Study Notes
Marie Curie's Early Life and Education
- Born Maria Skłodowska in Warsaw, Poland
- Mother and sister died by the age of ten.
- Women were not allowed to attend college, so she studied secretly while working as a governess
- Saved her earnings to attend college at Sorbonne in Paris
- Met and married physicist Pierre Curie
Marie Curie's Discoveries
- Investigated uranium with Pierre Curie
- Identified two radioactive elements
- Polonium (named after her native country, Poland)
- Radium
- Awarded the 1903 Nobel Prize in Physics with Pierre Curie and Henri Becquerel
Pierre Curie's Contribution
- Pierre was deeply influenced by Marie's work.
- He abandoned his research to support her pursuit.
- Contributed significantly by publishing joint papers with Marie.
Further Contributions
- Isolated radium in 1910 with chemist André-Louis Debierne
- Awarded the 1911 Nobel Prize in Chemistry
- First person to win two Nobel Prizes
Antoine Henri Becquerel
- First to discover natural radioactivity
- In 1896, while investigating X-rays, he discovered uranium emits radioactive particles
- Studied the relationship between phosphorescence and X-rays
- The unit of radioactivity is named after him: the becquerel
The Danger of Radioactivity
- Marie Curie coined the term "radioactivity."
- She was unaware of the dangers and carried and stored radioactive samples in her desk.
- She experienced radiation sickness
- Scientists, including Curie, realized the hazards
- "One never notices what has been done; one can only see what remains to be done." - Marie Curie, 1894
The Curies and Radioactivity
- The Curies believed radiation, if used properly, could be beneficial in medicine and science.
Working to Save Lives
- The Curies believed knowledge should be shared, not profitted from.
- During World War I, Marie Curie funded 20 mobile X-ray units ("Petites Curies") to help wounded soldiers
- She trained others to use the X-rays.
Pioneering Cancer Research
- Curie established the Curie Foundation to research the use of radium for cancer treatment.
- She toured the US twice to raise funds for this research
- She died from aplastic anemia, likely caused by radiation exposure
Marie and Pierre Curie's Collaboration
- They met in Paris and married in 1894
- They collaborated on research into radioactivity
- They were awarded the Nobel Prize in 1903
Marie Curie's Significance
- First woman to win a Nobel Prize
- Donated Nobel medals for World War I effort
- One gram of radium cost $100,000 in 1921.
