mechanics
The branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles.
The straightforward or easy-to-understand workings of something.
The fundamental principles or simplest workings of a system or process.
Similar to complex, emphasizing the difficulty and number of interconnected parts in a system.
Refers to the intricate or detailed workings of a system, often requiring specialized knowledge to understand.
The set of physical laws describing the motion of bodies under the action of a system of forces, predating quantum mechanics.
The principles of mechanics based on Newton's laws of motion; essentially the same as classical mechanics.
The real, practical details of how something is done, as opposed to the theory.
The branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas).
The branch of physics that uses statistical methods and probability theory to explain the macroscopic behavior of a system.
The branch of astronomy that deals with the motion of celestial objects.
