By soft subject (English softly condensed more matt) one understands condensed phases, which only causes itself one of the states of aggregation "firmly" or "liquid" assign let in physics. In addition count among other things

• Liquid crystals (uses in LCDs)
• Polymer melts and - solutions (like honey)
• Gels (e.g. God food)
• Polyelektrolyten (e.g. the absorber substance in diapers)
• Colloidal suspensions (ink, blood etc.)
• Elastomers (rubber)

In this material class numerous model systems are for the investigation of fundamental physical phenomena, in particular from the range of thermodynamics (e.g. Self organization, nonlinear material properties, phase transitions, the critical phenomena). Besides points of contact exist to biophysics.

These materials possess frequently surprising characteristics. A well-known phenomenon e.g. is. Driving sand, in which one sinks, if one moves, or pudding, over which one can run, in which one sinks however, if one remains standing quietly. Likewise exists material, which possesses Flummieigenschaften in ball form, but zerlaufen in the hand.
