2Just Plain Craziness

As you read this the situation willbe several days old. However, itsrepercussions are bound to extendinto the future for quite some time.Our good friends, the Americans,shot down a commercial jetliner onSunday July 3, killing some 290people.

Now I m sure that this incidenthas drawn some comparisons witha certain similar incident in 1983involving a KAL jet and ournot-so-good friends, the Russians.Of course the circumstances are notthe same as the chairman of theU.S. Joint Chiefs of Staff, AdmiralWilliam Crowe, was quick to pointout. That s not the point. Thepeople on that Iranian jet are deadand they shouldn t be.Naturally this incidentdemonstrates something that isfundamentally wrong with theworld today. Everyone explainshow this shouldn t have happened;how unfortunate it is. But theproblem is that this kind of thingcan happen again. The Americansdidn t pull out of the gulf; theyhaven t changed their directives onaction to be taken againstunidentified aircraft.The worst thing is that from theinfonnation available, one almost

The conference, heldin the wake of the G7 Summit,didn t draw hordes of journalists,nor was the RCMP required.However, the issues t addressed,pollution, global warming, CFC sand the ozone layer, etc., seemed tome more important thanrestructuring the huge Braziliandebt.After reading the articles, I gazedaround my living room at the messof newspapers.

July 8 1988 Iron Warrior 3N E w sComputers ease essay writing

(UW NEWS) Computers arenow being used to help peopleimprove their writing skills. One ofthe software packages currentlyavailable is an AT&T BellLaboratories product called theWriter's Workbench. It wasdeveloped by the US NavalAcademy, and has been thoroughlytested by UW English professorsand studen ts.Writer's Workbench receivedrave reviews so we got it ,according to Dr. John North, a UWEnglish professor who teacheswriting classes. It was intendedfor people preparing documentationfor equipment manuals for the US

B est writing done yfirst year studentsNavy. What we found, though,was that every measure of goodwriting which the Writer'sWorkbench software made wasinverse to the actual value as evidentin examples wide ly accepted by theexperts as great writing.North asked Workbench to judgethe work of a number ofwell-known writers: GrahamGreene, Canada's MargaretLaurence, C.S. Lewis, andAlexandr Solzhenitsyn, amongothers. He also had Workbenchjudge writing samples obtainedfrom a number of people in UW'sEnglish department, including aprofessor, several graduate

students, and two first yearstudents.We submitted these toWorkbench, and it claimed that thebest writing was done by the firstyear students, and the worst was byC.S. Lewis and Solzhenitsyn , saidNorth. He added that most expertsrank Solzhenitsyn's work, even intranslation, as among the world'sbest writing.North stated that the abovefindings supported his own bias,which in turn was widely shared bymembers of the English department.Trying to teach students to writeusing existing computer softwarepackages is much like trying tolearn to play the piano by reading abook about it, or trying to learn tofigure skate by working solely onthe compulsory figures. Onemisses out on the feeling, the depth,the human expression that makestruly great writing worthwhile.However, North is quick to admitthat students who use the computerfor their essay-writing and otherassignments improve more rapidlythan those who don't. What thestudents tell us is that when theyuse the computer as a wordprocessor it becomes so easy tocorrect mistakes, move sentencesand whole paragraphs around, andso forth, writing becomes muchmore enjoyable, so they do more ofit. Students don't have to retypewhole pages .. they edit, re-edit,and re-edit again on the computerscreen. Because they do things somuch more quickly than is possible

AIDS A Guide for Parents(UW NEWS) Dr. John Orlando,a psychology professor at St.Jerome's College is co-author of anew book on AIDS called AIDS,A Guide for Parents . The bookcontains a wealth of information onthe subject and is designedspecifically to help parents whowould like to be able to discussAIDS sensitively and effectivelywith their children.Orlando wrote the book with Dr.Nettie R. Bartel, a professor ofspecial education at TempleUniversi ty in Philade lphia. Dr.

