Burke traces technological change in warfare, electricity, and magnetism to the development of radar, radio, and deep-space telecommunications
Third in a series combining history and science to discover why major technological changes occurred and traces these inventions to seemingly unrelated "triggers" during the past 12,000 years. This segment shows a link between the telephone and riding stirrups. When the Normans first used stirrups, their advantage caused every army to search for money to re-outfit. They dug mine shafts deeper, the shafts began to flood, and scientists like Galileo investigated vacuums and air pressure to bring the mines back to working order. These studies formed the foundations for radio, telephones, and deep space telecommunications that may someday contact other worlds
