An interpretation of special relativity is presented with alternative principles that treat an appearance of simultaneity as physically real. This implies instantaneous propagation of incoming light, but maintains light’s invariable propagation rate of c by using an alternative measure of speed. The relativistic Doppler effect is derived from physical principles based on the direct appearance o...

This article presents a reflection about care, self-care and caring for oneself and establishes these issues' relations with the paradigms of totality and simultaneity. On the first part of the text, care and its general aspects are contextualized; the second part discusses about care in Martin Heidegger's philosophical perspective; the third part explores self-care on Dorothea Orem's conceptio...

Given two observers, we define the “relative velocity” of one observer with respect to the other in four different ways. All four definitions are given intrinsically, i.e. independently of any reference system. Two of them are given in the framework of spacelike simultaneity and, analogously, the other two are given in the framework of observed (lightlike) simultaneity. Properties and physical ...

Abstract. Photon coincidence spectroscopy is a promising technique for probing the nonlinear regime of cavity quantum electrodynamics in the optical domain, however its accuracy is mitigated by two factors: higher–order photon correlations, which contribute to an enhanced pair count rate, and non–simultaneity of emitted photon pairs from the optical cavity. We show that the technique of photon ...

Studies on human recalibration of perceived visuo-motor simultaneity so far have been limited to the study of recalibration to movement-lead temporal discrepancies (visual lags). We studied adaptation to both vision-lead and movement-lead discrepancies, to test for differences between these conditions, as a leading visual stimulus violates the underlying cause-effect structure. To this end, we ...

Six stable dimer models for 7-azaindole (including the classic C(2h) doubly hydrogen-bonded, coplanar, centrosymmetric dimer) are considered to be observable in adiabatic nozzle jet molecular beams. They are analyzed by hybrid density functional theory (DFT), the MP2 ab initio method for the ground electronic state, and the single-excitation configuration interaction (CIS) (over frozen ground s...
