What does soft matter mean?

If you are not a "search engine", "spy tool", or "machine viewer" then you are a "soft matter machine".
To have a better idea about what is categorized as soft matter I recommend you to read following articles:

1.     M. E. Cate, Soft Condensed Matter, cond-mat/0411650.

2.     P. G. de Gennes, Soft Matter, Rev. Mod. Phys. 64, 645 (1992).

3.     T. A. Witten, Insights from soft condensed matter, Rev. Mod. Phys. 71, S367 (1999).

Text books:

Soft Condensed Matter by Richard A L Jones.
Principles of Condensed Matter Physics by P M Chaikin, T C Lubensky (sections 1,2 and 6).
Statistical Thermodynamics of Surfaces, Interfaces, and Membranes by A Safran.


Further reading:

Soft Matter Physics: An Introduction by Maurice Kleman, Oleg D Laverntovich.
Biological Physics by Philip Nelson.
Structured Fluids: Polymers, Colloids, Surfactants by Thomas A Witten.
Intermolecular and Surface Forces by J N Israelachvili.
