Who Discovered Half-Life? Exploring Ernest Rutherford's Pivotal Contribution
Discover how Ernest Rutherford uncovered the concept of half-life and its impact on radioactivity.
Video transcript
Ernest Rutherford discovered the concept of half-life. He described how radioactive materials decay over time, with each element having a specific half-life, the period it takes for half of the substance to decay. This breakthrough was pivotal in advancing our understanding of radioactivity and nuclear physics.
