In the early 1970s, after a slow start, and lots of hurdles, Quantum Field Theory emerged as the superior doctrine for understanding the interactions between relativistic sub-atomic particles. After the conditions for a relativistic field theoretical model to be renormalizable were established, there were two other developments that quickly accelerated acceptance of this approach: first the Brout-Englert-Higgs mechanism, and then asymptotic freedom. Together, these gave us a complete… 
The Present Situation in Quantum Theory and its Merging with General Relativity
We discuss the problems of quantum theory (QT) complicating its merging with general relativity (GR). QT is treated as a general theory of micro-phenomena—a bunch of models. Quantum mechanics (QM)
RELATIONSHIP BETWEEN QUANTUM GRAVITY AND GENERAL RELATIVITY IN PHYSICS
General relativity is only one of the pillars of modern physics. The other is quantum mechanics, which describes what happens at the atomic and subatomic scale. Its cutting edge manifestation,
Value of H, space-time patterns, vacuum, matter, expansion of the Universe, alternative cosmologies
To the experimental uncertainties on the present value H 0 of the Lundmark - Lemaitre-Hubble constant, fundamental theoretical uncertainties of several kinds should also be added. In standard
Suche nach Zwei-Boson-Resonanzen im vollhadronischen Endzustand mit dem CMS-Detektor = Search for Diboson Resonances in the Full-Hadronic Final State with the CMS Detector at $\sqrt{s}$ = 13 TeV
A search for new resonances decaying to WW, WZ or ZZ in the all hadronic final state using 77.3~fb$^{-1}$ of data taken with the CMS experiment at the CERN LHC at a center-of-mass energy of 13 TeV is
Nonlinear dynamic interpretation of quantum spin
In an effort to provide an alternative method to represent a quantum spin, a precise nonlinear dynamics semi-classical model is used to show that standard quantum spin analysis can be obtained. The
Non-gravitational Effects of the Metric Field over Complex Manifolds
Objective of this work is to study whether some of the known non-gravitational phenomena can be explained as motion on a straight line as gravity is treated within General Relativity. To do that,
The Shelter Island Conferences Revisited: “Fundamental” Physics in the Decade 1975–1985
The focus of this broad historical overview of “the steady evolution of theoretical ideas” from Shelter Island I in 1947 to Shelter Island II in 1983 is some of the developments in “fundamental”
Real Projective Geodesics Embedded In Complex Manifolds}
Focus of this study is to explore some aspects of mathematical foundations for using complex manifolds as a model for space-time. More specifically, certain equations of motions have been derived as

The XXXIV Annual Conference of SISFA was divided into various sections that have touched issues concerning essentially the History of modern and contemporary Physics and Astronomy, although there
Communicating uncertainty about facts, numbers and science
TLDR
This interdisciplinary review structures and summarizes current practice and research across domains, combining a statistical and psychological perspective, and develops a framework for uncertainty communication in which three objects of uncertainty—facts, numbers and science—and two levels of uncertainty: direct and indirect are identified.
