“In the strict formulation of the law of causality—if we know the present, we can calculate the future—it is not the conclusion that is wrong but the premise. On an implication of the uncertainty principle.” IfsKnowsLawPrinciplesFutureConclusionUncertaintyStrictPremisesImplicationsCausalityUncertainty Principle Author:Werner Heisenberg
“The physicist may be satisfied when he has the mathematical scheme and knows how to use for the interpretation of the experiments. But he has to speak about his results also to non-physicists who will not be satisfied unless some explanation is given in plain language. Even for the physicist the description in plain language will be the criterion of the degree of understanding that has been reached.” KnowsMayHas BeensPhilosophyUseSpeakLanguageGivenUnderstandingResultsKnow HowDegreesPhysicsExperimentsSatisfiedMathematicalExplanationDescriptionInterpretationSchemesPhysicistCriteriaPlain Language Author:Werner Heisenberg
“Many people will tell you that an expert is someone who knows a great deal about the subject. To this I would object that one can never know much about any subject. I would much prefer the following definition: an expert is someone who knows some of the worst mistakes that can be made in the subject, and how to avoid them.” PeopleKnowsMadeDealsMistakeWorstSubjectsObjectsDefinitionsFollowingExperts Author:Werner Heisenberg

“The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.” KnowsGivingKindLawSciencePrinciplesExampleTheoryEssentialsAtomsRadiationQuantumUncertainUnitsPreciseProbabilityParticlesTheoreticalIncompleteIndicationEmissionsAlphasQuantum TheoryNucleusIncomplete Knowledge Author:Werner Heisenberg
