“In fact the smallest units of matter are not physical objects
in the ordinary sense; they
are forms, ideas which can be expressed unambiguously only in mathematical language.” –Plato (the apparent father of quantum theory!) |
There are an estimated 1.618 million web sites dedicated to
recreational mathematics. Many of them feature interesting and useful
material, but there is mammoth duplication of content. I strongly desire
not to contribute to the clutter, hoping to offer perspectives
sufficiently unique that they will not be encountered elsewhere.
Doubtless these materials will interest only a small percentage of
visitors. No advanced learning is required here, though;
a reasonable awareness of high-school math is sufficient.
