IRON WARRIORiView from the topBefore I begin rambling on about other things I

would like to, in this third and final edition of fronWarrior this term. thank all the people who workedon the IW and made it such a great success. BRAVaIf the paper continues to grow in the fashion it has sofar, it won't be long before IW becomes international. Look out New York Times, WashingtonPost and the rest

our terms in order to keep the results reliable andthat we would advise our successors to follow suit.

J later spoke with the civil class representativesabout this development and they agreed to hold thecritiques out of class, if need be, in order to ensurethat program continue and to show the civildepartment that engineering students are indeedserious about the program .

While I am thanking people, I would like toexpress my thanks again to the executive - all thedirectors that make sure our pu bs run smoothl y andso on. I would also like to thank the classrepresen tali ves for wha t [consider, a job wflll done. Ithink on the whole, everyone did a good job BUT Jthink we all have some room for improvement. Forexample:

As we are all aware. the Engineering Society runsthe Course Critique program flach term. Usingcomputer cards to respond to a questionnaire andusing comment sheets, we all get achance toexpressour feelings about our courses and our professors,both good and bad. [recently received a memo fromthe Associate Chairman for Undergraduate Studiesin the Civil Engineering Department. Dr. Koewen,who stated that "due to previous inconsistenciesand the ad hoc mannerin which the course critiquesare administered, the Department of Civil Engineering is withdrawing its support for the program."Upon speaking with Dr. Koewen about the problem,he cited that there have been changes to thequestionnaire and the rating system in the last fewyears so that some of the results were suspect. Iagreed that there had been some inconsistencies inthe past but assured him that both myself and MarkLiddy (Eng Soc B President) would be adhering tothe same questionnaire and rating system during

I also spoke to Dean Lennox about the CourseCritique program . He pointed out that he has alwaysand will alwilys continue toendorse the program as 'it is indeed one of the most useful tools in makingdepartmental decisions on promotions and tenure.He also cited specific examples of professors whohad received several bad ratings and w ho since thengreatly improved in their teaching abilities. Whenasked about the questionnaire itself, the Dean notonly endorsed it but reminded me that he was one ofthe individuals who helped put together thequestionnaire. The main problem in his mind thatwe currently have with the program is that we needto get greater I'esponse from the classes for thecritiques. I pointed out to him that that had been ourmain thrust with the program all term long. Heconcluded that "the course critique program washere to s tay and would continue to be a fact of life inthe engineering faculty". So where does that leaveus? Well, fill out those cards

One final note: Rememberall thefervourab outthechange of work term sequencing for the 8 monthstream? Recently in an Undergraduate AffairsCommittee meeting, Dr. Peter Roe, the AssociateDean, recomme nded that the proposed streamchange be indefinitely shelved due to oppositionfrom both the s tud ents and someofthedepartments.

Doesn't ittrain us to work under continuous pressure? Yes it does. Forthe few of us who will somedaymake important decisions daily,the workload is beneficial. However it is difficult to justify theheavy workload on this basisalone.

Combined with this heavyworkload, the competition formarks promotes docility. Eachterm someone will fail. Not manyof us want to fail. So, we do whatwe have to to stay in the system.Our focus on marks becomes

more intense for each new classas admission standards rise.

As a result of this lack ofeducation we have little appreciation of the social impact of thetechnologies we work with. Howcan we, as engineers, be expecled to find appropriate solutions without understandingt he human side of the problem? Itis this lack of a better groundingin humanities that often places usin an adversarial position withthose people without a technicaleducation.

In short, our educational system lacks quality. Granted, itdoes teach us to learn underpressure and to methodically

The doors that thispiece of paper opens will alwaysbe the biggest reason to put upwith an engineering education.But the enginer in g educationwe endure to reap the finalrewards is defective.

emoe speaksAs the end of this term ap proaches rapidly , I would like tolook back reflectively upon another busy term. With this term,A Soc saw a fun-filled Orientatlon, a number of great engineering pu bs, the defeat ofQEMF, the APEO conference andengineering week and weekend.The Orientation this fall was, tosay the least, an arresting (cardiac???) experience. The eventswere well planned and attendance was great from probablythe most energetic frosh classever to hit the University ofWaterloo.A man who has been behind thescenes of virt ually every pu b inthe past few terms should not gowithout reco nilion. At this lim1 woultllik e to con gl a tu la le oursocial evenl mastermind, TonySwierkot, as well as everyonewho helped or attended theseevents.

As everyone knows by now theQEMF proposal was defeateuduring this term's referendum.Although it was defeated in ourstream, the awareness ofuniversity underfunding was greatlyincreased among the studentpopulation, which is, in amannerof speaking, a success in itself.Since the proposed solu lion is notbeing implemented, the problemwill still exist and alternativesmust be approached.

