As the great physicist Richard Feynmanmentioned,itisthelastgreatunsolvedproblemofclassicalphysics.TheAmericanMath- ematical Society has listed the turbulence problem as one of the four top unsolved problems of mathematics.ItisalsooneofthesevenproblemsforwhichtheClayInstitutehasrecentlyannounced a$1millionprize. The powerful notions of scaling and universality, which matured when renormalization group theorywasappliedtocriticalphenomena,hadbeenmanifestedinturbulencepreviously.Therecent dynamical system approach has provided several important insights into the turbulence problem. However,deepproblemsstillremaintochallengeconventionalmethodologiesandconcepts.There is considerable need and opportunity to advance and apply new physical concepts as well as new mathematical modeling and analysis techniques. There is also an ongoing need to bridge the gap betweenthegrandtheoriesofidealizedturbulenceandtheharshrealitiesofpracticalapplications. Theturbulenceproblemcontinuestocommandtheattentionofphysicists,appliedmathematicians, andengineers. Several turbulence research groups in Florida collaborated to hold an international turbulence workshop at the University of Central Florida, May 19–23, 2003. The sponsors of this workshop were: University of Central Florida (Department of Mathematics, College of Arts and Sciences, andOfficeofResearch),FloridaStateUniversity,FloridaA&MUniversity,UniversityofFlorida, Embry Riddle Aeronautical University, and area industrialist Dr. Nelson Ying. The idea was to bringtogetherexpertsfromphysics,appliedmathematics,andengineeringworkingonthiscommon problemandpromotetheinfluxofexpertiseintothesubjectfromallthesegroupstothebenefitof allinunderstandingcomplexissuesofthisproblem.

My area of research intersects yours precisely in our recognition of the importance of a good numbersystemandagoodnotation,andouruseofthesamenumbersystem.Indeed,asIlookbackon myowncareer,myclosestcontactwithturbulence—andthiswas,asinthecaseofthisconference, amatterofinternationalturbulence—wasduringWorldWarII,whenIwasconscriptedtowork, fromJanuary1942untiltheendofthewarinEuropeinMay1945atBletchleyPark,breakingthe highest-grade German ciphers used for diplomatic and military traffic passing among the German government, the German High Command, and their naval, air force, and army commanders and U-boat captains. Those were indeed turbulent days, and I will say something about them in my remarksthisevening.Moregenerally,IwillreflectonthewonderfulmathematiciansIhaveknown during a career spanning more than 60 years, starting in British Military Intelligence, proceeding alongamoreconventionalacademicroute,andcontinuingtoday,thoughatagentlerpaceconsistent withmygrowingmaturity. 1.1 ALAN TURING OurworkatBletchleyPark,crackingthehigh-gradeGermancodes,waswonderfullyexciting,stim- ulating us to work tirelessly, over long stretches of time, buoyed by the intellectual challenge and our awareness of the importance of what we were achieving. However, for me, as a very young man — I started work at BP (as we called it) at the age of 18 — there was the thrill of work- ing with some of the greatest British mathematicians of that period, getting to know them well and enjoying their friendship and collegiality. They were absolutely free of any outward aware- ness of their intellectual superiority and treated their younger colleagues as equals — which, as cryptanalystsbutnotasmathematicians,ofcourse—wewere!Theyseemednottobeawarethat, howeveradeptwemightbeatapplyingmathematicalthinkingandperhapscertainveryspecialized linguistic skills to the job in hand, we had no mathematical knowledge and experience to match theirs.
