The name on the tip of the tongue highlights cryptography and numbers as basic aspects  of contemporary life that remain under the surface of its design. It is inspired by two numeric  decomposition problems: RSA, one of the first Public-Key cryptographic system, which is based  on the challenge to decompose a very large number in two prime factors; and Goldbach’s conjecture,  which proposed that any even number greater than two can be written as the sum of two prime numbers.  Through calculation and drawing, The name on the tip of the tongue is a spatial investigation into structures  of organization. It makes reference to the first list of prime numbers and factors up to the number 144,000,  written by Anton Felkel in 1776.
