Quote by Frederic Joliot-Curie

“Some months ago we discovered that certain light elements emit positrons under the action of alpha particles. Our latest experiments have shown a very striking fact: when an aluminium foil is irradiated on a polonium preparation [alpha ray emitter], the emission of positrons does not cease immediately when the active preparation is removed: the foil remains radioactive and the emission of radiation decays exponentially as for an ordinary radio-element. We observed the same phenomenon with boron and magnesium.”

“That no generally applicable law of the formulation and development of hybrids has yet been successfully formulated can hardly astonish anyone who is acquainted with the extent of the task and who can appreciate the difficulties with which experiments of this kind have to contend.”

“The investigation of causal relations between economic phenomena presents many problems of peculiar difficulty, and offers many opportunities for fallacious conclusions. Since the statistician can seldom or never make experiments for himself, he has to accept the data of daily experience, and discuss as best he can the relations of a whole group of changes; he cannot, like the physicist, narrow down the issue to the effect of one variation at a time. The problems of statistics are in this sense far more complex than the problems of physics.”

“The physicist can never subject an isolated hypothesis to experimental test, but only a whole group of hypotheses.”

“The shell model, although proposed by theoreticians, really corresponds to the experimentalist's approach. It was born from a thorough study of the experimental data, plotting them in different ways, and looking for interconnections.”

“[Pitchblende] consists of a peculiar, distinct, metallic substance. Therefore its former denominations, Pechblende, pitch-iron-ore, &c. are no longer applicable, and must be supplied by another more appropriate name. I have chosen that of Uranium, as a kind of memorial, that the chemical discovery of this new metal happened in the period of astronomical discovery of the new planet Uranus.”
