Dynamic Mechanicism

A philosophical worldview that sees the entire universe—including living beings, societies, and even thoughts—as fundamentally mechanical systems in motion. It's the belief that everything can ultimately be explained by the dynamic interactions of parts obeying physical laws. Dynamic mechanicism is the intellectual descendant of Newton and Laplace: the clockwork universe view, where free will is an illusion, consciousness is an emergent property of neural dynamics, and even love is just a particularly complex set of mechanical interactions.

Example: "He talked about relationships in terms of forces and reactions—a thoroughgoing dynamic mechanicism that left no room for mystery or magic."

Mechanical Dynamism

A philosophical or qualitative term describing the inherent tendency of mechanical systems to change, move, evolve, or exhibit complex behavior over time. It's not a formal branch of physics but a way of talking about machines as if they had a kind of life or spirit of motion. A clock has mechanical dynamism in its ticking, a engine in its cycling, a ecosystem in its flows. It captures the sense that even dead matter, when arranged into mechanisms, can produce surprisingly lively and unpredictable patterns of behavior.

Example: "Watching the antique clockwork automata dance, you couldn't help but feel the mechanical dynamism—gears and springs somehow brought to life."

Mechanical Dynamics

A near-synonym for dynamic mechanics, but with a subtle emphasis on the mechanical systems themselves rather than the abstract principles. Mechanical dynamics is the engineer's term: it's the study of how real, physical machines—gears, linkages, pistons, robots—behave under loads and motions. It includes vibration analysis, mechanism design, and the practical application of dynamic principles to ensure that things don't shake themselves apart when they move. It's dynamic mechanics with grease on its hands.

Example: "The bridge collapsed because the mechanical dynamics weren't properly modeled—they didn't account for the resonant frequencies that wind would excite."

Dynamic Mechanics

The branch of mechanics concerned with the relationship between motion and the forces that affect it—essentially, what most people simply call "dynamics." It's the study of how objects move when forces are applied, encompassing everything from a falling apple to a rocket launch. Dynamic mechanics asks: given these forces, what will the motion be? Given this motion, what forces must have caused it? It's Newton's laws in action, the physics of why things go where they go when pushed, pulled, or thrown.

Example: "The roller coaster designer lives and breathes dynamic mechanics—every loop, drop, and bank is calculated to keep the forces on your body survivable while maximizing thrill."

Negative Physics

A conceptual framework for describing physical quantities that can take on negative values in meaningful ways, beyond just mathematical convenience. Negative energy densities (predicted by quantum field theory), negative temperatures (achieved in laser systems), negative pressure (driving cosmic inflation), and negative mass (hypothetical) all fall under negative physics. It's the study of the physical regimes where our intuitive sense that "more" means "bigger positive number" breaks down, and the universe reveals stranger possibilities.

Example: "The Casimir effect proves negative energy densities are real—a genuine phenomenon of negative physics where empty space has less than zero energy between two plates."

Anti-Physics

A broad term for any proposed physical framework that would systematically oppose or invert the known laws of physics. Unlike specific branches like anti-gravity (which opposes one force), anti-physics imagines wholesale replacement of physical law: anti-matter behaving opposite to matter in every way (not just charge), anti-entropy being the default, anti-inertia governing motion. It's the physics of mirror universes, of worlds where up is down, attraction is repulsion, and every "law" we depend on is systematically violated.

Example: "The novel's alternate dimension operated on anti-physics—light bent away from massive objects, friction accelerated things, and nothing made sense by our standards."

Retrophysics

The umbrella term for any branch of physics that describes phenomena as they would appear if time ran backward. It encompasses retrothermodynamics, retromechanics, retroentropy—the whole suite of physical laws operating in reverse chronological order. Retrophysics is a powerful tool for thought experiments, helping physicists understand why certain processes are irreversible even when the underlying equations are time-symmetric. It's the physics of the rewound tape, the universe played backward, the cosmic movie running from credits to opening scene.

Example: "The professor assigned a retrophysics problem: calculate what the solar system would look like if we ran the equations backward for a billion years."