Roxanne L. Bartel, a medical doctorat Shattuck Hospital, Boston (arehabilitation hospital for AIDS anddrug p a ~ e n t s served as theirmedical consultant. They hadearlier collaborated to develop anew teaching program on AIDS forsenior public and high schoolteachers.We wrote the book because thereseems to be a high demand for itand there appears to be nothing onthe market specifically written for.parents, says Orlando, who is also

the former director of the Studies infamily Life and Human SexualityProgram at St. Jerome's. Our newbook... provides the latestinformation on AIDS and showsparents how to talk about thesubject to their children .. what tosay, when, and why. Althoughthere is no cure for AIDS it ispreventable through education.The book describes the disease,the manner in which it is diagnosed,and how it is spread. It alsodescribes its development, itssymptoms, and its mortalitypatterns. The book notes that therehas been so much sexual activityamong teenagers that a newawareness as to the risk of AIDS isurgently needed. There is also anurgent need for a re-evaluation ofattitudes, behaviour and values, inorder for people in this group toprotect themselves. The bookoffers advice on how parents maymost effectively Clchieve this. t ispublished by Jonet Publishing, 16DOrchard Mill, Kitchener, Ontario,N2P IT2, and retails at $9.95.

They find itmuch less so when errors merelyshow up on a computer screen.he computer permits each studentto learn at his or her own pace.North feels that the way to makecomputers even more effective is todevelop computer programs that aremore interactive. For example, the

computer could display a variety of

paragraphs which the student couldthen be asked to assess. In theprocess, the student would learnwhat makes a good paragraph, whattypical errors in composition are,how a thesis is developed, how tochoose an appropriate title, and soon. He is working on developingsuch a program.North's computer lab is located inHagey Hall, room 384, and is opento any student in the Arts faculty.

Their enjoyment of Canada andthe University of Waterloo,however will soon come to andend. Many people ask them whythey are going back.

Co-op in Japan ?By GregorySaumier-Finch3A ElectricalMany students, nowadays, havean affinity for tr dvel. As the modernage breaks forth with its high speedtransportation and globalcommunication systems, distancesgrow ever smaller. Daily worldevents afflict Ot:.:- conceptions ofother nations, and questions arise.What is it like to live in anothercountry? Where could I get the bestjob in my field, or, where are themost innovative concepts beingapplied? Our often misleadingmedia cannot answer all of these

questions. So what about fonningyou own conclusions? Completethe unfinished picture left danglingby incomplete attempts of portrayal.A void explanations tarnished byinfringing subjectivity, and launchyourself into an experience unlikeany other. Why don't you, theco-op student, go on aninternational work term?Planes, trains, and automobilesare there to take you away. Butbefore embarking, consider anappropriate destination. For a fewmoments put all else aside andconsider a work term in Japan.Japan is a country engulfed inmysticism and one that many maynot consider working in. AlthoughI am convinced that seeing foryourself is the only conclusivepath, to embark on the path toJapan, you must have someconvincing reasons.My experience with Japan isbased upon two events. The first iswhen I lived in Japan for eighteenmonths as a toddler and of which Iremember extraordinarily little. Thesecond was a ten day visit at theend of April 1988. Havingcompleted a work term in Taiwan, Itook the opportunity to visit Japanon my return journey to Canada.Japan, for a long time, has beenassociated with wonderfulmanagerial practices. The loyalJapanese does his daily calisthenics

in the factory playground, sings asong about peace and prosperity:and goes off to assemblemicro-chips. Hard work, sacrificeand co-operation are uniquetrademarks of Japanese society.The innovative technology that,combined with Japanese practice,turned Japan's economy into a 'booming success, is a trademark ofWestern creation. The future,however, looks very different.Why dont t you, theco-op student, go on aninternational workterm?Japan is today one of the world'seconomic leaders. "The Japanesemust play the game. They can nolo'nger reap the benefits withoutcontributing their share", shout theAmericans and echoed by theEuropean Economic Community.Japan has been attributed theresponsibilities of a superpower.Contributing to the global

advancement of technology is anexpensive investment. Japan is nowin a position to start contributingtheir share to research anddevelopment.

good ones before you rank your jobs.