During October we hosted anAPED undergraduate conferencehere at Waterloo. Another wellrun event, thanks to the group of

enthusiastic organizers, whiChproved to be both educationaland a large pat on the back forengineering at Waterloo, sincemany of the other universitiesinvolved expressed their admiration of our well run society.

As usual, the engineeringweekend and week came offwithout a hitch, with great participation in numerous eventsrun by lots of enthusiastic organizers. The semi-formal ending engineering week was a funaffair for those people whoattended, but unfortunately, toofew attended. This poor attendance has lead to a new format fora semi-formal event in thesummer which will hopefully beappealln to more people thissumm e r.

Looking back, I think that eachand every member of our societyshould congratulate themselvesfor their efforts of this term.Hopefully , this summ er will

see increased participation bothin ENG SOC and in our eve nts,and t his means all of you froshout there (the hard term is overand done now ).

As for those whiners graduating this spring, take note ofthe fact that you will be in B Socand then you will realize howgood things really were in A Soc.(Editor's note this is justDemoe's cheap shot at me forbitching so long that he wrotesomething .. .J

IRON WARRIORAssociation of Professional Engineers ofOntario - the A.P.E.O. A number of trees havegiven their Ii ves in order that we could pass on a

bit of information on the APEO to you in thisand other issues. Outside of understanding thatregistration with the APEO is mandatorybefore one can practise as an engineer, howmany of us have thought about what the APEOstands for (and I don't mean the letters), andwhy it is there?

Engineering is a self-regulating profession,and necessarily so . This is due to the fact thatour work is largely esoteric; the majority ofpeople do not possess our special skills orspecific knowledge. This is coupled with thefact that engineeringactions and decsions havefar-reaching effects on everyone's life in ourincreasingly technologically-oriented society.Realizing this, Society through its elected representatives allows engineers to have theresponsibility of regulating themselves, implicitly accepting that engineers are the bestjudges of their own competence, integrity andloyalty to the public.Let's dwell for a moment on the term "professionalism". Professionalism implies that skilland knowledge should be applied with honesty,integrity, and effort. Professionalism implies aconcern for public welfare, and a commitmentto quality in one's work. Professionalismmeans accepting the responsibility conferredupon us by society to serve as the vanguard inour efforts to keep pace in a fast-changingworld.

Walter Light of Northern Telecom said in arecent speech:I t is not very apparent that Canadians -

ditorialinside and outside of government - do not, ordo not want to, understand that tomorrow'sjobs, their continued high standard of living,the health of the economy and the real fut uresecurity of the country rest upon the successor failure of our technologies, and /orourskillto create and develop them faster and better

than other countries."In this scenario, professional engineers mustassume the mantle of leadership. We are thepotential architects of Canada's industrialfuture. We must recognize that we have the responsibility to lead technological advancement, to improve our economy and therebysociety. It is our responsibilit y as we've alreadyestablished that the nature of our work isforeign to society in genera l - thus nobody elseis able to lead us.Many of you must be wondering by now justwhat all this lofty talk has to do with usanyway. Well, as engineering students at theUniversity of Waterloo, the best school in thecountry, aren't we soon to be at the forefront ofthe Canadian technological revolution?Shouldn't we start preparing ourselves toaccept our responsibility to provide leadership? Shouldn't we be cultivating our professional qualities by interacting with the university community., getting involved, and developing the necessary communication and leadership skills? If .so, then why are so manyuniversity and engineering society events andendeavours characterized by apathy ratherthan enthusiasm? We should try to avoid taking

Speakers forthe layman

With the work term approaching it's time to think about how tospend those megabucks that we(those of us who find work) willbe earning. One of the ever popular student purchases is astereo. Increasingly the world ofhi - fi is becoming cluttered withglossy pictures and intimidatinglingo. lt is more and more difficult for someone to buy a goodsounding system without get tingburnt.

There are dozens or interrelated variables that are considered when designing a speaker system. It is impossible tosimultaneously maximize all theparameters. This fact combinedwith the fact that no one knowswhat perfect reproductionmeans, has lead to a great varietyof speakers available today.Putting the Pieces TogetherThere are many devices avail able for converting eleetr'kalsignals into sound. By far themost popular is the cone speaker .II consists of four main elements.They arc the diaphragm or cone ,flexible edge, voice coil andpermanent magnet. A metalbasket surround s these clements.

This article addressed only onecomponent of a system ,speakers,but shou Id provide a basic understanding of them. It is intended tohelp non-audiophiles begin nav igating through the often intimidating jargon jungle.

