  1. Last weeks topic: • -Understanding Base Concepts: • understand = being able to translate • knowledge = network of concepts • concept = name, context, definition, discussion, and examples • [1] L. J. Durak and A. Hübler. Scaling of knowledge in random conceptual networks. • Lecture Notes in Computer Science 2074, 976-985 (2001). • [2] A. Hübler, Understanding Complex Systems: Defining an abstract concept. • Complexity 12(5), 5-9(2007). • This week: • Solids / Fluids / Gases

  2. Solids, Fluids, and Gases • Solid: • rock, wood, water ice, dry ice (ball) • atoms are close, most rigidly packed and do not change • position => definite volume • elastic = returns to original shape after being squeezed or • stretched => definite shape • Liquids: • water, oil, clay, liquid nitrogen (vases) • atoms are close, densely packed, and change position => definite volume • viscous = does not return to original shape after being squeezed or stretched • => nodefinite shape • Gas: • vapor, air, oxygen gas, nitrogen gas • atoms are far apart and change position => no definite volume (N2 cannon) • viscous = does not return to original shape after being squeezed or stretched • => nodefinite shape • Simulation => phase transitions are sharp & energy is conserved

  3. Last weeks topic: • -Understanding Base Concepts • [1] L. J. Durak and A. Hübler. Scaling of knowledge in random conceptual networks.
