 nano technology |

Anybody who doesn't know much about nanotechnology should begin with geckos. These are the lizards that are probably the world's best climbers. Watching them climb upside down on a horizontal pane of glass, you realize that spiderman should really have been called geckoman. These guys outclimb spiders any day.
With perfect ease they can hang from a single toe, and they do so by pure adhesion, not by sticking a toe in a hole or by curling it round something they can grip. With all the toes on the glass scientists estimate that if the rest of the body were strong enough it could take the weight of a 100kg person suspended below it. Although each toe is equipped with a tiny hook-like claw at the end, these are of no use on the glass. What keeps them up there is the amazing structure of the skin of the toe.

The first use of the concepts in 'nano-technology' (but predating use of that name) was in "There's Plenty of Room at the Bottom," a talk given by physicist Richard Feynman at an American Physical Society meeting at Caltech on December 29, 1959.

Companies that make amateur gear use surface mount devices (SMD), real small ICs because they got $100,000.00 manufacturing gear like wave soldering machines to work with that stuff. I have hand soldered a few SMDs. I have read a few articles of those who have techniques for it, but those don't include the SMDs that have pads on the bottoms which is the domain of wave soldering. I prefer to stick to DIP configurations.

Nanotechnology is significant on account of of its pre- eminence upon the comprehension, use, and control of matter at magnitudes of a minute scale, akin to approaching atomic levels, with which to manufacture new substances, instruments, and frameworks.

A basic definition: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more ..

If you have ever thought of having an acupuncture treatment but haven't for fear of needles, there is no need to fear now. In a new form of treatment silicone chips are placed on the skin instead of piercing it with acupuncture needles.

Richard Feynman delivered a lecture at the American Physical Meeting Society about how molecules and atoms could be manipulated using specially-designed instruments.
