Montagnier's "proof" is a questionable paper (that has not his name on it, though) that does "decomposing" on the RNA of the viruses with a mathematical transformation that has no biological sense, and by using "patterns" and "waves" "deduces" that there must be something from HIV.

I've read it. It's embarassing on how bad it is written, and the mental gymnastics it uses to "explain" things.
