Quote by Max Delbrück
"Persistence in the face of experimental failure is what separates great scientists from good ones."
More from Max Delbrück
"Science is a way of thinking much more than it is a body of knowledge."
"The real problem is that the way the world works, as described by modern physics, cannot be adequately and fundamentally explained in terms of classical concepts."
"A scientist's aim in writing is to inform."
"The essential question is not whether the mind can be explained by physics, but whether physics can be adequately explained without reference to the mind."
