THE SCIENTIFIC TIME AND THE TIME OF COMMON SENSE

The scientific time is defined as the duration of things (between an interval) in a given physical state or situation. Day is divided precisely in 24 hours, hours in 60 minutes and minutes in 60 seconds. One hour of work is equal to one hour of rest.

The time of common sense is defined as the continuous succession of irreversible moments or changes that goes from the past to the future. This definition is correct, but emphasizes the details of time. The scientific definition of time is closer to the nature of this magnitude.

For common sense, time may go slower or faster according to people's emotional state. Also for common sense, time flows faster as we age. To affirm that time is what clocks measure is also an idea of common sense.

The change-interval duality is deduced from the scientific definition of time.
