“This will be a very important resource for beginning scientists so they can see what thefield is like, especially this all important topic of how to build prestige and a track recordfor excellence.”
—John D 'Angelo, Alfred University, New York
Describing the philosophy of the scientific method and the training and professional characteristicsneeded for a successful career, Scientific Research as a Career is a comprehensive “how-to”guide for the aspiring scientist. Based on the author’s experience both as a scientist in a researchorganization and as a university mentor, the book covers:
• The interaction between management and leadership principles and scientific research
• Qualifications and attributes usually required to become a successful researcher
• History, application, and prerequisites of the scientific method and scientific progress
• Exploration of the careers of pivotal and influential scientists
The author highlights the importance of networking and the value of forming contacts withcolleagues, joining scientific associations, attending conferences, making presentations, andacting as chairs for conference sessions. He also touches on the many areas outside of “thescience” that readers are likely to encounter during their career, such as mentoring, supervisingresearch students, and managing a group. The book clearly delineates not only the challengescurrently facing scientists, but also how to overcome them and achieve success in their careers.

Motivation and Requisites for a Research Career
Manywhoembarkonacareerinscientificresearcharemotivatedbyacuriosityabouttheworldandadesiretotackleandsolveproblems.Thisisonethingthatcomesthroughclearlywhenresearchscientistsareinterviewed.InaU.S.PBS(PublicBroadcastingStation)televisionprogram,Cool Careers in Science(ScientificAmericanFrontiers),dis-cerningquestionswereposedtoanumberofnotablescientistsandengineers.Thetextcanbeaccessedonlineandshouldmakevaluablereadingforthosecontemplatingaresearchcareer.*Theseresearch-erswereaskedquestionsthatincludedwhytheydecidedtobecomeresearchscientists,whatacademicbackgroundisneeded,whattheydoduringa typicalworkday,what they likemostabout thework,andiftherewasanythingtheydonotlike.Therewasacertaincon-sistencyintheanswers,asmaybeexpected,andsomeofthepointsmadebytheintervieweeswillbediscussedthroughoutthisbook.There are many requisites for researchers, but I believe that therearethreethatareessentialifascientististohaveasuccessfulcareer.

The fear is that scientistswill become toospecializediftheyconcentrateononenarrowarea.However,fromthepointofviewofresearch,whatisrequiredisdepth,notbreadth,of knowledge.

It isillogicaltothinkthatsomeonecanadvancenewknowledgewithouthavingacquiredalevelofknowledgesimilartowhathasalreadybeenachievedinaparticulardiscipline.AlbertEinsteinreachedapointwherehehadtomastersomemathematicalprinciplesbeforehe could progresswithhiswork.This canhappen inotherareasof creative work,notonly science.Beethoven struggled tomastercounterpoint before he could use it in his music.

Research Ph.D. versus Combined Research and Course Work
In the transition from the bachelor’s degree to the postgraduatemaster’s and doctoral degrees, there is a fundamental divergenceof the requirements in different countries. In somecountries, suchasAustralia,NewZealand,theUnitedKingdom,andGermany,thePh.D.isapureresearchdegree.Thismeansthatthestudentpursuesaresearchproblemforseveralyears,culminatinginathesis.Thethesisis then sent out for examination by at least three experts of inter-nationalstandinginthefieldoftheresearch.Theoutcomeisdecidedby a panel from the student’s university based on the examiners’recommendations.Thestudentmayfail,beaskedtocarryoutaddi-tionalexperimentsandresubmit,revisecertainsectionsofthethesis,orsimplymakeeditorialcorrections.Thelasttworequirementsmayberelegatedtothestudent’ssupervisor toensuretheyarefulfilledbeforethedegreeisawarded.Thistypeofdoctoraldegreerequiresnocourseworkandthereforenowrittenororalexamination.

