Interpretation

What this quote means

Science focuses on what can be quantified and studied rigorously, while non-empirical pursuits lack scientific merit.

Ernest Rutherford's quote emphasizes the importance of measurement and empirical evidence in the field of science. He argues that true scientific inquiry is grounded in the ability to measure and quantify phenomena, contrasting it with mere collection of data or observations, which he dismisses as akin to 'stamp collecting', a term that implies a lack of scientific depth or understanding.

The energy produced by the breaking down of the atom is a very poor kind of thing. Anyone who expects a source of power from the transformation of these atoms is talking moonshine.

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.
