Sunday Science Poem: Abstraction is crucial in science and poetry

Newton-WilliamBlakeI recently heard a presentation by the Caltech biophysicist Rob Phillips, in which he issued a challenge to those who claim biology, in contrast to physics, is too complex and messy to be understood with mathematical theories: take a look at Tycho Brahe’s 16th century astronomical data, and see if you can make sense of it without math. Take a look at the data, and see if you can demonstrate, without a mathematical theory, that the orbit of Mars is an ellipse.*

In order to understand the messy real world, scientists use abstractions that can be quite distant from our everyday experiences. The historians of science Stephen Toulmin and June Goodfield explain how this was crucial to Newton’s method:

[W]here Aristotle’s theory of motion was based on familiar, everyday principles, Newton’s was stated in terms of abstract mathematical ideals. The circling heavens, a falling stone, smoke rising from a fire, the steady progress of a horse and cart: these were the objects by comparison with which Aristotle explained other kinds of motions. For Newton, on the other hand, the explanatory paradigm was a kind of motion we never encounter in real life. Nothing ever actually moves uniformly and free of all forces, at a steady speed and in a constant Euclidian direction. Yet Newton was able to bring together the threads left loose by his predecessors by systematically applying just this abstract idea of ‘natural’ motion. So far from being guided by experience alone, he could not afford to be too much tied down to the evidence of his senses, or to the results of experiments: it was, rather Aristotle who stuck too closely to the facts. Newton was ready to imagine something which was practically impossible and treat that as his theoretical ideal.

Musicians, artists, and poets have also found that abstraction is crucial. The abstract features make it tough for most of us to grasp modern works. Jacques Barzun explained it this way:

Like the would-be purist in art, the scientist takes a concrete experience and by an act of abstraction brings out a principle that may have no resemblance to the visible world… Poets and prosaists, whether Abolitionist, Decadent, or Symbolist, found that to create works adequate to their vision the language must be recreated.

If we recognize the common role of abstraction in art and in science, the baffling poetry of someone like Arthur Rimbaud begins to make much more sense.

Rimbaud’s poetry can seem like a words thrown together carelessly for shock effect, but this casual impression is wrong. Daniel Mendelsohn writes that “as much as we now like to romanticize Rimbaud as a Dionysian rebel, spontaneously tossing off revolutionary verses, the fact is that he made himself a poet by following a distinctly Apollonian trajectory—‘a long, involved, and sober study of the history of poetry.’” With his careful preparation, Rimbaud could carry poetry in a new direction: “[Rimbaud] suddenly saw that the true subject of a new poetry couldn’t be the usual things—landscapes, flowers, pretty girls, sunsets—but, rather, the way those things are refracted through one’s own unique mind.”

We’ve discussed abstraction, science, and poetry, and all three come together in Rimbaud’s poem Mouvement, in which technology, industrialization, and their impact on our human journey through the rough seas of nature, are refracted through Rimbaud’s “own unique mind.”

Movement

The movement of lace at the brink of the weir,
The gulf at the stern,
The swiftness of slope,
The vast sway of the current
Draw the voyager through extraordinary lights
And chemical change
Surrounded by waters of the vale
And the strom.
 
These are the conquerors of the world
Seeking their personal chemical fortunes;
Amusement and comfort travel with them;
They carry the education
Of races, classes and creatures, on this vessel
Repose and vertigo
In the diluvial light,
In terrible nights of study.
 
For from the conversation among the equipment, the blood, the flowers, the fire, the gems,
The anxious calculations on the fleeing deck,
– One sees, rolling by like a dyke beyond the hydraulically-powered road,
Monstrous, illuminating endlessly – their store of studies;
Driven themselves into harmonious ecstasy,
And the heroism of discovery.

Among the most surprising atmospheric events,
A young couple hold aloof on the ark,
– Is it a pardonable primitive shyness? –
And sing and mount guard.

* Phillips goes even further: he challenges anyone to take the black box computation, ‘big data’ approach so common in biology, and deduce the shape of planetary orbits from Brahe’s data.
