If the conformal invariance of electromagnetism is broken during inflation, then primordial magnetic fields may be produced. If this symmetry breaking is generated by the coupling between electromagnetism and a scalar field—e.g. the inflaton, curvaton, or Ricci scalar—then these magnetic fields may be correlated with primordial density perturbations, opening a new window to the study of nonGaus...

Scaled experimentation is an important experimental approach but known to be limited by scale effects, which have the undesirable effect of changing behaviour a system with scale. Such behavioural changes can on occasions so marked as make scaled experiment almost worthless. Until very recently, there has been no universal solution this problem most experiments founded dimensional analysis and ...
