The Neutron, Gauge Bosons and Dark Matter in the Standard Model of Particle Physics| Chapter 3 | New Frontiers in Physical Science Research Vol. 7

 The life of the neutron, which was initially proposed to legitimize the stability of the nucleus, is very comparable to the postulation of dark matter providing cohesion to galaxies and clusters of galaxies. However, the existence of the neutron has existed verified as an fundamental part of the nucleus, which is connected within allure integral makeup in the Standard Model (SM) of particle physics. The Standard Model that started with the electron and the proton, now with in addition a hundred particles, presents cracks in few parts that lead to amend the veracity of the believes and models. Here it is established that all theories search out some range false and, then, any model will too be false, which is forever a specific few the theory. In addition, as accompanying several additional entities, even the existence of gauge bosons is queried and in particular, concerning dark matter, through a mathematical estimation, it becomes clear reason it has not been attainable to incorporate it into the Standard Model. Likewise, it is irrefutably showed that the introduction of the dark matter suppose is superfluous, what the high speeds of leading rotation that have been driven experimentally are tentatively explained accompanying the stellar movement described in this work.

The Presence of a Revolution Load and Its Rotational Speed of Half the Speed of the Journal Are Necessary Conditions for the Half-Frequency Whirl of Radial Bearings | Chapter 3 | New Insights into Physical Science Vol. 5

 

In the radial sliding bearing lubrication theory, the half-frequency whirl phenomena are commonly
introduced. However, the correlation of the half-frequency whirl theory with the measured resonance
phenomenon is low. This paper studies the establishment of the half-frequency whirl theory and finds
that while researchers are aware of the half-frequency whirl, they disregard the necessary conditions
of its occurrence. If there is no revolution load, then the half-frequency whirl does not comply with the
principle of minimum potential energy. If it does not conform to the principle of minimum energy
dissipation, then the half-frequency whirl does not exist. Only when the revolution load exists and its
speed is half the speed of the journal will the half frequency whirl occur. Engineering oil whip results
from the vibration of the rotating system. A precise radial sliding bearing lubrication theory should use
cylindrical coordinates, consider the compressibility of the liquid, and consider the surface shear
stress in the journal bearing capacity calculations.