Fromtheperspectiveof training tobecomearesearchscientist,I considerthepureresearchdegreewithoutcourseworktobesupe-rior.Beginningattheageoffive,throughprimary,secondary,andtertiaryeducation,studentsareaskedtositinclassroomsandarefedinformation.Ithasbeensaidthatchildrenarealwaysgoingaroundasking questions but that society has an effective way of deal-ingwiththisproblem.Itiscallededucation!Bytheendofthefirst(bachelor’s) degree, a student should have acquired a sound basicknowledgeofatleastonescientificdiscipline.Furtherforce-feedingof information together with tedious assignments may only serveto erode the spirit of inquiry that is essential for research. Whengraduatestudentsbegintopursuearesearchproblem,itis impor-tantthattheybegivenacertainamountoffreedomtoconcentrateontheproblem.Thisentailsexperimentalworkwithsimultaneousself-studyand focused thinking.Theadvantageof this is that thebooksandarticleschosenforreadingwillberelevanttotheresearch,andthestudywillbemoreefficient.Muchofthecompulsorycoursework,ontheotherhand,maynotbeusefulandmaytendtoinstillmind-sets.Furthermore,withoutcoursework,thestudentwillmorereadilydevelopacriticalattitudetotheliterature.Whatisreadcanbecomparedwithwhatisfoundbyexperiment.It is importanttodistinguish between acquiring information and acquiring knowl-edge. Information is received and stored passively. Knowledge, inaddition, requires an active input from the individual. When theinformationiscriticallyevaluatedandconsideredtobesound,thenthisbecomesknowledge.Whenalotofinformationisdispersedincoursework,thereisagreatertendencytoacceptwhatistaught,andmindsmaybecomelesscritical.Theremaybeagreatertendencytoacceptandnottochallenge.Thiscanresultinregimentedthinkingratherthantheimaginativethinkingneededinscience.

Imaginative and Regimented Thinking

Anotheraspect to comparebetweenapure research degreeandoneinvolvingcourseworkisthequalityoftheresearchcontent.Ifthetwotypesofdegreesrequireaboutthesametime,threetofouryears,thenlogicallythestudentwhoisfreeoftheburdenofcourseworkwillhavemoretimetodevotetoresearch.Goodresearchneedstimeforthinkingtomature,forcriticalexperimentstobedesignedandcarriedout,andforsoundconclusionstobereached.Ihavehearditsaidthatgraduate students should bemade to come into the laboratoryandwork inbetweenclasses.Mostresearch,however, requirescontinu-ity.Someexperimentstakelongtimes,orthetimeforanexperimentcannot always be predicted. It is important to distinguish betweengenuine research and the collecting of data to put into figuresandtables.Muchofwhatgoesunderthenameof“research”thesedaysissimplythelatter,andthatcancertainlybedoneinbetweenclasses.

WorldWarI.Hewaschallengedbytheproblemofwhatconstitutesthescientificmethodor,morespecifically,whatisthecriterionthatdistinguishesascientifictheoryfromnonscienceorpseudoscience.At the time, several theories were being widely discussed. Theseincluded the theory of Adler on “individual psychology,” Freud’spsychoanalysis, Marx’s theory of history, and Einstein’s relativity.WhatstruckPopperaboutthepsychologicaltheoriesofAdlerandFreudwastheirapparentexplanatorypower.Thereseemedtobenoinstancesofbehaviorthatcouldnotbeexplainedbythesetheories.Everyeventcouldberationalizedasa“verification.”ThisledPoppertosuspectthatthisapparentcapacitytoexplaineverything,ratherthan being a strength, as their adherents claimed, could be theirweakness.InthecaseofEinstein’stheory,itwasquitedifferent.
Oneof thepredictionsof the theoryofrelativitywasthat lightshouldbesubjectedtogravitation.Totestthisprediction,expedi-tionsweresentoutin1919tomeasuretheapparentpositionsofdis-tantstarswhentheirlightpassedclosetoaheavyobject(the sun)during a total eclipse and compare them with their normal posi-tions in thenightskywhentheir lightdidnotpassnear thesun.Themeasurementsconfirmedthatthelightwasdeflected,andthemagnitudeofthedeflectionwasconsistentwithwhatwaspredictedfromthetheory.WhatwasremarkableaboutEinstein’stheorywasits vulnerability. The results of the eclipse measurements wouldnothavebeenexpectedonapriorigrounds,andiftheyhadbeendifferent,forexample,evenifthelighthadbeendeflectedbutnotbytherightmagnitude,thetheorywouldhavebeenrefuted.ThisledPopper to conclude that the criterionofa scientific theory isthat it must be refutable (or falsifiable). Using this criterion, thepsychological theories of Adler and Freud failed, because noexperiment could be conceived that could refute them. This didnotmeanthatAdlerandFreudwerenotseeingmanythingscor-rectly, simply that their theories did not qualify as scientific. Inthe case of the theoryof Marx, the original theorywas testable,butPopperassertedthatithadbeentestedandrefuted.However,in order to preserve it, its adherents had reinterpreted both thetheoryandtheevidenceinordertomakethemagree.Inthisway,theymadethetheoryirrefutableandthusdestroyeditsscientificstatus.InthecaseofEinstein’stheory,itwastestableandrefutableasshownbythe1919experiment.

