Why this is here: Su Song, a Chinese engineer, built a 12-meter-high hydro-mechanical astronomical clock tower in 1088 AD, using gears and automation centuries before similar technology appeared in Europe.

Archaeologists in the Lebombo Mountains between South Africa and Eswatini discovered the 44,000-year-old Lebombo Bone. The fibula bone, with 29 notches, likely functioned as a counting device or early lunar calendar. Around 12,000 years ago, structures at Göbekli Tepe in Turkey suggest early calendar use, while sites like Newgrange and Stonehenge show alignment with solstices roughly 5,000 years ago.

The Egyptians and Sumerians both created 12-month calendars, with the Egyptians arriving at a 365-day year. Roman calendars drifted by as much as 90 days, prompting Julius Caesar to enact a confusing 445-day year to reset it. Pope Gregory XIII later refined this system, deleting 10 days in 1582 to establish the Gregorian Calendar still in use today.

Despite advances, reconciling Einstein’s relativity with quantum mechanics remains unsolved, leading some physicists to question the nature of time itself. The pursuit of understanding time continues with ongoing research.
