Re: [Vo]:New vaporizing effect discovered
Sorry! This is a kidding set of e-mails. Photons did always lead to evaporation of water since the earth is covered by water. Even more surprising is that ice does sublimate just from solar irradiation... So following such hoax science today is standard to diffuse a field by usst claiming something is new. J.W.

Re: [Vo]:New vaporizing effect discovered
Nice to see someone else got around to discovering this effect. I observed this phenomenon 15 or 20 years ago, using a 532 nm laser. As these dorks will finally get around to discovering, this effect varies greatly with the refractive index of the material and the degree of polarity. Nitromethane has a very strong response at longer wavelengths. As far as the greatest effect happening at 45 degrees, it's probably really 53 degrees, Brewster's angle for water. As you move the laser across the surface the liquid, you can see a deflection of the reflection following the spot of contact. Easy to do, anyone can do it. I finally gave up long ago, trying to convince credentialed physicists of some of my strange discoveries. Submitting papers to science publications is useless for me, as I discovered decades ago, no credentials. I once had a physicist at UCLA who would agree to put his name on one of my discoveries so it could be published, but he had the bad taste to die on me. I can't be the only one to have discovered this phenomenon long ago, but it's one of those things you sort of think, "So what?"
