Now that I have a mental model for 3D shapes (not a visual perception from the eyes, but an inner representation that I can imagine/handle as volumes instead of as pictures/lines) I can better understand how not straightforward it is to "draw what you see"

to the point that I have to consciously switch between modes, and get (back) to the flattened perception to be able to draw as I am used to

Ants use a genetic 'bulldozer' to achieve a hyper-specific sense of smell

Ants have evolved an acute sense of smell, which requires each sensory neuron to choose one scent receptor out of hundreds. In a new study published in Nature, researchers at New York University have discovered what ants use to solve this biological puzzle: a self-regulating system in which choosing one gene physically silences all its neighbors.

A quotation from Marcus Aurelius

If you suffer distress because of some external cause, it is not the thing itself that troubles you but your judgment on it, and it is within your power to cancel that judgment at any moment.
 
[Εἰ μὲν διά τι τῶν ἐκτὸς λυπῇ, οὐκ ἐκεῖνό σοι ἐνοχλεῖ, ἀλλὰ τὸ σὸν περὶ αὐτοῦ κρῖμα, τοῦτο δὲ ἤδη ἐξαλεῖψαι ἐπὶ σοί ἐστιν.]

Marcus Aurelius (AD 121-180) Roman emperor (161-180), Stoic philosopher
Meditations [To Himself; Τὰ εἰς ἑαυτόν], Book 8, ch. 47 (8.47) (AD 161-180) [tr. Hard (1997 ed.)]

Logtime: Logarithmic Time Perception With Aging

Logtime: the hypothesis that our age is our basis for estimating time intervals, resulting in a perceived logarithmic shrinking of our years as we age

Ґаіджін　Gaijin｜ポイズン雷花

　Яке уявлення чи образ асоціюється у вас зі словом «ґаіджін»? 　Багато японців, можливо, вважають, що «ґаіджін» — це те ж саме, що й «іноземець». Однак, це не є точним розумінням. «Ґаіджін» та «іноземець» — не синоніми, і в реальності слово «ґаіджін» несе в собі дискримінаційний відтінок. 　Вислів

Ambiguous expressions with no tangible meanings are used generously and they keep our minds busy. Left, right, republican, democracy, socialism, capitalism, fascism, ethical, unethical, good, evil, black, white, crime, justice, success, progress, developed, undeveloped and the list goes on.

Do animals fall for optical illusions? What fish and birds can teach us about perception

Dr Maria Santacà is a behavioral biologist who specializes in the study of animal cognition and perception. Her research at the Department of Behavioral & Cognitive Biology of the University of Vienna explores how visual illusions can reveal the evolutionary roots of perception, asking whether similarities and differences across species reflect shared ancestry and neural complexity, or unique adaptations to ecological and social environments. In a newly published Frontiers in Psychology article, she uses a trick of vision where identical circles appear larger or smaller, depending on the context, to investigate differences in perception. She studied this two very different species: guppies and ring doves. In the following guest editorial, she describes how not only how fish and birds perceive their worlds, but also how ecological pressures shape the evolution of perception.
