Everyone always has, and we still do. Now, in modern times, we have a machine designed to turn around once in exactly the same time as it takes the sun to turn around once in the sky. It has a thing on it to display what part of the cycle the sun is in. In order to be able to talk about it with other people, we place a standard set of marks all around the display-thing so we can refer to the number of marks, and the orher person knows what point in the cycle we're talking about. But the basic idea of the machine is to match the cycle of the sun. If my machine doesn't match the sun's daily motion pretty close, I have to quickly find another machine that's still running properly, or else I can refer back directly to the sun to get a rough idea of how many marks we're at. If I don't do one or the other pretty quick, I'm going to be early or late for all my appointments.

Where was the first sundial made and used?

Why did the Au is not used to measure distances on earth?
AU is not used to measure the distances on earth, because a astronomical unit is a unit of measurement equal to the distance between Earth and Sun. So that's why you cannot use Au for measure the distances on Earth.
What is difference between angstrom and astronomical unit?
An angstrom is a unit of length equal to one ten-billionth of a meter, commonly used to measure atomic distances. An astronomical unit is a unit of length based on the average distance between the Earth and the Sun, approximately 93 million miles, often used to measure distances within our solar system.
What is a sundial used for?
A sundial is a way to tell time without a clock. It uses the sun and positions of shadows to tell the time. These are fairly accurate.

What can one measure with a marine chronometer?
A marine chronometer measures time. It is a very precise instrument because it can also be used to measure the longitude of the ship at sea using the time shown and the angle of the sun.