Japan is setting forth a new imageof its future. Their transformationstarted in the late 1960's and early1970's with a shift from purelymanufacturing industry toknowledge based industry. Today,technological innovation is a criticaldriving force in Japan's economy.Japan's gross expenditure on R&Dis the third highest in the world.Billions of dollars are being spenton national R&D projects in areassuch as telecommunications, spacelaunch capabilities, fifth generationcomputers and software. Japan ispredicted to develop a quarter ofworld's new technology by the endof the century.Accessing Japan's technology isnot a simple task. Only recently arethe doors of Japan opening forWestern eyes. Canada's Scienceand Technology agreement signedin 1986 was a step in the rightdirection. With each newtechnology agreement, such as thatproposed by the U.S. at theeconomic trade summit in Toronto,the West gains more and betteraccess to technology. Access tolaboratories and high techinformation is becoming possible.Japanese researchers are combiningefforts with foreign researchers. Allvery well, but what opportunity ispresent in this environment for thestudent?

Canada and Japan made anagreement to establish a "WorkingHoliday Program". Under thisagreement any Canadian citizenbetween 18 and 25 years of age isauthorized to work in Japan. To seehow co-op students might beoffered employment in Japanesecompanies, I visited six largeelectronic based companies inTokyo. Meetings were held withmanagement from Hitachi CentralResearch Laboratory (HCRL), OKElectric, Toshiba, NECCorporation, Nippon Telegraphsand Telephone (NTT) andMitsubishi Electric.Reactions to the concept offoreign undergraduate employmentvaried. Co-op is defrnitely a foreignconcept in Japan. Employment for

July 8, 1988

four month periods is the exceptionrather than the nonn. In fact, mostemployment in Japan is life long.HCRL and OKI were the mostencouraging. Both HCRL and OKhave experience in hiring studentsfor four month periods, althoughmostly at the graduate level. All ofthe companies boasted of theircommitment to R&D and spoke ofextensive visiting researcherprograms with foreign countries atthe PhD level. OKI participates inorganizations such as IAESTE, andHCRL has its own program forforeign employment calledHIVIPS. Both want to encourageundergraduates. NTT was alsoencouraging but the remaining threewere still very traditional andconservative. The work would bemore like a training program, andyou probably w()Uld stay in thecompany donnitoriesLiving in Japan is a uniquelydifferent experience. The Japanese,descendants from China, areextremely unlike other Asians. Likethe transformations made toBuddhism, a religioas creation ofIndia, Japan today is in a uniquestate of modernism. Incensesniffing and Coke drinkingrepresent the extreme yetharmonious arrangement that hasbeen struck. The Japanese have notcopied Western ways but ratherhave adopted them. Baseball isperhaps the most popular sport inJapan. Although baseball is anAmerican game using Americanrules, it is played with Japaneseteam spirit or what is called "wa".Wa translates as "harmony". Theindividual glory of stardom andbarbaric outbursts of anger areforbidden. Like the way Japaneseplay baseball, they live in a countrywhose character is deeply rooted incultural tradition.

Japan will always be afundamentally differentsociety, a country ocontinuous discoveryJapan will always be afundamentally different society, acountry of continuous discovery forforeigners. The formidablelinguistic and cultural barriers areunlike any other country in theworld. Japan is technologicallysuperior to most other countries inthe world. Japan has the world'slargest market share inmicroelectronics and is coming outat the front of emerging technology.With the amount of business thatoccurs between Japan and othercountries of the West, it isdisturbing to think of theimbalance. The Japanese havepenetrated the West, yet the West isstill mystified by the Japanese.f Canada is to benefit frombusiness with Japan and technologydeveloped in Japan, Canadiansmust first learn about the Japanese,and set aside the barriers. Co-opstudents have the chance to do thisnow, so why not make it Japan?

The quotation, whichappeared in MUCESS (MelbourneUniversity Chemical EngineeringStudent Society) Magazine, is justone example of the manysimilarities that exist betweenengineering here and that found halfway around the world. Many ofthese similarities can be attributed tothe common origin of ourengineering (i.e. England), butothers stem from that certainpersonality that engineering seemsto attract.

