Quadrimechanica "Motion:observation and detection"
  Classical, Quantum and Relativistic mechanics elect time and space as fundamentals, extracting the measure of motion -velocity- from this static space-time platform. Conversely, the timelessness of Statistical mechanics computes the physical flow as an evolution of (dynamical) states which, at the end, comes to be what would be denoted as time. Moreover, the general structure of mechanics is such that the notion of observability is mixed up with that of measurability. In such a context, ignoring the distinction between "observable entities" and "measurable quantities", and projecting dynamical objects on a static background, the measured value of physical entities is taken as the true or real value of the entity. This contribution emphasises this distinction, correlating the concepts of "real values" and "experimental values" and indicating that motion is always underestimated in the spatiotemporal platform; following a gauge transformation, an argument centred on measurability favours a relational "non-relativistic" formulation, with potentially analogous predictions.