The diaphragm is usuallymade of paper. It creates soundwaves by oscillating in and out. Aflexible edge holds the cone inplace while allowing free movement. The voice coil and permanent magnet together drivethe diaphragm. The electricalsignals that are the audio information travel through the coil.The diaphragm movement iscaused by the electrical signals.An electrical current in the coilinduces a current in the magnet(just like we learned in IB E&M).An attraction or repulsion force,depending on the direction of theelectricity is created by the twocurrents. The diaphragm is at tached t o t he coil and movesaccording to the forces on the coil.It is centred on the magnet by aflexible structure called a spider.The amplitude of its motion iscontrolled by the change in theamplitude of the current.

When youremovethecoverofaspeaker you will see at least twocones or drivers . The reason forthis is simple. We can hearsounds from about20 Hz to about20 kHz and there isn't a driverIhat can produce quality soundover th is ra nge.T he lo we r por ti on of t he ra nges ha nd l ed b y th e woofe r. It i s th elargest driver and produces thebass notes. If there is a mediumsize driver, it is ca lled the midrange driver. The highest tonesare produced by the tweeter.Inside the speaker is a fre

tjuency crossovel' net work. Itsorts the audio frequencies anddirer.ts them to the appropriatedrivers. The frequency whereone drivp.r is near its upper limitnnd another is nearits lower limitis known as the crossover frequency. Actually the r.l'ossoverfrequency is a range and naturally varies from model to model.As mentioned earlier t he woofers have the largest cones. Theyare big because they must pushIflfge amounts of air to producenormal sound levels. This is dueto the faGt that our ear is not assensitive to lower frequenciesand they have to be more intensethan mid-range freq uencies.There art' several design stl'ategies In increase the amount ofacoustical power produced by a\ oofel'. The fil'st is to make awuofer with a large diameter.Alternativelv, the diameter canbe kept small but the cone travelon each oscillation can be increllsed. The final alternative isto use more than one woofer. Mostbookshelf speakers utilize in creased cone travel or throw toimprove Ihe bass response. It isImportant to remember Ihat bigwoofers do not necessarily generate more bass.

The next question is how muchbass is enough? We can heardown to about 20 Hz. A wooferIhat even comes dose to this limitis quite expensive. Most musicextends only to 50 or 60 Hz andspeakers with this kind ofresponse are adequale for mostlisteners.Jn IllCiny ways I he tweet er is anexact opposite of the woofer. Inorder to vibrate up to 20 kHz thet\,eeter must be small and light.

It may seem that a small diame tertweeter would have difficultypushing large amounts of air toproduce high sound levels. Actually it's high frequency andlight weight make it a moreefficient radiator than the heavylow frequency woofers.Tweelers often have domeshaped diaphrogms to increasesound dispersion by radiatingsound waves at wider angles.Some designs may use horns orshallow cones to assist dispersion.Enclosures

The drivers, whether tweeters,woofers or mid -ranges, arehoused in a cabinet. The cabinet's main purpose is to improvethe sound levels of the woofer.When the diophragm vibrates itproduces a sound wave from bothsurfaces. A woofer 1110 ing outward creates an area of highpressure in front of it and an areaof lower pressure behind it . If itstands alone the air flows fromthe front around the rim to theback. This reduces the intensityof both waves and thus the intensity of the sound.The cancellation problemdoesn't exist at higher frequencies because the diaphragmmoves too quickly. The solutionto this problem is to baffle -extend the rim of the woofer.There are three major types ofbaffles or enclosures.Sealed enclosures prevent therear wave from escaping and areof two sub-types: infinite baffleand acoustical baffle. An infinit e baffle enclosure is used wi th alarge diameter short th row woofer. The enclosure contains acoustical insulation (fluff) to absorbthe rear wave. It requires a largeenclosure to prevent the trappedair from acting as a spring redut:i ng the throw a nd response ofthe woofer

Nov 29, 1982 4

An acoustical suspension orair suspension speaker has asmaller enclosure and wooferwith a larger throw than aninfinite baffle encloSllre . Thewoofer cone is attached to thebasket with a flexible half-roundtype suspension to permit longth,ows. Like the infinite bafflethe real' wave is absorbed 'byacoustical insulation.

Dented enclosures, also calledbass reflex, tuned port or phaseinverters increase the bass byducting the rear wave forward.By carefully placing a tube in anenclosure (mostly t rial and error)the rear wave will be in phase butlate. This delay increases theintensity but doesn't affect thequality of the sound. Front andrear waves don't cancel al higherfrequencies because the ports aredesigned to emit only the lowerfrequencies.

The third lype of enclosure is ahorn enclave. A horn dispersessound more efficiently than asealed or vented enclosure. Thedisadvantage of a horn is that ithas a cut off frequency, belowwhich it can not reproducesound. This frequency dependson the horn's geometry. Thelarger I he horn the lower the frequency it can reproduce, bUI toreach 40 Hz a horn would have tobe 5 metres in diameter and 3 to 4metres long.Specifica tionsSpecifications abound in theaudio industry.

