Love and Tensor Algebra

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 a2 cos 2 phi!

Love and Tensor Algebra is from the book The Cyberiadwritten by  Stanislaw Lem. Stanis?aw Lem was a Polish writer of science fiction, philosophy and satire. The Cyberiad is one of his best work.

The Cyberiad (Polish: Cyberiada) is a series of short stories. The Polish version was first published in 1965, with an English translation appearing in 1974. The main protagonists of the series are Trurl and Klapaucius, the “constructors”. The vast majority of characters are either robots, or intelligent machines. The stories focus on problems of the individual and society, as well as on the vain search for human happiness through technological means. The poem Love and Tensor Algebra found its way to this blog because of its mathematical flavor. And I love reciting it.

Mathematics is an art

Whether we are conscious of it or not, the way we teach mathematics is very much influenced by what we conceive mathematics is and what is important knowing about it. As part of our Lesson Study project with a group mathematics teachers, I was tasked to share my thoughts about the nature of mathematics and its implications to its teaching and assessment.

What is mathematics?

I have always believed that mathematics should be experienced by the k-12 learners as both practical and theoretical, as a language, as a process of thinking and, as an art.  Of these five, I have always felt the least confidence in speaking of mathematics as an art. Most of the times, my “mathematics is an art” becomes “there is art in mathematics”. The latter is much easier to discuss because teachers know this so there’s not much need for me to explain. What I do and I don’t know if I get away with it, is give beautiful examples. Here are two of them. Click image to get to the source.

Math Art | Love and Tensor Algebra via kwout

Where there is art, there is beauty. And what is the beauty of mathematics? In most cases, it’s in patterns. I would regale teachers with patterns in nature that mathematics could perfectly represent and capped my lecture with Galileo’s pronouncement that Mathematics is the language used by God to write the universe. With this, I could get away from mathematics as art to mathematics as language.

Then I came across this post titled What is an art? which defined art as a habit of thinking, doing, or making that demonstrate systematic discipline based on principles. The post described arts as about connections and that understanding the connections between things allows designers to accomplish their goals. It described  art as based on principles and not just a series or procedures or methods; that there can be many methods inside an art …  Finally, and I love this part, it said that art must be acquired as a habit, so that its practitioners become “unconsciously competent.”  I thought the post could very well be speaking of teaching and learning of mathematics especially in its giving  importance to making connection, open-ended problem solving, and the acquisition habits of mind which are favorite topics of mine when I’m invited to share my thoughts about mathematics teaching.
