⌘Heinrich Hertz - The electromagnectic wave
Hertz did not realise the practical importance of his experiments. He stated that, "It's of no use whatsoever[...] this is just an experiment that proves Maestro Maxwell was right - we just have these mysterious electromagnetic waves that we cannot see with the naked eye. But they are there." [3]
Asked about the ramifications of his discoveries, Hertz replied, "Nothing, I guess." [3]
Note
The relation between the electrical and the magnetic component of the electromagnetic wave was probably the most important discovery of Heinrich Hertz.
⌘The real researchers
Guglielmo Marconi (1874 - 1937) experimented with Hertz waves in 1894/1895
- used 50000 UK pound on a transatlantic experiment in 1901
- brought electromagnetics to life

⌘The real researchers - Graham Bell
- Graham Bell (1874 -1922) invented the phone,...
- but who invented also the mobile phone back in 1924?
Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study
