Among the many striking artifacts discovered at Pompeii is the famous SATOR square, a five word palindrome that can be read from top to bottom, bottom to top, left to right and right to left:

The Fibonacci sequence crops up in many different contexts in both nature and mathematics. Starting with 0 and 1, each number in the sequence is the sum of the two preceding numbers, giving

0,   1,   1,   2,   3,   5,   8,   13,   21,   34, …

and so on. The sequence is named after the Italian mathematician Leonardo Pisano, whose nickname was Fibonacci. 

Tributes have been paid around the world to Eavan Boland, the Irish poet, feminist and academic who died on the 27^thApril. Her writing is distinguished by clarity and depth, by the precision of her language and her ability to pull together details of simple, everyday experiences, opening our awareness to their profound underlying truth.

The margins of decision-making can be fine. This morning I awoke with a mild sore throat and a headache. In normal circumstances I would not give any thought to these very minor symptoms: but these are not normal times and, being a dutiful citizen, I contemplate the need to self-isolate. 

When my husband and I first moved to Aberdeen in 1983, we stayed briefly in a house on Clerk Maxwell Crescent.  It shames me now to admit that at the time I had only the vaguest idea who James Clerk Maxwell was, despite having studied electromagnetism as part of my undergraduate degree.

…the forces
that divergent guide my life
are like two teams of horses
straining at my heart.
Yet I contain no vacuum –
and am slowly torn apart.

This snippet of a poem, written when I was seventeen, expresses the conflict I felt between my passion for the arts and for the sciences, specifically between poetry and applied mathematics. To my teenage self, the two seemed inherently incompatible. Mathematics, as I understood it at the time, was logical and disciplined, whereas poetry required what Keats described as ‘Negative Capability, that is when a man is capable of being in uncertainties, Mysteries, doubts, without any irritable reaching after fact & reason’ (Keats, 1817).

Was it like that for you as well, when you were at school? Words lived. They had histories, back-trails to ancient Greek rhetoric or Roman sensibility, to mediaeval French farms, soggy lowland water-meadows, absurd colonial rituals. They sang, they danced, with their own characteristic rhythm and energy. You could play with words, write stories, compose poems, tell jokes, formulate riddles, act them out, set them to music. And you could read them, voraciously.
