Rrenormalize replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Your equation is not an integrability condition that must be satisfied by ##e,\omega,\Gamma##. Instead, it simply defines the spin...

Rrenormalize reacted to ergospherical's post in the thread I A sufficient condition for integrability of equation ##\nabla g=0## with
Like.
I'm struggling a bit to follow your train of thought- The tetrads ##e'## and ##e## are related by a (local) Lorentz transformation... -
Rrenormalize reacted to russ_watters's post in the thread How do people explore new ideas in physics? with Like.
There's really no way around the fact that the barrier to entry (being educated in physics) is required for practical reasons. There's...

Rrenormalize replied to the thread History Biographies, History, Philosophy of Physics.Paul Merriam's arXiv paper reads more like philosophy, with a capital P, not physics. All of its recent references appear in philosophy...

Rrenormalize reacted to PeterDonis's post in the thread A Self-gravitating systems and MOND with Like.
That's correct. And yet your post #8 does exactly that, as you confirm in your post #10. Therefore, this thread will remain closed.