PEOConference"In thecomplex world of today ,what is the place of the engineer?How do others perceive the roleof the engineer and how weH doeshe fill it? Is our educationalsystem adequate for producingengineers to fill this role? Whatdo engineers think of their work?How do they communicate withthe rest of society?To whom doe she owe a duty and what is itsnature? How can engineeringstudents prepare to fill their rolein society?" These were the questions, presented to the delegates,by Chairman Dave Craig, at theFifteenth Annual Association ofProfessional Engineers of On tario - Undergraduate Engineering Societies (APEO-UES)Conference, held from October29-30. The theme of this conference was "The Social Impactof Engineering".Thirty-one engineering students representing nine differentOntario Engineering Schools andseven APEO delegates spent"Hallowe'en Weekend" listeningto various speakers addressingthe topic of the social impact ofengineering and partaking of theimpact of social engineering.Friday afternoon was a sessionopen to the engineering studentsat the University of Waterloo,Grant Boundy, P.ENG., Assistant Registrar for the APEO spokeon the procedure for registeringfor the APEO. He discussed thenew compulsory ethics exam andsuggested reading material forstudy. Various literature was

available for those in at t nd anceA bdef question period was heldand of course the question aroseregarding equating six workterms to one year's experienceupon graduation. Mr. Boundysuggested that a greater pushfrom Waterloo Alumni as opposed to Waterloo Undergrad uates would be needed. However,presently the APEO is very firmin the attitude that work term experience is insufficient in devel oping the technical maturity required.

The weekend for the conference delegates began Fridayevening with a dinner. Thespeaker was Mr. A. Kobelak, P.Eng. who is the Immediate PastPresident of the APEO . Mr. Kobelak spoke on the nec essity ofengineers being involved in thepolitical process, from municipalto federal levels. He was pleasedto see attempts, spec ificallyQEMF, made by th e undergradsto change their environmentthrough the political process.Saturday morning's sessionbegan with a speech made by Professor Sally Lerner of the De partment of Man EnvironmentStudies at UW. She spoke on "TheSocial Impact of EngineeringProjects" . Ms . Lerner suggestedat the start of her talk that"engineers have always beencaught between science andSOCiety." t was her opinion thatengineers are indifferent to un forseen effects on societ y and unintended consequences of theirwork. However this is due to lackof formal study of the effects ofthe r work. She felt that engineenng education trained students to be first rate technicians,not responsible engineers. This

~ e a d s to a. fear that perhaps engmeers ill not question whatthey do, they will do as they aretold . Hence a problem of assemlbly line engineering arisesallowing the engineer to neglectthe social effects of their projects. She suggested a need forl wo governing bodies {or makinengineers and scien ti sts more responsible: she recognized thatone must come from within theengineers and that a governingbody external toengineeringandscience must also be sct up. Thislattel' body would have to beinformrd about engineeringwork in order to function prop erly .Dr. Bill Lennox , Dean of Engineering at UW then lead a discussion on "The Impact of theFunding Crisis on EngineeringEducation". He discussed fund-

ing and various sources offunding. Jeff Cox, President ofEngineering Society "A", alsospoke on the QEMF referendumwhich was defeated two daysprior at UW. Gus Rinella, a U ofTdelegate talked about the pos- itive results of t he addtional $100fee that U of T students pay .The afternoon speakers wereDr . J n Carr, Director, Engineerium, Niagara Falls and Dr.Tom Brzustowski, VP Academicat UW."The Engineerium - DirectCommunication with the Public"was the topic of Dr. Carr'saddress. He spoke on the newEngineerium and its role both as amuseum and a science centre.The theme is to preserve the past,think on the present, and toproject on the future.Dr. Brzustowski discussed"The Social Responsibility of theEngineer--. t was suggested thatwe as engineers are unique asprofessionals because our work(and failures) are highly visible.We cannot bury our mistakes likea doctor.

The idea waspresented to "A" Society council,under Don Heath's reign, and wasgiven approval. The result of thisapproval was that on March 290fthis year, Waterloo "A" wasselected as the host of theOctober '82 conference: theme"The Social Impact of Engineering"..Before leaving campus lastwmter, we had to procure accommodations for the delegates. This

was not an easy task as most ofthe larger hotels were booked bySkate Canada. But the ValhallaInn could squeeze us in and thatgave us the footing we needed toget started.Several meetings were heldover the summer between DonHeath, Jeff Cox, Brian Demoeandmyself to establish a timetable,director's responsibilities andthe required funds and speakers.The APEO executive wasn't

formed until the first week ofSeptember. At that time we had abetter grasp of the situation andwe weren't scattered throughoutthe province as we had been in thesummer. Some directors volunteered and some were appointed,but the breakdown was:Bill Lennox / Jeff Cox - Hon -

I have heard nothingbut rave reviews from the APEOreps and engineering societydelegates, which I can onlyassume is a vote of confidence forfuture programs.

