Love and Tensor Algebra - from "The Cyberiad" by Stanislaw Lem

*"Come, let us hasten to a higher plane*

Where dyads tread the fairy fields of Venn,

Their indices bedecked from one to n

Commingled in an endless Markov chain!

*
Come, every frustrum longs to be a cone*

And every vector dreams of matrices.

Hark to the gentle gradient of the breeze:

It whispers of a more ergodic zone.

*In Riemann, Hilbert or in Banach space*

Let superscripts and subscripts go their ways.

Our asymptotes no longer out of phase,

We shall encounter, counting, face to face.

*I'll grant thee random access to my heart,*

Thou'lt tell me all the constants of thy love;

And so we two shall all love's lemmas prove,

And in our bound partition never part.

*For what did Cauchy know, or Christoffel,*

Or Fourier, or any Bools or Euler,

Wielding their compasses, their pens and rulers,

Of thy supernal sinusoidal spell?

*Cancel me not - for what then shall remain?*

Abscissas some mantissas, modules, modes,

A root or two, a torus and a node:

The inverse of my verse, a null domain.

*Ellipse of bliss, converge, O lips divine!*

the product o four scalars is defines!

Cyberiad draws nigh, and the skew mind

Cuts capers like a happy haversine.

*I see the eigenvalue in thine eye,*

I hear the tender tensor in thy sigh.

Bernoulli would have been content to die,

Had he but known such a^2 cos 2 phi!"
