Editing DarkMatter/VeraRubin (section)

===Primack at UC, Santa Cruz===
That same month (June 1983) I received a (hand-written) letter from Dr. [https://en.wikipedia.org/wiki/Joel_Primack Joel Primack] (a physicist at UC, Santa Cruz) containing the following text:
<table border="0" align="center" width="60%"><tr><td align="left">
<font color="darkgreen">"I'm working on a review of dark matter for Annual Reviews (with Sandy Faber, George Blumenthal and Doug Lin) and would very much appreciate it if you would send me a copy of your paper on gravity weakening with distance as an explanation of constant rotation curves, referred to in <b>Vera Rubin's recent ''Scientific American'' article</b>&hellip; Please also send a copy to George Blumenthal at UC Santa Cruz.  Thanks very much!"</font>

Receiving this request from Joel Primack was exciting for me on two fronts:  (1) Having my work cited in a high-quality review article would significantly enhance its visibility.   (2) I had only recently (1978) earned my doctoral degree in astronomy from UC, Santa Cruz and had completed courses taught by both [https://en.wikipedia.org/wiki/Sandra_Faber Sandy Faber] and [https://en.wikipedia.org/wiki/George_Blumenthal George Blumenthal], so I knew them well and was happy to hear that they had become aware of research endeavors that I was pursuing beyond the focus of my dissertation research.
