Clocks

Clocks were invented in different parts of the world, but it was 
the Egyptians that introduced the concept. The most popular one is probably 
the sun clock where the shadow made by the sun is used to judge what time of 
day it is. You’ve probably heard of them before as obelisksö.

But what happens if the sun is gone? That’s where the water clock comes in. 
The Ancient Egyptians created them to tell time at night. It works like an 
hourglass where water drips down at a predictable rate and time is told 
depending on the level of liquid. The invention of the clock also gave way to 
other inventions such as the 365-day calendar we use today and even the 
concept of leap years.
