Do you have a reference to plane polarized photons having a spin? My investigations suggest that all photons emitted from electrons changing “orbitals” are circularly polarized. These are the X-rays, visible and IR. Photons emitted from antennae, radio waves etc, are plane polarized. </div><div><br></div><div>Experiments done on photon spins are the former variety. I have not seen references to using photons that have passed through plane polarizing filters for such measurements. It is something that can be tested experimentally. There may be some interpretation issues associated with such measurement that make it not such a straight forward experiment. </div><div><br></div><div>Cheers,</div><div><br></div><div>Vivian Robinson<br> <div id="bloop_sign_1502574682663186944" class="bloop_sign"></div> <br><p class="airmail_on">On 10 August 2017 at 12:34:25 AM, Chip Akins (<a href="mailto:chipakins@gmail.com">chipakins@gmail.com</a>) wrote:</p> <blockquote type="cite" class="clean_bq"><span><div lang="EN-US" link="blue" vlink="purple"><div></div><div><!--[if !mso]><![endif]--><!--[if gte mso 9]><xml>

Opinions are expressed and bounced between participants. I have tried to suggest the best or scientific method is to state the physics behind the theory or effect to be conveyed. Then use mathematics to determine the magnitude of that effect. If there is a match between the calculated and observed effects, there is some support for the theory proposed. <o:p></o:p></span></p></div><div id="bloop_customfont"><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">To this end I append a link to an earlier presentation of my idea of what constitutes photons. It is an oscillation of electric and magnetic fields in the electric permittivity and magnetic permeability of free space respectively. Their oscillatory nature gives them wave properties. Their limited extent gives them particle properties. <o:p></o:p></span></p></div><div id="bloop_customfont"><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">IMHO their lateral extent allows diffraction and single photon interference. I suggest but haven’t shown that entangled photons would have the same phase and could allow dual and even multiple photon interference. I make other suggestions it it as well. This includes the origins of their mass and spin as angular momentum. Circularly polarized photons will have angular momentum (spin) of hbar. Linearly polarized photons will not. Other spins are possible.<o:p></o:p></span></p></div><div id="bloop_customfont"><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif"><o:p> </o:p></span></p></div><div id="bloop_customfont"><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Helvetica",sans-serif">This was forwarded for discussion.
