A first step toward understanding science: the mysterious undeniable
Once you've seen it, you can never again not see it.

 Two-tone paint job? A five-cut solution? Up or down? 31 dominos? Who gets injured?

You can find magic in places you never before thought to look.
The magic you might find in Portland leads you to many hidden clues to understanding science: LOOK!

Seeing science is seeing a lot of kinds of errors you never realized were possible.

How might a person who sees something know when someone else does not?

 A  man named Joe was painting his house with green paint, but he ran out of paint half way through the job.  So Joe painted a swatch on a stick with the wet brush and took the stick to the paint store.  He compared his stick to the cans of paint until he found one that matched, and bought it.   He finished the house painting with the new can of paint. His neighbor, Mary, looked at the new paint job and knew that something was wrong.  She asked the proud painter,  "How come the two-tone paint job?" "What d'ya mean, 'two-tone paint job'?"
 The painter had "protanopic" colorblindness (but didn't know it).  Neighbor Mary had normal human color vision.   Protanopic color vision doesn't seen any difference between grass green and orange because the protanopic eye has only two of the three color distinguishing cones of the "normal" eye.  The red-sensitive cones are missing. The color cube diagram below shows how the two kinds of color vision see the colors.  The colorblind person can come to understand the difference between the different ways he and his neighbor see color, but only if he delves into the depths of abstraction of the mathematics and science of color vision.  His neighbor simply sees the difference. ...and it's undeniable... A larger look at COLORBLINDNESS

 Normal human color vision sees this. Three dimensions are needed. and protanopic vision sees this. The third dimension isn't needed. It's two dimensional.

Someone also might know when someone else doesn't understand something that is more abstract.
 Martin Gardner's buzz saw A carpenter, working with a buzz saw, wishes to cut a wooden cube, three inches on a side, into 27 one-inch cubes.  He can do this job easily by making six cuts through the cube, keeping the pieces together in the cube shape.  Can he reduce the number of necessary cuts by rearranging the pieces after each cut?  Either show how or prove that it's impossible. from Martin Gardner's "Mathematical Games," in Scientific American
 The solution to this puzzle is very simple, but it requires that we look at the problem in a certain way.  Until we look in that way, we don't "see."  Try to solve it first, and then follow up by going to Da Vinci Days, 2002. A person who has looked and seen can easily tell when someone else hasn't seen.   While, "Everyone's entitled to their opinion," some opinions surround a person with an aura of ignorance that is obvious to the person who has seen.  The insight needed to solve Martin Gardner's puzzle isn't very deep, and most people will be able to improve their aura through their discovery of the solution: "Eureka!  I've seen it!"

 Mathematics
The level of abstraction might be deeper yet.
Someone who understands elementary physics might be able to spot when someone else doesn't.

 Logic Relationships
And deeper...
Those with a strong sense of elementary logic often spot when someone else makes a logical error.
