In science, human molecular science, or 'hmol science' in short, truncated to "hmolscience" (c.2013), is the study of humans from the external atomic perspective.

Overview
The essential component of human molecular science is the view that a human being is purely an atomic structure or technically a "molecule" (structure of two or more atoms). Subsequently, the human, viewed purely as a molecule (or atomic particle) can be studied as a physical entity, no different than any other molecular (or atomic) entity in science. Human molecular science, in concise form, is the scientific study of human molecules (or its derivative terms: human particle, human chemical, social molecule, economic molecule, human atom, etc. The chronological listing of the 75+ pioneers of this subject on the HMS pioneers page, gives a gist overview of the various issues encountered in this subject of study. The following three captions summarize the differing viewpoints of HMS:

Cartoon science? (43% believe they are not a molecule)		Hard science? (57% believe they are a molecule)
(NY Times cartoonish depiction of a human molecule)		(Sterner-Elser 2002 calculation for the empirical formula for one human molecule) (modern Thims-Hirata-Hwang human chemical reaction analysis)
Some maintain, strictly speaking, that a human is not a molecule, and consider modeling of humans as molecules to be either pseudoscience or humorous fun.		Some maintain, strictly speaking, that a human is a molecule, and consider the modeling and use of established scientific principles of molecular behavior, e.g. the laws of thermodynamics, to be a wealth of future scientific advancement.

Branches
There are three main branches of human molecular science: human chemistry, the chemistry of human molecules, human physics, the physics of human particles, and human thermodynamics, the thermodynamics of systems of human molecules or human particles.

Perspectives
There are generally three points of view in regards to the perspective of human molecular science:

Representatives
(a) The subject is a contrived anathema that does not apply to humans; there is an ‘unbridgeable gap’ of separation between the chemical world and the human world. (Wieland, 1810; Heilbroner, 1953; Fuller, 2005; Wojcik, 2006)
(b) The subject is useful for teaching, but a human is not, strictly speaking, a molecule. (Muller, 2006)
(c) The subject is correct view of what a human is. (Goethe, 1809; Thims, 2002)

The following 2006 interview quote by Venezuelan chemical engineer and chemical thermodynamics professor Erich Muller: [1]

“Obviously people are much more complicated than molecules—cartoon science is just a way to help someone understand something. One molecule may form strong bonds to another of that some type but I would hope that your decision to marry would be a little more complex than that!”

Muller's referral to human molecular science as a "cartoon science" highlights the ambivalence, or possibly fear (of academic disgrace or loosing tenure), common to many human molecular theorists, which explains why the subject is often perused after retirement (Adams, 1910; Darwin, 1952; etc.). What Muller calls a cartoon science, in interview, differs greatly from the hard science he uses, in practice, in in his 1998 Chemical Engineering Integration and segregation thermodynamics article "Human Societies: A Curious Application of Thermodynamics".
