By reorganizing the Lense-Thirring spacetime metric of linearized general relativity, we have determined the appropriate field potential four-vector and the field strength tensor which generates dynamics in the GEM field. The general covariant equation of motion of the spin four-vector of a gyroscope driven by the GEM field strength tensor provides the expected form of the frame-dragging and geodetic effects after introducing a gyromagnetic ratio η = 4 as an internal dynamical property of the gyroscope.","PeriodicalId":470553,"journal":{"name":"European journal of applied physic","volume":"69 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135167428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The situation became more complicated after the experiments of Land who documented that the classical color theory (= colors correspond to exact wavelength of light) is valid completely in the dark surroundings only. We are at the crossroads to find the boundary between the physical properties of colors and the perception of those photons in the retina and the brain. Therefore, the more general physical color theory should interpret those color effects where the classical physical color theory fails. As a potential candidate we present the overlooked Descartes´ color theory based on the rotation energy of visible, ultraviolet, and infrared photons. The rotation energy of colors was defined as E = hν570*(λx/λ570) where index describes the wavelength of photons in nanometers. This new mathematical description of colors enables to newly interpret situations where the average rotation energy of all reflected photons determines the color impression. The colors formed behind the triangular prism could be interpreted as the lateral diffusion of the rotation energy of ultraviolet and infrared photons (= called by Old Masters as the interplay of darkness with the light) through the field of refracted visible photons and with the modification of their rotation energy. The white color can be interpreted as the constructive interference of red, green, and blue colors with the constructive angle cos (120°) = -0,5. The black color can be interpreted as the destructive interference of cyan, magenta, and yellow colors with the destructive angle cos (180°) = -1. For the case of illumination with a range of wavelengths the resulting color is determined from the average rotation energy of all reflected photons – a model for the interpretation of the color constancy.","PeriodicalId":470553,"journal":{"name":"European journal of applied physic","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135889468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At various perturbed order parameters, it is discovered that the nature rapidly decreases with distance from the Bohr’s radius. Additionally, the nature with perturbed order parameters was discovered to be linear at various separations beyond Bohr’s radius. This demonstrates that while a large amount of energy is needed to perturbed a system close to the Bohr’s radius, very little energy is needed to perturbed a system farther away from the Bohr’s radius.","PeriodicalId":470553,"journal":{"name":"European journal of applied physic","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136180911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
