Doubly Special Relativity: A New Relativity or Not [PDF]

open access: yesAIP Conference Proceedings, 2006
Double Special Relativity theories are the relativistic theories in which the transformations between inertial observers are characterized by two observer-independent scales of the light speed and the Planck length. We study two main examples of these theories and want to show that these theories are not the new theories of relativity, but only are re ...

About the origins of the general theory of relativity: Einstein's search for the truth [PDF]

open access: yes, 2005
On the 20th June 1933 Professor Einstein addressed a large and enthusiastic audience in the Victorian Gothic Bute Hall of the University of Glasgow. Einstein spoke 'About the Origins of the General Theory of Relativity'.

The principle of relativity and the special relativity triple [PDF]

open access: yesPhysics Letters B, 2009
Based on the principle of relativity and the postulate on universal invariant constants ($c,l$) as well as Einstein's isotropy conditions, three kinds of special relativity form a triple with a common Lorentz group as isotropy group under full Umov-Weyl-Fock-Lorentz transformations among inertial motions.

Theory of Gravity Dependent on Entropy

open access: yesReports in Advances of Physical Sciences, 2023
Gravitational redshift decreases the resolution of measurements, causing entropy by increasing the possible microstates of position and momentum for objects within a gravitational field.

Space and time in special relativity [PDF]

open access: yesRevista Brasileira de Ensino de Física
In this review of the kinematic part of Einstein’s Theory of Special Relativity, the physical meaning of the Lorentz Transformations is elucidated from basic physical facts that, although implicit in the formulation of the theory, are usually overlooked ...

Spatial Geometry and Special Relativity: a comparative approach

open access: yesRevista Brasileira de Ensino de Física
In this work, it is shown the interplay of relative and absolute entities, which are present in both spatial geometry and special relativity. In order to strengthen the understanding of special relativity, we discuss firstly an instance of geometry and ...

PHENOMENOLOGY OF DOUBLY SPECIAL RELATIVITY [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
Investigations of the possibility that some novel "quantum" properties of space–time might induce a Planck-scale modification of the energy/momentum dispersion relation focused at first on scenarios with Planck-scale violations of Lorentz symmetry, with an associated reduced n-parameter (n<6) rotation-boost symmetry group.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.