However, it was only throughthe co-operation of such peopleas Dr. Wright, President UW, Dr.Lennox, Dean, the APEO representatives Dr. B.

ngineering and the Occult A fine article in February'sIEEE Proceedings describesmicroscopic scale experimentsusing optical interferometry, adual thermistor transducer. andan electronic random event generator. This last one, after anaccumulation of a large data base,has indicated a significant shift inexpected results. The authorpoints out several possiblesources of error, but the data isremarkable for its consistency.

No field of scholastic endeavour has been more maligned, misinterpreted or abused than reosearch into psychic phenomena.Much of this can be blamed uponthe fact that this often deals inaesthetic evidence; impressionsmore commonly than analysiswhich are often coloured bystrongly subjective and numenistic overtones. All manners ofsensationalists, con artists andlunatics have abused and fantasized occurences and results ofresearch have been almost uniformly rejected by the scientificcommunity.

All through t his history clouded in doubt and suspicion one cantrace a pattern of legitimateattempts to understand and evenapply these phenomena. Thequestion remains: Is there enough evidence, after hoaxes andlunacy have been removed fromthe evidence to justify researchin the field?

The study of the unexplainableis as old as man himself. Rel-

IglOns of ancient societies areliberally laced with formalismsbased on psychic phenomena.Numerous examples can be citedfrom the classical civilizations ofEgypt, Greece and Rome. Takefor example the Delphic Oracle,which was consulted by theancient Greeks in all manners ofdecisions. from curing diseasesto locating new colonies. Aristotle, who has been classified anempirical philosopher, examinedcausal links in prophetic dreams.The Bible is also well endowedwith psychic processes, a lmos tas a matter of routine. Virtuallyevery ~ t e g o r y of effect on recordcan be found there in one form oranother. Accounts of psychicphenomena appear frequently irtmuch of the Christian literatureup to the Reformation andbeyond.The first scientific observations seemingly. from Sir FrancisBacon, originator of the "scientific method", appear near theturn of the 17th cent ury.

world of science and technology,, where real problems are modelled and solved analytically.The area of ethics is mJIr.h j p c rdefined and cannot be laiddown in terms of "Thou shalt" or"Thou shalt not

Ethical questions are usuallyin the form of a dilemma; "whatshall r do?" Engineers often haveconflicting obligations to theemployer and to the public (or toth e ir consciences). The obligation to the em p loyer as an em ployee or a consultant is clearlydefined, whereas the engineer'saccountability to the public is alittle more difficult to pin down.

The engineer is responsi ble forthe public safety, as he sees it. Itis when these two obligationsconflict that di lemmas arise, andth is is where the code of et hics isrequired.

The problem in training potential engineers is to ensure thatthey not only know, but feel thiscode . It is on ly rare ly somethingthat ca n be learned on a workterm. since the student is seldom

actually responsible for hisactions. It requires a "baptism 01fire , so to speak, and thepotential engineer is not a professional until this occurs.

The students at UW have beenworking towards having our probationary period reduced to oneyear, since our last three workterms are often engineering workunder profess ional gu idan'ce, butthe crux of the issue is that thest udent engineer is not responsib le for his actions, w hereas thegraduate engineer-in-trainingmust be.TheAPEOislook in gat waysoffurt her ensuring this "e thicaleducation". One idea currentlyunder cons ide ration is requiringa ll trainee engineers to keep ajournal or notebook. to be evaluated along with their admissio ns at the end of the trainingperiod.

On the roadycling across Europe

Two of us started in Amsterda m . We'd brought out bikes withus, but it seemed to be a runningjoke all over Europe . . . How didyou get here? "By bike.Where are you from? Can

ada . . . which invariablybrought peals of laughter. Thesame two of us finished in Am -sterdam 3 2 months later, 2800poorer but a lot richer .Eigen, my companion (nick-name), was a graduate mechie, sohe had lots of time . There were nojobs for mechies last spring. Thetwo of us managed to pack sleeping bags, a tent, tools, spare partsand a minimum of clothes intotwo saddlebags and 1 carrier bagon each of our bikes, and then wehit the road.

