compound: (usually used as a synonym for chemical) A compound is a substance fashioned when two or extra chemical components unite (bond) in mounted proportions. For instance, water is a compound made from two hydrogen atoms bonded to 1 oxygen atom. Its chemical image is H2O.
conducting: (in physics and engineering) The method or capability of some construction to direct a circulation by it of some present (particularly an electrical present).
conductor: (in physics and engineering) A cloth by which {an electrical} present can circulation.
present: A fluid — resembling of water or air — that strikes in a recognizable path. (in electrical energy) The circulation of electrical energy or the quantity of cost transferring by some materials over a selected time period.
knowledge: Information and/or statistics collected collectively for evaluation however not essentially organized in a approach that offers them which means. For digital data (the kind saved by computer systems), these knowledge usually are numbers saved in a binary code, portrayed as strings of zeros and ones.
electrical present: A circulation of electrical cost — electrical energy — often from the motion of negatively charged particles, known as electrons.
electrical energy: A circulation of cost, often from the motion of negatively charged particles, known as electrons.
electron: A negatively charged particle, often discovered orbiting the outer areas of an atom; additionally, the service of electrical energy inside solids.
electronics: Gadgets which can be powered by electrical energy however whose properties are managed by the semiconductors or different circuitry that channel or gate the motion of electrical fees.
factor: A constructing block of some bigger construction. (in chemistry) Every of multiple hundred substances for which the smallest unit of every is a single atom. Examples embody hydrogen, oxygen, carbon, lithium and uranium.
subject: (in physics) A area in area the place sure bodily results function, resembling magnetism (created by a magnetic subject), gravity (by a gravitational subject), mass (by a Higgs subject) or electrical energy (by {an electrical} subject).
friction: The resistance that one floor or object encounters when transferring over or by one other materials (resembling a fluid or a fuel). Friction usually causes a heating, which might harm a floor of some materials because it rubs towards one other.
lead: A poisonous heavy steel (abbreviated as Pb) that within the physique strikes to the place calcium desires to go (resembling bones and enamel). The steel is especially poisonous to the mind. In a baby’s growing mind, it could completely impair IQ, even at comparatively low ranges.
levitation: The act of suspending or inflicting to drift in air an individual or object — seemingly in violation of gravity.
magnet: A cloth that often comprises iron and whose atoms are organized in order that they appeal to sure metals.
magnetic subject: An space of affect created by sure supplies, known as magnets, or by the motion of electrical fees.
mercury: Typically known as quicksilver, mercury is a component with the atomic quantity 80. At room temperature, this silvery steel is a liquid. Mercury can also be very poisonous.
steel: One thing that conducts electrical energy effectively, tends to be shiny (reflective) and is malleable (which means it may be reshaped with warmth and never an excessive amount of pressure or strain).
MRI: Quick for magnetic resonance imaging. It is an imaging method to visualise gentle, inner organs, just like the mind, muscle tissue, coronary heart and cancerous tumors. MRI makes use of robust magnetic fields to document the exercise of particular person atoms.
particle: A minute quantity of one thing.
quantum: (pl. quanta) A time period that refers back to the smallest quantity of something, particularly of power or subatomic mass.
qubit: Quick for quantum bit. It is the analog of a bit — a zero or one — in classical computing. Classical computer systems encode knowledge as bits, the place every of those is both a zero or one. In quantum computing, knowledge as a substitute are encoded as qubits, the place the 2 fundamental states are often written as ∣0⟩∣0⟩ and ∣1⟩∣1⟩. A qubit may be in state ∣0⟩∣0⟩, ∣1⟩∣1⟩. However in contrast to a classical bit, a qubit additionally may be in a so-called linear mixture of each states. The identify of this phenomenon is superposition.
resistance: (in physics) One thing that retains a bodily materials (resembling a block of wooden, circulation of water or air) from transferring freely, often as a result of it supplies friction to impede its movement.
superconductor: Supplies that haven’t any resistance to the circulation of electrical energy, usually solely when they’re cooled under a sure temperature. Superconductors additionally repel all magnetic fields, which permits them to drift within the air when they’re positioned inside a powerful magnetic subject.
tumor: A mass of cells characterised by atypical and sometimes uncontrolled progress. Benign tumors won’t unfold; they simply develop and trigger issues in the event that they press towards or tighten round wholesome tissue. Malignant tumors will finally shed cells that may seed the physique with new tumors. Malignant tumors are also called cancers.
unit: (in measurements) A unit of measurement is an ordinary approach of expressing a bodily amount. Items of measure present context for what numerical values symbolize and so convey the magnitude of bodily properties. Examples embody inches, kilograms, ohms, gauss, decibels, kelvins and nanoseconds.
