The inclusion of a solid solute that yields a positive excess enthalpy of solution with the R14 creates a potential for complete exhaust heat regeneration. The solution\u0000 reaction provides a temporary thermal reservoir for the cycle's low temperature exhaust heat until that energy is regenerated as heat by retrograde solubility during the cycle's high temperature and low density expansion phase. A slow solute dissolution rate in the solvent's low density state\u0000 near the cycle's high temperature enables the cycle to utilize all of the regenerated exhaust heat either as work output or by exhausting surplus heat at a second temperature level. The cycle's thermodynamic path establishes solvent property reference points that can be used to determine the\u0000 maximum positive excess enthalpies of solution required for a solvent to accomplish total exhaust heat regeneration when used as the cycle's working fluid.","PeriodicalId":51274,"journal":{"name":"Physics Essays","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43319322","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}

Einstein never discussed the relation between these\u0000 two definitions. Neither has anyone else, to my knowledge. I show that these definitions are not equivalent because they have different scopes of applicability, but that they are equivalent wherever both apply. My proof of this partial equivalence is a corollary of my proof that both of Einstein’s\u0000 definitions clash with the natural ticking of monochromatic light, which I call an electromagnetic wave clock. Einstein disparaged the idea of absolute simultaneity, but the reasons he gave were not good ones. He suggested that the idea originated in a confusion between happening simultaneously\u0000 and being seen simultaneously. This thesis is dubious. It is also irrelevant, because an idea that originates in a confusion need not be a confused idea. He suggested that there could be no experimental test for absolute simultaneity. I refute this suggestion by describing an experimental\u0000 test for absolute simultaneity, which I call the melt-mark test. The empirical credentials of Einstein’s definitions are not superior to those of absolute simultaneity. Einstein writes as if he can banish the idea of absolute “simultaneity” by merely giving the word “simultaneity”\u0000 a new meaning. But many words have multiple meanings; Einstein merely made simultaneity such a word. The meanings of “simultaneity” that there is reason to disparage are Einstein’s definitions, because they clash with the electromagnetic wave clock. None of these points is\u0000 properly appreciated by today’s physics community, where Einstein’s assertions about simultaneity continue to enjoy broad acclaim. Physical theories that employ the idea of absolute simultaneity are often wrongly rejected because they do.","PeriodicalId":51274,"journal":{"name":"Physics Essays","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42093170","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}

Second, the speed of light propagation in vacuum is constant relative to the absolute reference system of vacuum. Third, the speed of light propagation in the medium remains constant relative to the inertial frame of the medium.\u0000 Based on this, we have successfully explained the phenomenon of Michelson‐Morley experiment, Fizeau experiment, and light aberration phenomenon that have long troubled the academic community. Finally, we prove that the two basic assumptions on which special relativity is based are wrong,\u0000 so the Lorentz transformation and its series of inferences, as the core content of special relativity, are not tenable.","PeriodicalId":51274,"journal":{"name":"Physics Essays","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44209117","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}

More than one NKE particles can make up a stable\u0000 system by means of interactions between them and such a system has necessarily negative temperature. Thus, many-body theories for NKE systems are desirable. In this work, the many-body theories for NKE systems are presented. They are Thomas‐Fermi method, Hohenberg‐Kohn theorem,\u0000 Khon‐Sham self-consistent equations, and Hartree‐Fock self-consistent equations. They are established imitating the theories for PKE systems. In each theory, the formalism of both zero temperature and finite negative temperature is given. In order to verify that tunneling electrons\u0000 are of NKE and real momentum, an experiment scenario is suggested that lets PKE electrons collide with tunneling electrons.","PeriodicalId":51274,"journal":{"name":"Physics Essays","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42600054","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}

This is to be viewed in the context of the stated position in physics that synchronization of spatially separated clocks in any inertial frame depended on the adoption of a\u0000 convention for its resolution. The preferred method of synchronization of spatially separated clocks is the standard convention recommended by the theory of relativity; however, it still remains a convention.","PeriodicalId":51274,"journal":{"name":"Physics Essays","volume":" ","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47901920","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}

To forecast the expansion time of the bubble\u0000 under irradiated shock waves, we primarily relied on Schwinger calculations. Furthermore, we addressed the inconsistencies associated with the failure to link sonoluminescence (SL) with the Casimir effect. Our findings indicate that SL is a highly delicate and reliant metric, with its measurement\u0000 relying on variables such as the type of gas used to produce the bubble, fluid and gas temperatures, surface tension, density, pressure, and radius. Based on our analysis, we conclude by proposing adjustments to various gases, particularly at different temperatures, to accurately assess SL\u0000 using Casimir forces and energy.

The standard model bases its arguments on the wave function and its subsequent collapse. The sum-over-paths model is equivalent to the standard model, but it explains interference by avoiding use of the wave function and its conceptual problems due to collapse.
