What did Edward Victor Appleton blue plaque do at King's College London?

The Story

# Edward Victor Appleton at King's College London Standing before this blue plaque on the Strand, you're positioned at the very epicenter where Edward Victor Appleton revolutionized our understanding of the invisible realm above Earth. From 1924 onwards, working within these walls at King's College London, Appleton conducted the groundbreaking experiments that revealed the existence and behavior of the ionosphere—that electrically charged layer of atmosphere that bounces radio waves around the globe. Using ingeniously simple equipment, he sent radio signals skyward and measured how they returned, proving that a reflecting layer existed in the upper atmosphere, a discovery that transformed both radio communication and our fundamental grasp of planetary physics. This modest London address became the birthplace of the science that would eventually earn him the Nobel Prize in Physics in 1947, making King's College not merely an institution where he worked, but the historic laboratory where modern radio science itself was born.
