Samurai swords were made in an elaborate, repetitive process that was ritualized to ensure the integrity of the methodology. A piece of iron was heated in a forge and folded and flattened many times to create layers of iron and carbon and iron oxide that were formed into swords with strength, flexibility and able to […]

Smart Sand Replicator

Until we invent a replicator that works by using an energy beam to transport molecular material, we have to make copies the old fashioned way – using solid materials. MIT is working on the mathematics required to make copies of objects using a smart sandbox. Self-sculpting sand – [mit.edu] New algorithms could enable heaps of […]
