However, Rutherford also had in mind the word protyle as used by Prout.
Rutherford spoke at the British Association for the Advancement of Science at its Cardiff meeting beginning 24 August He initially suggested both proton and prouton after Prout.
In a July paper, researchers measured the mass of a proton to be 1. Or do they decay with a finite lifetime as predicted by some extensions to the standard model?
Free protons are found naturally in a number of situations in which energies or temperatures are high enough to separate them from electrons, for which they have some affinity. Free protons exist in plasmas in which temperatures are too high to allow them to combine with electrons.
Free protons are emitted directly from atomic nuclei in some rare types of radioactive decay. Protons also result along with electrons and antineutrinos from the radioactive decay of free neutrons, which are unstable. The spontaneous decay of free protons has never been observed, and protons are therefore considered stable particles according to the Standard Model.

As a rule, models of nonlinear electrodynamics have a scale parameter with dimension of the field strength which defines the threshold for a substantially nonlinear regime. Contrary to this in the CNED model there is no dimensional parameter, so there is no way to scale the field and define the weak field limit.
This peculiarity, possibly, will resolve after quantization of the CNED and radiation correction calculations. Therefore the correspondence principle in our case can be formulated in the form of the requirement that the unity should be the leading term of the expansion of the model function W over the small dimensionless parameter, which is coupled to nonlinearity.
The causality principle guarantees that the group velocity for the elementary electromagnetic excitations does not exceed the speed of light in the vacuum. The unitarity criterion provides the positive definiteness of the norm of every elementary excitation of the vacuum.
The general constraints on the Lagrangian which are necessary for causality and unitarity are complicated and extremely difficult to analyze.
For the field configuration described in Ref. This restriction is not only because the Lagrangian must agree with the energy conditions.

The class of conformal electrodynamics is special, because it has very simple restrictions following from the dominant energy condition [ 38 ].
This condition claims that every time-like observer will find the field energy density to be non-negative, and the energy flux to be a causal vector time-like or null.
These requirements ensure dominance of the energy density over the other components in the stress—energy tensor.
After discussion of the general properties and the model restrictions we proceed to address the description of an exact solution for compact objects in CNED.
The appearance of two constants with the dimension of charge in the description of the point source field can be associated with the possible difference between the inertial and gravitational masses for a point-like particle. In this paper the authors distinguish thee different classes of black holes.

Phase transitions are absent for this black hole configuration. These two types of black holes have their analogs in Einstein—Maxwell theory. This type of black hole is typical for conformal-invariant electrodynamics, and we meet it in the more special case of the inverse electrodynamics model proposed in [ 35 ].
However, it should be noted that the authors did not consider fundamental restrictions on the model parameters. A global violation of this condition makes the possibility of such black holes very uncertain. Let us turn to the other exact solution for the compact astrophysical object in conformal nonlinear electrodynamics.
This solution will be an extension of Vaidya—Bonnor [ 39 ] metric to an arbitrary type of conformal nonlinear electrodynamics.

It is easy to verify that the electromagnetic field satisfies Eq.Introduction to Geometry and geometric analysis Oliver Knill This is an introduction into Geometry and geometric analysis, taught in the fall term at Caltech. In the last section we summarize our results. As it follows from the results, for the noncommutative versions of the models, the interaction energy is ultraviolet finite.
A Some Basic Rules of Tensor Calculus The tensor calculus is a powerful tool for the description of the fundamentals in con-tinuum mechanics and the derivation of the governing equations for applied prob-lems.
