Inflation. Expansion. Strong nuclear interaction. Particle-antiparticle annihilation. Nanotechnology summary Just give me the FAQ The next few paragraphs provide a brief introduction to the core concepts of nanotechnology, followed by links to further reading. Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water and air we can make potatoes. Todays manufacturing methods are very crude at the molecular level. It's like trying to make things out of LEGO blocks with boxing gloves on your hands. In the future, nanotechnology (more specifically, molecular nanotechnology or MNT) will let us take off the boxing gloves. "Nanotechnology" has become something of a buzzword and is applied to many products and technologies that are often largely unrelated to molecular nanotechnology. Nanotechnology will let us: Some Frequently Asked Questions More Information Books
