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)
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
Società Italiana degli Storici della Fisica e dell'Astronomia. Atti del XXXVII Convegno annuale / Proceedings of the 37th Annual Conference
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
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.


Mathematical Formulation of the Quantum Theory of Electromagnetic Interaction
The validity of the rules given in previous papers for the solution of problems in quantum electrodynamics is established. Starting with Fermi's formulation of the field as a set of harmonic

Quantum theory of gravitation
It is possible to construct the non-euclidean geometry of space-time from the information carried by neutral particles. Points are identified with the quantal events in which photons or neutrinos are
On a Gauge Theory of Elementary Interactions
One of the problems engaging current interest in field theory is the problem of determining which fields are (~ elementary ,> in some fundamenta l sense, and which are not. An equally, if not more,
The renormalized propagation functions DFC and SFC for photons and electrons, respectively, are investigated for momenta much greater than the mass of the electron. It is found that in this region
Broken Symmetries and the Masses of Gauge Bosons
In a recent note' it was shown that the Goldstone theorem, ' that Lorentz-covaria. nt field theories in which spontaneous breakdown of symmetry under an internal Lie group occurs contain zero-mass
CP Violation in the Renormalizable Theory of Weak Interaction
In a framework of the renormalizable theory of weak interaction, problems of CP-violation are studied. It is concluded that no realistic models of CP-violation exist in the quartet scheme without
Quantised Singularities in the Electromagnetic Field
The steady progress of physics requires for its theoretical formulation a mathematics that gets continually more advanced. This is only natural and to be expected. What, however, was not expected by
Discovery of Weak Neutral Currents
Following the tradition of previous Neutrino Conferences the opening talk is devoted to a historic event, this year to the epoch-making discovery of Weak Neutral Currents four decades ago. The major
