I would be grateful if some one would consider my following thought and indicate to me the likely mistakes, which I cannot do.
Following the paper “Why the Riemann Curvature Tensor needs twenty independent components” by David Meldgin UC Davis 2011, I understand that with a coordinates...
Thanks Fresh_42,
7 rescued fragments of Heraclitus are considered and the following 8 hypotheses about the world derived from them. These are:
1. The world is one and the same for all.
2. The world is the expression of logos.
3. Logos is common.
4. Logos is knowable by humans...
I have a third circle degree in Physics and I used to be in Theoretical Physics research. Since long, I work in a different field. Therefore, I have no contacts with the international scientific community. I prepared a paper with title “A Heraclitean approach to the Relativity Theories” and...
Is the local propagation of an entity at invariant speed a sufficient condition for its stress-energy tensor, independently of its explicit mathematical form, to be trace-free, or to have null covariant divergence, or both in curved space-time?
In the book “An Introduction To Mechanics”, by...
