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 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 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.
Sliding puzzle
Sliding puzzle: pieces slide into an empty space without lifting or rotating. Covers the 15 puzzle (Chapman, 1874; 1880 craze), Klotski/Huarong Dao, Rush Hour (Yoshigahara, 1996), parity solvability, and PSPACE-completeness.
Sliding stability analysis
Sliding stability analysis checks whether a concrete gravity dam has enough shear resistance along a potential failure plane to resist horizontal forces from water pressure and uplift.
Sliding window protocol
A sliding window protocol is a method of reliable data transmission in which a sender may send a limited window of data before acknowledgements arrive; it underlies TCP flow control.
Sliding-window attention
Sliding-window attention (SWA) is an attention scheme in which each transformer token attends only to the previous w tokens, cutting per-token memory from O(S) to O(w).
Slido
Slido is a web-based audience interaction platform, owned by Cisco, where participants in meetings, lectures, and events submit questions, vote in live polls, and take quizzes without installing an app.