Demarcation: A Criterion to Distinguish between Science and Nonscience
Popper’sobjectivewasnottohaveacriteriontodecidewhetheratheory(orhypothesis)wastrueorfalsebuttodistinguishbetweenscienceandnonscience(orpseudoscience).Hereferredtotheprob-lem of drawing a line between science and pseudoscience as the“problemofdemarcation.”Thecriterionofrefutabilitywasthusthesolutiontotheproblemofdemarcation.
Poppersummarizedhisconclusionsasfollows:
Itiseasytoobtainconfirmations,orverifications,fornearlyeverytheory—ifwelookforconfirmations.
Confirmations should count only if they are the result ofriskypredictions;that is tosay, if,unenlightenedbythethe-ory in question, we should have expected an event whichwasincompatiblewiththetheory—aneventthatwouldhaverefutedthetheory.
Every“good”scientifictheoryisaprohibition;itforbidscer-tainthingstohappen.Themoreatheoryforbids,thebetteritis.
Atheorywhichisnotrefutablebyanyconceivableeventisnon-scientific.Irrefutabilityisnotavirtueofatheory(assomepeopleoftenthink)butavice.
Everygenuinetestofatheoryisanattempttofalsifyit,ortorefuteit.Testabilityisfalsifiability,buttherearedegreesoftestability; some theoriesaremore testable,moreexposed torefutation,thanothers;theytake,asitwere,greaterrisks.
Confirmingevidenceshouldnotcountexceptwhenitistheresultofagenuinetestofthetheory;andthismeansthatitcanbepresentedasaseriousbutunsuccessfulattempttofalsifythetheory.(Inowspeakinsuchcasesof“corroboratingevidence”).
Somegenuinelytestabletheories,whenfoundtobefalse,arestillheldbytheiradmirers—forexamplebyintroducingsomeauxiliary assumption, or by reinterpreting the theory ad hocin sucha way that it escapes refutation.Such aprocedure isalwayspossible,butitrescuesthetheoryfromrefutationonlyat the price of destroying, or at least, lowering its scientificstatus.(Popper,1992,pp.36–37)
With this insight, Popper rejected induction as a valid scientificmethod.Scientificknowledgeproceededfromtheorytoobservation,
Scientific Research as a Career

not from observation to theory as the proponents of inductionasserted. Instead of waiting for regularities to appear, scientistsactivelytrytoimposeregularitiesonnature.Thisleadstocriticaltests (i.e., observations that are not arbitrary but are undertakenwiththeintentionoftestingahypothesisbyobtaining,ifpossible,a refutation). It isunlikely thatanyonewouldhavecomparedtheapparentpositionsofstarsduringaneclipseofthesunwiththeirnormalpositionsifthetheoryofrelativityhadnotbeenconceived.Ofcourse,naturefrequentlyresiststheimpositionofaconceptualview,andthehypothesisthatfollowsfromitisrefuted.Inscience,it isimportanttorealizethatatheorycanbeshowntobefalseifexperi-mental results fail to agree with what was predicted. Conversely,however, it can never be shown that a theory is true beyond anydoubt.Iftheresultsofexperimentsfailtorefuteatheory,allthatcanbesaidisthatthetheoryhasbeencorroboratedandmayprovision-allybeheldtobecorrect.

Exploratory Work Preceding Hypotheses

A certaindegree of understanding of thearea of study has tobe obtained.During exploratory work, scientists proceed to gather informa-tion. As new facts are uncovered, critical thinking may lead toconjectures that are evaluated for their validity. Frequently, theseinitialconjectureshavetobedismissediftheyfailtoexplainalltheobservations.Atsomestage,asaresultofcarefulobservationandfocusedthinking, thescientistmaygaininspirational insight intotheproblembeingtackled.

