INTRODUCTORY REMARKS 



G. P. Weinblum 



Institut fur Schiffbau der Universitat 

 Hamburg, Germany 



Ten years ago the International Towing Tank Conference held a meeting in 

 Oslo. At that time, I had the privilege of lecturing on the subject, ship motions, 

 before His Royal Highness Crown Prince Olaf now His Majesty the King. It is a 

 highlight of my professional career that today in your Royal Highness' presence 

 a team of gifted younger scientists will report on the impressive progress 

 reached in our field during the recent years. They will prove the well estab- 

 lished fact that we, in engineering sciences, usually overestimate what can be 

 accomplished within one year but fortunately underrate what can be done within 

 ten years. 



Now that your Royal Highness has graciously opened the session we shall 

 start immediately with our work. 



Our kind hosts have carefully included short curricula of the lecturers in 

 the abstracts. Thus the need for introducing the speakers to the auditorium is 

 eliminated. There is another reason why it is perhaps not so important to follow 

 this well established habit of introduction: although our young speakers have 

 already reached a high scientific reputation, their future is still more important 

 to our profession than their past. 



Calling now Dr. Ogilvie, the head of the Free Surface Phenomena Branch of 

 the David Taylor Model Basin in Washington, D.C., to deliver his lecture. It is 

 my pleasant duty to emphasize that during his stay as liaison scientist of the Of- 

 fice of Naval Research in London he has earned viniversal esteem and friendship.
