What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.

Interpretation

What this quote means

This quote emphasizes the active role of the observer in quantum physics, contrasting it with the passive experience of classical physics.

Wolfgang Pauli highlights the significance of the observer in quantum physics, suggesting that the act of observation influences physical events. Unlike classical physics, where the observer is seen as a mere spectator, quantum physics assigns a more dynamic and interactive role to observers, indicating that their involvement can shape the reality they observe.

The layman always means, when he says "reality" that he is speaking of something self-evidently known; whereas to me it seems the most important and exceedingly difficult task of our time is to work on the construction of a new idea of reality.

Physics is very muddled again at the moment; it is much too hard for me anyway, and I wish I were a movie comedian or something like that and had never heard anything about physics!

The fact that the author thinks slowly is not serious, but the fact that he publishes faster than he thinks is inexcusable.

I confess, that very different from you, I do find sometimes scientific inspiration in mysticism ... but this is counterbalanced by an immediate sense for mathematics.

Well, biology today as I see it has an amiable look - quite different from the 19th-century view that the whole arrangement of nature is hostile, 'red in tooth and claw.' That came about because people misread Darwin's 'survival of the fittest.'

Contaminated water is not a problem limited to Flint. Think of New Jersey, where school fountains were found to contain unsafe levels of lead.
