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. Interactive space simulator. We come from the future. This is, for the most part, an accurate article, except for a few statements.
"Exactly what makes a fermion a fermion is a bit complicated, but suffice it to say that fermions are all the particles that deal with matter. So what about the last group of elementary particles, the ones that don't deal with matter? These are the bosons, and they deal with the fundamental forces of the universe. " The statements above can be misinterpreted as suggesting that fermions are defined as particles that deal with matter and bosons are defined as particles that deal with forces.
And that is not true. Particles that deal with matter are fermions and particles that carry the fundamental forces are bosons. What fermions and bosons really are have to do with two apparently unrelated (but actually related) particle properties: spin and statistics. "There are four known bosons" See, this is an example of the misconception I just mentioned. According to special relativity, not general relativity. How Things Work - How Things Work Home Page.
