#2Light on content but had a neat riddle (I actually "solved" or guessed it pats self on back)
"You're standing on the surface of the Earth," Musk begins, according to the book. "You walk one mile south, one mile west, and one mile north. You end up exactly where you started. Where are you?"
Answer in the article.

This riddle doesn't look hard at all (solved it nearly instantly after reading it), but I'm not sure I could provide an instant answer during such stressful conditions as mentioned in the article.

Depends if where you started is based on coordinates or a location on the ice, and how long it takes you to walk the distance.
I would do nearly anything to work for him in cali.

#5The first answer to the riddle is pretty obvious but I don't see how the second answer can be correct.

Near the South Pole, there are latitudes where the circumference is 1 mile, 1/2 mile, 1/3 mile... You are 1 mile north of those latitudes.

#7I would attempt to throw him off by asking "you mean true north, geographic north, or grid north?"

ok, so haversine distance is a thing on a sphere: http://en.wikipedia.org/wiki/Great-circle_distance
You are a bit over a mile from the south pole (how much a of bit requires math i don't feel like doing, but is very important) You walk towards the pole, turn and walk west in an exactly 1 mile circumference circle around the pole (this is why the "bit" was important) and you walk back north to where you started.
There is only one valid point on the northern hemisphere (the north pole) and a ring of points at the south pole.
found the math I need! https://www.astro.virginia.edu/class/whittle/astr553/Topic16...
C = R sin(r/R) R = radius of earth aprox( 3,959) C = 1 mile solution is r+1 distance from the south pole

Aren't there multiple rings for the South Pole solution? There's the solution where you head south, circle the pole once, and head back north; then there's also the one (starting slightly further south) where you head south, circle the pole twice and go back... and so on.

is geographic != true north?
I think you missed out magnetic north, unless I have my definitions mixed up =]
