Top Tweets for #Refracted
Descartes argued that vision is a physical process, not dependent on Aristotelian “intentional species” (immaterial forms transmitted from objects to the eye which I have spoken on).
He claimed that light rays from objects enter the eye through the pupil, are #refracted by the #lens, and project an inverted image on the retina, which the optic nerve then conveys to the brain.
He clarified that the mind does not directly perceive the retinal image as if there were “other eyes in our brain.”
Instead, the brain interprets the patterns of light on the retina to form a coherent perception, emphasizing a separation between physical #optics and cognitive processing.
READ #ReneDescartes 'La Dioptrique' (1637) at Internet Archive and see his illustration of the human eye - Camera Obscura comparison on p36 here

Decartes's 1637 diagram below of the eye as a Camera Obscura. Descartes compared the #eye to the #camera saying that the retina is the same as where the image resides.
On p76 of his 'Magia Universalis,' Kaspar Schott used the same analogy.
NOT FOR THE WEAK OF HEART
To illustrate his theory, Descartes proposed a striking experiment: take the eye of a recently deceased person (or, if unavailable, an #ox or another large animal), remove the membranes at the back to expose the retina, and place the eye in the hole of a #CameraObscura. By scraping away the flesh until the retina is visible, one could observe the inverted image of external objects projected onto the retina.
This experiment aimed to show that the eye operates as an optical instrument, with the #retina acting as a screen where light forms an inverted image, following principles established by #JohannesKepler, who localized sensory images on the retina rather than the lens.

Look at this lotus leaf’s shadow, it looks nothing like the actual leaf and this is due to the #MeniscusEffect,
Structures on the leaf distorted the surface tension creating many lenses through which light is #refracted.

They involve stories and their tellers.

As TVL on @prism_protocol continues to increase, more & more projects within the @terra_money ecosystem are recognizing the win-win situation for cross-protocol integrations of #refracted assets.
SPHERICAL LENS
This diagram (below) of a water-filled spherical lens shows light being #refracted. It’s from Roger Bacon's ‘De multiplicatione specierum’. Image taken from A.C. Crombie's 'Robert Grosseteste and the Origins of Experimental Science’, and identified as Figure 2.

Caught a nice moment of some Rare rays dancing on the ceiling. Not exactly Blade Runner levels of caustics but pleasantly soothing non the less 😌 #Reflected #Refracted #Light
@Bluedre72692262 @PeaceMongerWV @bendercock I'd suggest Tian et al underestimated how much heat gets trapped by #clouds of the smaller #sulphuric/water drops and/or how much heat is released by cities (its vast); and overestimated the amount of light that gets #refracted back into space.
