Because Optics contributed a new dimension to the study of vision, it influenced later scientists. In particular, Ptolemy used Euclid's mathematical treatment of vision and his idea of a visual cone in combination with physical theories in Ptolemy's Optics, which has been called "one of the most important works on optics written before Newton". [3]
The early writers discussed here treated vision more as a geometrical than as a physical, physiological, or psychological problem. The first known author of a treatise on geometrical optics was the geometer Euclid (c. 325 BC–265 BC). Euclid began his study of optics as he began his study of geometry, with a set of self-evident axioms.
[2] [3] [4] Around 300 BC, Euclid wrote Optics and Catoptrics, in which he studied the properties of sight. Euclid postulated that the visual ray emitted from the eye travelled in straight lines, described the laws of reflection, and mathematically studied the appearance of objects by direct vision and by reflection.
Commentary on the Data of Euclid. This work is written at a relatively advanced level as Theon tends to shorten Euclid's proofs rather than amplify them. [2] Commentary on the Optics of Euclid. This elementary-level work is believed to consist of lecture notes compiled by a student of Theon. [2] Commentary on the Almagest.
In its first batch of full-color images, the Euclid telescope captured a cosmic portrait that officials at the space agency called “a revolution for astronomy.” The image shows roughly 1,000 ...
Seneca says that it can be used to read letters no matter how small or dim) [4] 4th century BC Mo Di first mentions the camera obscura, a pin-hole camera. 3rd century BC Euclid is the first to write about reflection and refraction and notes that light travels in straight lines [4] 3rd century BC – The Baghdad Battery is dated from this period.
