Death ray: History, Art, Measurement & Science
The death ray or death beam is a theoretical particle beam or electromagnetic weapon first theorized around the 1920s and 1930s. Around that time, inventors such as Guglielmo Marconi, Nikola Tesla, Harry Grindell Matthews, Edwin R. Scott, Erich Graichen and others claimed to have invented it independently. In 1957, the National Inventors Council was…

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Death ray, one of the stronger structural bridges in this analysis connects Death ray with History. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
