Capacitor is an electrical component that stores energy in an electric field, typically by separating electric charges in two plates separated by a dielectric. It regulates voltage, filters signals, and shapes transient responses in circuits. In everyday electronics, capacitors come in many sizes and types, including ceramic, electrolytic, and tantalum.

Chaos (noun): a complete lack of order or predictability, often resulting in confusion or disorder. It denotes a state where elements are misaligned or in flux, making outcomes uncertain. Used in various contexts from science to everyday talk to describe turbulent situations or environments.

Chi is a noun borrowed from Greek meaning the letter X and, in some contexts, a syllable or sound used in various proper names and terms. In contemporary English, it commonly denotes the Greek letter chi, or is encountered in religious, cultural, or martial-arts contexts. The pronunciation /kaɪ/ treats it as two letters forming a single-syllable diphthongal word, often used in transliteration and borrowed phrases.

Coherence is the quality of being logical, consistent, and well-organized, ensuring that all parts of a message fit together and support a clear overall meaning. It typically refers to ideas, arguments, or narrative flow that connect smoothly from one point to the next. In academic and communication contexts, coherence aids reader and listener comprehension by maintaining structure and unity.

Constant describes something that remains steady or unchanged over time, or a mathematical value that does not vary. In everyday use, it can refer to a fixed condition, a reliable attribute, or a constant in equations. The word conveys continuity, permanence, and regularity in both tangible and abstract contexts.

Continuum (n.) a continuous sequence or range in which elements are not discrete but form an unbroken whole. It denotes a progression or spectrum linking extremes, often used in science, philosophy, and daily discussion to describe gradual change without clear boundaries. The term implies compatibility and interconnectedness across a series or scale.

Corona is a two-syllable noun primarily referring to a crown or circular ring worn as a headpiece; in modern usage it also denotes the coronavirus or a period of peak airborne disease statistics. In astronomy, it simply means the outermost part of the sun’s atmosphere. The term can appear in medical, cultural, and meteorological contexts, often with formal or technical tone.

Curvature is the degree to which something is curved or bent, or the shape formed by bending. It often refers to the geometric property of an arc or the deviation from straightness in an object. In mathematics, curvature describes how a curve deviates from a straight line, with specific measures in differential geometry.

Delta is a noun meaning a broad, fan-shaped area of fertile land at the mouth of a river, formed from sediment deposits. It can also refer to a shape (the Greek letter Δ) or to a landform created where a river splits and slows as it enters a larger body of water. In science and business, it denotes change or difference, often shown as a difference in measurements.

Diffraction is the bending and spreading of waves, such as light or sound, when they encounter an obstacle or pass through a narrow aperture. This phenomenon causes interference patterns and changes in intensity. In physics, diffraction helps explain why waves don’t travel in perfectly straight lines and how they can produce fringes or spreading beyond obstacles.

Diffusion is the process by which something spreads or dissuses through a medium or substance due to random motion and collisions of particles. It commonly refers to the spread of molecules, gases, or innovations in a system, driven by concentration differences or uniform distribution over time. In science, diffusion describes how compounds move from regions of higher to lower concentration, eventually reaching equilibrium.

ETA is a noun that, in everyday use, typically abbreviates estimated time of arrival. In specialized contexts it can denote a terrorist organization or a brand/organization acronym. The term is usually pronounced as individual letters or as a two-syllable acronym, depending on context, with stress often on the middle/second vowel sound when read as a word-like abbreviation.

Emission is the act or process of releasing something, such as light, gas, or signals, from a source. In science and industry it often refers to the discharge or radiating of energy or particles. The term can also describe a broadcast or transmission, especially of signals or information.

Enthalpy is a thermodynamic property representing the total heat content of a system, equal to its internal energy plus the product of its pressure and volume. In practical terms, it quantifies the heat transfer under constant pressure. The term is used mainly in chemistry and physics to analyze energy changes in reactions and phase transitions.