How Scientific Research Can Be Put Off Track Deliberately

Piltdown ManIn1912, fragmentsof a skull and jawbonewere recovered fromagravel pit at Piltdown, a village in East Wessex, England. Manyexperts of the day believed the bones were those of a previouslyunknownformofearlyhuman.Thefindingoftheremainshasnotbeenclearlydocumented,butCharlesDawsonwasthefirsttopresenttheevidence,claimingtohavebeengiventheskullbyaworkmanatthePiltdowngravelpit.Atthetime,therewasgreatinterestintheevolutionofhumans,anditwasthoughtthattherehadbeenagapinthefossilrecordsbetweenearlyhominoidsandmodernhumans.ThePiltdownManwasproposedbymanytofitthis“missinglink.”Subsequently,DawsonwasaccompaniedtothesitebyArthurSmithWoodward,whowasinchargeofthegeologicaldepartmentattheBritishMuseum,andtheyfoundfurtherfragments.Woodwardpro-posedthatPiltdownManwasthemissinglinkbetweenapesandhumans.

The pressure placed on scientiststo meet goals tends to reduce the freedom and time for the deepthoughtrequiredtodeveloptheoreticalconcepts.Intheevaluationsof scientists, a high weight is placed on the number of publishedpapers.

Theavailabilityofdatabasesandnewcomputerprogramsisfacili-tating these determinations.

Detachment
Anessentialqualityforaresearchscientist todevelopis theabil-ity to separate or detach oneself from one’s own theories. This issomethingthatgoesagainsthumannatureandcannotbelearnedfrom a textbook. It can be learned only through experience byforming hypotheses, having them refuted by critical experimentsorrationalarguments,acceptingthattheywerewrong,andgoingonto formulatenewhypotheses.Iwould like torecountmyownexperienceinthisregard.WhileIwasagraduateresearchstudent,I obtained results that caused me to reach an interpretation thatwasdifferentthanwhathadbeengenerallyaccepted.WhenItookthis“newtheory”tomysupervisor,helistenedpatiently.Hethensuggested that if my ideas were correct, if I did a certain experi-ment,itshouldresultinaconfirmation.Ithoughtatthetimethatitwasunnecessarytodotheexperiment,asIfeltthattheevidenceIhadwassufficientlystrong.However,Idecidedtodotheexperi-mentsothat Icouldgotomysupervisorandsay“Itoldyouso.”Unfortunately, the results of the experiment did not turn out asI expectedand,infact,showedthatmyinterpretationcouldnotbecorrect.

My mother made me a scientist without ever intending to. Every Jewish mother in Brooklyn would ask her child after school “So? Did you learn anything today?” But not my mother. “Izzy” she would say, “Did you ask a good question today?” That difference—asking good questions—made me become a scientist.*(IsidorIsaacRabi)
Science is facts; just as houses are made of stones, so is science made of facts, but a pile of stones is not a house and a collection of facts is not necessarily science.†(HenriPoincare)
At Princeton, Albert Einstein was more like a kindly uncle. When he arrived in 1935, he was asked what he would require for his study. He replied, “A desk, some pads, a pencil, and a large wastebasket to hold all of my mistakes.”‡
The real scientist … is ready to bear privation and, if need be, star-vation, rather than let anyone dictate to him which direction his work must take.§(AlbertSzent-Gyorgi)
It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.¶(KonradLorenz)
In science it often happens that scientists say, “You know that’s a really good argument; my position is mistaken.” And then they actually change their minds and you never hear that old view from them again. They really do it. It doesn’t happen as often as it should, because scientists are human and change is sometimes painful. But it does happen every day. I cannot recall the last time something like that happened in politics or religion.**(CarlSagan)

Commonwealth Scientific and Industrial Research Organization (CSIRO) of Australia
The CSIRO was established under an Act of Parliament in 1949,beinganextensionofthepreviousCSIR(CouncilforScientificandIndustrialResearch). Itsaimwas toprovideresearch for industryand government to enhance economic development. It was struc-turedintodivisionsandsmallergroupsorunits,eachfocusedonaspecific industry,andwasheadedbyanexecutivemanagementcouncilconsistingofafull-timechairmanandfourfull-timemem-berswithasmallnumberofpart-timemembersdrawnfrombusi-nessanduniversitybackgrounds.Allthefull-timemembersweresenior scientistsand employees ofCSIRO.Divisionswere headedbychiefs,andunitsbyofficers-in-chargewhoreporteddirectlytoamemberoftheexecutivemanagementcouncil.Inafewdecadesfol-lowingitsformation,theorganizationflourishedandmadeimpor-tantcontributionstoAustralianindustriesaswellastofundamentalresearch such as radio astronomy. Later, its activities expandedintootherareasaffecting thecommunity, includingenvironment,humannutrition,urbanandruralplanning,andwatersupplies.
Reviews of CSIRO
CSIRO has been subjected to numerous reviews since its estab-lishment,butIwillmentiononlytwothathaveresultedinappre-ciable reorganization. Asa resultof the 1977 report by theBirchCommittee, divisions were grouped into five institutes, eachheadedbyadirectorwhoserolewasmanagerial (CSIROAnnualReport1977/78,p. 11).Divisionalchiefsreportedtoinstitutedirec-tors,who in turn reported to theexecutivemanagement council.Inthedecadefollowingthisreview,ariseofeconomicrationalismwasseen.Economic rationalism isanAustraliantermforadogmathat resembles what has been called Thatcherism in the UnitedKingdomandReaganomicsintheUnitedStates.Thiseconomicman-agement approach, which has gained momentum, particularly inEnglish-speakingWesterncountries,placesastrongrelianceontheworkingsofthefreemarket.

