3D printing: Utilizes machines that receive instructions from a computer program to create physical items, including toys, food, and body parts. The program dictates where and how successive layers of raw material are placed to form a three-dimensional object.
angle: The measurement (usually in degrees) of the distance between two intersecting lines or planes at or near their point of intersection.
coil: Rings or spirals formed by wrapping wire or fibers around a core, or the shape created by such coils.
colleague: Someone who collaborates with others in a work environment, such as colleagues and team members.
pollutants: Undesirable or unnatural substances like chemicals, biological matter, or other materials present in the environment (water, soil, air, body, food, etc.). Some pollutants can be harmful depending on their concentration or accumulation in the body or the environment over time.
the current: A moving fluid like water or air with a discernible direction of flow.
engineering: The application of mathematics and science to solve practical problems, with individuals working in this field known as engineers.
fluid mechanics: The study of how fluids (liquids and gases) behave under various conditions and in response to external forces.
intestine: Informally refers to the gastrointestinal tract, particularly the intestines.
helix: A three-dimensional object, like a corkscrew or spiral staircase, formed by wrapping a single layer of wire evenly around a cylinder or cone.
mechanics: The study of the motion of objects.
vertical: Describing two objects that are perpendicular to each other, roughly at a 90-degree angle. For example, the top and bottom lines of the letter “T” are vertical to each other.
physicist: A scientist specializing in the study of matter and energy.
Proceedings of the National Academy of Sciences: A respected journal founded in 1914, publishing original scientific research across biology, physics, and social sciences. Each of the over 3,000 papers published annually undergoes thorough peer review and approval by members of the National Academy of Sciences.
resin: A sticky, sometimes fragrant substance often produced by plants, and the viscous starting material of certain plastics that hardens when heated or exposed to light.
shark: A predatory fish species that has existed in some form for millions of years, with a body structure primarily made of cartilage instead of bones. Sharks, along with skates and rays, fall under the category of elasmobranchs. They have slow growth and reproduction rates, with some species laying eggs and others giving birth to live young.
system: A network of components working together to perform a specific function, such as the circulatory system in the human body or the railway system of a country. Systems can also refer to processes and ideas organized in a methodical sequence to achieve a task.
valve: An apparatus that can regulate or stop the flow of gas or liquid through a passage, with certain specialized valves allowing flow in only one direction.
