"Rays I and II arrive in such a
way as to form a particular angle
to the horizontal, in the manner
shown. In order for these rays to
intersect at point A, you need to
install two reflectors. At what
angle to the horizontal do these
reflectors need to be, in order for
the rays to intersect at point A?"
Every day, Pieris butterflies
solve a problem like this, of the
kind you might expect to find in
university exams. They accurately calculate these angles to make the maximum
use of the Sun's light. These butterflies have never been taught by any physics
teacher, but are able to perform this calculation thanks to the inspiration of God,
the Omniscient.

MAGNIFICENT OPTICAL DESIGN IN THE FOUR-EYED FISH
When swimming underwater, everything around you appears
blurred. That's because water represents a very different environment
for our eyes, which have been created to be able see in an atmospheric
environment. Accordingly, a fish taken out of its normal habitat into
an atmospheric environment might also be expected to see every-
thing as blurred. However, one species of fish, which lives in rivers
and lakes from Southern Mexico to northern South America, can see
very well both in the water and above. This is the anableps, better

known as the four-eyed fish. Not only able to see very clearly outside
the water, this fish can even focus on objects in the air.
The anableps actually has only two eyes, but each is divided hori-
zontally; that is, each eye has two separate optical systems, each with
its own focal length. This flawless design explains why the anableps
see two different images at the same time. When swimming slightly
