If you are aware of an interesting new academic paper (that has been published in a peer-reviewed journal or has appeared on the arXiv), a conference talk (at an official professional scientific meeting), an external blog post (by a professional scientist) or a news item (in the mainstream news media), which you think might make an interesting topic for an FQXi blog post, then please contact us at forums@fqxi.org with a link to the original source and a sentence about why you think that the work is worthy of discussion. Please note that we receive many such suggestions and while we endeavour to respond to them, we may not be able to reply to all suggestions.

Please also note that we do not accept unsolicited posts and we cannot review, or open new threads for, unsolicited articles or papers. Requests to review or post such materials will not be answered. If you have your own novel physics theory or model, which you would like to post for further discussion among then FQXi community, then please add them directly to the "Alternative Models of Reality" thread, or to the "Alternative Models of Cosmology" thread. Thank you.

Essay Abstract

The matter field can be naturally eliminated from the equations of the Klein-Gordon-Maxwell electrodynamics in the unitary gauge. The resulting equations describe independent dynamics of the electromagnetic field in the following sense: if components of the 4-potential of the electromagnetic field and their first derivatives with respect to time are known in the entire space at some time point, the values of their second derivatives with respect to time can be calculated for the same time point, so the Cauchy problem can be posed, and integration yields the 4-potential in the entire space-time. This surprising result both permits mathematical simplification, as the number of fields is reduced, and can be useful for interpretation of quantum theory. For example, in the Bohm interpretation, the electromagnetic field can replace the wave function as the guiding field. Independent of the interpretation, quantum phenomena can be described in terms of electromagnetic field only. A generalized Carleman linearization procedure generates for the system of nonlinear partial differential equations of the Klein-Gordon Maxwell electrodynamics a system of linear equations in the Hilbert space, which looks like a second-quantized theory and is equivalent to the original nonlinear system on the set of solutions of the latter. Similar, but less general results are obtained for the Dirac-Maxwell electrodynamics.

Andrey

An impressive essay that shows that there is much we don't understand in the accepted science we think everyone understands.

In fact you write "it was not noticed THEN or LATER that the equations of Schroedinger's work share another unique and important feature of "new electrodynamics". This a perfect example of what I call the "regressive"method. Nearly everyone is charging ahead using the latest new maths or crazy physical idea. That is the progressive route. It assumes the science we have is perfect. Your essay demonstrates it has significant imperfections.

In my essay I argue that the first step in reaching the ultimate limits of physics must be regressive. We must first ensure that the existing foundations are sound and adequate, before charging ahead with Bits of String.

Pada Bayi di bawah usia 1 bulan atau Neonatus

Pada neonatus,Obat Kencing Nanah konjungtivitis bilateral (neonatorum Oftalmia) sering mengikuti persalinan pervaginam dari ibu, yang tidak diobati terinfeksi. Namun, penularan ke bayi juga bisa terjadi pada rahim atau pada periode postpartum.

Gejala konjungtivitis gonokokal termasuk sakit mata, kemerahan, dan keluarnya cairan bernanah. Neonatus juga bisa memperoleh faring, infeksi pernapasan, atau dubur atau disebarluaskan infeksi gonokokal (DGI).Obat Kencing Nanah Di ApotikOrganisme ini bisa menyebabkan cedera permanen pada mata sangat cepat. Pengakuan yang cepat dan pengobatan adalah penting untuk menghindari kebutaan.

Kebutaan akibat infeksi gonokokal neonatal adalah masalah serius di negara berkembang tetapi sekarang jarang di Amerika Serikat dan di negara-negara lain di mana profilaksis konjungtiva bayi dengan terapiOBAT KENCING NANAH HERBAL antimikroba adalah rutin. Namun demikian, bayi dari ibu dengan infeksi yang tidak diobati, perawatan sebelum melahirkan miskin, dan kelahiran dimonitor terus beresiko.Infeksi langsung dengan N gonorrhoeae pada neonatus juga dapat terjadi melalui kulit kepala di lokasi elektroda pemantauan janin.
