Computer made from liquid crystals would ripple with calculations

A proposal for a computer built using liquid crystals – similar to those found in LCD TVs – would use the orientation of the molecules to store data. Calculations would look like ripples through the liquid

SALISBURY, ENGLAND - Challenger 2 Main Battle Tank during a training exercise on Salisbury Plain Training Area in Salisbury, England. 5 RIFLES Battlegroup prepares for deployment on Op CABRIT in Estonia as part of the NATO enhanced Forward Presence later this year. 5 RIFLES Battlegroup is trialing a new concept of training or Operational Readiness Model (ORM) on behalf of The Field Army to ensure they are mission ready. Additionally, due to the Coronavirus pandemic, training methods have been adjusted with innovative measures introduced to ensure that training isn't compromised and expectations and operational outputs lowered.
