Marie studied Physic and Maths and got her Master's degree in both subjects. When she graduated from university, she started research for magnetism. It was at that time she met Pierre Curie, a young scientist. They fell in love immediately and got married. Marie moved to his house and they both started examining uranium and other elements to decide whether they were radioactive. It took them four years to isolate the radioactive source which she named radium. For this, they gained a Nobel Prize in Physics in 1903.
