Making Waves




The first public demonstration of electromagnetic waves

During the 1894 British Association meeting in Oxford, Oliver Lodge was lecturing on light and the way in which it is perceived by the brain. On 14th August he set up a demonstration in which a morse key activated a transmission that was received in an adjacent room and caused the deflection of a spot of light. This was in effect the first public demonstration of wireless, but no-one saw any practical application for the phenomenon, and it passed without note.


Marconi on the job

Marconi, however, who had almost no formal scientific education, worked round the clock to develop a commercial communication system. The British GPO were only mildly impressed, and failed to see the possibilities of a popular entertainment system based on radio. Similarly, the experts mocked Marconi's plans for transatlantic communication: they knew that the curvature of the earth would defeat him, and that his straight-line signals would simply head out into space!


The first hackers?

At an early Marconi radio demonstration, a rival group set up nearby and transmitted a jamming signal so as to disrupt the proceedings.
