The practical importance of Einstein's formula was no t , reali7.ed until approximately 1939 when experiments showed tha t matter could,under certain circumstances, bechanged into energy and vice versa.Two German physicists split a ura

Engineers?

odel itizens

by Greg Dee

So, Mr. Angry likes to think tha tengineers are "bad-assed dudes." Iguess everybody's entit led to theirown l i t t le fan tasies - especially considering the pressures Mr. A ngry isfacing as h e strives to excel in one ofthe most demanding academic p rograms of our university.

Le t 's face it. M r. Angry, like mostfourth year engineers, is a model citizen . Mr. Angry ha s jus t 8 monthsmore of preparation before he entersone of society 's most well-r espectedprof essions . He'll most. likely begin his job with a starting salary o faround 30K , settle down and buy ahandsome bungalow so m ewhere andeven get married La the fin e youngwoman in Dance that he meL bere atWaterloo . Mr. Angry w ill be ma.king a positive and much-valued co ntribution to society. When someonein our society applies for th e ir Canadian passport and they need someone to vouch for their identity it isn 'tpark vagrants, drug dealers or serialkillers who are allowed La sign, i t 'sprofessional enginee r s, lawyer s, doctors and members of the clergy .

Society needs engineers. Engi-neers will play a key role in sol v ngthe techno logic al problems posed byair pollution, dwindling natural resources and over-population whic hmust be solved if mankind is to survive. It was engineers who createdthe industrial revolution, who builtt,hp. ClIlt,nmnhi1f' '. whn rlpsip-npri l .hptelephone networks , who inventedthe medical equipment and whobuilt the hi ghw ays, hospitals andschoo ls that have all co n t ribu ted toan increase in the prosper it y and

we lfare of the general population . Aprosperity and welfare tha t has fueled social progress in a ll area s ofsociety such as universal medicare,worker 's rights, woman 's r ighLs andold age pensions. Most engineersr ecogn ize the importance of their

role in the history of society andtechnology, and more importantlythey recognize their responsibility tothe future of society.

It is in fact engineers who areour own strongest critics as the"point" section of this article soclearly shows. Engineering is a selfregulated profession governed in Ontario by the A.P .E .O. Every once ina while when the engineering students a t Waterloo get a l i t t le biL outof hand it 's the A.P.E.O., engineering faculty members and our own

elected engineering socieLy who havetradit ionall y exerted th e most influence in keeping us in lin e. It hasnot been the whiny fringe interestgroups or fru strated fem i nists .

Wh e n you compar e e ngine e ringstudents to students in other faculties (something arts st ud e nt s andwriters for a ce r tain othe r newspaper on campus hav e done incessantlysince T arrived on campus four yearsago) there is no doubt tha t we workharder . We needed higher marks toget in and we wi II be .of greater val ueto soc iety when we graduate . I agreecomp letely tha t so c iety needs lotsof sensitive young people who really appreciate poetry but they needpeople trained to produce shelter,t.r

SPACENEWSEditor s CO/linIn

Welcome to the first issue ofSPACENEWS, a bimonthly reporton space news and technology. Thisnewsletter is written by Universitystudents from across Canada and ispublished In several studentnewspapers.

My motivation for the newsletterarose several months ago when Iattended a Symposium organizedby the medical school at theUniversity of Ottawa. Students fromacross Canada attended seminarson various topics in medicine. Theextremely successful symposium

achieved several objectives.1. It allowed students to learn

about state of the tlrt researchin medicine.

2. It provided students anopportunity to meet otherstudents from differentuniversities.

3. Provided students with manyathletic intramural activities,and allowed time to visit thecity.

4. Provided a dinner and dance atthe end which was superb.

U.S.A.The space shuttle Discovery s 3main engines successfullypassed the Flight ReadinessFiring on August 10. Launchdate is scheduled forSeptember 29, 1988.NASA is asking U.S. schoolchildren to select a name forthe replacement space shuttle.The winning entry will beannounced next May .President Reagan announcedthat the winning entry for thename of the space station isFreedom.The "Mars Project" society ofscientists revealed that in 1976NASA's Viking spacecraftdiscovered a massive rock onthe surface of Mars in theshape of a human face.Former astronaut BrianO'Leary, an expert on Mars hasapproached the U.S.S.R. inhopes of having the areaexamined by the first of twoSoviet probes bound for Marsthis year.

90 international scientistsgathered at the University ofNew Hampshire to plan the1992 'International Space Year'which is to coincide with theSOOth anniversary ofChristopher Columbus' voyageto the New World

U.S.S.R.

