Marie Curie’s famous sayings are as follows:

1. Science itself has great beauty. A research scientist is not only a technician but also a child. In the natural scenery, he seems obsessed with mythological stories.

2. The world invisible to human beings is not a phantom of fantasy, but a reality illuminated by the light of science. Dignity is the power of science.

3. I don’t feel sorry for my poor life at all. What makes me sad is that the day is too short and passes so quickly.

4. Scientific discussion and research itself contains the most beautiful, and the happiness it brings to people is the reward; so I find happiness in my work.

5. What is important in science is what is researched, not the individual researcher.

6. Curiosity is the first virtue of scholars.

7. If you can live following your ideals, act with a spirit of integrity and freedom, perseverance to move forward, and thoughts that are honest and not self-deceptive, you will surely reach the state of perfection.

8. Those who work for public happiness, no matter which department they are in, cannot be separated by national borders. The fruits of their labor belong not only to a country, but to the entire human race.

9. The motherland is more important than life. It is our mother and our land.

10. The weak wait for opportunities, while the strong create opportunities.

11. No matter how proud a person is of his achievements, he should drink water and think about the source. He should remember that his teacher sowed the first seeds of their growth.

12. I have never been lucky, and I will never expect to be lucky in the future. My highest principle is to never give in to any difficulty.

13. I use your bonus as a kind of honor loan, which helped me obtain preliminary honors. The loan should be returned, please send it to other Polish youth determined to live in poverty for greater honor.

14. I know that life is short and fragile. I knew it couldn't leave anything behind. I know others see it differently and I can't guarantee that my efforts are justified, but I do it anyway. I do it for no doubt the reason I have to do it, just like a silkworm has to make a cocoon.
