... The expected pitch angle of material arms in a spiral galaxy like the Milky Way is only about 0.25 degrees. In fact, pitch angles measured from photographs range from about 5 degrees for Sa galaxies to 20 degrees for Sc galaxies. The most likely implication is that spiral arms are not material featu ...

... Thus the angular momentum of this particle, L = m v r = m r2 ω, since v = r ω. For a rigid object about a fixed axis the angular momentum L will be the summation of all the individual angular momenta. Thus the angular momentum L of an object is given by Σ (m r2 ω). This can be written as Σ (m r2) ω, ...
