XXII PRESroENTIAL ADDRESS 



brotherly love ; I ask the experimenter not to be shy to ask such questions, for 

 they may turn out to be quite searching and may indeed enforce modifications 

 of theory. Again, I ask the theorist not to be shy to apply his theories to facts 

 with which he may become familiar only at this meeting; and the experi- 

 menter to try to enlighten the theorist about these facts, again in brotherly 

 love. 



Finally, I am convinced that quite apart from the direct scientific results 

 of the Symposium, our living together here for one week will cement bonds 

 of friendship and comradeship which will remain a force long after the 

 Symposium.
