When a constant electric current flows along a cylindrical wire, its strength is the same at every part of the section of the wire.
German physicist (1857–1894)
He proved that invisible waves could travel through empty space — the experiment that turned Maxwell's equations from theory into the foundation of every wireless technology we use.
Heinrich Rudolf Hertz was born in Hamburg on 22 February 1857. A physicist working in Germany, he set out to test James Clerk Maxwell's mathematical predictions about electromagnetism — predictions that remained unproven and contested. In a series of careful experiments, Hertz became the first to conclusively demonstrate that electromagnetic waves existed and behaved exactly as Maxwell's equations described. The work opened the door to radio, radar, and every form of wireless communication that followed. He died on 1 January 1894, at thirty-six.
