Area of Science:

  • Biological Sciences
  • Physics
  • Perception

Background:

  • Classical physics views time as continuous and absolute.
  • Biological systems exhibit time's cyclical nature through physiological periodicities.

Purpose of the Study:

  • To contrast the concept of time in classical physics with its nature in biological sciences.
  • To explain the 'granulation of time' and perception of movement in living organisms.

Main Methods:

  • Conceptual analysis comparing physical and biological time.
  • Explanation of temporal perception based on the duration of the present (DP).

Main Results:

  • Biological time is fundamentally cyclical, not continuous.
  • The duration of the present (DP) causes time granulation, enabling perception of movement.
  • This perception mechanism applies to both real-world and media-presented movement.

Conclusions:

  • Time perception in living beings differs significantly from classical physics.
  • Cyclical biological time and DP are key to understanding temporal perception and movement detection.
