Molecules and molecular assemblies with more than 1000 backbone atoms have a volume fractal dimension of Dv = 2.70 ± 0.05 by the embedded sphere method and Dv = 2.71 ± 0.04 by the ensemble method using radius of gyration as the size measure. The much larger Dv = 2.89 ± 0.05 obtained ...

If any matter is smaller or larger than an atom, it is not an atom. Molecules and compounds may contain atoms, but they are not atoms themselves. Some examples of molecules and compounds are salt water (NaCl) and ethanol. Electrically charged atoms that conduct electricity are called ions, ...
Modularity means your program is built like the universe. The world is made of molecules, which are made of atoms, electrons, nucleons, quarks, and (if you believe in them) strings. Likewise, good programs erect large systems from smaller ones, which are built from even smaller building blo...

Simply put, molecules are particles composed of two or more atoms that are chemically held together; these molecules have a specific number of atomic nuclei, and can be considered an individual particle. Whether a particle consists of only one type of atom or a variety of different atoms, it...
In a 2005 interview, Moore himself admitted that "...the fact that materials are made of atoms is the fundamental limitation and it's not that far away...We're pushing up against some fairly fundamental limits so one of these days we're going to have to stop making things smaller."5...
