That which is not measurable is not science. That which is not physics is stamp collecting.
All science is either physics or stamp collecting.
Interpretation
What this quote means
This quote implies that all sciences ultimately stem from physics, while some areas are merely about gathering data without deeper understanding.
Ernest Rutherford's quote suggests a hierarchy within the scientific disciplines, arguing that true science revolves around the principles of physics. It contrasts active scientific inquiry with merely collecting facts or data, implying that gathering information without interpretation or underlying principles does not contribute to true scientific understanding. This reflects the importance of fundamental theories that connect different branches of science.

I am a great believer in the simplicity of things and as you probably know I am inclined to hang on to broad & simple ideas like grim death until evidence is too strong for my tenacity.
Now I know what the atom looks like.
If your result needs a statistician then you should design a better experiment.
Should a young scientist working with me come to me after two years of such work and ask me what to do next, I would advise him to get out of science. After two years of work, if a man does not know what to do next, he will never make a real scientist.

Theory attracts practice as the magnet attracts iron.
All great scientists have, in a certain sense, been great artists; the man with no imagination may collect facts, but he cannot make great discoveries.
I would designate as science fiction in the best sense: they are visions and anticipations by which we seek to attain a true knowledge, but, in fact, they are only imaginations whereby we seek to draw near to the reality.
When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There's something that might be called the 'graduate student syndrome'; graduate students hardly believe they can make a discovery.
Because a fact seems strange to you, you conclude that it is not one. ... All science, however, commences by being strange. Science is successive. It goes from one wonder to another. It mounts by a ladder. The science of to-day would seem extravagant to the science of a former time. Ptolemy would believe Newton mad.
At the heart of science is an essential balance between two seemingly contradictory attitudes-an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense.
