The UNSEEN series by Ramon Suau is a thought-provoking exploration of the impact of information and decision-making, how to cope with uncertainty and randomness in environments of extreme complexity. Drawing from research on flat geometric structures such as the Ulam spiral and the Sacks spiral, which reflect the actual distribution of prime numbers within the line of natural numbers and the concept of the Gaussian pit, Suau delves into the interaction between the relevant and the superfluous, the apparent and the unnoticed, and the complex mathematical structures that underlie all of them.
