Good luck, Pierre!
I guess the organizers (Les Amis de la Radiesthésie) enjoyed the conference since they invited me to be the speaker of the conference they will organize in September in Southern France (Var). They also recommended me to another organization for which I will intervene during a conference in July in Western France.
I think it went well, but I'm judge and jury here. Maybe the forum members that attended the conference will share their feedbacks.
Personally, I have a question for you Pierre: you mention that a brown dwarf cannot be detected by our current telescopes because their radiations are in the very low infrared if a remember well, so my question is: so how do we know that such objects exist? Is it only theoretical objects? I mention it because it struck me during the conference.
