Kinda silly question. I would like to know how to pronounce 'Christoffel'. If I were to take a stab at it, I would guess two syllables 'Christ' (as in 'grist', with a ch as in 'Christopher') and 'offel' as in 'awful'. Am I close?

That's how I remember my GR prof saying it. Accent on the first syllable.
 
How my professor/TA/associates pronounce it as well.
 
Yep, like Christopher, but the accent is on the 'o', the second last syllable.
 
I agree with Ich- accent on the second syllable: "Crist-AH-fel", not "CRIST-a-fel". That would be an "English" pronunciation and Christoffel was German.
 
Nowadays, students calculate by hand the Christoffel symbols for a few systems as a rite of passage, and then, if they get serious about GR, use computer algebra packages to do the calculations.

A "retired" astrophysicist whom I know took a GR course in 60s when "by hand" (often quite painful) was the only method available, and he always uses the pronunciation "Christ awful symbols":biggrin:.
 
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...
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...
So, to calculate a proper time of a worldline in SR using an inertial frame is quite easy. But I struggled a bit using a "rotating frame metric" and now I'm not sure whether I'll do it right. Couls someone point me in the right direction? "What have you tried?" Well, trying to help truly absolute layppl with some variation of a "Circular Twin Paradox" not using an inertial frame of reference for whatevere reason. I thought it would be a bit of a challenge so I made a derivation or...
