An abacus is a manual counting tool with sliding beads used for performing arithmetic calculations through tactile, visual number manipulation.

A unit of electric current in the centimetre–gram–second electromagnetic units (CGS‑EMU) system, equal to 10 amperes, representing high‑intensity electromagnetic flow.

Provides ready‑made backend infrastructure—databases, authentication, APIs, storage, and server logic—so developers can build apps faster without managing servers.

A soft, low‑friction metal alloy used to line bearings, reducing wear and allowing smooth mechanical movement.

A large, solid structure built from the shore out into the sea to protect a harbour or beach from the force of waves.

A daemon is an autonomous, persistent background agent—digital or symbolic—that performs ongoing tasks, monitors systems, or triggers actions without requiring active oversight.

The process of transforming raw, messy, or unstructured data into clean, structured, and usable formats suitable for analysis or downstream tasks.

An electronic device that heats a liquid into vapour for inhalation, often containing nicotine, flavourings, and additives, used as an alternative to traditional smoking.

ETL (extract, transform, load) is data integration process involving extraction, transformation, and loading of data into a unified destination.

A foundational functional layer that supports core operations, enabling structure, stability, and interaction across a system’s architecture.

A mathematical symbol (∇) used in vector calculus to denote the del operator, performing operations like gradient, divergence, and curl.

A traditional coastal net fishing method from the Solway Firth, where fishers stand in tidal waters using large, framed nets to catch salmon and sea trout.

A mathematical function with abrupt step-like changes, foundational in wavelet analysis for signal decomposition and measurement.

A formal early programming language created to express algebraic procedures with precise symbolic structure and machine readable logic.

A structural steel beam shaped like a capital “I,” engineered to carry heavy loads with high strength and minimal material, commonly used in construction and architectural frameworks.

A meaningful link between identifiers, accounts, or representations that establishes their relation to the same underlying entity.

A visual language that records human movement using symbols for direction, level, timing, and dynamics, enabling accurate documentation and reconstruction of choreography.

An extrinsic semiconductor doped with pentavalent atoms that donate free electrons, making electrons the majority charge carriers.

Software systems that detect, measure, and interpret a user’s emotional state during digital interactions.