Our first 5 easy days took usalong the coast and we ended upin Lille in France, just past theBelgian border. From there wetook a train to Paris and caughtthe Paris-Lisbon express. That'swhere the show really got on theroad.I did have some problems withmy bike in Lisbon and had to seekout a bike s hop . It was a goodthing too, because it must hav ebeen one of the few in all of Portugal. At least we knew whereone was to be found. From Lisbonwe cycled leisurely down the Atlantic coast towards the Algarve.The Algarve is the tourist spot inPortugal, with a virtually con -tinually warm climate andeternal sunshine. The coastline isdotted with little beaches (andbi ones too), between tow rincliffs and marv elo us crystal clearwater. It has become the newestregion, the place to go for thecrazed RunSllllkers of nC)It hC'1'nEurope.The Algarve is a long way fromLisbon though, and ev(>n thoughthe tourists crowrl along thiscoost, that doesn't mako theAtlantic any less impressive. It ismerely undeveloped. Alentejo

province is the poorest in Portugal, and the prices are evenlower than the fantastic bargains available elsewhere. Thecliffs are just as high, the beachesjust as big, but they are emptier.Some appear to be virtuallyforgotten . .

One particular town sticks outin my mind . When you first rideinto the main part of Odeceixe,the vision is not impressive. Butride down to the beach, a littlefurther on, and you've hi tnRradise . Another humons: ous,beautiful beach, with all the freecamping imaginable , and a tinyvillage with a coup le of restaur-ants. Our stay there provided, inaddition to the usual cerveja(beer), an introduction to thelocal firewater, a distillate of theremainders of the wine pressingprocess .

Since this portion of thecountry is deserted, our communication with the nativesmade life interesting. The secondlanguage in Portugal is French,and in this region, there weren'ttoo many who cou ld handle eventhat. Hands and feet proved to beuseful though.

The eating and drinking inPortugal, in addition to beingcheaper than anywhere else inEurope, is some of the mostincredibly good tasting that I'vecome across.

right out on the promontory,which was later converted into ayouth hosteL but preoccupationswith bike problems prevented usfrom biking out there to visit. rn-stead we holed up in one of thecaves in the cliffs east of Lagosand vegged out for a while. Thatwas pretty easy to do under thecircumstances.We went throu gh a similar sortof routine near Faro, the largestcity on the Algarve coast, beforewe headed forHuelva in Spain. Inaddition to finding considerableproblems in exchange of Portuguese escudos for Spanishpesetas (don't exc hange anymore money than you need inPortugal) we found the city ofHuelva a dingy, depressingplace, so we jumped on the firsttrain out of Spain.That of course, is easrer saidthan done. Firstly, there is thewell deserved repu tation of theSpanish train system. Then tocompound matters we had to payall kinds of surtaxes on top of ourrailpasses because it was rightnear the time of the World Cup inSpain. Definite bad news. Theyskinned us for everything theyco uld, so we got out as fast as wecould. It took us fully two days toget to Port Bou, the little borderpoint on the Mediterranean between France and Spain, and itseemed like forever.

From th ere it was a 6 day ride"along the Mediterranean cost toSan Remo in Italy. Sometimes wecovered quite a good distance and) remember one da in particularwhen we covered 130 km in spiteof a fair headwind. That's calledearning your dinner.

We found the French, particularly when you get away fromthe coast a little bit, quitefriendly. They appreCiated ourattemp ts to communicate, andone evening, after having had afew brews in one particular pub,the bartender plopped a roundont he t ab le "on the House". He thensaw to it that our bikes werebrought in, he closed the shop,and then took us upstairs, fed usand then we had a party with himand a few of his friends. It was notas if it was an everyday happening, but it was a nice touch.

Except for that one incident,we spent all our nights in Francecamping under the stars. Franceis emptier than one might expect,esp,ecially away from the coastline.

We had some minor bikeproblems in northern Italy, butthere, of all places, parts wereeasy to get. From San Remo wetook a train across the top of theboot of Italy to Trieste, and bikeddown into Yugoslavia. It was myfirst trip into a communistnation. but we couldn't see anydifference between it and itsneighbours. Once we saw a cophassling somebody, but thatlooked like home to me haveyou ever been to Sauble Beach?The ride down the Dalmatiancoast and to Dubrovnik was awesomely beautiful. but I'd neverbike it again. It is a verymountainous coastline. Theroads are very narrow and theyhave no gual'drails. The dropsdirectly beside the road wereoften several hundred feetstraight down and the busdrivers would often careen theirvehicles by us at terrifying vel-ocities with inches to spare. We

also happend to arrive in a heatwave . One day we figured thatwe'd each drunk 8 litres ofliquids, and in Yugoslavia youcan't even buy bottled water; allthat is available is that carbonated stuff, which only makesmatters worse. I tried drinkingthe local water once, and had theruns for 3 days afterwards for myefforts.We camped free in Yugoslaviatoo, in spite of the fact that we'dheard you can get locked up for it,but nothing eventful happened inthat regard. From Dubrovnik wetook the ferry to Corfu, thenorthernmost island of Greece.Standard fare for th e backpacking crowd there is to rentmopeds and go tearing aroundall over the island. I wouldheartily recommend this routine.We took a couple of days restfrom the bicycles and terrorized not a few old ladies on theirmules. In spite of th e fact thatCorfu is the least Greek of theplaces we visited, and ratheroverrun with tourists too, it wasthe cheapest place we found inGreece.

