Can Economics Afford Not To Become Natural Science?
  The 'Discussion & Debate' issue of this Euro. Phys. J. Special Topic volume is: 'Can economics be a Physical Science?' I would rather address a more general question: 'Can economics or sociology avoid joining Natural Science?' and argue that mainstream or core economics or sociology can not escape joining natural science.
