Time theory

Explore the philosophy and physics behind how we measure an instant.

Philosophy & physics

Thought

From Aristotle’s “now” to Einstein’s relativity, time has been both a felt companion and a measurable parameter. Equally, every clock is an experiment in turning motion into a countable moment.

  • Mechanical clocks count oscillations; atomic clocks count quantum transitions.
  • Special relativity shows that simultaneity depends on observers’ motion—GPS satellites compensate for that.
  • Civil calendars reconcile continuous cosmic cycles with discrete days, using leap seconds or months.

Applying the theory

Practice

Keep time theory alive by documenting assumptions in your meetings—note which calendar, clock, and time zone you referenced so others can map your timeline back to their perspective.
