Hey,
Whenever I read Relativity I get stuck around Gaussian coordinates, i can't seem to find much out about them, do they have another name? does anyone know any good resources explaining them?
or am I just in over my head?

thanks guys,

If we don't know what aspect of it you didn't understand, then there's no way for us to write an explanation that would work better for you than the one you've already read.

I'm guessing that you are reading Einstein's popular book, "Relativity, the special and general theory", http://www.bartleby.com/173/25.html?

I'm not sure what you don't understand. Gaussian coordinates are just like using graph paper, except that the lines aren't necessarily straight...

Hi,
Yeah. I get it now, I found a different (better) translation, Thanks.
 

Thread 'I don't see how a black hole's event horizon can be crossed'

OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...

Thread 'Question about Parallel Transport'

In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...

Thread 'Synchronizing clocks in an inertial frame if light is anisotropic'

ASSUMPTIONS 1. Two identical clocks A and B in the same inertial frame are stationary relative to each other a fixed distance L apart. Time passes at the same rate for both. 2. Both clocks are able to send/receive light signals and to write/read the send/receive times into signals. 3. The speed of light is anisotropic. METHOD 1. At time t[A1] and time t[B1], clock A sends a light signal to clock B. The clock B time is unknown to A. 2. Clock B receives the signal from A at time t[B2] and...
