Hegel and the Becoming of Essence (Georg Hegel‪)‬

In the Science of Logic, Hegel derives essence from being. How precisely does this come about? This is an extraordinarily difficult moment in the interpretation of Hegel's logic. I have found only one essay on the subject. According to Professor Michael Baur: This is a very nice summary, but it is performed at a very high level of generality. Where in this summary is any reference to the alien terms one finds in the chapter Hegel entitles 'The Becoming of Essence' (Das Werden des Wesens)? There, one encounters 'the infinite which is for itself ' (fursichseiende Unendliche) (SL 371/WL I 384), (2) absolute Indifferenz, and inverse ratio of the factors (umgekehrtes Verhaltnis ihrer Faktoren). What do these concepts mean and what role do they play? Furthermore, Hegel insists that an outmoded theory of planetary orbit--the alternation of centripetal and centrifugal force--somehow illustrates the sublation of quality and quantity and the becoming of essence. How does bad astronomy relate to the becoming of essence? Why, when Hegel knows centripetal and centrifugal force to be bad astronomy, does he invoke it?
