This work is a scientific and philosophical treatise that geometrically and mechanically explains the workings of "mechanics" (mechanika), technologies designed to assist human needs against the natural course of events. The author posits that the principle of the "circle," which possesses contradictory properties, lies at the foundation of all mechanical movements, including those of scales and levers. In the first half, the author geometrically demonstrates how the principle of the lever can be reduced to circular motion, showing how distance from a fulcrum or the radius of a circle creates mechanical advantages. The middle section applies these principles to various practical devices and phenomena, such as ship rudders, oars, pulleys, wedges, dental forceps, and nutcrackers, illustrating how they all function based on the lever. In the latter half, the text tackles intriguing physical puzzles, including the famous "wheel paradox" of concentric circles, the motion of projectiles, the posture required for a person to stand up, and the behavior of objects in a whirlpool. Ultimately, the work stands as an inquiry that bridges abstract mathematical theory with physical reality, reducing the wonders of the world to fundamental mechanical principles.
