Navigating Second Glances

The boats are links to discovery

Floating down a river on a lazy afternoon...  As infants, we had learned to perceive.  As children, we had learned how to move effectively and go where we want.  As adults, we learned how to navigate—even, perhaps, down an unfamiliar river...

"Drifting here, you learned to perceive, not to preconceive, what makes a land beautiful..."
David Brower

Knowledge for Use.
A treasure hunt.
Watch for hidden surprises and occult meanings.  The treasure is a web of hidden passageways into man's newly discovered realms in "rationality-space."  It can extend your knowledge into vast realms of usefulness that have been:

Perception is a strange thing.  What we see seems like just what's there.  Nothing more.  Nothing less. 1SEE scienceNot so!

Mother Nature worked millions of years on our perceptions.  We are born blind and gradually become able to "see" just a little of our world. 2There's more than meets the eye.Mysteries

Dimensionality is like the dots on your computer screen.  This insight digs deeper into dimensionality than does the spatial thing we know so well.

When very young, we learned how to move effectively and go where we want.  Mankind travelled a long way in time before discovering the rules of the road in space. 4Look at the dawn of modern science.The Rules
