application: A particular use or function of something.
circuit: A network that transmits electrical signals. In the body, nerve cells create circuits that relay electrical signals to the brain. In electronics, wires typically route those signals to activate some mechanical, computational or other function.
computer model: A program that runs on a computer that creates a model, or simulation, of a real-world feature, phenomenon or event.
fabric: Any flexible material that is woven, knitted or can be fused into a sheet by heat or compression and drying.
metal: Something that conducts electricity well, tends to be shiny (reflective) and is malleable (meaning it can be reshaped with heat and not too much force or pressure).
metamaterial: Lab-built materials that develop particularly desirable properties based on the way that they are built, rather than what they’re made from. They have qualities not found in the natural world.
model: A simulation of a real-world event (usually using a computer) that has been developed to predict one or more likely outcomes. Or an individual that is meant to display how something would work in or look on others.
nanometer: A billionth of a meter. It’s such a small unit that researchers use it as a yardstick for measuring wavelengths of light or distances within molecules. For perspective, an average human hair is about 60,000 nanometers wide.
nanoparticle: A small particle with dimensions measured in billionths of a meter.
particle: A minute amount of something.
radar: A system for calculating the position, distance or other important characteristic of a distant object. It works by sending out periodic radio waves that bounce off of the object and then measuring how long it takes that bounced signal to return. Radar can detect moving objects, like airplanes. It also can be used to map the shape of land — even land covered by ice.
simulation: (v. simulate) An analysis, often made using a computer, of some conditions, functions or appearance of a physical system. A computer program would do this by using mathematical operations that can describe the system and how it might change over time or in response to different anticipated situations.
stencil: A picture or pattern that is created by temporarily holding a shape or cutout against a surface and then applying some paint or pigment along the internal or external edges of that shape or cutout. If paint is applied along the outside edges, the surface will depict the unpainted shape of the object, with sharply defined, clean internal edges. If a cutout is used, the painted shape will depict the pattern of the cutout, with sharply defined, clean external edges.
technology: The application of scientific knowledge for practical purposes, or the devices, processes and systems that result from those efforts.
