The Ancient Engineers: An Astonishing Look Back... -

Ancient engineering feats, such as the 800-ton stones at Baalbek and the 2,000-year-old Antikythera Mechanism, demonstrate that complex engineering and precision were not modern inventions. Techniques like using volcanic ash for enduring Roman concrete and mortarless, earthquake-resistant Incan stonework reveal a profound, long-lasting grasp of physics and materials science.
