01 / Overview

The ancient Greek geographer Eratosthenes combined astronomy and geodesy, and was the first to propose the idea of observing the position of the sun simultaneously in two places on the summer solstice. Based on the difference in the length of the shadows of the earth's surface, he studied and analyzed it, and thus summarized the scientific method of calculating the circumference of the earth, known as the "father of geography". In addition, the concept of latitude and longitude was also first proposed by him.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
