This is kind of a continuation of this and this previous questions. Say one has a free "classical" field theory which is scale invariant and one develops a perturbative classical solution for an ...
I'm building a bridge out of balsa-wood strips for school, and wanted some advice. These are the specifications: Height: 2 to 6 in Length: 12 inches, plus 1-3 inches on each side resting on tables ...
I heard that people envision strong structural materials made out of graphene, but I heard it may weaken when being stack in layers. Is graphene viable for macroworld structural engineering or is it ...
Are moments relevant to the thicknesses of beams in a structure (ie. the larger the moment the thicker the beam)?
In the Large-Scale-Structure (LSS) artifacts named fingers-of-god are apparent in the redshift space and justified by "The large velocities that lead to this effect are associated with the ...
Since the CMB results of the past decade, would it be fair to say that the consensus among cosmologists is that cosmic strings are no longer considered as a (major) source for density perturbations? ...
