reply of a great teacher

March 25, 2009

Yesterday I post about the work of  Girlanda about measuring the distante earth-moon by analysing the Armstrong’s. I write him and he’s the reply which underline Luca’s personality best.

Hi zero,
thanks for the pingback I’ve never expect so much rumors.
It was a funny job of some years ago it will apper soon on American Journal of Physics.
If teaching woudn’t be so funny, the money the would count a little bit more




beautifull italian study

March 24, 2009

I link from  keplero I link with pleasure, a beautiful study published on, 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…
