nanodreams

new knowledge today and i am once again in awe of all things scientific. i heard a presentation on nanotechnology, science and technology on the scale of a nanometer - a unit so small that one million nanometers side by side would extend the diameter of a pinhole. its estimated that a human hair is 50,000 to 80,000 nanometers wide and grows at the approximate rate of 10 nanometers per second. the scale alone confounds me. couple that with the technology thats being developed on that scale: nanotubes lighter than a feather and a thousand times stronger than steel in sports equipment, silver nanoparticles thought to repel bacteria and viruses, nanovelcro that may some day replace welding and nails. odd that i have such big thoughts for so tiny an entity.