Two cosmonauts successfullyreturned to earth from a weeklong mission to the Sovietspace station MTR afler twoaborted re -entry attempts dueto failing stabilizing rockets.The re -entry capsule wasreported to oniy have 48 hoursof oxygen. A third cosmonautremained on MIR to monitorthe health of two cosmonautsthat have been in space for 8months.Frenchman Jean Loup Chretienwill be on a month longmission to MTR in November.He is scheduled to become thefirst non-Soviet, non -Americanto take part in a space walk.Internationf' 1 space artistsgathered in Iceland to sketchthe volcf' nic surfac e which issimilar to that of Mars. Thesketches will be shown inMoscow next April whenPhobos 1 and Phobos 2, theexrl orat ion satellites If' unchedin July, arrive to orbit theMartian moon Phobos.

Costa Rica

Costa Rican shuttlenautFranklin Chang Diaz isproposing a Pan-AmericanSpace Organization (PASO) topromote cooperation betweenlatin /\merican countries,particularly in satellite tracking,

It seemed to me that there are fewsimilar opportunities for Canadianengineering students of al ldisciplines to meet and 'earn in aprofessional environment. The ideaof starting an engineeringsymposium was tempting formonths, but it requires the supportof many students. As an avid spaceenthusiast, it suddenly dawned onme that a space newslett(>r wouldbe an ideal way for students acrossCanada to communicate. Space isa topic that interests most youngengineers, and the space industryemploys engineers from alldisciplines.

I hope you enjoy this first i sue ofSPACENEWS. I encour, and yourUniversity. Perhaps some < lay wewill all meet for a 'S paceSymposium' at some Canadianuniversity over a weekend

The National Aeronautics andSpace Administration (NASA) isinstalling a 10 -foot telescoping polein each space -s huttle orbiter to helpthe crew bail out in an emergencythat might prevent the orbiter fromlanding safely. The pole will guideeach astronaut jumping frommid-deck to pass below theorbi ter's left wing. Without thepole, an escaping astronaut wouldlikely hit the wing or some part ofthe orbiter.

The pole is part of an escapesystem that is standard equipmentfor all future shuttle flights,including that of Discovery,scheduled for launch on September29,1988. The complete systemallows the crew to jettison the

hatch side of the orbiter, andincludes a helmeted pressure suitand survival equipment that eachcrew member must wear duringlaunch and landing.

Rogers Commission Urging

The entire system, which costssome $75 million to develop andinstall in the three present orbitercraft, was devised in response to arecommendation by the PresidentialCommission on the Space ShuttleChallenger Accident (the RogersCommission).

The commission urged N"SA to"make all efforts to provide a crewescape system for use duringcontrolled gliding flight". Sinceejection seats were removed fromthe first orbiter, the Columbia, afterthe shuttle's initial four test flights,there has been no way out for thecrew in an emergency.

According to Robert Rice, NASA'screw escape project manager, theescape system can be used only in acontrolled flight below 20 000 feet -either when the orbiter is coming into land at the end of a mission, orwhen a launch has been aborted.

Rice said however that the systemwill not work within the first twominutes after lift-off, when the solidrocket boosters are stil1 firing - aswas the case in the Challengerdisaster. Nor can it be used if the

orbiter is descending out of control.

Emergence Rescue

In an emergency where the crewcan get the orbiter into a controlledglide above 25 000 feet, they wouldset the autopilot to make thevehicle descend at the minimum airspeed of 175 knots (325 krn/h) -about two thirds the vehicle'snormal speed at that altitude. At 25000 feet, the crew would vent thecabin to bring about ambientpressure, and at 20 000 feet activateexplosive bolts to blow the cabinhatch cover away from the orbiter,

A pull on the telescoping pole'strigger would shoot thespring-loaded pole from its housing

on the mid-deck ceiling out of theopen hatch and lock it into itsextended position within a second.Each crew member would in turnhook his or hC?r parachute harnessonto a ring shaped attachment onthe pole, kneel in the hatch, androll forward through the opening.

The procedure would allow an entirecrew of eight to evacuate the orbiterin ahout 1-1/2 minutes, well beforethe orbiter reached the minimumbail-out altitude of 5000 feet.

The purpose of philosophy is / 0discover t.he most. fundamental aspects of reality. It includes, for ex

ample, metaphysics , which is t.he science of being as being; epist.emology, which is the science of knowledge; and et.hics, which enahles l iS t.odist.inguish right. from wrong. Sometake the view t.hat. it. is impossible t.odiscover ul t imate trut.h and t.he at.tempt to do so can lead one int.o anint.ellectual vacuum. A view, qllitepopular today, is tha t t.here is no objective t.rut.h but if yOll believe so m et.hing, it is t rue for YOll and t.hat. isas far as it. goes.

