composite: (often used as a synonym for chemistry) A compound is a substance formed by combining two or more chemical elements in certain proportions. For example, water is a compound formed by combining two hydrogen atoms and one oxygen atom. Its chemical symbol is H2O.
command: (in physics and engineering) The process or ability to direct the flow of some current (especially electric current) through some structure.
conductor: (in physics and engineering) A material through which an electric current can flow.
the current: A fluid, such as water or air, that moves in a discernible direction. (In electricity) The flow of electricity or the amount of charge that passes through some material over a particular period of time.
data: Facts or statistics collected for analysis, but not necessarily organized in a meaningful way. In the case of digital information (the type stored in a computer), these data are usually numbers stored in binary code, represented as a string of 0s and 1s.
CurrentThe flow of electric charge (electricity), usually caused by the movement of negatively charged particles called electrons.
electricity: A flow of electric charge, usually caused by the movement of negatively charged particles called electrons.
Electronic: Negatively charged particles that usually orbit the outer regions of atoms and are also carriers of electricity in solids.
electronics: A device that is electrically powered but whose properties are controlled by semiconductors or other circuits that direct or control the movement of electric charges.
element: A building block of a larger structure. (In chemistry) Any of over 100 substances whose smallest unit is a single atom. Examples include hydrogen, oxygen, carbon, lithium, and uranium.
Field: (in physics) A region in space where certain physical effects act, such as magnetism (produced by magnetic fields), gravity (produced by gravitational fields), mass (produced by the Higgs field), and electricity (produced by electric fields).
frictionFriction: The resistance encountered when a surface or object moves over or through another substance (such as a liquid or gas). Friction generally causes heating and can damage the surface of one substance as it rubs against another.
lead: A toxic heavy metal (Pb for short) that migrates to places in the body where calcium wants to go (like bones and teeth). This metal is especially toxic to the brain. Even relatively low levels in a child’s developing brain can permanently impair IQ.
Levitation: The act of making a person or object levitate or suspend in the air as if in defying gravity.
magnet: A substance that usually contains iron, whose atoms are arranged in such a way that they attract certain metals.
magnetic fieldA field of influence created by certain substances called magnets, or by the movement of electric charges.
MercuryMercury, also known as quicksilver, is an element with atomic number 80. At room temperature, this silvery metal is liquid. Mercury is also highly toxic.
metal: Something that conducts electricity well, is shiny (reflective), and malleable (i.e. can be reshaped with heat and without excessive force or pressure).
MRI: Short for magnetic resonance imaging. It is an imaging technique that visualizes soft internal organs such as the brain, muscles, heart, and cancerous tumors. MRI uses a strong magnetic field to record the activity of individual atoms.
particle: A trace of something.
quantum: (plural quanta) A term referring to the smallest amount of something, especially energy or subatomic mass.
Quantum Bits: Short for qubit, which is equivalent to a bit (0 or 1) in classical computing. Classical computers encode data as bits, where each bit is either 0 or 1. In quantum computing, data is encoded as qubits, with two basic states usually written as ∣0⟩∣0⟩ and ∣1⟩∣1⟩. A qubit can be in the states ∣0⟩∣0⟩, ∣1⟩∣1⟩. However, unlike classical bits, a qubit can also be in what is called a linear combination of both states. The name for this phenomenon is superposition.
resistance: (in physics) Something that prevents a physical material (such as a block of wood or a stream of water or air) from moving freely, usually by friction.
Superconductors: A material that offers no resistance to the flow of electricity, usually only resisting it when cooled below a certain temperature. Superconductors also repel all magnetic fields, allowing them to levitate when placed in a strong magnetic field.
tumor: A mass of cells characterized by atypical and often uncontrollable growth. Benign tumors don’t spread; they just grow and cause problems by squeezing or pinching healthy tissue. Malignant tumors eventually shed cells that can seed new tumors in the body. Malignant tumors are also known as cancer.
unit: (In measurement) A unit of measurement is a standard way of expressing a physical quantity. A unit of measurement provides context for what a number represents and conveys the magnitude of a physical property. Examples include inches, kilograms, ohms, gauss, decibels, kelvin, and nanoseconds.
