Is this set a variation of Russell's paradox?(adsbygoogle = window.adsbygoogle || []).push({});

[tex]M = \{x : x \notin M \}[/tex]

I understand this formulation a lot more than

[tex]R = \{S : S \notin S\}[/tex]

because I don't understand how, for example, 1 is a member of itself. Is 1 a set? Are all numbers sets?