We left our bikes on Corfu, tookthe ferry to Patras on the mainland, and a train to Athens.Athens we found to be a large,extremely dirty city with verylittle in the way of attractions.We took off on one of thenumerous little ferries fromPiraeus, Athen's port, to los, oneof the more well known islands.

los in fact is so well known thatthe letters of its name might justas well stand for Irish, Others,and Swedes. It seems that 8o %o fthe people on the island areSwedes. The island is one hugesuccession of singles bars, and acommon sight just at closing timeis couples exercising theirconnubial rites in the middle ofthe street. Nobody every accusedthe Swedes of being bashful.

The Greek police had recentlybegun to crack down on toplessand nupe bathers, but that didn'tseem to dampen too many spirits.

From [os, we took anotherpathetic little ferry to Crete, thesouthernmost island. It is a largerisland, and in spots it is overrunwith tourists too. If you throwyour kit on your back, head fOthe southwest coast andgetoutofthe towns though, it is deserted. . . and beautiful. Wespent quite awhile living in a cave, once againjust vegging out.

After we got back to Corfu wespJi t up for a while. Eigen visitedhis girlfriend's relations inYugosiavia while I toured bytrain around central Europe. Icertainly had no trouble meetingpeople enroute, but I sure wouldnot have wanted to cycle alone.

We'd had ' our bikes shippedfrom southern Italy to Innsbruck, and my part ner got the bigidea that he wanted to ride upthrough Brenner Pass, one of thehighest in the Alps. f you're everstupid enough to tackle something like that, get a bike with 15or 18 gears to make sure youhave the low ranges necessary.We ended up alternately walkingand riding. t was cold, too, evenwith all our clothes on.

On the Italian side the road hada lot of switchbacks, and evenmore potholes . Suspense isriding along behind somebody ir.a dark tunnel. as he gruntsUMPH and OOH at everyunseen pothole. Agony is being',e lead rider .

When we got back to Innsbruck we decided to take a sidetour to Switzerland and hungaround Interlaken for a while.There are lots of Americansthere, but it is still an impressiveplace.

After we'd shipped the bikesfrom there to Stockholm, we leftthe bikes a while again and took amonstrously long tour throughFinland up to the Arctic Circleand back down a Norwegian railway. The ride from Narvik toOslo took days . . . it must havebeen 2 2 or 3 days, [ can't reallyremember anymore just for-ever.

Back in Stockholm we visitedwith some Swedes we'd met inPortugal and then took off withthem . to axjo in southernSweden for a festival. TheSwedes like to drink like fish, andthis festival was no exception, inspite of alcohol prices more prohibitive than even ours here inOntario.I'd had a workterm in Copenhagen quite some time ago, butwhen we went back to visit, I

didn't find a soul I recognized.The airline gave us a good scarewhen we ca lled in by tellin g usthat all flights were booked outfor a month, and by this time wewere financially over a barrel.After 4 days of riding andcamping in the rain, we werethoroughly annoyed and ca ught atrain back to Amsterdam, wherewith a piece of good luck, wegot aslot to come back home the nextday.

Am I a good cyclist? I didn'tthink so when I started, but I'mlots better now. We tended toseldom push it more than 100 km.a day, but that is enough. If I wasto do a bike trip in Europe again, Iwould avoid this circularrouteofbike / train / bike / train. I'd start inone spot, bike somewhere andtake a train back.

Some places we had no hasslestransporting bikes. Most placeswe had at least some hassle, butthere is a great deal of inconsistency from one nationalrailway system to another. InHolland, you can wait as long asthree weeks to ship a bike. InFrance the wait is only 4 or 5days. [n Italy it can becomerather expensive . Curiously thecountry with the most problemridden rail system , the Spanishsystem. posed no problem at all.

