Marie Curie

"One never notices what has been done; one can only see what remains to be done."

"I have no dress except the one I wear every day. If you are going to be kind enough to give me one, please let it be practical and dark so that I can put it on afterwards to go to the laboratory."

"Be less curious about people and more curious about ideas."

"Humanity needs practical men, who get the most out of their work, and, without forgetting the general good, safeguard their own interests. But humanity also needs dreamers, for whom the disinterested development of an enterprise is so captivating that it becomes impossible for them to devote their care to their own material profit. Without doubt, these dreamers do not deserve wealth, because they do not desire it. Even so, a well-organized society should assure to such workers the efficient means of accomplishing their task, in a life freed from material care and freely consecrated to research."

"We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for humanity."

"You cannot hope to build a better world without improving the individuals. To that end each of us must work for his own improvement, and at the same time share a general responsibility for all humanity, our particular duty being to aid those to whom we think we can be most useful."

"I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale. We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery also has its beauty. Neither do I believe that the spirit of adventure runs any risk of disappearing in our world. If I see anything vital around me, it is precisely that spirit of adventure, which seems indestructible and is akin to curiosity."

"Although born in a strongly Catholic country, at the age of 17 Marie Curie rejected all forms of religion, professing atheism and placing her trust solely in Enlightenment rationality and progress. She therefore adhered to Positivism, which became her mindset and guided her every action. Feminism found in her an icon of redemption and emancipation. Suffice it to say that in 1885, she went to the employment office to look for work, due to the financial difficulties her family was experiencing at the time, and found a job as a governess."

"The chief difficulty lay in the fact that pitchblende is a very complex mineral and contains in varying quantities nearly all the known metals. ...The analysis of pitchblende by chemical methods, using the procedure sketched above, led to the discovery of two very active bodies, polonium and radium. The name polonium was given to the first substance discovered by Mme Curie in honor of the country of her birth. The name radium was a very happy inspiration of the discoverers, for this substance in the pure state possesses the property of radio-activity to an astonishing degree."

"Life is not easy for any of us. But what of that? We must have perseverance and above all confidence in ourselves. We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained."

"All my life through, the new sights of Nature made me rejoice like a child."

"I believe international work is a heavy task, but that it is nevertheless indispensable to go through an apprenticeship in it, at the cost of many efforts and also of a real spirit of sacrifice: however imperfect it may be, the work of Geneva has a grandeur that deserves our support."
