What two practical disadvantages of sundials compared with clocks?
A sundial doesn't work at night
A sundial doesn't work when the sun is hidden - by clouds, buildings, etc.
A sundial only works at the latitude it is designed for - a sundial built for Ecuador woudl not be accurate in New Zealand.
Clocks are made to rotate that way. The clock face is modeled after the sun dial, a more primitive way to track time throughout the day. Prior to the invention of mechanical clocks, sundials were used to tell time. In the northern hemisphere, the sun's shadow moves around a sundial in a clockwise arc. Mechanical clock dials emulate this motion. Had clocks and sundials been developed first in the southern hemisphere, clocks would go counter-clockwise…
There are a lot of clocks that have Roman numerals---not JUST churches. Originally it may have been a continuation of the archaic designs of sundials. Many clocks today have Roman numerals because it makes them look old and classy. Also some clocks with Roman Numerals will have the 4 written as "IV" and some as "IIII". This odd dichotomy has no firm explanation.
There were clocks and watches in the 1800s. Watches then were bulky compared to the ones today, and you would carry them in your pocket. They were powered by a metal spring, and you would have to wind them to keep them running. Clocks of the day generally had pendulums that would swing to keep the time. They also had to be wound about once a day. Some had a spring. Winding would coil up…
Egyptians invented a lot of things! Paper was one and lock's and clocks! Yes clocks but not the electronic ones! we now call the sundials.. They invented makeup and medicine but it wasn't very nice, later it was made from crushed mummy dug up 100 years later!! Egyptians invented a tool called shadoof. this helped them move and carry water from the river Nile!
The clock is one of the oldest human inventions. Water clocks, also known as clepsydrae along with the sundials, are possibly the oldest time-measuring instruments. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon and in Egypt around the 16th century BC. However, it is believed that water clocks appeared as early as 4000 BC in India and China.
The sun doesn't effect time, but the Earth's rotation (and the sun's apparent position) sets what we think of as time. After all, a clock is nothing but a mechanical sundial and clocks turn clockwise because sundials (in the northern hemisphere) turn clockwise ... because the Earth turns counterclockwise.
