Archimedes' heat ray: is a device that Archimedes is purported to have used to burn attacking Roman ships during the Siege of Syracuse (c. 213–212 BC). It does not appear in the surviving works of Archimedes and is described by historians writing many years after the siege.

The Lower Paleolithic period lasted over 3 million years, during which there many human-like species evolved including toward the end of this period, Homo sapiens.The original divergence between humans and chimpanzees occurred 13 (), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being ...

It was so-named after the Greek mathematician Archimedes who first described it around 234 BC, although the device had been developed in Egypt earlier in the century. [ 2 ]
3rd century BC: Archimedes further develops the method of exhaustion into an early description of integration. [57] [58] 3rd century BC: Archimedes calculates tangents to non-trigonometric curves. [59] 3rd century BC: Archimedes uses the method of exhaustion to construct a strict inequality bounding the value of π within an interval of 0.002.
The siphon is a simple instrument; but the forcing-pump is a complicated invention, which could scarcely have been expected in the infancy of hydraulics. It was probably suggested to Ctesibius by the Egyptian wheel or Noria , which was common at that time, and which was a kind of chain pump, consisting of a number of earthen pots carried round ...
