Classic poster by Ben Shahn

For a moment, that black and white photo should seem like a full color image. (You have to keep both the image and your head very still).

This illusion was used in the new BBC Four series Colour: The Spectrum of Science.

It demonstrates a phenomenon called “cone fatigue.” When we stare at the purple hillside in picture above, photoreceptors in our eyes called cones are stimulated. They send a signal to our brains that says “You’re looking at something purple.” But the sensing ability of those cones decreases the longer we stare at the image - those receptors are, in a way, temporarily used up.

Then when we look at the black and white image, those same cones can’t detect any purple light. Instead they sense the color that remains: green.

Behold! The best picture of Pluto you have ever seen. It was taken yesterday by the New Horizons space probe.

Here’s my video poem celebrating the New Horizons mission!

And here’s a 1 MINUTE summary of the space probe’s journey.

I forgot about this photo I scanned in a while ago. This is my great-grandfather Ancil Guy Aldrich (the boy on the far left) and from left to right Vera Woodyard(??), Mr. Woodyard, his mother Annis France Woodyard. (Ancil doesn't have the same last name because his father ran off and his mother remarried.)