Effects of McKinsey Review
Inthispolitical-economicclimate,theglobalmanagementconsult-ing firm McKinsey and Company was contracted to carry out areviewofCSIROin1986.Theacceptanceoftheirrecommendationsresultedinthemostfar-reachingrestructuringinCSIRO’shistory.Following from the McKinsey report, the executive managementcouncil, made up of senior CSIRO scientists, was abolished, andtheorganizationwasplacedunderthecontroloftheCSIROboard,whosemembersweredrawnlargelyfromthebusinessworld.Thefive institutesestablished in 1979 following theBirch report werereplacedwithsixinstitutes,eachrelatedtoasectionofthenationaleconomy.Theprevious41divisionswerereducedto32divisions,and all units were amalgamated into existing divisions. It wasfurther proposed that CSIRO should find more of its funds fromnon-Treasury sources. One of the recommendations adopted wasthatavigorousprogramofmanagementtrainingforstaffbeintro-duced(CSIROAnnualReport1986/87,p.7).

Performance Criteria for Scientists
Theperformance criteria for technical and research staff in someresearch organizations are formulated by administrators. At thebeginning of the review period, staff members are required todocument such things asobjectives, tasks to be performed, time-lines,milestones,andexpectedoutcomes.Attheendofthereviewperiod,theexpectedoutcomesandmilestonesareevaluatedagainsttheobjectives.Althoughsomeflexibilitymaybeallowed,thisratherrigid framework conflicts with the way that scientific researchshouldproceedaccordingtoastatementbyAlbertSzent-Gyorgiinregardtograntproposals.Inanarticleentitled“ResearchGrants,”Szent-Gyorgi(1974)wrote,
Researchmeansgoing into theunknown,which demandsapioneering spirit.This spirit isnowstrangled by theway inwhich themain federalbiomedicalgrantingagency, theU.S.National InstituteofHealth(NIH)distributes itsgrants.Theunknown is unknown because one does not know what isthere.

The same reasoning applies to the performance reviews ofresearchscientists.Foranyproject,aresearcherneedstobeginwithgoals,buttheseneedtobeflexiblesothatwhennewinsightsintotheproblemaregained,thedirectionoftheresearchcanbeeasilychanged.Thisisnotpossiblewiththerigidstructureimposedbymanagerialism.Asaresult,scientistsareoftenstraightjacketedintheir projects.

Influence of Managerialism on Scientists
Confirmation of the inappropriateness of applying managementideologytoscientificresearchcomesfromthelossofmoraleandjobsatisfactionandthesteepincreaseinstresswithitsaccompany-ing health problems suffered by CSIRO staff since the adventof managerial policies (Rees, 1995). The problems stem from anunhealthy work environment. Diane Cory (1998), in an articleentitled “The Killing Fields: Institutions and the Death of OurSpirits,”wrotethefollowing:
There is a lie that must be named and a truth that must betold.Ourinstitutionsarekillingourspirits.Weareallowingittohappen.Inexchangeforanillusionofpowerandcontrol,safetyandsecurity,wehavebetrayedoursoulsbecauseweareafraid. We are afraid to think for ourselves inside organiza-tions.Weareafraidofourbossesandourbosses’bosses.Weareafraidofourcolleaguesandwhattheymightsayandhowtheymightbetrayusinmeetingsorbehindourbacks.Weareafraidwewon’tmeetourdeadlines.Weareafraidofforeigncompetitors.Weareafraid to“dreamgreatdreams.” Weareafraidtobekind.
This, I believe, is an apt description of the working environ-mentthathasbeenfoistedonCSIROasaresultoftheimpositionof managerialism.