As far as courses go, in thetraditional engineering departments,the Australian ones are almostidentical to ours in terms of content.The course load is similar andschool is for eight months (fromMarch to November).

by Todd RuthmanIB Systems DesignThe human brain has long beenheralded as the greatest computeron Earth. Researchers have takenthis analogy to heart and havebegun theorizing, simulating andeven building computers modeledafter our own biologicalprocessors. The theory is calledneural networking, the hardware -neural computers.Like the brain, a neural network

consists of a large number ofindividual processors, each oneconnected to many others throughinput and output routes. It is thisinterconnection that gives a neuralnetwork its power. Another namefor neural networking isconnectionism.

consists of a largenumber of individualprocessorsDifferent biological processorscan react to their inputs in differentways. The connections betweenthe processors vary as well. Eachneuron (processor) has a thresholdvalue and an output value. Eachconnection (synapse) has a weight.The weight of the connection actsas a multiplier for the processor'soutput signal. It can increase ordecrease the value of the output, or

i t can change its sign (+/-).Positive inputs are called"activations" while negative valuesare know as "inhibitions".f the sum of a neuron's inputsexceeds the threshold level of thatneuron then it 'fires'. This 'firing'sends that neuron's output value toall other neuron's that are connectedto it through its output paths.Along the way, the output signal ismodified by the weighting of theconnections.For hardware implementation,variable resistors can be used to

weight the connecting wires bycontrolling the current flow alongthe wires. The weights can bepermanently set or variable.Networks with variable weightingcan the capacity to learn.There are several exci tingimplications of neural networks.Because data storage is spread outamong numerous processors,memories can be recalled evenwhen some of the processors fail.This allows for a slow degradationof performance rather than a drasticsudden failure.

Brain in a BoxDue to a neural network's methodof data analysis, it may be able tomake a match for something itdoesn't have stored in its memory.

While D is different from D, anetwork might still, knowing one,e capable of recognizing the othersince there is much in commonbetween the two.Instead of strict classificationrules, a neural network usesimplici t natural rules in relatingstored data. It can also modifythese rules to deal with new data,such as the previous example of thesame character in a different fontOther abilities of neural networksinclude the capability to matchdegraded images to those it knows,to link items together and to linkitems with various categories.

Thenetwork uses the score to adjust itsweighting structure and tries againuntil an acceptable score isachieved.Once the network achieves anacceptable level of success, theweighting structure can either be'frozen' in place or be left tocontinually modify itself so that theneural network keeps learning andadapting.It would seem, perhaps, thatneural networks are the answer tomany processing problems but itmust be remembered that most ofthe work is still many in theresearch and prototype developmentstages.

network soon that evaluates loanapplications. Another neuralnetwork called, NestorWriter, canrecognize 2500 commonly usedhandwritten Japanese characterswith about 90 accuracy, and a;fast as they are written.It should be noted that neuralnetworks are not generally beingdeveloped to replace standardcomputers. Most of the presentresearch stems from the concept ofthe network as an interpreter of rawdata (pattern recognition). Theinterpretation would then be passedto a conventional computer to beprocessed.

Caution must be exercised inexpecting too much too soon fromneural networks. Most availabletoday are small and can onlyperform simple tasks in a labe n v i r ~ f l m ~ n t . But ~ i t h the steadilygroWIng Interest In the field, wemay not ~ v e to wait much longerto see therr common application.ecause of these abilities, neuralnetworks lend themselves best toprocessing raw data. The specificarea to which they are being appliedin current research is patternrecognition. Neural networksshow great promise in therecognition of the hardwritten text,speech recognition, and even

identifying vehicles using radartraces. The reason the neuralnetworks can excel in these areas isbecause of the way they can beprogrammed. Instead of followinga rigid set of algorithmically codedroutines, the network can learn.This is due to the variability inweighting of the connectionsdiscussed earlier. Networks applyle rning rules in their operation.

