Italian nationalism in the sciences fascinates me.

The final results of this experiment were publicly demonstrated on 24 June 2011 on Piazza San Marco, Venice, in the presence of the international press, experts, well-known personalities and the general public. In the style of Guglielmo Marconi, we realized this first public demonstration of radio vortices by also involving ordinary people in the experiment—a different way to communicate science. A light and sound show with projections onto the fa¸cade of Palazzo Ducale explained to the audience what the experimenters were doing. More than 2000 people attended the ‘live’ experiment at 21:30 local time and when the signal was tuned from vorticity zero to vorticity one at the same frequency and transmitting simultaneously, a rifle shot was heard, in honour of the first radio transmission made by Guglielmo Marconi in 1895. After this, on the facade of Palazzo Ducale the words ‘segnale ricevuto’, which in Italian means ‘signal received’, were projected.
