"The Copenhagen interpretation of quantum mechanics starts from the paradox that we describe our experiments in terms of classical physics, and we describe the elementary particles in terms of quantum …"
"Every word or concept, clear as it may seem to be, has only a limited range of applicability."
"The concept of the objective reality of the elementary particles has thus evaporated not into the fog of some new, unclear, or not yet understood reality concept, but into the transparent clarity of a…"
"I was forced to find a new way of expressing the fundamental laws of nature, one which would not rely on the outdated concepts of classical physics."
"Can nature possibly be so absurd as it seemed to us in these atomic experiments?"

Understanding this quote
What it means
Real expertise is not about knowing everything or being flawless. Instead, it comes from having made or witnessed the major errors in a field and learning how to steer around them. A true expert has internalized the common pitfalls, dead ends, and traps that trip up newcomers, and uses that hard-won knowledge to navigate problems without repeating those costly mistakes themselves.
Relevance to Werner Heisenberg
Heisenberg built quantum mechanics through trial, error, and repeatedly revising failed assumptions about atomic structure. His uncertainty principle itself reframed what science could reliably know, acknowledging inherent limits. As a young physicist mentored by Bohr and Born, he learned by watching giants correct each other's blunders. His controversial wartime leadership of Germany's nuclear program also shows how expertise involves recognizing where catastrophic miscalculations lie.
The era
Heisenberg worked through the 1920s quantum revolution, when classical physics was collapsing and an entire generation of scientists had to abandon intuitive Newtonian assumptions. His era spanned two world wars, the rise and fall of Nazism, and the atomic age's dawn. Scientific progress demanded humility, since yesterday's certainties became today's errors. Postwar reconstruction of German science further underscored how acknowledging past mistakes was central to rebuilding credible expertise.
