Who the hell says "grok" anymore???????
I do.
It's a good word, whose meaning seems to match its sound.
Next question?
So its meaning is "the sound a frog makes in a pond"?

All I'm saying is that back when Heinlein wrote "Stranger in a Strange
Land" it was a wonderful word and people used it freely but now it
comes across as dated and younger folks have never heard it but in
reality I wish such were not the case for I agree with everything said
here in defense of it and maybe I wish I had more courage to trot it
out every now and again.

I immediately thought about this book when I saw the subject line, but I presumed it had other slang use.

I especially liked "Door into Summer" , because of the time travel, and the tom cat. I have a Tom, and now its turning almost winter and he is constantly complaining about the lack of this door.

About the Einstein equation : quite impossible to "grok" it.

Start with Clifford Will's "Was Einstein right", with the thought experiments that inspired Einstein to the theory, which led to the equations.

In no time, you will outgeodese those who claim to understand the equations, but absolutely do not, because in contradiction with Einstein's Original thought experiments.

Only solutions consisting of a black hole are well known, and those are worth studying in order to get more insight in the matter.

Frame dragging really gets dramatic with black holes, and illustrate the issue better.

As a result of this frame dragging, the inertia made by the universe looses against the inertia of the Black hole, and the orbits of objects around a BH catastrophically decay. Compared to that, the Mercury perihelion shift is peanuts.

Beware of GR "specialists" that do not grok inertia.
