A workshop to construct a unique sundial.
In the present age and circumstances it seems inconceivable to use a sundial for telling time. Before the advent of railways, every city would have its own local time, since the sundial was the only source of telling time.
Sundials have been invented independently in every major culture and have become more accurate and sophisticated as cultures have developed. The largest sundial in the world, which is the Samrat Yantra of Jaipur, can tell time to an accuracy of 1 second. As the Earth turns on its polar axis, the sun appears to cross the sky from East to West, rising from beneath the horizon to a zenith at mid-day and falling again behind the horizon at sunset. Both the azimuth
(direction) and the altitude
(height) can be used to create time measuring devices.
The making of a sundial and improving its accuracy reveals the secrets of Earth’s rotation and revolution around the Sun. Would you like to learn these secrets?
As a part of Five Million Incidents Ajay Talwar
will be conducting a workshop to construct various types of sundials, such as: Horizontal, Vertical, Vertical Declining, Equatorial, Polar, Cube and more. Fifteen participants will be selected to attend the workshop and take home a sundial that they make during the workshop.
In 100-150 words, please tell us why you want to participate in this workshop.
