New high resolution, optical spectroscopy of the high mass X‐ray binary LMC X‐3, shows the spectral type of the donor star changes with phase due to irradiation by the X‐ray source. We find the spectral type is likely to be B5V, and only appears as B3V when viewing the heated side of the donor. Combining our measurements with those previously published, and taking into account the effects of X‐ray irradiation, results in a value for the donor star radial velocity semi‐amplitude of K_o = 256.7 ± 4.9 km s⁻¹. We find the mass of the black hole lies in the range 9.5M_⊙ ⩽ M_X ⩽ 13.6M_⊙.

A computation of the electron mass is found utilizing a generalized holographic approach in terms of quantum electromagnetic vacuum fluctuations. The solution gives a clear insight into the structure of the hydrogen Bohr atom, in terms of the electron cloud and its relationship to the proton and the Planck scale vacuum fluctuations. Our electron mass solution is in agreement with the measured Committee on Data of the International Council for Science (CODATA) 2014 value. As a result, an elucidation of the source of the fine structure constant, the Rydberg constant, and the proton-to-electron mass ratio is determined to be in terms of vacuum energy interacting at the Planck scale.

In general, sound waves propagate radially outwards from a point source. These waves will continue in the same direction, decreasing in intensity, unless a boundary condition is met. To arrive at a universal understanding of the relation between frequency and wave propagation within spatial boundaries, we explore the maximum entropy states that are realized as resonant modes. For both circular and polygonal Chladni plates, a model is presented that successfully recreates the nodal line patterns to a first approximation. We discuss the benefits of such a model and the future work necessary to develop the model to its full predictive ability.
