What is the similarity and difference in the concept used in ancient and modern measuring devices?
Dear student,
Please find below the answer:
The concepts related to measuring devices in ancient and modern times have no similarity. The only thing in common was the aim to measure different quantities like weight, time, speed etc. By taking the example of measuring devices for time, the differences are as follows:
Given below are examples of time measuring devices used in ancient times. They work on a different principle:
1) Sand-glass which made up of two conical glass connected vertically by the narrow neck. It could measure the passage of specific time period depending upon the size and width of the glass and the quantity of sand in it. It measured time more accurate than the water clock or a candle clock.
2) The water clock was also used to measure time observing the steady flow of water from or into a container. Measurements were marked on the container but there were variations due to the pressure of water flow.
3) Candle clock, in it candle was marked with numbers and the burning of wax indicated a specific period of time.
Modern devices include clock and wristwatch. These two devices move 360 degrees in a day to show time.
Regards.
