Milagro, the Multiple Institution Los Alamos Gamma Ray Observatory, was a water Cherenkov detector in the Jemez Mountains near Los Alamos, New Mexico, operating from 2000 to 2008.

Milan Mrksich

Milan Mrksich is an American chemist and bioengineer, the Henry Wade Rogers Professor at Northwestern University, known for SAMDI mass spectrometry and self-assembled monolayer surfaces for drug discovery.

Milankovitch cycles

Milankovitch cycles, or Milankovitch variations, are periodic changes in Earth's orbital eccentricity, axial tilt, and precession that redistribute sunlight and pace ice ages, named for Serbian mathematician Milutin Milankovitch.

Mild solution

A mild solution solves a differential equation, typically a stochastic partial differential equation, through an integral formulation using the semigroup of the leading operator instead of classical derivatives.

Mild-slope equation

The mild-slope equation, derived by J. C. W. Berkhoff in 1972, is an elliptic partial differential equation describing water waves over slowly varying seabeds, widely used in coastal engineering.

Mildred S. Dresselhaus

Mildred S. Dresselhaus, known as the "queen of carbon science", was an American MIT physicist whose research on graphite, carbon nanotubes, and graphene reshaped carbon science.

Mile

The mile, also called the imperial mile, is a British and American unit of length equal to 5,280 feet or exactly 1,609.344 meters, derived from the Roman mille passus, meaning 1,000 paces.

Miles Aylmer Fulton Barnett

Miles Aylmer Fulton Barnett (1901–1979) was a New Zealand physicist who gave the first experimental proof of the ionosphere, then directed the New Zealand Meteorological Service from 1939 to 1962.

Miles J. Padgett

Miles J. Padgett is an optical physicist who holds the Kelvin Chair at the University of Glasgow and studies shaped light beams, including orbital angular momentum.

Miles Reid

Miles Reid, born 1948, is a British algebraic geometer at the University of Warwick, a Fellow of the Royal Society who laid the foundations of the minimal model program for 3-folds.

Miles V. Klein

Miles V. Klein, also known as Miles Vincent Klein, was an American condensed matter physicist at Illinois whose group made the first Raman measurement of the superconducting gap.

Mileva Marić (Милева Марић)

Mileva Marić (Милева Марић), also known as Mileva Einstein-Maric, was a Serbian mathematician and physicist and the first wife of Albert Einstein, the only woman in her class at the Zurich Polytechnic.

Milko E. van der Boom

Milko E. van der Boom is a materials chemist at the Weizmann Institute of Science in Israel, known for electrochromic films and chiral metal-organic framework crystals.

Milky Way

The Milky Way is the barred spiral galaxy that contains the Solar System, a disk over 100,000 light-years across whose central black hole, Sagittarius A, was first imaged in 2022.

Milky Way circumgalactic medium

The Milky Way circumgalactic medium (CGM) is the reservoir of hot and cool gas surrounding the Galaxy's disc, mediating all gas exchange with intergalactic space.

Milky Way disk warp

The Milky Way disk warp is the bending of the Galactic disk out of its mean plane, first detected in 1957 and traced in stars by the Gaia satellite.

Milky Way–Large Magellanic Cloud collision

The Milky Way–Large Magellanic Cloud collision is the predicted merger between the Milky Way and the Large Magellanic Cloud, expected in roughly 2 to 4 billion years, well before any merger with Andromeda.

Milky Way's central bar

The Milky Way's central bar is an elongated structure of stars at the Galaxy's center, several kiloparsecs long, tilted about 25 to 30 degrees from our line of sight.

Milky Way's dark matter halo

The Milky Way's dark matter halo is the extended, roughly spherical distribution of invisible mass embedding the Galaxy, reaching at least 200,000 light-years from the Galactic center.

Mill's methods

Mill's methods are five rules of inductive inference set out by John Stuart Mill in A System of Logic (1843) for identifying a phenomenon's cause by comparing cases.

Millard H. Alexander

Millard H. Alexander, born 1943 in Boston, is an American theoretical chemist who spent 50 years at the University of Maryland studying quantum dynamics of molecular collisions.

Millennium

A millennium is a period of 1,000 years, from Latin mille and annus; the 3rd millennium of the Christian era began on 1 January 2001, without a year zero.

Millennium Cohort Study

The Millennium Cohort Study, known to participants as Child of the New Century, is a UK study following about 19,000 people born between 2000 and 2002.

Millennium Drought

The Millennium Drought, also called the Big Dry, was a prolonged 2001–2009 drought in southeast Australia, the region's lowest rainfall since 1900, which reshaped Australian water policy.

Millennium Prize Problems

The Millennium Prize Problems, also called the Clay Prize problems, are seven central mathematical questions named in 2000, each carrying a $1 million prize from the Clay Mathematics Institute.

Millennium Simulation

The Millennium Simulation, also called the Millennium Run, is a 2004 computer simulation of dark matter structure growth, run by the Virgo Consortium and published in 2005.

Millennium Star Atlas

The Millennium Star Atlas is a three-volume all-sky printed star atlas published in 1997 by Sky Publishing and ESA, charting about one million stars to magnitude 11 on 1,548 charts.

Millennium-XXL

Millennium-XXL (MXXL) is a large cosmological N-body simulation of structure formation in a dark matter universe, run with 303 billion particles in a 4.1 Gpc cube.

Miller effect

The Miller effect, or Miller capacitance, makes a feedback capacitor at an amplifier's input look (1 + gain) times larger, limiting bandwidth; the cascode reduces it.
