From Galileo to Poldhu and Beyond

October 19th-20th, 2009

On the occasion of the IX edition of the “Italian Language in the World Week”, the Italian Cultural Institute, in collaboration with the University of Western Ontario has presented the conference

Science of the universe on the centenary of Guglielmo Marconi’s Nobel Prize award
 by Prof. Francesco Paresce (National Institute of Astrophysics - Bologna)
Monday October 19th at the Italian Cultural Institute - Toronto
Tuesday October 20th at the University of Western Ontario - London, Ontario

The first space physics experiment by means of radio waves was carried out by Guglielmo Marconi in December 1901 by sending a radio signal from Poldhu in Cornwall, England, that was received across the Atlantic Ocean in St. Johns, Newfoundland.

This experiment, deemed impossible by experts of the time, launched the telecommunications industry and proved the existence of the earth’s ionosphere in one fell swoop. Spectacular progress since then in the cost and efficiency of wireless communication has allowed us today to communicate through satellites and space probes all the way to the edge of the solar system and to receive a large amount of extremely significant scientific information about the universe around us.
In his talk, Paresce has briefly summarized the development of research in this area from the first experiments by Marconi for which he was awarded the physics Nobel Prize in 1909 to the fascinating discoveries of modern space science obtained by space probes and satellites like the Hubble Space Telescope.
All this, Paresce has remembered, was made possible by the strong intuition and tenacity of a man determined to communicate without wires throughout space in the best Galilean tradition of continuous attempts (provando e riprovando).
