There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

I was taught that the way of progress was neither swift nor easy.

After all, science is essentially international, and it is only through lack of the historical sense that national qualities have been attributed to it.

I am one of those who think like Nobel, that humanity will draw more good than evil from new discoveries.

I have frequently been questioned, especially by women, of how I could reconcile family life with a scientific career. Well, it has not been easy.

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 must be attained.

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.

A scientist in his laboratory is not a mere technician: he is also a child confronting natural phenomena that impress him as though they were fairy tales.

Be less curious about people and more curious about ideas.

In science, we must be interested in things, not in persons.

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

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

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

All my mind was centered on my studies, which, especially at the beginning, were difficult. In fact, I was insufficiently prepared to follow the physical science course at the Sorbonne, for, despite all my efforts, I had not succeeded in acquiring in Poland a preparation as complete as that of the French students following the same course.

During the course of my research, I had had occasion to examine not only simple compounds, salts and oxides, but also a great number of minerals.

During the year 1894, Pierre Curie wrote me letters that seem to me admirable in their form. No one of them was very long, for he had the habit of concise expression, but all were written in a spirit of sincerity and with an evident anxiety to make the one he desired as a companion know him as he was.

I tried out various experiments described in treatises on physics and chemistry, and the results were sometimes unexpected. At times, I would be encouraged by a little unhoped-for success; at others, I would be in the deepest despair because of accidents and failures resulting from my inexperience.

I was only fifteen when I finished my high-school studies, always having held first rank in my class. The fatigue of growth and study compelled me to take almost a year's rest in the country. I then returned to my father in Warsaw, hoping to teach in the free schools.

In 1903, I finished my doctor's thesis and obtained the degree. At the end of the same year, the Nobel prize was awarded jointly to Becquerel, my husband and me for the discovery of radioactivity and new radioactive elements.

In 1906, just as we were definitely giving up the old shed laboratory where we had been so happy, there came the dreadful catastrophe which took my husband away from me and left me alone to bring up our children and, at the same time, to continue our work of research.

In chemical terms, radium differs little from barium; the salts of these two elements are isomorphic, while those of radium are usually less soluble than the barium salts.

My experiments proved that the radiation of uranium compounds can be measured with precision under determined conditions and that this radiation is an atomic property of the element of uranium.

Pierre Curie came to see me and showed a simple and sincere sympathy with my student life. Soon he caught the habit of speaking to me of his dream of an existence consecrated entirely to scientific research, and he asked me to share that life.

The death of my husband, coming immediately after the general knowledge of the discoveries with which his name is associated, was felt by the public, and especially by the scientific circles, to be a national misfortune.

Unknown in Paris, I was lost in the great city, but the feeling of living there alone, taking care of myself without any aid, did not at all depress me. If sometimes I felt lonesome, my usual state of mind was one of calm and great moral satisfaction.

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.

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.

Nothing in life is to be feared, it is only to be understood. Now is the time to understand more so that we may fear less.

First principle: never to let one’s self be beaten down by persons or by events.

We must believe that we are gifted for something, and that this thing, at whatever cost, must be attained.

Stability can only be attained by inactive matter.

With tens of thousands of patients dying every year from preventable medical errors, it is imperative that we embrace available technologies and drastically improve the way medical records are handled and processed.

All sorts of computer errors are now turning up. You'd be surprised to know the number of doctors who claim they are treating pregnant men.

The man who cannot endure to have his errors and shortcomings brought to the surface and made known, but tries to hide them, is unfit to walk the highway of truth.

Confession of errors is like a broom which sweeps away the dirt and leaves the surface brighter and clearer. I feel stronger for confession.

Indubitably, magic is one of the subtlest and most difficult of the sciences and arts. There is more opportunity for errors of comprehension, judgment and practice than in any other branch of physics.

Conscience is the mirror of our souls, which represents the errors of our lives in their full shape.

Whatever failures I have known, whatever errors I have committed, whatever follies I have witnessed in private and public life have been the consequence of action without thought.

Therefore let men withdraw themselves from errors; and laying aside corrupt superstitions, let them acknowledge their Father and Lord, whose excellence cannot be estimated, nor His greatness perceived, nor His beginning comprehended.

Irrationally held truths may be more harmful than reasoned errors.
