Growing crystals to generate random numbers

Phys.org  February 19, 2020 The process of crystallization is random due to many factors that come into play as chemicals in a liquid solution evolve from a disordered state to one that is very organized. Researchers in the UK created a crystallization array and attached a reagent dispenser put different chemicals into the cups. A camera took a picture of each of the cups as crystal formation began. Each of the pictures was converted to a zero or a one based on nothing but the geography of the crystal. The zeros and ones were then strung together to form a […]
