Signals is a collection of algebraic poems written in Lincos, the mathematical language designed for communicating with extra-terrestrial intelligences. Each poem is accompanied by exoplanet search imagery derived from Kepler telescope data.

Lincos itself was formulated by Hans Freudenthal in 1960, and is less a fully formed language, than a set of principles for using mathematics to communicate information concerning both scientific understandings of the observable world, and also for expressing insights into human behaviour and life on Earth more broadly. Freudenthal chose these foundations on the premise that a grasp of numerical relations were the only likely point of shared understanding between human and extra-terrestrial intelligences.

Each poem in the collection is depicted using an adaptation of a noise-resistant graphical alphabet designed in 1999 by astrophysicists Yvan Dutil and St├ęphane Dumas, which they used for their own Lincos radio message to the cosmos.

In March 2022, Signals was published by Guillemot Press. It can be purchased here.

As an accompaniment to Signals, an audiovisual rendition of the text, modelled to evoke a frequency key shifted radio transmission, is available on YouTube.
