MARIE CURIE AND THE DISCOVERY OF RADIUM

1.Marie Curie was born in Warsaw on November 7, 1867.

2.Her father was a teacher of science and mathematics in a school, and it was from him that little Marie Sklodowska (her Polish name) learned her first lesson in science.

3.In 1891 she went to Paris to continue her studies at the Sorbonne.

4.She worked for two Master's degrees - one in physics, the other in mathematics.

5.Among many scientists with whom Marie met and worked in Paris was Pierre Curie.

6.When he met Marie he was famous throughout Europe for his discoveries in magnetism.

7.Soon they married.

8.By that time Marie had already had her Master's degree in physics and mathematics and wished to obtain a Doctor's degree.

9.Marie Curie examined every known chemical substance.

10.She repeated her experiments again and again and found that one mineral emitted much more powerful rays than uranium discovered by the French scientist Becquerel.

11.So she could only decide that this mineral must have contained a new element.

12.This seemed unthinkable.

13.Scientists declared that every element had already been known to them.

14. However, all Marie's experiments proved that the mineral contained some new and unknown element.

15. There was no other explanation for the powerful rays, which it emitted.

1.Scientists called the property giving out such rays " radioactivity" and Marie Curie decided to call the new element " radium".
