"...over the years as mathematics became more and more complicated,
people concentrated more and more on the numbers, the formulas, the
equations, and the methods, and lost sight of what those numbers, formulas
and equations were really about and why those methods were developed.
They lost sight of the fact that mathematics is not about manipulating
symbols according to arcane rules but is about understanding patterns-patterns
of nature, patterns of life, patterns of beauty."