Servant Leadership
The third of the above qualities emphasizes leaders’ concerns fortheirsubordinates,anattributethatleadsnaturallytoaconceptthathasachievedprominenceinrecentdecades,thatofservantleader-ship. This was introduced by Robert Greenleaf and described inseveralpublications(GreenleafandSpears,2002;Frick,2004).Sincehispassingonin1990,othershavecontinuedhispioneeringworkat the Greenleaf Center for Servant-Leadership in Indianapolis,Indiana. The ideas of servant leadership have been disseminatedbyothers in theformofarticlesandconferencepresentationsandhavebeenintroducedintosomeorganizations.Briefly,theconceptisthattheservantleaderisaservantfirstbutlaterchoosestoaspiretoleadership.GreenleafreceivedinspirationfromreadingHermanHesse’sThe Journey to the East(1956).Inthisstory,agroupofmensetoutonaspiritualjourneysponsoredbyanOrder.Oneofthegroup,Leo,wastheservantwhosustainedothermembersofthegroupbyhis spirit.The journeywasgoingwelluntilLeodisappeared.Thegroupthenfellintodisarray,andthejourneywasabandoned.Later,thenarratorofthestory,oneofthegroup,afterwanderingforyears,istakenintotheOrderthathadsponsoredthejourney.HethenmetupagainwithLeowhomhehadknownasaservantbutnowdiscov-eredthathewastheguidingspiritoftheOrderanditsnobleleader.
The essential feature of servant-leadership is that the leaders’experiencesasservantsfitthemtounderstandhowtoserveothers.Agoodservanttriestoinsurethatotherpeoples’needsarebeingserved.Inscience,itfollowsthattheleadergivesprioritytothebestinterests of the scientists. This means trying to insure the condi-tions for each scientist’s creative talent to flourish and to removeobstaclestothisobjective.AccordingtoGreenleaf,thebesttestofservantleadershipis“Dothoseservedgrowaspersons?Dothey,while being served, become healthier, wiser, freer, more autono-mous,morelikelythemselvestobecomeservants?”Inregardtothefuture,Greenleaf(1998)believedthat

Ofcourse,theseideaswillbevigorouslyopposedbythosewhobelieveincoercivepowerandcontrolratherthanatrustbasedonmutualaccord.Noteveryonecanfit intoa servant-leader culture,andthiswasadmittedbyGreenleaf.Inhisbiographicalnotes(citedbyFrick,1998),hereferstohisforemantellingayoungworker,“Youknow,ifafellowisanS.O.B.,deepdowninside,hehadjustbettergoaheadandbeone,becauseifhetriestobesomethingelse,hewilllikelybeseenasbothahypocriteandanS.O.B.,andthat’sworse”(pp.354–355).
The Inverted Pyramid
The concept of servant leadership leads to a structure that is, tosome extent, opposite to that found in most organizations. TheusualstructurefororganizationsisapyramidinwhichtheCEOisattheapex,andsuccessivelayersofmanagementmovedownwards.When it comes to matters of vision, mission, values, and settingof major goals, it is essential that the pyramid remains upright(Blanshard,1998).However,Blanshardsuggeststhattheimplemen-tationofpoliciescanoftenbemadeinabetterwayifthepyramidisinverted.Whenthishappens,thoseatthetopoftheorganizationbecomethosewhointerfacewiththecustomers.Thoseatthebottomofthepyramidarenowthetopmanagers.Theirroleisthentosup-port thoseat thecustomer interfaceandhelp themtoaccomplishtheirgoals.Thesegoalsaregenerallytoprovideexcellentservicetothecustomers.Wehaveallexperienced the frustrationofdealingwithbureaucracywhenwehavebeenunabletohaveourreasonablerequestssatisfiedbecausethepeoplewedealwitharefarremovedfromthetopmanagementandhavenoautonomy.

What are in dispute are the conditions placed onscientists,purportedlytoachievetheresearchgoals.Forexample,governmentrepresentativesprimarilycomefromprofessionsotherthan science and therefore do not have a deep understanding ofscience.Thepromisesofmanagerialideologyareappealing.Greaterefficiencyanddoingmorewithlessseemtobeplausiblegoals.Ifitcomeswithdemoralizationandanunpleasantworkenvironment,itmightbearguedthatthisisthecostofeconomicsuccess.Butiseconomicsuccessreallyachievedunderthesecircumstances?If thecreativity of scientists is curtailed, can optimum economic suc-cessresult?

