Wherein it is related how that polygon of womanly virtue, young
Polly Nomial (our heroine) is accosted by that notorious villain
Curly Pi, and factored (oh, horrors!).
Once upon a time (1/t) pretty Polly Nomial was strolling across a
field of vectors when she came to the boundary of a singularly large
matrix. Now Polly was convergent and her mother had made it an
absolute condition that she never enter such an array without her
brackets on. Polly, however, who had changed her variables that
morning and was feeling particularly badly behaved, ignored this
condition on the basis that it was insufficient, and made her way
amongst the complex elements. Rows and columns closed in from all
sides. Tangents approached her surface. She became tensor and tensor.
Quite suddenly, two branches of a hyperbola touched her at a single
point. She oscillated violently, lost all sense of directrix, and
went completely divergent. As she reached a turning point, she
tripped over a square root that was protruding from the erf and
plunged headlong down a steep gradient. When she rounded off once
more, she found herself inverted, apparently alone, in a non-euclidean
space.
