A Troika of Quantum Sciku by Jeffery Shevlen

Pauli Exclusion Principle

No suborbitals
Take electron pairs whose spins
consent to agree

Aufbau Principle

Electrons always fill
The lowest energy
Sub-orbitals first

Hund’s Rule

Before forming pairs
Electrons first fill each sub-
Orbital alone

These poems are broadly about the properties of atoms. More specifically they describe three simple rules that came from of the flowering of quantum discovery roughly 100 years ago. Each describes how electrons can populate the zones around an atom’s nucleus which are called orbitals. To me haikus, scikus, wonderfully compliment the subtle interactions of the subatomic realm. Egoless nature, all the way down.

Wikipedia devotes three pages to each of the three axioms. For a more detailed explanation wikipedia is a fine place to start:

Progress by Dr Katy Roscoe

In mid-2021 The Sciku Project teamed up with the Literature and Science Hub at the University of Liverpool to run the ‘Research in Verse Poetry Competition’, open to staff and postgraduate research students across the university to submit poems about their research subject. The competition saw poems addressing all sorts of topics, ranging from gravity to slavery to life in the lab.

Second prize was won by Dr Katy Roscoe for her poem ‘Progress’:

Progress

The scratching and scraping of steel on rock,
In concert our muscles, they crunch and creak.
Slow inch by inch we chisel out the dock,
Ankles bound in irons, the hulls in teak.

Wiping sweat from my brow, I gaze afore:
I’m dazzled – bright sun, blue sky, white lime.
Ocean’s eternity returns ashore,
An excess of brightness ¬– like hope – can blind.

Night falls, men drive us into beached ships,
Dank air, sodden bodies, yellow fever.
Vessels for human cargo turned crypts,
If my body holds out, I will leave here.

Will I be able to retrieve the past,
Or will that monolith be all that lasts?

Background

My research is about convicts who quarried stone to build the naval dockyard at Bermuda, an Atlantic archipelago. Around 9,000 British and Irish men, many poor and starving, were transported there from 1842-63. Prisoners slept in decommissioned ships (hulks) which were dirty and crowded. Over 1200 men died there from effects of hard labour and yellow fever. Some went temporarily blind (opthamalia) from sunlight reflecting off limestone. “Retrieve the past” is a quote from a convict’s letter (1857). He hoped to be released under a “Ticket-of-Leave” in Australia, where he could earn an honest living, rather than return home.

Dr Katherine (Katy) Roscoe is a historical criminologist at the University of Liverpool with research interests centred on global mobilities, unfree labour and racial inequalities, with a particular focus on mid-nineteenth century crime and punishment in Britain and its former empire.

Entropy by Robert Erlandson

The second law of thermodynamics is a fundamental law of nature. One expression of this law states that the level of disorder in the universe is steadily increasing. Entropy is a measure of the system’s disorder, higher entropy means more disorder.

The image above is known as a ‘haiga’ – a coupling of poetry and imagery, the idea being to create a third art form that is greater than the sum of its parts. Below is an alternate version of the poem that takes the same starting point to create a tanka.

Renegade liquid

Renegade liquid –

negative mass pushing back

breaking second law.

 

One of the fundamental aspects of Newton’s second law states is that when an object has a force applied to it, it moves in the same direction as the net force. Khamehchi et al (2017) created a liquid of negative effective mass (a Bose-Einstein condensate) that breaks this principle: when it is pushed it accelerates towards the pusher.
