Slessor Peak
Slessor Peak: mainly ice-covered 2,370 m peak at the SW end of Bruce Plateau, Graham Land, Antarctic Peninsula, near Gould Glacier; surveyed 1946-47 by FIDS and named for Robert S. Slessor. Distinct from Slessor Glacier in East Antarctica.
Sleuth (1972 film)
Sleuth (1972), also released as La huella, is Joseph L. Mankiewicz's final film, adapted by Anthony Shaffer from his Tony-winning play, starring Laurence Olivier and Michael Caine in a two-hander battle of wits, with four Oscar nominations and famously fictitious supporting cast credits.
Slew rate
Slew rate is the maximum rate at which an amplifier's output voltage can change, specified in V/µs; exceeding it distorts the waveform. It is a large-signal limitation.
Slewing crane
A slewing crane, in practice usually called a slewing jib crane, is a lifting machine with a horizontal jib that rotates about a vertical axis, carrying a hoist for workstation lifting.
Slice of life
Slice of life: term for presenting unshaped everyday experience, originating in Zola's theatrical naturalism (fourth wall, detailed sets, open endings) and used in fiction, film, and anime-related genres.
Slice preparation
Slice preparation: cutting 300–400 µm living brain sections for acute electrophysiology or long-term organotypic culture, from Harrison's 1907 explant to Stoppini's 1991 membrane-interface method, with ice-cold ACSF cutting and 6–12 hour acute viability.
Slice sampling
Slice sampling is a Markov chain Monte Carlo method introduced by Radford M. Neal in 2003 that samples from a density by uniformly sampling the region under its curve.
Sliced bread
Sliced bread, pre-cut and wrapped loaves first sold July 7, 1928 by Chillicothe Baking Co., Missouri, using Otto Rohwedder's automatic bread-slicing machine; source of the phrase "best thing since sliced bread" and banned briefly in 1943.
Sliced inverse regression
Sliced inverse regression (SIR) is a statistical dimension reduction method that finds linear combinations of predictors carrying a response's information, introduced by Ker-Chau Li in 1991.
Slick Rick
Slick Rick (Richard Martin Lloyd Walters, born 1965, London; earlier MC Ricky D) is a British-American rapper and hip-hop storyteller known for 'La Di Da Di,' 'The Show,' the 1988 platinum debut The Great Adventures of Slick Rick, a 1990 attempted-murder conviction, a 2008 pardon, and the 2025 album Victory.
Slick Woods
Slick Woods, born Simone Thompson (1996), American model and actor discovered by Ash Stymest in LA; face of Fenty Beauty, walked Savage x Fenty nine months pregnant in 2018, melanoma survivor.
Slickline
Slickline is a single-strand, nonelectric steel wire spooled from a surface winch that runs, retrieves, and actuates downhole tools in live oil and gas wells without a workover rig.
Slide
Slide (geography): a landslide mechanism in which rock, debris, or earth moves downslope as a coherent mass along a distinct failure surface; rotational or translational; one of five slope-movement modes; GeoNames code SLID names the resulting landform.
Slide guitar
Slide guitar, also called bottleneck guitar, is a guitar technique using a glass, metal, or porcelain slide or steel bar to sound notes, producing continuous glissando and vibrato; it originated with Joseph Kekuku's Hawaiian steel guitar and shaped blues, country, and rock.
Slide Insurance
Slide Insurance Holdings, Inc. is a Tampa, Florida-based technology-enabled coastal specialty insurer founded by Bruce and Shannon Lucas in 2021, publicly traded on Nasdaq under SLDE since 2025.
Slide It In
Slide It In is Whitesnake's sixth studio album (1984), also known as the band's double-mix release. Recorded at Musicland Studios, Munich; UK mix with Micky Moody, US Keith Olsen remix with John Sykes; UK chart peak 9, US double Platinum.
Slide projector
A slide projector is an optical device that enlarges and displays photographic slides onto a screen, the standard means of showing photos from the mid-twentieth century until digital projection.
Slide rule
The slide rule, also called a slipstick, is a mechanical analog calculator using sliding logarithmic scales for multiplication and division, the standard engineer's tool until about 1970.
Slide show
Slide show (also slideshow): a sequential display of still images, from magic lantern and 35mm photographic slide projection to modern digital slideshow software with transitions, narration, and music.
Slide-seq
Slide-seq is a spatial transcriptomics method, introduced at the Broad Institute in 2019, that transfers RNA from tissue sections onto DNA-barcoded 10 µm beads so gene expression is measured with position preserved.
SlideShare
SlideShare, formerly LinkedIn SlideShare, is a slide hosting service for sharing presentations publicly or privately; founded in 2006, it was acquired by LinkedIn in 2012 and Scribd in 2020.
Sliding autonomy
Sliding autonomy, also known as adjustable autonomy, is a human-robot control approach where the division of control between operator and robot shifts dynamically during task execution.
Sliding clamp
A sliding clamp is a ring-shaped protein that encircles DNA and tethers DNA polymerase to its template, enabling processive replication; examples include the bacterial β clamp and eukaryotic PCNA.
Sliding door
A sliding door is a door that opens by moving horizontally along a track rather than swinging on hinges, saving floor space and enabling wide, glazed openings.
Sliding Doors
Sliding Doors (1998) is a British romantic comedy-drama, Peter Howitt's directorial debut, starring Gwyneth Paltrow as Helen Quilley, whose life splits into two parallel timelines when she catches or misses a London Underground train.
Sliding ferroelectricity in 2D transition metal dichalcogenides
Sliding ferroelectricity in 2D transition metal dichalcogenides switches out-of-plane polarization by sliding atomic layers sideways, first seen in WTe2 in 2018 and later in rhombohedral MoS2 bilayers.
Sliding ferroelectricity in 2D van der Waals stacks
Sliding ferroelectricity is ferroelectricity in 2D van der Waals stacks in which vertical polarization switches by in-plane layer sliding rather than ion displacement. It was proposed in 2017.
Sliding filament theory
Sliding filament theory: the 1954 Huxley–Niedergerke and Huxley–Hanson model of muscle contraction in which actin and myosin filaments slide past each other, shortening sarcomeres without filament length change, powered by ATP-driven myosin cross-bridges and triggered by calcium.
Sliding mode control
Sliding mode control (SMC) is a robust nonlinear control method that drives a system's state onto a prescribed sliding surface, making it insensitive to matched disturbances and model uncertainty.
Sliding mode observer
A sliding mode observer (SMO) is a state estimator, built on sliding mode control theory, that reconstructs a motor's back-EMF to estimate rotor position and speed without a sensor.
