Conventional holography proves this is possible. Portions of the image of a hologram can appear at points both closer and farther than the plane of the hologram itself. Furthermore, reflection holograms can be recorded in opaque media, so

"Most of us who went to American grade schools can remember long hours of copying articles out of encyclopedias. 'The abode of the penguin is a hard and difficult one.' It was called doing research. Then in college we found that it was also

Down now for TOS violation, but +1 anyway for the effort. Any chance of summarizing the infographic textually somewhere?

To crawl Google URLs of the form google.com?q=x would be to disregard http://www.google.com/robots.txt , which seems like bad netiquette to me.

The page contents are being crawled and added to the index, but by Bing Toolbar users, not a computer program. I consider that to be an underhanded way to circumvent robots.txt, but others might not.

If you're willing to shell out a few bucks, I highly recommend mekentosj's Papers over Mendeley. Among the free options, I prefer CiteULike (web-based; http://www.citeulike.org ) or Bibdesk (Mac OS X; http://bibdesk.sourceforge.net ).

For real analysis, I'd recommend that you pick up a copy of "baby Rudin" regardless, but for learning real analysis, I'd recommend a book like "A First Course in Mathematical Analysis" by Burkill. Other viable options include "Calculus" by

You're hardly the first person with this idea. There are many corporations already working in this sector--they're called government contractors.

A few of my favorites, chosen from computer science and from physics: D. E. Knuth, "An empirical study of FORTRAN programs," Software: Practice and Experience, vol. 1, no. 2, pp. 105-133, 1971. http://dx.doi.org/10.1002/spe.4380010203

I remember that chapter from Surely You're Joking, Mr. Feynman quite well. One of my favorite passages is the following, which is the source of the title of the chapter: We came to a certain book, part of a set of three supplementary

Another Papers user here, and I also use a combination of CiteULike ( http://www.citeulike.org ) and Bibdesk ( http://bibdesk.sourceforge.net ). I find either system both easier and more powerful than Mendeley.

That query calculates "median planet volume / volume of a small grain of sand", as mentioned by the grandparent poster. I believe it is still an open question how to get Wolfram|Alpha to calculate "total planet volume / volume of a small g

The query "total volume planets" yields a reasonable answer for that part of the problem, but I can't convince Wolfram|Alpha to divide it by "volume of a small grain of sand"... :-/

I was pretty sure I tried every permutation of the words "average," "height," and "human," but I guess I didn't. Bravo.

I've run into some weird bugs trying to perform calculations in Wolfram|Alpha. For example, I cannot come up with any query for the general question "human height vs Empire State Building" that works, even though the separate queries "hei
