Vision
See and to be seen.
Ben Jonson, Epithalamion, Stanza 3, line 4. Oliver Goldsmith, Children of the World, Letter 71.
Vision
Not so many years ago this was a mistake that brain scientists actually made: they succumbed all too often to the temptation to treat vision as if it were television — as if it were simply a matter of getting "the picture" from the eyes to the screen somewhere in the middle where it could be handsomely reproduced so that the phenomena of appreciation and analysis could then get underway. Today we realize that the analysis — the whatever you want to call it that composes, in the end, all the visual understanding — begins right away, on the retina; if you postpone consideration of it, you misdescribe how vision works.
Daniel C. Dennett, "Facing Backwards on the Problem of Consciousness" Journal of Consciousness Studies, 3 (1), 1996, pp. 4-6.
Vision
The Greeks elaborated several theories of vision. According to the Pythagoreans, Democritus, and others vision is caused by the projection of particles from the object seen, into the pupil of the eye. On the other hand Empedocles, the Platonists, and Euclid held the strange doctrine of ocular beams, according to which the eye itself sends out something which causes sight as soon as it meets something else emanated by the object.
Florian Cajori, A History of Physics in its Elementary Branches (1899)
In June 1770, the explorer James Cook ran aground on the Great Barrier Reef in Australia and became the first European to experience the world's largest coral reef, today a paradise for scientists and holidaymakers alike. Last year, the James Cook research vessel set out to encounter unique and unexplored corals, this time in the deep ocean. Led by ERC grantee Dr Laura Robinson (University of Bristol, UK), the team on board crossed the equatorial Atlantic to take samples of deep-sea corals, reaching depths of thousands of meters. On the expedition, Dr Robinson collected samples that are shedding light on past climate changes and she will share her findings at TEDx Brussels.
