Johannes Purkinje, noted 19th-century Czech physiologist, is said to have made
the observation that: "Deceptions of the senses are the truths of perception."

Mysteries are wonderful...And is there a greater mystery,
one closer at hand, than ourselves?
Everything that allow us to experience the fact that what we see,
hear, smell, and feel (emotionaly as well as physicaly)
are perseptions not truth; is worth investigation.
We hope you enjoy these illusions and the links to sites where you can find out the Why and How of it.

*Purkinje, Johannes Evangelista: (yhän´s ´´väng-gls´tä pr´kny) - 1787–1869, Czech physiologist. While professor (1823–50) at the Univ. of Breslau he pioneered in establishing laboratory training in German universities. From 1850 he was professor at Charles Univ., Prague, and was active in the Czech nationalist movement. He improved microscope technique and made numerous contributions in the fields of histology and embryology. He discovered the apertures of the sweat glands and the large ramified nerve cells of the cerebellum now known by his name. In his research in ophthalmology he worked on the functions of the eye, studied subjective visual figures and recurrent images, and described important phenomena concerning the eye’s sensitivity to color.

How to view the 3D Image on the right: The trick is not to focus directly on the image but try to focus on a point through the image. With a bit of patience and relaxation you will see Saturn and its rings!

The white triangle looks very real,
although there's no triangle per se.

"SATURN" |
Concentrate on the four vertical dots in the middle of the
image for 30 seconds, close your eyes, and tilt your head
back. You will see a white circle (keep eyes closed)
Keep staring at the circle... What do you see?

"Who is Bigger?" They are the same.
(Kind of like our fears maybe?)

IIt is more than "seeing the glass half full"; Things, situations, (perceptions) can be seen in various ways. Our conditioned dualistic thinking concludes it has to be "one way or the other"...or "my way." Does it really?
With this link we are not advocating the consulting services offered here (we do not know them), but this site offers some psychological insight into how we translate our perceptions into ways of thinking that color our lives. As we began with...anything that helps us to understand how we see our world is valuable.

The Necker Cube is named after the Swiss crystallographer Louis Albert Necker, who in the mid-1800's saw cubic shapes spontaneously reverse in perspective. The mind perceives the 2-dimensional shadow of a cube as a 3-dimensional object, but the 2-D image doesn't distinguish the front and back faces. You can perceive either face as being in front.

Queen Elizabeth II: Stare at the picture (on the left) for about 45 seconds.
Keep your concentration, don't take your eyes off the picture. Then, stare
at the white section on the right. You should see the Queen again.

Cube in a Corner
This picture is ambiguous in three ways:
·As a small cube in front of a larger cube;
·As a large cube with a corner cubelet cut out;
·As a small cube inside three perpendicular adjoining planes.
(is there one aspect more difficult to 'hold' ?)

As fast as you can name the color each word
is painted in; Then start over and read each
word, don't think the color ;-)
