Development Center (our chief semanticist had us remove the nasty- 

 word warfare from their title) would come under the heading of 

 bragging about a relative. And after bringing myself up-to-date on 

 the history of the California Institute of Technology I felt there was 

 just nothing I could say. Even an amateur of science who walks 

 across a campus where such men as MllUkan and Mlchaelson once 

 tarried to think, feels as an art lover must feel when he walks on a 

 stone bridge across the Arno where Leonardo once set his mighty 

 sandal. The debt the nation and the Navy owe this Institute Is beyond 

 all calculation. 



The point was adroitly made, I thought In a booklet about Cal 

 Tech that Dr. Plesset was kind enough to send me. The booklet 

 contained a picture of a man on a bicycle as an Illustration of the 

 Institutes recreational opportunities. The man on the bicycle who 

 was unidentified In the caption, was Einstein. 



Dr. Plesset also provided me with a program of Symposium 

 events and I ran through It looking for a possible clue as to what I 

 should choose as a topic. Several arresting items caught my eye. 

 Listed was a paper on "The Second-Order Theory for Nonsinusoidal 

 Oscillations of a Cylinder in a Free Surface. " Another was on 

 "Three Dimensional Instabilities and Vortices between two Rotating 

 Spheres," and another on "Interaction between Gravity Waves and 

 Finite Turbulent Flow Fields." 



Well, I know when I^m out of my league so I decided to just 

 make a few First Order remarks on the mission of Navy Oceano- 

 graphy and how it is organized. 



First a definition. Hydrodynamics is not generally considered 

 to be oceanography but then neither specifically is anything else. 

 Oceanography as we use It is just an omnibus word for any scientific 

 or engineering discipline as it applies to the oceans. 



It is nothing new. In the American Navy it goes back at least 

 to our pre-civil war patron saint. Lieutenant Matthew Fontaine 

 Maury, who used his knowledge of winds and currents to help the 

 clipper ships set their famous world speed records. In Great Britain 

 it goes back to the famous voyage of the HMS CHALLENGER. 

 Benjannln Franklin took a lively Interest in it and so did Aristotle. 



But modern oceanography in the Navy dates from the christen- 

 ing of the NAUTILUS and the nuclear missile submarines that followed 

 it. Warfare had suddenly become truly three-dimensional. The new 

 mission of Navy oceanography was to see to it that the Fleet was 

 given the lnform:ation it had to have to insure its ability to operate 

 efficiently in this new and deadly area of under seas warfare. 



Before I tell you how we went about this let me say a few
