Brings to mind first-year physics labs. My 3 lab partners were all male.
One day we went in and the lab instructor says - "Guys you'll be doing
this one today". It was an experiment on finding harmonics. She told me
women can't ususally hear the spot as easily as men. It was true. My
partners had no problem hearing the harmonic point as we filled the glass
tube with water. I heard a vague buzzing. The tables were turned when
we did optics. Find a second or third order green in a split spectrum.
I can discern, under the right conditions, up to seven orders. My
partners only saw one shade of green.

What's "green"?

RCE


Leaves, grass, seaweed, Kermit

It's not that easy . . .

Reminds me of something I learned while working in the optical coating
industry. It seems that nature's version of "green" is one of the most
difficult colors to artificially recreate. The military has dealt with this
issue for many years, trying to develop green camouflage colors without
success. The human eye and optical instruments can pick out the fake from
the real with no difficulty.

Yet, in nature, there are many animals that can quickly take on the color of
surrounding leaves or brush and effectively disappear. The same optical
instruments have a hard time resolving them.
