Symmetries
SYMMETRIES allows the
visitor to experiment with a variety of symmetrical patterns. They
can select from 15 symmetries and draw and erase their own designs
on the video screen. Symmetry means something can be turned, slided,
or flipped, and it still looks the same. There are a lot of different
symmetrical objects that occur in nature. A leaf is an example of
mirror symmetry—both halves are identical, as if one half was
a mirror image of the other. A daffodil represents rotational symmetry.
It can be turned a certain amount and it still looks the same. A
row of corn kernels is like translational symmetry. Sliding down
the row, the pattern is the same.
