fangfufu [The first international radiotelegraph]
@@ Line 20: / Line 20: @@
 The first international radiotelegraph transmission was conducted by Marconi and his assistant on 27-Mar-1899, between Wimereux France and the Upper Lighthouse. This time round, Marconi chose to go to Wimereux, and left his assistant at the Upper Lighthouse. The tour guide found this funny. The tour guide said Wimereux has good food and beautiful women. I think this shows that Marconi is a true scientist – he always picked the most arduous duty.
-The first message radio message sent internationally was “Greetings from France to England through the ether.” [(http://news.bbc.co.uk/1/hi/entertainment/304466.stm)] The tour guide mentioned that these days people do not use the word “ether” any more, people prefer the word “airwave”. I believe the word “ether” might have deeper meaning. Michelson-Morley Experiment was performed in 1887. Special Relativity was formulated by Einstein in 1905. Therefore, it might be plausible that Marconi believed light travelled through aether.
