Interaction of Color


We are the embodied.

As humans we can nothing other. If we are then are deficient in some way. And as such we have the ability to see three colours. We have red, blue and green receptors in our eyes to interpret light which is abundant in the space around us (compare our eyes to the Mantis Shrimp).

At the same time our eyes have limits we do not notice. They are enough for what we need. Nonetheless they have deficiencies which do not hinder us much but let us get along fine in daily life.

Josef Albers’ Interaction of Color highlights the way our eyes perceives colours. The flaws are shown (as only we know how to do so well) to point out just how much we rely on them, how little we notice our visual and other perceptual systems.

This reprinted 50th Anniversary Edition is a must-read for all interested in cognition.

What do teachers make?

20130806-072237.jpgIf you ever have doubts about your self worth as a teacher then you should read this. Whoever said “those who can do; those who can’t teach” wasn’t a teacher. He (and I will use the masculine here) would probably have made a lousy teacher anyway. And here his jealousy had turned into spite. How unfortunate.
