3D Slicer - http://www.slicer.org/ - gives you detailed 3D models for the brain generated from CT scans. You can use it to reconstruct other organs as well.

I think this happens because it is increasingly difficult to accumulate all the knowledge necessary to make you a specialist in your field (and to give you the opportunity to discover new things) until the age of 30.

I follow and sometimes contribute to a couple of forums: http://www.unix.com and http://serverfault.com/.

In the late 90s and early 2000s operating systems were compared with airlines, in a humorous manner: http://www.webaugur.com/bazaar/53-what-if-operating-systems-.... Now it seems that the comparisons have become more serious than that. I'm using Unix/Linux every day, and I don't feel like I'm living in a monastery.

Is it possible to increase the range of the circle determining my location to an entire city (or even more)? Great idea.

EDIT: by range of the circle I mean radius/diameter.