Instead of ollowing arigid set of codedroutines the networkcan learnIn 1949, neurophysiologist

~ o n l d Hebb proposed thatSImultaneous activity in biologicalneurons makes the connectingsynapse stronger. Atrophy willoccur if there is inactivity betweentwo neurons. This rule is appliedto most learning techniquesimplying that the networkreinforces re-occurring input signalpatterns.

Once a network with variableweighting is constructed (there areseveral ways this can be done: pureparallel hardware, partially parallelhardware and software simulation,or pure software simulation onconventional serial hardware), it isthen usually trained usingsupe.rvised training or gradedtraInmg.In supervised training, thenetwork is given both inpu t and thedesired (correct) output. It thenruns .through some trials,companng its results to the desiredoutput and correcting for errors.

by Marc Gerin4A CivilOn July 1st the campus camealive with thousands of visitorsform the Kitchener Waterloo area.They were attracted by the large

number of events making up theK-W Canada Day celebration. Theday started with a parade featuringour beloved RIDGID TOOL ridingin an open air convertible,accompanied by the EngineeringHard Hat Band.

The afternoon events kicked offwith opening ceremonies where 20000 balloons were released andskydivers braved the high winds toland, on target, amid the crowd.The group Endless Summer kepteveryone hopping and bopping allafternoon to the music of the BeachBoys. Meanwhile, kids could have

their face painted by Recreationstudents, discover the campusthrough MathSoc's scavenger huntor compete in the kite flyingcompetition. Entertai nment in theCampus Centre, SciSoc's dunktank and roaming clowns all addedto the carnival atmosphere.In the evening, the activitiesmoved to Columbia fields whereEngineering ran children's games.CHYM radio was there withvarious competitions, such asJell-a' stacking and Life Saverlaunching, while the KiwanisKavaliers' marching band kepteveryone entertained until thefireworks. The largest display inK-W, the fireworks lit up the skyover Columbia lake in a dazzlingarray of COIOUTS. A perfect ending, to a great celebration.

300 Kids ?by Marc Gerin4A Civil

Kathy Wood3A ChemicalEngineers and kids, a perfect mixjudging by 'the success of thechildren's games at the Canada Daycelebration . On July 1st,engineering students looked after

three hundred kids at once for aperiod of four hours. An amazingfeat of endurance According toparents' comments, it went great.The only complaint was from a ladywho said her kid didn't want to goeat dinner in fear of missing someof the fun. It appeared thevolunteers enjoyed the games asmuch as the kids and didn't want tomiss any of the fun either.Congratulations are definitely inorder for the more than eighty

volunteers who made this majorevent happen without a singleproblem. As organizers, we weretruly amazed at the level oforganization present on a field withhundreds of kids, half of theirparents and a dozen games goingon at once. Everyone just wentahead and did what they had to doand did it very well. Wheneverthere was extra work to be done,there was always somebody willingto help out. This included cookingfood in the afternoon to gettingmore tables for the ga mes to trafficcontrol after the fireworks. Thiswas certainly an important factor inmaking the children's games run sosmoothly and n making the CanadaDay celebration a real success.The day came to an appropriateconclusion with the Fed Hall crowdjoining in with the engineeringvolunteers to sing 0 Canada.

It is often difficult to sortthrough the collage ofmulticoloured 8 x11.5 postersplaced at random throughout ourhallowed halls. Such advenis ingwhile being time consuming andexpensive, is usually ineffective.The centralized information centerwould offer a cheaper and moreeffective way to promote oncampus events. It would soon beestablished as THE PLACE whereone can go to get a completeaccount of the week's events (clubmeetings, seminars, presentations,etc). It would be a controlledaccess environment and would helpto alleviate the problem ofout-of-date and undesirable posterscluttering the halls. Theinformation center would also serveas a publication distribution cente rfor Engineering newsletter, IronWarrior, Project Magazine, etc.

