Chapter 15, Problem 15.1EAA

To determine

The primitive and modern definitions of time. Also, which is more accurate

Expert Solution & Answer

Explanation of Solution

Given Information:

Required information on primitive and modern definitions of time is provided in the question. Also, provided is the required information on which is more accurate.

In the bygone days, time was measured by the following of the shadow of the individual. Even today, in some remote areas this is still practiced. The shadow of the individual changed as the day proceeded with no shadow appearing at noon. In the villages, while working in the fields this was the practice of judging for them to attend their daily chores. The setting of the sun and the arrival of the moon was also an indication for the people to return home along with their livestock. There was no other method for the people in the villages and the upper hill regions to understand the day’s progress. However, this is not the scientific way of calculating the time interval. An example would be for steamers on the seas where this method cannot be practiced.

An improvement on judging the time with reference to the shadow was the pendulum clock and later the quartz clock which provided nearly good timings for day to day activities. However, this accuracy was not sufficient for certain activities like flight, missile launching and space travel etc.

Hence, the timing mechanism had to be more accurate and specific accounting for the location also. To get an accurate time counting, they came up with the atomic clock solution. An atomic clock was based from a particular point and accepted internationally-GMT. The atomic clock timings are used for a missile, space launches etc. This way the time counting mechanism evolved.

Conclusion:

The above-cited way shows how the time counting mechanism evolved over time. Modern definition of time is more accurate as compare to primitive definition of time.
