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.

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists-whether through design or stupidity, I do not know-as admitting that the fossil record includes no transitional forms. Transitional forms are generally lacking at the species level, but they are abundant between larger groups.
But I don't see myself as a woman in science. I see myself as a scientist.
I call on all scientists in all countries to cease and desist from work creating, developing, improving and manufacturing further nuclear weapons - and, for that matter, other weapons of potential mass destruction such as chemical and biological weapons.
If you're going to go into space, you have to have an objective, a mission. Where do you want to go? Earth orbit? The moon? Mars? What's the technology to get there? You develop the technology for the mission.
This is a basic problem, to feed 6.6 billion people. Without fertilizer, forget it. The game is over.
What the scientists have always found by physical experiment was an a priori orderliness of nature, or Universe always operating at an elegance level that made the discovering scientist's working hypotheses seem crude by comparison. The discovered reality made the scientists exploratory work seem relatively disorderly.
