Edward Victor Appleton: Pioneer in Ionospheric Physics and Nobel Laureate
Edward Victor Appleton (6 September 1892 – 21 April 1965) was an English physicist. In 1947, Edward Victor Appleton was awarded the Nobel Prize in Physics.
Life and Career
Edward Victor Appleton was born on 6 September 1892, in Bradford, England. Appleton studied at St. John’s College, Cambridge, where he initially focused on engineering but later shifted to physics. He conducted research on radio waves’ behavior in the upper atmosphere, particularly on the phenomenon of radio wave reflection by the ionized layers of the ionosphere. In 1924, he successfully demonstrated the existence of the ionosphere’s F-layer, which was responsible for the reflection of radio waves around the Earth’s curvature. This discovery led to advancements in long-distance radio communication.
Appleton was appointed as the Wheatstone Professor of Physics at the University of London in 1926 and continued his research on the ionosphere. His work was crucial during World War II, as it aided in the development of radar systems and communication techniques. Edward Victor Appleton passed away on 21 April 1965, in Edinburgh, Scotland.
Award and Legacy
Edward Victor Appleton was awarded the Nobel Prize in Physics in 1947 for his pivotal contributions to the understanding of the ionosphere’s properties and the reflection of radio waves from its layers. Appleton’s research significantly advanced our understanding of the ionosphere’s role in radio communication and its practical applications. His work laid the foundation for the development of various technologies, including radar systems, long-distance radio communication, and satellite communication.
His legacy continues through the Appleton Prize, which is awarded by the Institute of Physics in the UK for outstanding contributions to the field of environmental, Earth, or atmospheric physics.
