Click For Summary
The discussion focuses on finding additional resources for learning the Cartan formalism, particularly examples of connection one forms and curvature two forms. Notable references include Sean Carroll's "Spacetime and Geometry," which covers an expanding universe, and Jetzer's lectures on the Schwarzschild case. Matthias Blau's lecture notes also address Schwarzschild and Kaluza Klein, while Wald's "General Relativity" includes the Schwarzschild solution. Participants suggest various online resources, including metrics and differential forms examples, to aid in understanding. The conversation highlights the need for more accessible worked examples in this area of study.

TL;DR
looking for worked examples of cartan formalism calculation of one form connections and two form connections
I am learning the cartan formalism from the book Relativity Demystified. It has a few examples. I am looking for more examples in video, notes, or books of the work calculations of the connection one forms and the curvature two forms to check my calculations against. My search so far has turned up not much. Thank you

Sean Carroll (Spacetime and Geometry) does the simple case of an expanding universe in his Appendix J.

Jetzer does the Schwarzschild case in his lectures. (I can't find a simple direct link -- just google for Jetzer and "advanced topics in GR".)

Matthias Blau does Schwarzschild and Kaluza Klein in his lecture notes (which are, imho, good for other things as well at a more advanced level).

Wald also does Schwarzschild in his book "General Relativity".

Is there a particular example you wanted?
 
MOVING CLOCKS In this section, we show that clocks moving at high speeds run slowly. We construct a clock, called a light clock, using a stick of proper lenght ##L_0##, and two mirrors. The two mirrors face each other, and a pulse of light bounces back and forth betweem them. Each time the light pulse strikes one of the mirrors, say the lower mirror, the clock is said to tick. Between successive ticks the light pulse travels a distance ##2L_0## in the proper reference of frame of the clock...
