Electromagnetic energy is a fundamental part of our universe. Humans discovered ways to use this energy for many purposes. From radio to TV, smartphones to Wifi. But electromagnetic energy also influenced another major sector: military operations. Along came the Crows, people who learned electromagnetic energy, applied it to military combat operations, and forever impacted modern warfare. Today, we begin the story of how the greatest scientific minds came to understand this natural phenomenon, how it changed the way we think, live and communicate, and how now electromagnetic spectrum operations, or EMSO, have influenced every major military campaign over the past 100 years. This episode takes you to the scientific roots of EMSO. We hear insights from Mr. Charles “Chuck” Quintero from the Johns Hopkins University of Applied Physics Laboratory, who discusses the evolution of natural philosophy from Sir Isaac Newton to James Clerk Maxwell to Heinrich Hertz. He tells the stories behind the great minds of scientists, physicists, and mathematicians and how they contributed to Maxwell’s theories on electromagnetism and the impact it later had on the world of EMSO.
