets expand; the most recent ended about 11,500 years ago.
Glacier
A glacier, also called a gletscher, is a perennial mass of ice formed on land by compacted snow that moves slowly downslope under gravity, covering nearly a third of Earth's land during the Pleistocene Ice Age.
Glacier collapse
Glacier collapse, also called glacier detachment, is the sudden catastrophic failure of a glacier or ice shelf, from ice shelf disintegration to rock-ice avalanches like Blatten in 2025.
Gladstone Institutes
The Gladstone Institutes is an independent, nonprofit biomedical research organization in San Francisco, founded in 1979 and closely affiliated with UCSF, with about 600 scientists working on cardiovascular, neurological, and infectious disease.
Gladys West
Gladys Mae West, born Gladys Mae Brown, was an American mathematician who spent 42 years at the U.S. Navy's Dahlgren facility modeling the Earth's shape for GPS.
Glaisher's theorem
Glaisher's theorem is an 1883 result stating that partitions into parts not divisible by d equal partitions with no part repeated d or more times.
Glaser coupling
Glaser coupling is the copper-catalyzed oxidative homocoupling of terminal alkynes to form symmetrical 1,3-diynes, first reported by Carl Glaser in 1869 and still the most widely used method for making 1,3-diynes.
Glasgow Climate Pact
The Glasgow Climate Pact is the decision adopted at the COP26 climate summit in Glasgow on 13 November 2021, the first COP decision to mention fossil fuels.
Glashow resonance
The Glashow resonance is the resonant formation of a W⁻ boson when a high-energy electron antineutrino strikes an electron, peaking at an antineutrino energy of 6.3 petaelectronvolts.
Glass
Glass is an amorphous solid whose atoms lack the order of a crystal but which is rigid; most glass is a silicate used for windows, containers, and optical fibers.