Uranium occurred naturally in two minerals: pitch-blendeandtorbernite(alsoknownaschalcolite).Itwasfoundthatpitchblende was about four times as radioactive as uranium, andtorbernitewastwiceasradioactive.Itwasdeducedfromthis thatthesetwomineralsmustcontainsmallquantitiesofsomeothersub-stancethatwasmoreactivethanuranium.PierreCuriejoinedhiswife in the work, and together, they announced in 1898 the exis-tenceofanelementthattheynamedpolonium(inhonorofhernativePoland).Inthesameyear,theyannouncedtheexistenceofasecondelementthattheynamedradium,foritsintenseradioactivity.
Pitchblende is a complex mineral, and the chemical separationof itsconstituentswasahugelyarduoustask.Poloniumwasrela-tivelyeasy,butradiumwasmoredifficult.Chemically,itresembledtheelementbarium,andthesetwoelementswerebothpresentinpitchblende.TheCuriesundertookthedauntingtaskofseparatingout radium salts by differential crystallization. The problem wasthat the concentration of radium in pitchblende was much lowerthanhadbeenanticipated.Fromatonofpitchblende,onetenthofa gramof radiumchloride was separated in1902. By1910, MarieCurie isolated the pure radium metal.

Charles Darwin (1809–1882)
Charles Darwin was born at Shrewsbury, England, the son of adoctor.HebegantostudymedicineatEdinburghbutdidnotpursuea medical career. He transferred to Cambridge to train for theministry.AtCambridge,hebefriendedJohnHenslow,abiologypro-fessor,andAdamSedgwick,ageologyprofessor,andwasmotivatedtobecomeinterestedinbiologyandgeology.ThroughtheinfluenceofHenslow,hewasinvitedtoaccompanyanexpeditionontheHMSBeagle,ashiporganizedbytheAdmiraltytochartthewatersoftheSouthSeas,underayoungcaptain,RobertFitzroy.The cruiseoftheBeagleextendedtoalmostfiveyears(1831to1836).Thegoodfacilitieson theshipand the timespentexploringnew landsgaveDarwina wonderful opportunity to make observations and to collectspecimens,whichformedthebasisforthetheorieshewastodevelopovermanyyearsafterthereturnoftheBeagletoEngland.Duringtheexpedition,Darwinspentmuchofthetimeonland,whiletheBeagle charteredthecoastsofSouthAmerica,surroundingislands,andasfaras Australia.
During the voyage of the Beagle, Darwin read avidly from thebooksintheship’slibraryaswellasthosehebroughtalonghimself.Onebook,CharlesLyell’sPrinciples of Geology(1830–1833),influencedhis thinking. Lyell proposed that the earth’s geology had changedgraduallyover longperiodsof timeasa resultofcumulative localeventssuchasearthquakes,volcaniceruptions,erosion,anddepositsofsediments.Thisdifferedfromthecurrentlyheldviewthatchangesoccurred through violent, short-lived events such as the raising ofmountains.Darwin’sobservations tended to confirmLyell’sviews.Forexample,inSaoTigre,avolcanicislandabout1800milessouth-westoftheCanaryIslands,hededucedfromthesequenceofsedi-mentsthattheisland’ssurfacehadbeenformedbyasuccessionofvolcanicevents,interspersedwithsubsidenceandbuildingupoveralongtime,andnotasingleviolentone.Hedid,however,disagree

