PLEASE NOTE: Both the Mathcad (MCD) and Adobe (PDF) versions of the paper, "Photon/Atomic/Electrogravitational Energy Master Equation", are included here for downloading. I suggest using Netscape for downloading or reading online. The Mathcad version will allow for experimenting with various values of atomic shell parameters to see exactly what the equation outputs are. The two download file names related to the above paper are: EGPhoton.MCD and EGPhoton.PDF and both may be read using software readers obtainable on the main page of: http://www.electrogravity.com. Included for download Is EGChapt07 in PDF format from my book, "Electrogravitation As A Unified Field Theory", which serves as a convenient reference for the source of the Master Equation presented in the above paper. A Windows format BMP file SW1 is supplied in case the text drawing of the electrogravitational propulsion UFO style craft is not rendered clearly. Also included is a spectrum chart file, Spectrum.jpg, for comparing the outputs of the Master Equation with actual measured spectra of the elements. This is copied from the frequency spectrum chart published by the Exploritorium in San Francisco, California and is meant to be used only with the paper as presented here.
