[Yasmin_discussions] Fwd: Light is My Business


while we are on speculating about
light= my colleague max schich referred us to this
Dawkins TED talk

There's nothing inherent about red that makes it long wavelength.

Must see on this topic:

" I've even suggested, use perceived hues, such as red and blue, as
labels, internal labels, for some useful aspect of echoes -- perhaps
the acoustic texture of surfaces, furry or smooth and so on, in the
same way as swallows or, indeed, we, use those perceived hues --
redness and blueness etc. -- to label long and short wavelengths of
light. There's nothing inherent about red that makes it long

which also brings me to Eric Kandel's excellent book "The Age of Insight:

The Age of Insight: The Quest to Understand the Unconscious in Art,
Mind, and Brain, from Vienna 1900 to the Present

I highly recommend this book to anyone in the art-science community= there are
excellent chapters on visual perception and how the Viennese artists
in the 1880s
Kokoshka etc exploited some of the amazing complexities of how visual perception
translates into visual interpretation of scenes- much discussion of the gestalt
and how we understand this neurobiologically now- and the complexity
of 'non verbal'
communication between humans

how light received in the eye becomes awareness and sophisticated hypothesis
testing in the visual cortex , before settling on 'seeing" is an amazing process
