Study Notes
20th Century Physics Achievements
- The major achievement in physics in the 20th century was the development of quantum mechanics and relativity.
Redefining Physics
- Albert Einstein redefined physics as the study of relations between observers and events.
Impact of X-ray and Radioactivity Discoveries
- The discoveries of X-ray and radioactivity had a significant impact on our understanding of the structure of the atom.
- These discoveries led to the development of the atomic model, where atoms are composed of a nucleus (containing protons and neutrons) surrounded by electrons.
- The discovery of radioactivity by Henri Becquerel in 1896 and the discovery of X-rays by Wilhelm Conrad Röntgen in 1895 challenged the existing understanding of the atomic structure.
- These discoveries paved the way for a deeper understanding of the atomic structure and led to the development of nuclear physics.
