This is one of several alternative approaches to Knowledge for Use on this Web site.
 
Competing in a technological culture requires some understanding of science and mathematics.
"Seeing" concepts is essential.  "Blindness" to concepts leads to today's prevalent pseudoscience.

Click on the space to the right to see: "The science of silt is simple but subtle," the sidebar on "Silt."  Then examine the "important perspective." Pseudoscience still rules the thinking in our culture.

Second  Glances

There's more than meets the eye(s)!
Why not see science?
Not just know...but also see.
in today's technological society it's pretty important

Even simple science is seldom what it seems at first glance.
To see, we must take some seldom sought second glances.

Go directly to a second look at Newton's laws of motion.


To get a sense of this kind of seeing consider this many-meanings metaphor:
SEEING
IS
BELIEVING
If you have "normal" human color vision you see a clear message.  If you have "protanopic" human color vision you don't.
 NOT SEEING
IS
NOT BELIEVING
Protanopic vision sees something more like this.  It's called "red-green colorblindness," but that name easily misleads us into misunderstanding.
Almost all colorblind people do see color.  But it's a different kind of color.  Different from "normal" human color, that is.

Normal

Protanopic 
The "Protanopic" picture doesn't look all that "colorblind" to someone with "normal" color vision, especially if it isn't sitting next to the "Normal" picture.  Just what is the difference between those two pictures?

Communications about color between a "normal" and a "colorblind" person is profoundly puzzling—just as is communication about science between someone who "sees" (some particular concept of) science and someone who doesn't.  What if someone else "sees" differently?  What might that mean?  How can we describe it to each other?

After all, what we see is simply what we see.  It's what we've always seen.  It's simply what's there.  We were born with our perceptions.  They are human perceptions.  They stay with us all our lives.  Unless, of course, something bad happens to us, like an accident that damages our eyesight...   or, perhaps, we get bombed by someone who is is "logic-blind" to mutual reciprocity and doesn't "see" anything wrong with  inflicting terrible things on other people if it suits his purposes.
