Connecting science with perception

I have two ongoing series of posts, one on perception and the other on how science works.  These are very much connected, as I will explain in this post.

My interest in the main topics of this blog led me to study the question of how humans learn.  I understood, all along, that the increase in scientific knowledge is closely related to learning.  Or, as I think Quine puts it, science is learning writ large.  Thus I used the growth of scientific knowledge as a publicly observable instance of learning.
