MIDA boronates

MIDA boronates are crystalline, air-stable complexes of boronic acids with N-methyliminodiacetic acid, introduced in 2008 and used as protected building blocks for iterative cross-coupling of small molecules.

Middle European Cooperation in Statistical Physics

The Middle European Cooperation in Statistical Physics, known as MECO, is an annual international statistical physics conference held each year in a different European country since 1974.

middle Kaub Formation

Middle Kaub Formation: clay-rich middle part of the Kaub Formation (Lower Emsian, Lower Devonian) in the Hunsrück, Germany; five members, laminated slates with Chondrites, source of the Bundenbach Hunsrück Slate fossils.

Midland Basin

The Midland Basin is a sub-basin of the Permian Basin in West Texas, whose Wolfcamp shale alone was assessed by the USGS at a mean 20 billion barrels of recoverable oil.

Midnight

Midnight is the moment when one calendar day ends and the next begins, written 00:00:00 or 12:00 a.m. at the start of a day and 24:00:00 at its end.

Midnight sun

The midnight sun, or polar day, is the summer phenomenon of the sun staying above the horizon for 24 hours a day north of the Arctic Circle.

Midrange

The midrange is a location estimator in statistics, the average of a sample's smallest and largest values, quick to compute but suited only to symmetric, outlier-free data.

Mie resonance

Mie resonance is the resonant enhancement of light scattering by particles comparable in size to the wavelength, named after Gustav Mie, who solved the problem in 1908.

Mie resonances in dielectric nanoparticles

Mie resonances in dielectric nanoparticles are electromagnetic resonances arising when the light wavelength inside a high-refractive-index particle becomes comparable to its size, producing strong electric and magnetic scattering; they underpin all-dielectric metaphotonics.

Mie scattering

Mie scattering, also known as Lorenz–Mie theory or the Mie solution, is the exact analytical solution of Maxwell's equations for how light scatters from a homogeneous sphere of any size.

Mie-resonant dielectric metasurfaces

Mie-resonant dielectric metasurfaces are planar arrays of high-index dielectric resonators whose optical response is governed by Mie resonances, enabling metalenses, holography, and biosensing with low loss.

Mie-resonant dielectric nanoparticle lasers

Mie-resonant dielectric nanoparticle lasers are nanoscale lasers in which a subwavelength high-refractive-index dielectric particle serves as the resonator, lasing on its electric and magnetic Mie resonances.

Mie–Grüneisen equation of state

The Mie–Grüneisen equation of state, or Mie-Grüneisen equation, relates pressure, density, and internal energy in solids and is the standard equation of state for shock compression.

Miers Fisher Longstreth

Miers Fisher Longstreth (1819–1891) was an American astronomer and physician, a founding member of the National Academy of Sciences, known for an 1850 lunar longitude formula.

Mietek Jaroniec

Mietek Jaroniec, also known as Mieczysław Jaroniec, is a Polish-born materials chemist and professor emeritus at Kent State University known for research on adsorption and ordered nanoporous materials.

Migdal effect

The Migdal effect is the ionization of an atom's electron cloud caused by a sudden jolt to its nucleus, predicted by Arkady Migdal in 1939.

Migmatite

Migmatite is a composite metamorphic rock with two or more distinct parts, at least one formed by partial melting, named by Jakob Johannes Sederholm in 1907 from the Greek for mixture.

Migration velocity analysis

Migration velocity analysis (MVA) is a seismic imaging method that estimates the subsurface velocity model by repeatedly migrating data, measuring kinematic errors in prestack images, and tomographically inverting them into velocity updates.

Migratory insertion

Migratory insertion is an organometallic reaction in which a ligand migrates onto an adjacent metal–ligand bond, the bond-forming step in catalytic processes such as hydroformylation and carbonylation.

Miguel A. Garcia-Garibay

Miguel A. Garcia-Garibay is Distinguished Professor of Chemistry and Dean of Physical Sciences at UCLA, known for amphidynamic crystals and elected to the National Academy of Sciences in 2023.

Miguel Alcubierre

Miguel Alcubierre, also known as Miguel Alcubierre Moya, is a Mexican physicist at UNAM's Instituto de Ciencias Nucleares known for the 1994 warp drive metric and numerical relativity.

Miguel Ángel Virasoro (Argentine physicist)

Miguel Ángel Virasoro (1940–2021) was an Argentine theoretical physicist whose Virasoro algebra became a backbone of string theory; he later co-built spin glass theory with Giorgio Parisi.

Miguel Costas

Miguel Costas, also known as Miquel Costas, is a Spanish inorganic chemist and full professor at the University of Girona known for bioinspired iron and manganese oxidation catalysis.

Miguel Morales

Miguel Morales, also known as Miguel Morales-Silva, is a Puerto Rican computational condensed-matter physicist who won a 2013 PECASE at Lawrence Livermore for high-pressure hydrogen studies.

Mihail Barboiu

Mihail Barboiu is a Romanian-born French chemist, CNRS research director at the Institut Européen des Membranes in Montpellier, known for artificial water channels and the 2024 Prix André Collet.

Mihailo Petrović Alas

Mihailo Petrović Alas (Михаило Петровић Алас, 1868 to 1943) was a Serbian mathematician who founded the Serbian school of mathematics and invented the hydrointegrator, an analog calculating machine.

Mihajlo Pupin

Mihajlo Pupin (Михајло Пупин), 1858–1935, was a Serbian-American physicist and inventor at Columbia University whose loading coils made long-distance telephony practical; he also won the 1924 Pulitzer Prize for his autobiography.

Miho Janvier

Miho Janvier is a French solar and space physicist at ESA's ESTEC, known for 3D models of solar flares and her roles on the Solar Orbiter mission.

Mikael C. Rechtsman

Mikael C. Rechtsman is a Canadian-born physicist and professor at Pennsylvania State University known for the 2013 photonic Floquet topological insulator experiment and four-dimensional quantum Hall physics.

Mikael Käll

Mikael Käll is a full professor of physics at Chalmers University of Technology who leads a bionanophotonics group studying plasmonic nanoantennas, metasurfaces, biosensing, and thermoplasmonics.
