Clickspring – Recreating the ancient engineering that built the Antikythera Mechanism

An evening pause: For background, the Antikythera Mechanism is an archaeological artifact from ancient Greece:

The Antikythera Mechanism is the oldest known scientific computer, built in Greece at around 100 BCE. Lost for 2000 years, it was recovered from a shipwreck in 1901. But not until a century later was its purpose understood: an astronomical clock that determines the positions of celestial bodies with extraordinary precision.

Today’s pause shows how this very complex mechanism, that includes many metal gears, might have been made by hand, without electricity and our modern tools.

An evening pause: Watch another demonstration of Galileo’s Leaning Tower of Pisa experiment where he proved gravity worked the same on all objects regardless of weight.

May everyone have a great weekend.
