There isn't anywhere that lists an exact date for the discovery of the Archimedes Principle. The closest that could be found was that the special event occurred some time 2200 years ago somewhere between 287 BC and 212 BC.
"Were"? Location: Perigord area, France. Discovered: 1940. Some debate (according to a French W.pedia entry) on actual date.
The concept of volume has been understood for thousands of years, with early civilizations such as the Mesopotamians and Egyptians using basic measurements to quantify volume. The specific term "volume" as a mathematical concept likely evolved over time, with contributions from ancient Greeks like Archimedes and further refinement during the Renaissance period.
It was discovered in 1898.
The origins of geometry are so unclear that no single individual can be credited with the "discovery" of this branch of mathematics. That said, we can cite the names of a number of early investigators who made major contributions, beginning with Euclid.Certainly it is broadly accepted that Euclid, the Greek mathematician, got the ball rolling with his Elements, which was penned circa 300 BC. This cornerstone volume gathered ideas and provided structure to what was then geometry. But manuscripts and writings dealing with geometry have been discovered, and date further back than Euclid. It could be argued that geometric ideas arose at the time formal writing developed. Use the link below to get an overview of the history of geometry.
