Document Summary

Global information society: human societies are becoming into. Mass communication: traced back to the invention of printing press. Apply pressure on an inked surface at the top of print medium: cloth paper. Broke / cracked enigma code during world war. Science of materials at the molecular or subatomic level. Slicing or cutting larger particles to nanosized structures. Titanium dioxide -> glass surface reject dirt -> self cleaning. Carbon nanotubes + paints / plastics = strength and conductivity. Superior materials; removal of radioactive cesium and iodine ions in water. Woven from tiny wires of potaasium manganese oxide. Cost significantly less than treatment methods that require the water to be pumped out of the ground. Generate light when that particular genetic target is found. Encapsulate / help deliver medication to cancer cells. Minimize the risk of damage to healthy tissue. Gold nanoparticles detection of targeted sequences of nucleic acids. + fluorescent protein = system for diagnosis of cancer.
