I link from keplero I link with pleasure, a beautiful study published on arxiv.org, developed by a class of the Liceo Scientifico “A. Vallisneri” in Lucca.
Armed with a mp3 with the conversations of Neil armstrong with Houston, thanks to the echo leading and with the help of the software audacity, these students have succeeded in establishing the distance of the earth from the moon, by calculating it in around 3.93 x 10^8 mt. Not to bad for an Italian school, that seems more and more ruined in the national newscasts. This study could have been the proof of the fact that we have really gone to the moon, if we don’t hypothesize a plot that an echo of artificial return has been created for this purpurse….
Finally standing ovation for the researcher Luca Girlanda (perhaps precarious) at 1000 €/month that conducted the study, go on we are with you…
