* Molecular orbital

Molecular orbital theory was seen as a competitor to valence bond theory in the 1930s, before it was realized that the two methods are closely related and that when extended they become equivalent.

Molecular orbital ( MO ) theory uses a linear combination of atomic orbitals ( LCAO ) to represent molecular orbitals involving the whole molecule.

The theory has been presented in 2005 by Marc W. Kirschner, a professor and chair of Department of Systems Biology at Harvard Medical School, and John C. Gerhart, a professor in Molecular and Cell Biology, University of California, Berkeley.

* Kinetic theory, also referred to as Kinetic Molecular Theory

Molecular orbitals arise from allowed interactions between atomic orbitals, which are allowed if the symmetries ( determined from group theory ) of the atomic orbitals are compatible with each other.

In 1963 Parr published Quantum Theory of Molecular Electronic Structure, one of the first books to apply quantum theory to chemical systems.

During the next decade, confocal fluorescence microscopy was developed into a fully mature technology, in particular by groups working at the University of Amsterdam and the European Molecular Biology Laboratory ( EMBL ) in Heidelberg and their industry partners.

In 2000, a special section of the Proceedings of the National Academy of Sciences ( PNAS ) was devoted to " evo-devo ", and an entire 2005 issue of the Journal of Experimental Zoology Part B: Molecular and Developmental Evolution was devoted to the key evo-devo topics of evolutionary innovation and morphological novelty.

Despite being told that it was against the rules, Ender sacrifices most of his fighters fleet to launch a Molecular Disruption Device at the planet, destroying the planet and the entire Formic fleet.
