Werner Heisenberg

Quotes

• “The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.”
• “Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.”
• “Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.”
• “An expert is someone who knows some of the worst mistakes that can be made in his subject, and how to avoid them.”
• “In general, scientific progress calls for no more than the absorption and elaboration of new ideas — and this is a call most scientists are happy to heed.”
• “Can you, or anyone else, reach the central order of things or events, whose existence seems beyond doubt, as directly as you can reach the soul of another human being? I am using the term 'soul' quite deliberately so as not to be misunderstood. If you put your question like that, I would say yes. ... the word 'soul' refers to the central order, to the inner core of a being whose outer manifestations may be highly diverse and pass our understanding.”
