Rubber Elasticity Reconsidered

NOTICE
  • NEVER TRUST THE FOLLOWING
Rubber Elasticity
  • Elastic (stretchable) polymer chains of approximately infinite length
  • Approximately no characteristic length scale (except the UV-cutoff below monomer scale - Silicone rubber is transparent to visible light)
  • Tension relaxation is endothermic, that is, it takes heat from the environment as it shrinks
Scale Invariance
  • One of conformal symmetries
  • In economics, perfect competition concludes constant return to scale
  • In economies with such property, any exogenous shocks are soon absorbed
  • Wage stickiness and social discrimination are thought as imperfectness
  • Economists have called above property as "elasticity" for a long time
Gravity
  • De Sitter black holes behave like rubber lumps - endothermic contraction
  • Existence of specific structural length scale (as in solid crystals) may cause negative curvatures in certain energy levels
  • AdS-CFT seems to be ineffective for "rubberlike" matters
TODO
  • What does it mean the nonnegative constraint of interest rates in economics?
  • Action of relaxation on rubberlike universe is called quintessence, or fifth interaction. What is it?