Hisgeologicalworkbroughthimrecognitioninscientificcircles,but the problem that particularly occupied Darwin’s attention wasthequestionofhowdifferentspeciesoforganismsoriginated.DuringhisvoyageontheBeagle,hewasintriguedbymanyobservations.Forexample,inSouthAmerica,hehadfoundfossilsofarmadillosthatwerenowextinctbutweresimilarbutnotidenticaltothosepresentlyexisting.InArgentina,thegiantostriches(rhias)ontheplainsweredifferentthanthesmallerspeciesfoundinPatagonia,andbothweredifferentthantheAfricanostrich.Thus,inthesetwoexamples,specieswereseentovaryasaresultofbothtimeandgeographicallocationchanges.Theprevailingviewwasthatasonespeciesdisappeared,anewspeciessuddenlycameintoexistencetoreplaceit.Darwinfoundthisunacceptable,andhisthinkingturnedtotransmutation(i.e.,theideathatspecieschangedfromonelocationtoanotherorfromoneera to thenextbygradual changesover longperiods thatmaybethousandsormillionsofyears).ThechallengingquestionDarwinponderedwasbywhatmechanismthiswasachieved.
Afterhis return from theBeagle voyage,hehadsent thespeci-mens he had collected to experts in Cambridge and London foranalysis.Heworkedontheinformationhegotbacktogetherwiththenoteshehadcompiledduringhisvoyageandconcentratedonfinding a mechanism for transmutation of species. At this time,hewas influencedbyreadingThomasMalthus’“AnEssayonthePrinciplesofPopulation”(1978).Inthisessay,Malthusproposedthatpopulationgrowthwouldbedecreasedby limits on foodsupply.Darwinrealizedthatinthestruggleforexistence,favorablevaria-tionswouldtendtobepreservedandunfavorableonesdestroyed.Theresultovertimewouldbetheformationofnewspecies.Thus,anindividualwithenhancedcharacteristicssuchasasharperbeakor a brighter colormight be better able to surviveand reproducethanothers.ThisessentiallywasthePrincipleofNaturalSelection.Itshiftedattentionfromdifferencesbetweenspeciestocompetitionwithin species.Darwinresistedpublicationofhis ideas formanyyears,duringwhichtimeheconsultedextensivelywithplantand

In 1609, there was to be a change that dramatically affectedGalileo’s career as well as subsequent science. An instrument(an earlyformof telescope)hadbeen inventedin theNetherlandsthat magnified images of distant objects.

LouisPasteurwasborn inDole,France, thesonofapoor tanner.He gained hisdoctorate in 1847at the École Normale SupérieureinParis,wherehestartedhis researchstudyingcrystalstructure,focusing on tartaric acid. He found that an aqueous solution oftartaricacidfromlivingthings,suchasgrapeproducts,rotatedtheplaneofpolarized light.A solutionof tartaric acid that hadbeenchemicallysynthesized,ontheotherhand,didnotshowthiseffect,eventhoughitselementalcompositionandchemicalreactionswereidentical.Pasteurresolvedthispuzzlebyseparatingthesynthetictartaricacidintotwocomponents(isomers),eachofwhichrotatedtheplaneofpolarizedlightbutinoppositedirections.Thisproperty,calledchirality,iscausedbymoleculesthatlackaplaneofsymme-try and have nonsuperimposable mirror images. Pasteur showedthat, in general, where biological molecules have optical isomers,onlyoneoftheformswillbebiologicallyactive.
After several years teaching and carrying out research at DijonandStrasbourg,hetookthepositionofprofessorofchemistryattheUniversityofLille.HerehecontinuedworkonfermentationthathehadstartedatStrasbourg.Atthattime,theconsensuswasthattheprocessthatcausedspoilageofbeveragessuchasbeer,wine,andmilkwascausedbyspontaneouscreation.Pasteurexposedboiledbrothstoairinflasksthatweredesignedtopreventparticlesfromentering.Nothinggrewunlessthevesselwasbroken,showingthatorganisms(germs) that grew in thebroths came from outside, supposedly assporesondust.Thisdebunkedthewidelyacceptedmythofsponta-neousgenerationandgavestrongsupporttothegermtheory.Pasteurinventedtheprocessinwhichbeverageswereheatedtokillbacteriaandmoldsthatwerepresent,aprocessaptlycalledpasteurization.

To beapproved, the proposals must convince peer reviewers that thework is feasibleand that theobjectives canbeachieved.

“This will be a very important resource for beginning scientists so they can see what thefield is like, especially this all important topic of how to build prestige and a track recordfor excellence.”
—John D 'Angelo, Alfred University, New York
Describing the philosophy of the scientific method and the training and professional characteristicsneeded for a successful career, Scientific Research as a Career is a comprehensive “how-to”guide for the aspiring scientist. Based on the author’s experience both as a scientist in a researchorganization and as a university mentor, the book covers:
• The interaction between management and leadership principles and scientific research
• Qualifications and attributes usually required to become a successful researcher
• History, application, and prerequisites of the scientific method and scientific progress
• Exploration of the careers of pivotal and influential scientists
The author highlights the importance of networking and the value of forming contacts withcolleagues, joining scientific associations, attending conferences, making presentations, andacting as chairs for conference sessions. He also touches on the many areas outside of “thescience” that readers are likely to encounter during their career, such as mentoring, supervisingresearch students, and managing a group. The book clearly delineates not only the challengescurrently facing scientists, but also how to overcome them and achieve success in their careers.
