Beginnings of Modern Science: 19th Century
Andre-Marie Ampere confirms the flow of electrical current, leading to the science of electrodynamics
Michael Faraday found the means to generate electricity by moving a conductor through a magnetic field
Jagadis Chandra Bose demonstrated the transmission of electric signals through space; Marconi was awarded a patent for the same achievement a year later