CLUBS/SOCIETIES HOURMurphys' Law #42: The

number of students at a clubmeeting, seminar, or eventscheduled during class hours isinversely proportional to attendanceat the "DIFFY Q ~ S tutorial.I t has become nearlyimpossible to schedule interesting

technical seminars, club meetings,or guest speakers without excludinga large number of students whocannot participate due to conflictswith their schedule. In order toexpand accessibility to andawareness of on campus clubs andsocieties, Eng. Socs A and B planto put forward a proposal to theengineering faculty for theestablishment of a clubs andsocieties hour common to allundergraduate engineeringschedules (the same concept as theexisting class professor hour everyTuesday at 11 :30). Preliminaryinvestigation has shown theThursday from 11:30 a.m.- 12:30p.m. time .slot to be the mostfeasible. Some departments alreadyschedule this time slot for seminarsand department presentations. Thisproposal in no way suggests thedeletion of the class professor houron Tuesday'S.

July 8, 1988

by Jorge SerradorIB Systems DesignStanding in the middle of a plain

of ash grey mud under a sky ftlledwith green stars stood a burned outbuilding. Smoke or what thehumans called globs rose from thebuilding. It stood for globulessince the atmosphere of this planetcaused the smoke from burningobjects to rise in drops like a taprunning against gravity. Movingtoward the remains of the structurewas a group of metallic lookingbeings carrying coal black rifles anddust grey knapsacks. One raisedhis hand and the rest stopped.We'll take a break at this rubble.Steverktyou take first guard duty.said Lieutenant Fullton into his

comm mike. He looked at hisHUn for any signs of trouble ormovement in the kilometres aroundhim and being satisfied there wasnone, turned it off. He hatedhaving to live in his enviro suit. Itwasn't that it was thatuncomfortable but not being able totouch anything with his hands madehim feel so sterile. He wished hecould have been assigned to aplanet with an atmosphere thatwasn't deadly to human life. Well,he had better get some sleep beforethe dawn patrol.

Hi Avrum, how's it going?said Tom Fullton walking down themetallic corridors toward a tall thinman wi th dark curly hair andglasses. Avrum smilled at thebrown haired, 5' 9 , stocky figuregreeting him.Not bad Tom, how are thingswith you? Avrum replied stopping

to talk awhile.Well I'm getting behind inthermal and tectonics but I figureI'll catch up this weekend. What'dyou think of that atmospheremidterm? questioned Tom.There are some thingsmore important than thisinstitute. People aredying out thereThe midterm wasn' t too bad but'I was hoping to talk to you. Tomgrunted for him to continue. Wellyou see I 'm going to ademonstration that the UniversalPeace Alliance is putting on and Iwas wondering if you wereinterested in coming. We're tryingto end the war with , .e Mattaloids.What do you say? Avrumquestioned anxiously.I really wish I could but youknow I'm behind in most of mycourses and finals are coming.

Iron Warnor

Twin Stars RisingOkay, see you later. Avrumsaid promptly and left. Tom hadnever seem him just leave like that.Of course he could understand howhe had strong feelings on this. The

war with the Mattaloids was just afew months old and there was agreat debate because no attempt hadbeen made to contact or talk withthis alien race. And just last weekmartial law had been instituted andan official declaration of war hadbeen made. Well, I don't have thetime to get involved, thought Tom,so he headed back to his room andwatched TV.

Wake up lieutenant, it's time tomove out. corporal Jellegma saidshaking Tom. Tom wokeremembering his dream of A vrum.Suddenly it all came back. Afterthat he had not seen A vrum forseveral days. Tom Had gonelooking for him only to find out hewas at the departure dock. Tom ranto the departure docks to findA vrum about to leave.What happened? Tom hadasked frantically.I was arrested for demonstrating

against the war with the Mattaloids.aAct. They have decided to expellme from the Interplanetary Instituteand send me back to my horneplanet. Avrum had replied calmly.

Why did you do it? Tom hadpleaded. What about your future?What are you going to do now?

Avrum had looked quietly at Tomand responded, There are somethings that are more important thanthis institute. People are dying outthere for a war that shouldn't behappening. Tom, you are a smartguy, don't you understand thatsomeone has to speak up.

But why you? Other people arespeaking up. They can stop thewar.Torn that's what everybodythinks and with thinking like thatnothing gets done. The departurebuzzer rang for the people to boardand Avrum looked at Tom for onelast time. He smiled and saidWe've got to keep protesting.This is too important to ignore.Good luck.

