Mechanical analogy for the wave-particle: helix on a vortex filament
... The remarkable feature of this phenomenon is that the motion of the hump is owing to the rotation of an individual helix with the angular velocity ντ 2 but not because of its longitudinal motion. This is the effect of a screw! A bolt is screwed into a nut due to rotation. In general, the velocity υ ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
