New corrections to the energy of S-levels of positronium of order mα which are as large as several hundred kilohertz are obtained. A new recoil correction of order α(Zα)(m/M)m to the Lamb shift in hydrogen is calculated. This correction turns out to be too small from the phenomenological point of view. 1. Recent progress in the spectroscopy of positronium [1, 2, 3, 4, 5] triggered theoretical w...

Having once thought that we understood how some galaxies were barred and had difficulty accounting for the absence of bars in others, it now seems that we have the opposite problem. Most real galaxies have centres dense enough to inhibit bar formation, even if they have massive discs. This is also true for barred galaxies, which therefore could not have acquired their bars as a result of a self...

The paper shows that a phenomenological model of inertial induction based on a proposed extension of Mach’s Principle can produce the observed cosmological red shift in a quasi-static infinite universe. Unlike all other theories (except the Doppler effect) to explain the observed red shift this model can be verified from other local effects predicted by this mechanism. A number of such phenomen...

The MESUR solar array power model initially uses assumed values for many input variables. After landing the early surface variables such as array tilt and azimuth or early environmental variables such as array temperature can be corrected. Later environmental variables such as tau versus time, spectral shift, dust depotion, and UV darkening are dependent upon time, on-board science instruments,...
