Geniuses

In1905,AlbertEinsteindevelopedthetheoryofspecialrelativity.Healsoprovedthatatomsexistandfiguredoutthatlightbehavesasbothaparticleandawave.Totopitalloff,hedevelopedhisfamousequationE=mcc,whichdescribestherelationshipbetweenmatterandenergy,thesameyear.Hewasonly26yearsold.

Withoutadoubt,Einsteinwasagenius.SowasIsaacNewton-asanyfanof"StarTrek".TheNextGenerationcansayheinventedphysics.Healsoplayedabigroleinthedevelopmentofcalculus,whichsomepeoplehavetroublecomprehendingevenafterextensiveclassroomstudy.Anothergenius,WolfgangAmadeusMozart,startedcomposingmusicwhenhewas5yearsold.Mozartwrotehundredsofpiecesbeforehisdeathin1760atage35.

Accordingtoconventionalwisdom,geniusesaredifferentfromeveryoneelse.Theycanthinkfasterandbetterthanotherpeople,Inaddition,manypeoplethinkthatallthatextrabrainpowerleadstoeccentricorquirkybehavior.Andalthoughgeniusesarefairlyeasytospot,definingexactlywhatmakesonepersonageniusisalittletrickier.Figuringouthowthatpersonbecameageniusisharderstill.

Therearetwobigthingsthatmakeitdifficulttostudygenius:

Thegeniuslabelissubjective.Somepeopleinsistthatanyonewithanintelligencequotient(IQ)higherthanacertainvalueisagenius.OthersfeelthatIQtestsmeasureonlyalimitedpartofaperson'stotalintelligence.Somebelievehightestscoreshavelittletodowithrealgenius.

Geniusisabig-pictureconcept.Mostscientificandmedicalinquiries,ontheotherband,examinedetails.Aconceptassubjectiveasgeniusisn'teasytoquantify,analyzeorstudy.

So,whenexploringhowgeniuseswork,it'sagoodideatostartbydefiningpreciselywhatageniusis.Forthepurposeofthisarticle,ageniusisn'tsimplysomeonewithanexceptionallyhighIQ.Instead,ageniusisanextraordinarilyintelligentpersonwhobreaksnewgroundwithdiscoveries,inventionsorworksofart.Usually,agenius'workchangesthewaypeopleviewtheworldorthefieldinwhichtheworktookplace.Inotherwords,ageniusmustbebothintelligentandabletousethatintelligenceinaproductiveorimpressiveway.

TheBirthofMultitasking

Thescienceofinterruptionsbeganmorethan100yearsagowiththeemergenceoftelegraphoperators—thefirsthigh-stress,time-sensitiveinformation-technologyjobs.Psychologistsdiscoveredthatifsomeonespoketoatelegraphoperatorwhilehewaskeyingamessage,theoperatorwasmorelikelytomakeerrors.Later,psychologistsdeterminedthatwheneverworkersneededtofocusonajobthatrequiredthemonitoringofdata,presentationwasallimportant.Usingthisknowledge,cockpits(駛艙)forfighterpilotswerecarefullydesignedsothateachdialandmetercouldbereadwithjustaglance.

Still,suchissuesseemedremotefromthelivesofeverydayworkers.Then,inthe1990s,computersbegantoexperiencearapidincreaseinspeedandpower."Multitasking"wasborn;insteadofsimplyworkingononeprogramforhoursatatime,acomputeruserworksonseveralsimultaneously.Officeworkersnowstareatcomputerscreensofoverwhelmingcomplexity,astheyjuggle(操縱)messages,textdocuments,PowerPointpresentationsandwebbrowsers.Inthemodernofficeweareallfighterpilots.
