On the physical meaning of Fermi coordinates
Fermi coordinates (FC) are supposed to be the natural extension of Cartesian coordinates for an arbitrary moving observer in curved space-time. Since their construction cannot be done on the whole space and even not in the whole past of the observer we examine which construction principles are responsible for this effect and how they may be modified. One proposal for a modification is made and ...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولGeneral Transformation Formulas for Fermi-Walker Coordinates
We calculate the transformation and inverse transformation, in the form of Taylor expansions, from arbitrary coordinates to Fermi-Walker coordinates in tubular neighborhoods of arbitrary timelike paths for general spacetimes. Explicit formulas for coefficients and the Jacobian matrix are given.
متن کاملPhysical Instances of Noncommuting Coordinates
Noncommuting spatial coordinates and fields can be realized in actual physical situations. Plane wave solutions to noncommuting photodynamics exhibit violaton of Lorentz invariance (special relativity).

متن کاملThe Social Meaning of Physical Action
Intelligent systems should be able to initiate and understand social interactions, which are always brought about by physical actions. Thus, all physical actions need to be interpreted for their social effects. This paper gives an analytical framework that identifies the main challenges in modelling social interactions. Such interpretation is subjective and might lead to misunderstandings betwe...
