Are you sure “Sphere” refers to “hemisphere” and not simply to earth? After all, she’s trapped on earth and not on the celestial sphere.

"This totally occupies her mind, and she feels frustrated that she can only learn about those mind-boggling places, and not visit them herself." Wow. She must have been in a class? She's "totally" occupied? She's frustrated? (Not wistful, or resigned, or just aware of a fact mind you.) She isn't just thinking about the size of space, but apparently really, really wants to actually travel there. (To where, exactly? What "mind boggling" places? "Space"? Seems rather general.) You got all that deep and specific feeling from just her using the word "trapped"? Looks like reading a lot into things, to me.

:I try to not to make the explanations too dry; they are and should often be interpretations to some extent. On the other hand yeah, you are probably right that I read too much emotion into it. I changed the things you commented on. –[[User:St.nerol|St.nerol]] ([[User talk:St.nerol|talk]]) 18:29, 7 August 2013 (UTC) | :I try to not to make the explanations too dry; they are and should often be interpretations to some extent.

:@CFoxx - Absolutely. In XKCD, there are no shades of grey.

Hey, what the hell are you doing? "The sphere she mentions..." is absolutely wrong, the word ''Sphere'' appears only at the title and the title text! Megan is just impressed by the vast size of the universe.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 16:21, 7 August 2013 (UTC) | Hey, what the hell are you doing?

:She does mention a sphere, so I changed it back.

After some more thoughts on this, why nobody (even myself) did raise the idea that Randall talks about both interpretations? Nevertheless, if the sphere is interpreted as the surface of the Earth there is a need to explain the geoid discrepancy to an ideal sphere, as mentioned in the very first post here.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 19:51, 7 August 2013 (UTC) | After some more thoughts on this, why nobody (even myself) did raise the idea that Randall talks about both interpretations?

This "a sphere is a surface and has no surface" is too much nitpicking. Wikipedia (http://en.wikipedia.org/wiki/Sphere) talks about calculating the surface area of a sphere. I think "surface of sth" is not very rigorously defined. Often two dimensional manifolds are called surfaces, and a sphere is one, and the surface (different meaning) of the earth is roughly a sphere. What a sphere doesn't have is a border.

The is trapped on the surface of this sphere, since you can walk on it forever, without ever leaving it[[User:Oscar|Oscar]] ([[User talk:Oscar|talk]]) 12:20, 8 August 2013 (UTC) | The is trapped on the surface of this sphere, since you can walk on it forever, without ever leaving it[[User:Oscar|Oscar]] ([[User talk:Oscar|talk]]) 12:20, 8 August 2013 (UTC) | ||
