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

This image may not be used in educational posters Double-slit experiment Computer illustration showing a plane wave (bottom right) passing through a gap in a screen, and the resultant circular wave then passing through a screen with two gaps. The gaps act as new wave sources and the wavefronts bend to create two sets of circular waves radiating outwards. These two new waves create an interference pattern as they interact. At the point where a wave peak from one hits a wave peak from another, or a trough hits a trough, they reinforce each other; their magnitudes are summed. This is known as constructive interference. Where a trough hits a peak or vice versa and they cancel each other out. This is known as destructive interference.
