On May 17, 1902, archaeologist Valerios Suisse discovered the oldest computer, the Antiquity Terra mechanism, used in ancient Greek times.
Valerios Stasis was a Greek archaeologist and one day he found a piece of rusty metal and found it was his first computer.
In celebration of the 115th anniversary of the discovery of the anti-key terrorism mechanism on the 17th, Google changed its main logo and commemorated "how rusty scrap metal can bring tremendous knowledge and inspiration."
This ancient machine was the first similar machine. The ancient Greeks used this machine to plot the movement of the sun as well as the movements of the moon and other planets, and they were also used to calculate both eclipses and lunar cycles.
The anti-key terra mechanism is an astronomical calculator that can perform some basic mathematical operations such as addition, subtraction, multiplication, and division.
This machine was able to juxtapose the lunar month and the year and could indicate where the sun and moon overlapped with the zodiacal arches.
The world's first computerized antikitera mechanism, made up of about 30 bronze cogs entangled in shoebox-sized trees and bronze boxes, was created around the second century BC.
