“At any one time there is a natural tendency among physicists to believe that we already know the essential ingredients of a comprehensive theory . But each time a new frontier of observation is broached we inevitably discover new phenomena which force us to modify substantially our previous conceptions. I believe this process to be unending, that the delights and challenges of unexpected discovery will continue always.” KnowsBelieveForceI BelieveProcessNaturalChallengesTheoryEssentialsDiscoveryDelightTendenciesObservationUnexpectedPhenomenonIngredientsConceptionOne TimePhysicistFrontiersComprehensiveUnendingNew Frontiers Author:Val Logsdon Fitch
“Commitment to the truth...means a relentless willingness to root out the ways we limit or deceive ourselves from seeing what is, and to continually challenge our theories of why things are the way they are. It means continually broadening our awareness. It also means continually deepening our understanding of the structures underlying current events.” WayMeanUnderstandingChallengesSeeingAwarenessEventsTheoryLimitsCommitmentRootsStructureCurrentsInsightWillingnessDeceivingRelentlessCurrent Events Author:Peter Senge
“Rebels and dissidents challenge the complacent belief in a just world, and, as the theory would predict, they are usually denigrated for their efforts. While they are alive, they may be called 'cantankerous,' 'crazy,' 'hysterical,' 'uppity,' or 'duped.' Dead, some of them become saints and heroes, the sterling characters of history. It's a matter of proportion. One angry rebel is crazy, three is a conspiracy, 50 is a movement.” WorldMayMatterCharacterThreeBeliefChallengesEffortAliveCrazyMovementTheoryHeroAngerAngrySaintActivismProportionRebellionRebelConspiracyComplacentHystericalDissidentsSterling Author:Carol Tavris
“You want sanity, democracy, community, an intact Earth? We can't get there, obeying Constitutional theory and law crafted by slave masters, imperialists, corporate masters, and Nature destroyers. We can't get there, kneeling before robed lawyers stockpiling class plunder precedent up their venerable sleeves. So isn't disobedience the challenge of our age?

“Any man who stands for progress has to criticize, disbelieve and challenge every item of the old faith. Item by item he has to reason out every nook and corner of the prevailing faith. If after considerable reasoning one is led to believe in any theory or philosophy, his faith is welcomed. His reasoning can be mistaken, wrong, misled and sometimes fallacious. But he is liable to correction because reason is the guiding star of his life. But mere faith and blind faith is dangerous: it dulls the brain, and makes a man reactionary.” IfsMenBelieveSometimesReasonPhilosophyStarsChallengesBrainProgressDangerousTheoryBlindMereCornersReasoningCriticizeMistakenItemsCorrectionsLiablePrevailingReactionariesBlind FaithMisledGuiding Stars Book:To make the deaf hear: ideology and programme of Bhagat Singh and his comrades Source: To make the deaf hear: ideology and programme of Bhagat Singh and his comrades
“I write my books to challenge my own feelings and theories. Perhaps most surprising was what I learned about rice farming. It was really interesting to think of how different Asian and Western cultures are as a result of the kinds of agricultural practices that our ancestors used for thousands of years. The life of a Chinese peasant in the Middle Ages was so dramatically different from the life of a European peasant - night and day different.” ThinkingWritingYearsKindBookDifferentFeelingsAgeUsedNightCultureChallengesMy OwnInterestingResultsPracticeMiddleTheoryWesternChineseAncestorSurprisingAsianFarmingMiddle AgesRicePeasantsReally InterestingWestern Culture Author:Malcolm Gladwell

“General relativity is in the old Newtonian framework where you predict what will happen, not the probability of what will happen. And putting together the probabilities of quantum mechanics with the certainty of general relativity, that's been the big challenge and that's why we have been excited about string theory, as it's one of the only approaches that can put it together.” Has BeensBigsHappensTogetherChallengesTheoryApproachExcitedCertaintyStringsQuantumProbabilityMechanicFrameworkRelativityQuantum MechanicsBig ChallengesString TheoryGeneral Relativity Author:Brian Greene

“Neither capitalism nor socialism is capable of meeting our unprecedented global challenges. Both came out of early industrial times, and we are now well into the post-industrial age.

“The caricature of science is that we hold tight to the theories we have, and shun challenges to them. That's just not true.
