Squeeze cementing
Squeeze cementing is a remedial well operation in which cement slurry is pressured into perforations, leaks, and annular channels, dehydrating to form a solid seal.
Squeeze film
A squeeze film is a thin fluid layer trapped between two surfaces approaching along the normal direction; its viscous pressure buildup supports load, one of three fluid-film lubrication modes.
Squeeze film damper
A squeeze film damper (SFD) is a hydrodynamic vibration damper whose non-rotating journal squeezes an oil film, damping vibration in jet engines and other rotating machinery.
Squeeze film levitation
Squeeze film levitation, also called near-field acoustic levitation (NFAL), suspends an object contactlessly on a thin fluid film compressed by a vibrating surface, used in semiconductor and MEMS handling.
Squeeze flow
Squeeze flow, also called squeezing flow, is the flow of a material compressed between approaching parallel plates, forcing it outward radially; it is used to measure very viscous and yield-stress materials.
Squeeze play (bridge)
The squeeze play in contract bridge is an end-game maneuver in which running an established long suit forces one defender to abandon the guard of one of two suits, creating an extra trick for declarer.
Squeeze plug (wellbore)
A squeeze plug is a volume of cement forced under pressure into a wellbore's perforations or channels to seal off fluid flow, a remedial technique introduced in the 1930s.
Squeeze theorem
The squeeze theorem, also called the sandwich theorem or pinching theorem, states that a function trapped between two functions with the same limit has that limit.
Squeeze-and-Excitation network
The Squeeze-and-Excitation network (SENet) is a convolutional neural network architecture proposed in September 2017 by Hu et al. that recalibrates channel-wise feature responses via its SE block, winning ILSVRC 2017.
Squeezed coherent state
A squeezed coherent state, also called a squeezed state, is a quantum state of light with reduced uncertainty in one quadrature at the price of increased uncertainty in the conjugate quadrature.
Squeezed-light enhancement of gravitational-wave detectors
Squeezed vacuum injection is a quantum-optical technique that injects squeezed vacuum into gravitational-wave detectors like LIGO and Virgo, reducing quantum noise below the standard quantum limit since 2010.
Squeezed-light metrology
Squeezed-light metrology, or squeezed-light measurement, uses squeezed states of light to beat the standard quantum limit, proposed by Carlton Caves in 1981 and used in LIGO.
Squib (explosive)
A squib is a small explosive device producing a burst of flame to ignite a larger charge, used in airbags, mining fuses, and film bullet-hit effects.
Squib load
A squib load, or squib round, is a firearms malfunction in which a cartridge fires weakly and the bullet may remain lodged in the barrel, risking destruction if another is fired.
Squid
Squid: marine cephalopod molluscs with eight arms, two tentacles, and a chitinous gladius, in orders Myopsida, Oegopsida, Bathyteuthida, Sepiolida, and Idiosepiida; major world fisheries, ~3.3 million tonnes cephalopod catch in 2001.
SQUID
A SQUID (superconducting quantum interference device) is an extremely sensitive magnetometer based on a superconducting loop with Josephson junctions, invented in 1964 and widely used to measure brain activity.
Squid (game)
Squid game (오징어 게임) is a traditional Korean children's playground game played on a squid-shaped court; it lent its name to Netflix's 2021 survival drama Squid Game and its six fatal children's games.
Squid (software)
Squid is a free, open-source caching proxy server for web traffic, based on the early-1990s Harvest Cache Daemon, providing access control, logging, and caching for forward and reverse proxying.
Squid as food
Squid as food (calamari, ika): eating squid mantle, fins, and tentacles, a lean seafood of 60–80% edible yield, 15–19% protein, central to East Asian and Mediterranean cuisines and supplied by the world's largest squid fishery, the South Pacific jumbo flying squid.
Squid Game (오징어 게임)
Squid Game (오징어 게임) is Hwang Dong-hyuk's South Korean Netflix survival drama in which 456 indebted players play deadly children's games. Three seasons (2021, 2024, 2025), Netflix's most-watched series, Emmy-winning.
Squid Game season 1
Squid Game season 1 (오징어 게임) is the nine-episode 2021 Netflix Korean survival drama by Hwang Dong-hyuk: 456 debtors play deadly children's games for 45.6 billion won; Netflix's most-watched launch, six Emmy wins.
Squid Game season 2
Squid Game season 2 (오징어 게임 2, Squid Game 2): second season of the Korean Netflix survival thriller, released December 26, 2024 in seven episodes; Gi-hun returns, the Front Man infiltrates as Young-il, 192.6 million views.
Squid Game season 3
Squid Game season 3 (오징어 게임 시즌 3) is the six-episode final season of Netflix's Korean survival drama, released June 27, 2025. It set debut records with 60.1 million views in three days, topped charts in 93 countries, and drew divided reviews.
Squid Game: The Challenge
Squid Game: The Challenge is a Netflix reality competition series, greenlit June 2022, in which 456 players compete for $4.56 million; Season 1 premiered November 22, 2023, Season 2 in November 2025, won by Perla Figuereo.
Squid giant axon
Squid giant axon (Loligo giant nerve fiber): an unmyelinated axon up to 1 mm wide driving squid escape jetting at 10–20 m/s; the preparation of the 1952 Hodgkin–Huxley action potential model and 1963 Nobel Prize.
Squid giant synapse
Squid giant synapse: large glutamatergic synapse in the squid stellate ganglion's giant fiber system (escape circuit), classical preparation that established calcium-triggered, quantal, nanodomain-coupled neurotransmitter release.
SQUID magnetometry
SQUID magnetometry measures a sample's magnetic moment with a superconducting quantum interference device, the most sensitive magnetic flux detector, combining flux quantization and Josephson tunneling.
Squid ring teeth protein
Squid ring teeth protein is the family of silk-like proteins called suckerins that form the hard gripping teeth in squid and cuttlefish suckers, entirely without minerals.
SQUID-on-tip microscopy
SQUID-on-tip microscopy, or SOT, is a scanning probe technique that images magnetic fields, currents, and heat dissipation at the nanoscale using a nanoSQUID on a sharp tip.
Squid-sucker adhesive patch
A squid-sucker adhesive patch is a bioinspired medical adhesive that borrows squid sucker ring teeth or cephalopod suction-cup architecture to bond to wet, soft tissue.
