NUCLEAR NAVY

[Music] if you choose 24 people completely at random what what is the probability that at least two of those people will have the same birthday take a strip of paper give it half a Twist and join the ends if you cut the loop completely down the center will you have two separate loops or two interlocking ones given an unlimited number of ships all at one location each ship carries enough fuel to take it only halfway around the world all ships are capable of mid ocean refueling and all must travel at the same constant speed problem if All Ships must start from and return to the same point what is the minim minimum number of ships required to make a single non-stop Voyage around the world given a mechanical puzzle with interlocking Parts problem separate the parts without damaging the puzzle if these sort of things turn you on if you like working with your head and your hands consider this how would you like to be responsible for moving a 990,000 ton vessel over 125 miles on less than 1 oce of fuel sound challenging good the Navy would like to let you use your head and your hands in a fascinating New Field the phrase nuclear power means many things to many people to the Navy nuclear power means propulsion a way of moving a huge ship from one place to another efficiently quickly cleanly the Navy now has over 100 vessels powered by nuclear energy more are coming we need your help to run them as a nuclear propulsion officer you'll be working with the newest most advanced equipment available and you'll be helping solve many of the problems that led to the current energy crisis the Nuclear Navy offers is a man an unprecedented career in addition to an excellent salary and fringe benefits you'll be in a position of high responsibility making your own decisions you'll be teamed with highly professional Associates you'll have top drawer fully qualified subordinates men with brains and initiative you'll find them sharp demanding challenged lead you'll have a choice of Duty surface ship submarine or possibly Shore Duty as a nuclear engineer if you go to Sea you'll have the finest accommodations the Navy can offer remember this isn't just Navy it's Nuclear Navy there is a difference very few are eligible for the nuclear propulsion program if you're looking for a career not just a job if you can take the initiative if you like to think on your feet you may qualify no you don't have to have any Pride nuclear training just the aptitude the Navy will take care of the rest the Navy's nuclear propulsion officers program begins at officer candidate school at Newport Rhode Island you learn basic military and technological subjects such as seamanship engineering and navigation there you'll also get physical training and you'll receive basic Navy orientation and officer and doctrination and you'll be commissioned as an ensen in the Navy then we pour it on 24 weeks of nuclear power school in either California or Florida it's 5 and 1/2 months of pure academics courses are taught on The Graduate level you'll be studying Atomic and nuclear physics ordinary and partial differential equations quantum mechanics chemistry reaction kinetics heat transfer thermodynamics electrical engineering circuit analysis solid state devices Motors generators reactor equipment strength of materials Reactor Core characteristics you'll learn it all you'll think it's impossible but you'll do it anyway the next step in your training is 26 weeks of the nuclear prototype in either Idaho New York or Connecticut these installations are classified so we can't show them to you in this film the Prototype is an exact fullscale shipboard nuclear power plant here you learn the Practical aspect of operating the entire plant you'll be applying all your theoretical knowledge to a complex Hardware system and it's strictly a Hands-On operation after completing 6 months at the Prototype you're ready for Duty if you're interested in submarines you can volunteer if accepted you'll have five more weeks at New London Connecticut before being assigned to one of the Navy's nuclear subs otherwise you'll go straight to work either as a Shore based engineer or board one of the Navy's nuclear surface ships as a seagoing nuke CBO surface you'll be responsible for the entire propulsion plant from the reactor to the shaft your duties are far from Mere paperwork you'll be taking the reactor critical lighting off the plant standing engineering watches solving problems supervising repairs recommending modifications you'll be using all your technical skills to the fullest head in hands all the way your future if you're interested in Graduate Studies you might be eligible for the Naval Postgraduate School at montere California advancement in rank is historic ly rapid in the Nuclear Navy and you'll have an excellent opportunity for command only nuclear trained officers can command nuclear powered [Music] ships in all the world there's nothing like the Nuclear Navy the training and experience are unequal anywhere you'll be practicing your special interest in the fullest possible way you'll be working on the border of the state-of-the-art at the frontier of Technology if you like responsibility you'll get it fast you'll hold the responsibility and Authority for the supervision of a multi-million dollar power plant within a year of starting your training okay so you're obligated to serve four years but look at what you get it's like a solid year of grad school plus another three years of high level on the job training think about it the probability that at least two out of 24 people will have the same birthday is almost 50% with 50 random people the probability is almost 100% a sure thing this is one of those problems that defy intuition like assuming You' never qualify for the Nuclear Navy you may three ships each carrying enough fuel for half a round trip are required to make one complete trip around the world red white and blue start together 1/8 of the way around red refuels both white and blue leaving red just enough fuel to return home at the one quarter point white gives blue half his fuel using the remainder to get home blue now has enough fuel fuel to reach the 3/4 Mark but red has had time to return home refuel and take off in the opposite direction he meets blue at the 3/4 Mark they share Red's fuel which is just enough to get them to the 7/8 point where they are met by white who has enough fuel to get them all home it's a rather complicated puzzle of academic interest only especially when you consider that the nuclear powered vessel carries enough fuel for more than a dozen non-stop trips around the world the little experience in practice the mechanical puzzle is a breeze to solve it's the same with any problem any good head can hack it if you cut the Twisted Loop down the center you'll have neither two separate Loops nor two interlocking ones you'll have created a single loop with twice the circumference those of you familiar with topology will recognize the mobia strip an unusual surface having only one side and one Edge it like the Nuclear Navy is unique [Music]