One certainly loses track oftime on such an expedition, and Ihad some difficulty adjustingwhen I got back . After ridingyour bike through all kinds ofterrain in fantastic weather itwas hard to come back to reality.Riding in the sun with the windsoaking up the sweat is exhilarating, to say the least. InYugoslavia we once went 6 dayswithout a shower. We took a lot ofswims along the route, and wereliterally glistening with salt, butthat was part of the feeling.

another letterTo the Editor:I am extremely disappointed,angry and ashamed to read thefeedback from the QEMF Referendum in the las t publication. Iam sorry to see the sad state ofmind of th e Mech and Elecstudents who seemed bent ontelling the world all about theirdire disappointments. I amshocked at the one sided implications of the article MandateDenied", and at the inconsiderateattitude of Jeff Cox in light of theresults .l should also say that I ama bit mad at the student whodared to even state that his fellowstudents who voted NO , arenothing but asses . I suggest hetake a good mirrored look atself. To think that we could eventually be working together aspr ofess ionals scares the hell outof me. All these shameful revelations makes me think thatmaybe, just maybe we are truly abunch of egotistica l, immatureindividuals w ho care little foranyo ne but themselves.I t hi nk tha t one of t he QEMF'sdownfalls was to assume t hat beca use peop le in high s ta tus, inpar ti cul ar Dean Lennox, had supported the idea, the majority ofengineers wo ul d con fo rm It ismy opinion that Dean Le nn ox,apart from other reasons, had tosuppor t the YES s ide. However,it was abhorr ing to see theblata nt and public support thatLi ddy, Cox and the Eng Soc executive gave to the YES side. Tome this was usurpat ion of power.It accomp li shed lit tie; it showed adisgrace for th e posit ion theyheld, an d it w,as a di sregard forfairness to all t he peop le t hey represente d. Mr. Cox et al s houldstand back a nd look at th e damage they did, and a re co nt inuingto do, to a supposed ly cohesivegro up.

voted i '0 because I felt the proposal. as it stood, was too shakyin its construction, and thusfailed to answer man:.. importantquestions raised by the NO committee. I agreed with the prmciple behind the idea . However,instead of dealing realisticallyaboul the possible intention, theQEMF commi ttee went out toconq uer Goliath . 11 was un

likely that they would havesucceeded since thev were noDavid and they had neither asling nor stone.We should realize that this wasa democratic political process.

Each person was en titled tosupport the view(s) of any individu al or group, for whateverreason(s). Therefore, irrespective of the irregularities of theQEMF proposal , of the tendency to isolate particular sentencesand paragraphs , of the abstainment from voting the fact is : Avein was touched in the 45%eng ineers w ho sa id NO I can'thelp asking all who were disappoin ted , what wou ld it have beenif the voter turnout was 100 ,a nd the YES got 100%1 Would itbe a referendum? or just anapprova l process? Commonsense te lls me that a referendumn that hypothetical case wouldhave been use less.

As Jeff Cox s ta ted , the under-

funding problem won't go a, ay .However , up to this point, thistopic has been talked about longand hard enough . Any moremention of this idea will eitherprovide an indifferent responspor add volatile fuel to an alreadyburning fire. Again. think of thepossible damage that may behappening.I suggest that the idea ofmeeting with 0 CO 1MITTEEmembers in order to seek alitrational suggestions be postponed. One can't help bu t wonderwhat will be gained. That is,apart from appeasing and indirec tlv coercing the 0 membersinto' the YES camp. I do think th ata careful re-evaluation of thebasic structure and aims of theQEMF proposals would eventually be undertaken over thenext four to eight months. How ever, to be e ffective in its address to the underfunding problem , the job should be done by aninhomogeneous group of indiv iduals who represent the different views of the majority. Inthis way, a well thought oul, lesscontroversial decision will beattained. Maybe then, a questionnaire (ins tead of a referendum) wi ll prove to bean effectivefeedback and the final vote wi llon ly be an approval process.S imon P. Bi rch , 2B EE

Daryl Diamond, 4A Electrical,has accomplished much in hisfour years at Waterlo o. He hasbeen involved in technical societies, deba ti ng a nd rugby as wellas the standard fare of workterms and academics.

At Moira Secondary School inhis hom e town of Belleville hetook three years of e lectronicsand was the schooJ'sou ts tandingscience student. As a result ofthis exposure to science, electronics and computers, hos onlydifficulty in first year was thelarge workload.In his first work term, Darylworked for a chemistry professorat R.M,e. in Kingston co nstruct ing a power supply for a laserbeam, He en jo yed t his experiencebecause the job included trips tothe National Research Counciland was conveniently lo cated inKingston where his girlfriendattended Queen's,

He spent his next two terms at

This is a feature ofCoop th a t he found to be goodbecause it enabled him toconfirmhis interests without making anycommi tm e nts. As expected. his

interviewers for the next sessionalso thought it was a bit strange.His senior work terms were

spent with Electrohome in Kitc hener working on cable communications and the are ofsec uri ty for Pay T, V. Both simp lea nd complex scrambling and unscrambling systems were considered and "competitive" cheatin g systems were examined tofind ways to tighten any leaks inthe sy s tem. Daryl's reasons fornot enjoying Electrohome asmuch as he would have lik ed wasth a t th ey had too smallacommitment to R&D and they were toolarge a t the same time to h ave adynami c structure like that ofMitel.
