The discovery of radioactivity is the phenomenon where certain elements spontaneously emit radiation in the form of particles or electromagnetic waves. This was first observed by Henri Becquerel in 1896 when he noticed that uranium salts emitted rays that could expose photographic plates. This discovery led to further research by Marie and Pierre Curie, who identified the elements polonium and radium as being radioactive. Radioactivity has since been found to have important applications in medicine, industry, and energy production. **

The discovery of America refers to the arrival of the first European explorers to the continent, particularly Christopher Columbus's voyage in 1492.
