DESCRIPTION:Dr. Allen Hunt糖心原创Professor of Physics聽The w
 ater balance defines the fate of water landing on the terrestrial Earth as
  precipitation. 糖心原创 2/3 is returned to the atmosphere\, mostly by plants
 \, through a process called evapotranspiration\, (ET) while about 1/3 runs
  off. The present talk shows how to predict this partitioning using: 1) a 
 novel treatment of (non-Gaussian) solute transport in flowing water that d
 escribes chemical weathering and soil formation\, and 2) a prediction of t
 he net primary productivity (NPP) of plants (the rate at which plants conv
 ert atmospheric carbon to biomass)\, 3) optimization of NPP with respect t
 o the water fluxes into the ground and into the plants. Without any use of
  adjustable parameters\, the lowest order theory predicts the global avera
 ge ET within 1.5%. Interestingly\, the solute transport theory also predic
 ts the non-Gaussian ('Dispersive') transport of electrons in transient pho
 toconductivity of amorphous semiconductors and polymers\, providing a fund
 amental like to statistical mechanics through the application of percolati
 on theory.