There is , however , a monolit.hictru th independent. of or i n ion andfurt.hermorc it. is wit.hin t.lte powerof the human int.ellect. t.o discover

some fundament.al aspects of it.. Afull validation of t.his will not. be at.tempted here, for it. is an ext.remelycomplex problem which goes far beyond the scope of t.his art.icle. Someapproaches will, however, be suggest.ed.

What. are the ult.imat.e constit. uents of realit.y and from what.can we begin a search for t.ruth?

Nuclear physicists say tha t we willknow the ultimate constituent.s ofrealit.y when the ult.imat e particle isdiscovered and t.he four fundament.alforces of nature are unified. Muchof today s science is essent.ially n -dllctwnis/ . It. at tempts t.o achievei hrf I.N lIndNqf ;)nriing of I hings byreducing f,IH 11l to 11t{'lr ll10St. basiccomponents .

This, howcver, is a nec(' ss a ry but .not a sufficient. means of invest.igat.ing realit.y. This is because physica l being has two aspects - a II/atl -I Ia/ and a formal aspect. . To illu st.rat.e this we can conduct . a thoughtexperiment ill which we analyze theessence of an automobile .

Philosophical TruthOne can im agine t.wo situat.ions .

In the first , t.here is afl assembledaut.omobi le with its full complementof parts. In t.h(' second, the filiicomp le m ent. of parts iR presenl butlying in a disassembled heap onthe gr o un d . Now, if the essenceof the aut.omobile werc s imply reducible t.o it.s par ts we could ca llthe disassembled heap an aut.omobile, which is absurd. Somethingin ad d ition to the par ts of a material bring is needed to give it it s bein g . Th i s addit.ional prillcipl e is theform . li'orm is t.he arrangement orinter-connccl.ivity of the parts, while/ltIllh.,. is t.he part. s themselves . Bothprinciple s of malLer and form are required t.o compose a material being.Reductionist science gives us an U -derst.anding of t.he material side ofreality and negle c t s t.he formal.

One means of obtaining a bet.

ter grasp of the t.rue in philosophyis to understand t.he false. Onemeans o f discerning any philosophically false position is to know tha twhen a certain t ru th is denied , tha tt.ruth is implicitly used in the denial. Many philosophers have contradicted themselves in t.his manner. For examp le, some philosophershave stated tha t we cannot knowtha t what. our senses reveal to usis correct because we do not knowhow milch th ' rnrS "::tr'('t: h:)"" h/>"11distort.ed by the S l l t ' l ' ~a l l u 1 1 - ' r \ ' ( ) U ~systelll. The falla cy of t hi s argument is tha t it implies t.hat . we canknow some aspect of objective real

it.y (namely the senses and the nervous system) to d eny h a t W ( canknow any objective reality. ,.

If we look at , t.he denial, tha t thehuman intellect ca nnol. know truthwe call underst.and the st.at.emcnt. tobe false because it. present.s itself asa t.rut.h . 1 the person lIIaking thedenial applies t.he principle of skepticism to the denial itself and stat.est.hat we ca nnot. even bc slIre of that.,two observations can b(' made. Thefirst observat.ion is tha t he may beonly st.ating hi s personal inability 1.0arrive a t t ru th and not. necessarilyt.hat the human int.c1lert cannol., 1'0'8 ; , arrive a t trut.h. The second ohservation is tha t he is refuting him-

se lf by inconsistency. f he ap p li esa principle of absolute skept. icism t.ohis denial he repudiat.es it becauset.he degree that. olle is uncert.aill o fa position is the degree tha t 011e depar ts from i t . From this we ca n s ta tethe first law of epistemology: t.hatt ru th exists and the human int.ellectcan know some fundamental aspect.of it. . This principle is Itot. arrivedat through deductive reasoning hut ,carnes the evidence of it se lf withinit.self.

Truth exists lind the human

intellect can know some

Jundllmentill upect o j it.

The search for philosophical t.ruthbrings us t.o the summit of nat.ural

knowledge which is mcirrl'h . lsir s .It is the science of being qua being,which is achieved through a maxim u m degree of abstraction. t is atthe summit for two reasons. First,it is the governor of all t.he otherscie nces , for t.hey must borrow fromt h e principles of metaphysics to opf'riltf'. Sf conrl. it is pf rferl lv frpc ,which means t.hat it. borrows principles from no other science. Jt.s princi p le s are most certain a n (\. evident.within themselves.

The u l t imate first principle is thelaw of id t :l l i ly which st ,at.es t.hat.
