The  underlying  physical  laws  necessary  for  the  mathema.cal  theory  of  a  large  part  of  physics  and  the  whole  of  chemistry  are  thus  completely  known,  and  the  difficulty  is  only  that  the  exact  applica.on  of  these  laws  leads  to  equa.ons  much  too  complicated  to  be  soluble.
