Description:

There have been two more formal publications on Big History recently: one a journal article hinted at in the previous post written in part to honour the memory of Erich Jantsch, the other a book chapter, as well as an informal podcast episode in the FuturePod series.Today was the last class ever of the Swinburne MSF (2001 2018) something that has been coming for a long time (announcement of closure was back in May 2016). In the previous post in this series, I gave the rationale for undertaking this extended (re-)examination of the geometry of the semi-symmetric metric connection (SSMC): essentially, it represents (to my mind) the most ultra-minimalist extension to General Relativity (GR) at all possible or so I thought back in the early 1990s given that it introduces precisely one new object a vector field as part of the connection.In gauge field theories the connection carries the gauge field, while the curvature corresponds to the field strength, a view that was argued in a book by Göckeler and Schücker (1989), which I had also been reading at that time. Since electromagnetism is often introduced as the archetypal gauge field in mathematical treatments of differential geometry (such as that by Göckeler Schücker), it seemed to make intuitive sense to me that introducing electromagnetism into an extension of GR intended to model electromagnetism by way of a geometrical object might require it to enter by way of the connection, rather than as an additional field just lying around in spacetime, as it is in Einstein-Maxwell Theory (EMT). Hence, in this view, the SSMC is an obvious candidate.

Many years ago (getting close to 30 now), while doing my PhD (Voros 1996) in theoretical physics on mathematical extensions to General Relativity and in particular, on Einstein s own unified field theory I happened across a book by Jan Schouten (1954) called Ricci-Calculus, which was an introduction (by a mathematician) to tensors and their applications, especially to geometrical thinking and analysis.
