That hole in the backyard would not have gone to China. In fact, most of MeFi's readers would have ended up causing quite a leak. With so many 2d projections out there, who can blame us? There is always this introduction to map projections. You can then make your own projection or your own globe. At least it's not as hard as a 2d spacetime map of the universe (with relativity!).

Cool! I am digging my way to Spain.. Yeeha!

I like maps. But I still am not really sure what the world looks like. Since I found out about the Peters Projection I have been very distrusting of maps (thanks a lot Aaron Sorkin!).

hey, let's not leave out the "no distortion" dymaxion projection of buckminster fuller.

I like the Gnomonic projections as a cube net. I'll need to get that into Illustrator later, clean it up and make my world cube.

Nice post. That first link is from the site of Wendy Carlos, who deserves attention for other reasons as well.

[This is good]

Yup - looks like you Kiwi's are coming here to Spain, but those of us in Eastern Spain have still got a bit of a swim on our hands before we can go bungy-jumping!

According to that 2D spacetime map if I dig deep enough I'll pop out of Uranus!

/excellent, excellent humour. Thank you.

That first link is quite interesting -- I'd known in a general sort of way that the "other side" from most places was ocean, but it's striking to see how true that is: the only substantial chunks of land opposite each other are Patagonia and a piece of eastern China and Mongolia.

And the "2nd projection" link taught me the word graticule, "the lines of latitude and longitude on the globe." So thanks, ontic!

If you think you can get the Mole People to agree to let you pass through their territory you're out of your mind.

Believe me, I've tried.

Excellent post, btw

languagehat: graticule is also the term for the fine lines, forming a grid or a scale, etched in a piece of glass placed in the eyepiece of a microscope so as to appear in the same plane as the speciment being viewed. Also called "reticle".

There's a flawed assumption that when I dig my hole to China, I will dig straight down, through the center of the Earth. That would be foolish.

Besides, with the earth spinning, the coriolis effect and all, your tunnel would be curvy. Hell, you could dig all day and all night and come up a couple of feet away from where you started.

Wow, this is great. I've been working on a grad school project on maps myself, and it's really interesting to see someone else's research on the subject...

Well I was digging at an angle...
[Great post]

Slightly related: That first map reminded me of that old math insight that at any given time there are at least one set of antipodal points that are at the -exact same- temperature and elevation. Works for any two quantities as long as they are continuously varying.

I love the soundtrack to Clockwork Orange. This map makes me like Wendy Carlos just a little bit more.

I never realized how similar Australia and the U.S. are in both size and shape.

Damn, yet another reason Anna Ng and I still have not walked in the glow of each other's majestic presence.

But, if I dig a hole from Chile, I end up in China. Nice symmetry that. Chile to China.

If there's one good thing to say about the Peters Projection, it's this: it really brought to light some of the failings of the Mercator Projection. The geography community agrees that the Mercator Projection has 'fallen out of favour'. Good for them. Now they should tell the rest of the world, like nearly every classroom teacher in North America.
