Scientific Art or Artistic Science?

Artists represent natural phenomena whereas scientists interpret them.

Pictures are devoid of two dimensions present in objects – depth and
motion. The depth is allusory and the motion is implied.

I will argue that artists have
influenced science in the
context of space.
On the other hand, scientists
have affected the ways in
which motion is represented.

In the 1920s, Gestalt psychologists described the ways in which
elements of patterns are grouped together perceptually.

Mosaic of Ocean (from the 2nd century). Roman mosaics manipulated
the elements of pictures (tesserae) to produce complex Gestalten. The
artists demonstrated their knowledge of pictorial principles rather than
the interpretations of them.

Gestalt psychologists were also intrigued by perceptual ambiguities,
like the Necker cube and Rubin’s vase/faces figure, literal variants of
which are shown here.

Ambiguities of profiles and vases (like that by Crussaire in 1799) were
exploited in art long before they were examined in visual science.

An Italian artist called Giuseppe from around 1700 showed that
species and gender barriers could be crossed with inverted figures!

Rex Whistler (1905-1944) used the technique extensively.

mirrors and prisms.

of three dimensions to two, and few more so that Salvador Dali

“Ceci n’est pas
Magritte”
René Magritte
revelled in the
ambiguity of the
picture plane and
also that between
word and image.

“The integrity of words”
![Page 32: Nicholas Wade, University of Dundee - SMFL · 2014. 8. 29. · Nicholas Wade, University of Dundee. Artists represent natural phenomena whereas scientists interpretthem. “Visual](https://reader035.vdocuments.mx/reader035/viewer/2022071509/6129a6033d5c2132542f287c/html5/thumbnails/32.jpg)
The rules of image formation on a picture were determined two
centuries before the same principles were applied to the eye.
Filippo Brunelleschi (left) produced pictures in perspective before
1420, whereas Johannes Kepler (right) described the formation of
an image on the retina in 1604.
![Page 33: Nicholas Wade, University of Dundee - SMFL · 2014. 8. 29. · Nicholas Wade, University of Dundee. Artists represent natural phenomena whereas scientists interpretthem. “Visual](https://reader035.vdocuments.mx/reader035/viewer/2022071509/6129a6033d5c2132542f287c/html5/thumbnails/33.jpg)
No sooner had the rules of perspective been formulated than
they were distorted. Leonardo da Vinci produced examples of
distorted perspectives or anamorphoses.
![Page 34: Nicholas Wade, University of Dundee - SMFL · 2014. 8. 29. · Nicholas Wade, University of Dundee. Artists represent natural phenomena whereas scientists interpretthem. “Visual](https://reader035.vdocuments.mx/reader035/viewer/2022071509/6129a6033d5c2132542f287c/html5/thumbnails/34.jpg)
Jean-François Niceron (1613-1646) described the construction and
mathematics of these curious perspectives. He produced linear,
conical, and cylindrical (mirror) anamorphoses.
![Page 35: Nicholas Wade, University of Dundee - SMFL · 2014. 8. 29. · Nicholas Wade, University of Dundee. Artists represent natural phenomena whereas scientists interpretthem. “Visual](https://reader035.vdocuments.mx/reader035/viewer/2022071509/6129a6033d5c2132542f287c/html5/thumbnails/35.jpg)
The optical principles on which
anamorphoses are based are
precisely those used by
Adelbert Ames (1880-1955) in
his perceptual demonstrations.

Cubists, like Pablo Picasso, were producing essentially 2 ½ D
sketches related to those depicted by visual scientist David Marr.

Brunelleschi’s vision was monocular, whereas that of Leonardo was
binocular. His deliberations over ‘natural perspective’ led him to
examine the depth seen with two eyes.

Scientific influences of art have derived mostly from the other
lost dimension of pictures – motion. Rather than implying
motion scientists synthesised it.

Marcel Duchamp utilised visual persistence, and he also made
rotoreliefs that induce kinetic depth effects in the 1930s. They were
studied in visual science by Musatti (1929)

They have played
a major part in Op
Art – the genre
that closely binds

Thomas Young described his own regular astigmatism in 1801, and
transient astigmatism has been amplified extensively in the art of
Bridget Riley and other Op artists.
