SUMMARY

The discussion centers on the confusion surrounding the use of vectors in Einstein's field equations, specifically regarding the terms dx and dø. Participants express frustration over the lack of clarity in the video aimed at beginners, questioning the transition from dø to dy and the classification of these terms as vectors. The consensus is that the video fails to adequately address foundational calculus concepts, which are essential for understanding the equations presented.

PREREQUISITES
  • Basic understanding of vectors in physics
  • Familiarity with calculus concepts, particularly differentiation
  • Knowledge of Einstein's field equations
  • Experience with mathematical notation and terminology
NEXT STEPS
  • Study vector calculus fundamentals
  • Review the principles of differentiation in calculus
  • Explore Einstein's field equations in detail
  • Watch beginner-friendly videos on mathematical notation
USEFUL FOR

This discussion is beneficial for students of physics, educators seeking to clarify complex topics, and anyone interested in understanding the foundational aspects of calculus as they relate to advanced physics concepts.

I was watching a video explaining Einsteins field equations for beginners and he was giving some information on Vectors before he gets into the actual equations. He got to this equation:

I'm real confused, how does he know that dx and dø are both? Why does dø change to dy? What does the equation even mean? Please help I can't continue the video because I'm real confused on his part.

Perhaps for beginners doesn't mean for people who have not yet studied calculus?

Well that was rather snotty. I figured it out and it was just him not explaining it properly. A forum like this should be welcoming to beginners and not picking fun at their ignorance. If you're not helping then don't reply.
