Physicist Suzie Sheehy brings to life one of science's most pivotal moments by replicating J.J. Thomson's groundbreaking experiment that revealed the electron.
This demonstration, conducted with simple tools, vividly shows how atoms, once thought to be indivisible, are actually composed of smaller, fundamental particles. Thomson's discovery of the electron in 1897 fundamentally altered our understanding of matter and paved the way for modern physics.
Sheehy's recreation makes this complex scientific history accessible and engaging, highlighting the power of direct observation and experimentation in scientific advancement. The experiment visually proves the existence of negatively charged particles within the atom, a concept that revolutionized scientific thought and led to further exploration of atomic structure.
