Heisenberg, Werner

"The problem of the relevance of the quantum mechanical laws to the description of macroscopic events is very difficult."

"I have always hated machinery, and I hate it the more the more ingenious it is."

"One cannot say that the statistical interpretation of quantum theory is not rational, for it is based on classical logic."

"If we want to make progress, we must leave the past behind."

"The key to the future is the past, understood rightly."

"Nature does not allow us to know anything about the world without changing it by the act of knowing."

"The laws of physics are the canvas God laid down on which to paint his masterpiece."

"I am now convinced that theoretical physics is actual philosophy."

"Not only is the universe stranger than we imagine, it is stranger than we can imagine."

"What is important is to understand that the world is built on a quantum foundation."

"The hope that the future will be better is based on the hope that we learn from the past."

"When you change the way you look at things, the things you look at change."

"The physicist has to wander through the lonely land of thoughts and numbers."

"Scientific reasoning is a dialogue between theory and experiment."

"Nature is the ultimate teacher; she reveals her secrets only to those who listen."

"The understanding of nature requires both mathematics and intuition."

"What I have learned is to love the mystery more than the solution."

"The world is not only a collection of particles but a tapestry of relationships."

"To understand the atom is to understand the universe."

"Faith and knowledge are not opposites but complements."

"We are not mere spectators of nature but participants in its unfolding."

"The beauty of nature lies not in what we see but in how we understand it."

"The present moment is where science and philosophy meet."

"To be a scientist, one must cultivate both doubt and wonder."

"The greatest discoveries come from the willingness to question everything."

"A scientist's responsibility is to seek truth, not comfort."

"The universe speaks in the language of mathematics, but it dreams in the language of meaning."

"What separates the great scientist from the merely clever one is the ability to ask the right question."

"Nature does not yield her secrets to the arrogant, only to the humble."

"The moment we think we understand nature, we have stopped understanding it."
