At the end of the 19th century, physicists were finally beginning to understand the nature of matter itself, including the discovery of electrons – tiny particles of negative charge that surround the nucleus. Here’s how J.J. Thompson separated the electrons from their atoms and uncovered their nature. Download the show [MP3] | Jump to Shownotes […]