And with that Avrum had turnedand boarded the shuttle. Tom hadbeen in a state of shock. A vrumhad been one of four students fromhis planet to be accepted to theInterplanetary Institute. Now hehad been kicked out over somestupid war. Tom had never doneanything after, deciding not to riskhis future over some conflict lightyears away. Someone else wouldtake care of it. He remembered he

had been unable to understand whyA vrum did it until the day he hadbeen drafted.So here he was staring at the pre

da wn ash sky of some godforesaken planet where theMattaloids had been found. Heswitched on his HUn unit andlooked around. Everything eemedto be fine and the men werepreparing to move out. His mindwas still drifting to images of theInterplanetary Institute where he

had been an undergraduate. Avrumhad been his best friend and theyhad done everything until thisstupid war had come along. ThenAvrum had gotten involved with thepeace activists. Tom had alwaysbelieved that it was none of hisbusiness and he didn't have thetime to get involved anyway. So hehe had occupied himsel f with otherpass times (mainly TV).

He remembered thinking, whatwould one more person do for thecause? They didn't need himanyway. And so here he was.How often he had wondered whatwould have happened if he had gotinvolved . Would he be on thiswretched planet leading a group ofmen out to kill some aliens he hadnever even communicated with?

Tom had alwaysbelieved that it wasnone o his businessand he didn t have thetime to get involvedSuddenly his comm unit activatedand the voice of his Captain cameover the air. Action to the north hewas told. He responded andinformed the Captain that he wasproceeding towards the reportedarea to verify. His comm unitswitched off and Tom told the mento form up. They were moving

out.Again the metallic men moved outpast the rubble that was still givingoff the pink globs. Tom looked atthe smeared landscape surroundinghim. Dotted about were strikingpurple things which he had neverbeen able to describe. They lookedlike some kind of fluid separatedinto thousands of tiny little dropletsand then stuck together to fonn agiant upside down mushroom.

This was one of the indigenous lifeforms on the planet. He could notbegin to recount all of the sites hehad seen while fighting this war.The worst had been the Mattaloids.They were creatures which lookedlike a lion which had been skinnedalive. They were a bright redcolour covered in a blood-like oozewith huge fang-like structuresprotruding from their front. Theyalso fed on the dead humans leftafter a battle.Most humans got sick the firsttime they saw them but Tom hadalready been through that. He hadseen quite a few dead and had killeda few himself. He had killed. Atthe Interplanetary Institute Avrumand Tom had once discussed killing

and both had agreed that they couldnever kill another intelligent being.Tom had proven himself wrong.He had killed. He hated this warand everything it stood for. Howhe wished he hadn't been drafted.

His HUn lit up warning of actionin the area ahead. His men took upa skirmish formation and theweapons were prepared. Tom toldhis men to proceed with caution asthey moved in. Tom was trying toconcentrate on the HUD but he keptremembering Avrum and his daysat the Interplanetary Institute. WellA v r u ~ he t ~ o u g h t all y o ~ rwar.

Fuck, the whole peace movementwas useless. It would have donenothing anyway, Torn dccid d andconcentral 'd more intently n hi:IIUD .The a ;tion was gelling very closenow and Tom cautioned his troopsagain. He was watching his HUDcarefully. Something was fishy.They hadn 't been hit yet That wasunlike the Mattaloids and Tom wasgetting nervous.

Then he knew what wasgoing to happen. Hit the dirt, heyelled over his cornm unit as a shellhit right in the middle of the platton.Shrapnel flew everywhere and Tomscreamed as a piece ripped throughhis suit.His HUD display flashed brightred warning the suit had beenbreached and then disappeared asTom's damaged battery no longerprovided adequate current. Tomfell to the ground knowing that itwouldn't be long before he was

dead. His mind went back toAvrum. If he had only gone withhim that day maybe everythingwould have been different. If hehad only listented to Avrum.Tom gazed thinly upon the twinstars breaking above the ash greyhorizon to reveal a brilliant greensky, thinking only of what mighthave happened if he had it to do anover again.
