It is seen that both matter and radiation possess a remarkable duality of character, as they sometimes exhibit the properties of waves, at other times those of particles. Now, it is obvious that a thing cannot be a form of wave motion and composed of particles at the same time - the two concepts are too different.
Interpretation
Matter and radiation can behave both like waves and particles, revealing a fundamental duality.
This quote by Werner Heisenberg highlights the intriguing dual nature of matter and radiation in quantum physics, where entities can exhibit characteristics of both waves and particles. Heisenberg emphasizes the paradoxical nature of these concepts, suggesting that they represent fundamentally different ways of understanding physical phenomena, yet coexist in the quantum realm, challenging our classical intuitions about the universe.
In practice
In a physics lecture discussing quantum mechanics, this quote could be used to illustrate the concept of wave-particle duality.
Although the theory of relativity makes the greatest of demands on the ability for abstract thought, still it fulfills the traditional requirements of science insofar as it permits a division of the world into subject and object (observer and observed) and, hence, a clear formulation of the law of causality.
It was about three o'clock at night when the final result of the calculation [which gave birth to quantum mechanics] lay before me ... At first I was deeply shaken ... I was so excited that I could not think of sleep. So I left the house ... and awaited the sunrise on top of a rock.
It is generally believed that our science is empirical and that we draw our concepts and our mathematical constructs from the empirical data. If this were the whole truth, we should, when entering into a new field, introduce only such quantities as can directly be observed, and formulate natural laws only by means of these quantities.
When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.
The end of the First World War had thrown Germany's youth into great turmoil. The reins of power had fallen from the hands of a deeply disillusioned older generation, and the younger ones drew together in larger and smaller groups to blaze new paths or, at least, to discover a new star to steer by.
The Same organizing forces that have shaped nature in all her forms are also responsible for the structure of our minds.
While I thought myself employed only in forming a nomenclature, and while I proposed to myself nothing more than to improve the chemical language, my work transformed itself by degrees, without my being able to prevent it, into a treatise upon the Elements of Chemistry.
Our goal is not to completely eradicate the infection - that would be very difficult - but to produce a vaccine that will prevent not infection but disease. I think this is more possible.
Through every rift of discovery some seeming anomaly drops out of the darkness, and falls, as a golden link into the great chain of order.
[Decoding the human genome sequence] is the most significant undertaking that we have mounted so far in an organized way in all of science. I believe that reading our blueprints, cataloguing our own instruction book, will be judged by history as more significant than even splitting the atom or going to the moon.
There are three stages in scientific discovery. First, people deny that it is true, then they deny that it is important; finally they credit the wrong person.
At Virgin, we have always backed the power of the entrepreneur and inventor to find solutions to tricky problems. Why should climate change and the battle against carbon be any different?
