Mac OS X Quantum Simulations 66
Jeremy Lee writes "There are some 'educational' apps that transcend the merely interesting, and expand you mind with the force of a crowbar in the cerebellum. Celestia is one. Atom in a box is another. I keep it handy on my new iBook to blow the minds of chemist friends. It only runs on PowerPC Macs, but it's almost a justification for getting one. It should be used in schools to teach chemistry." Celestia is also great (and available for other platforms) ... I couldn't download it from the main link on the page, but was able to get it from SF.net. But if you really want to amaze your friends, turn your Mac into a Desktop Cray.

I thought the CosmoSaver screensaver was good but Celestia is amazing - if you have OSX, or a friend with OSX, or if you are anywhere near an Apple store go get a look at it. When the camera zoomed out from Earth and showed the entire Galaxy for the first time my jaw dropped...

There is something to be said about zipping to objects on the other side of the universe in just a few seconds. And it runs surprisingly well, even on my Late 2001 iBook (600MHz w/ 384MB of RAM and 8MB VRAM). This program is the ultimate for armchair (or bar-top as my case would be at the moment...gotta love wireless internet in Japan) astronomers. It does seem to have problems rendering Earth (as someone else mentioned the mirror effect somewhere in the comments of this story) but everything else is just amazing.
If you haven't downloaded this software yet, then the terrorists have already won...err...no, that isn't right. But seriously, get it and get it like now...as in yesterday! It is AWESOME.
BTW, on a side note, has anyone had any success compiling Celestia from source. I tried but failed (unfortunately, don't remember why). No particular reason to compile from source, but I wanted to try and see if it would be a bit more optimized. Anyway, I had difficulty. Anyone else?
Cheers. :)

However, I'm I the only one who still sees Skylab orbiting the earth? Shouldn't it be in a geostationary orbit, approximately 0km above Australia?

The situation for the UNIX version of Celestia is more complicated. It certainly works on x86-based systems running Linux. As of version 1.1.3, it should also work on PPC based Linux computers as well.

Celestia is fantastic.
X-Plane, also (if you can get it all together and all running), is really great. I'd love to see the two merge, somehow, heh heh

On MacOSX 10.1.5, Celestia apparently wraps a realtime mirror image around us. Does not apply on any other planets.

Desktop Cray? (Score:4, Insightful)
I have looked in the forums and the homepage, and it almost seems as if it is a joke.
Does it work?
Does it actually make a speed improvement?
How does it work?
With software that possibly emulates a 512bit integer processor (or so I gathered from the website) I would assume a massive slowdown from emulation.
Before I actually try this software, would someone let me know of their experiences with it?

Thank you for informing me about the unusual (to say the least) coincidence on my name being an anagram for Seymore Cray. I had heard before that his name was an anagram of mine! Life is stranger than fiction, hey?
Also I feel it's important to state for the record that I am not the CEO of XOSX Software, that's Dr Gette Lyfe.

You want the cerebral cortex. That's where the thinking happens. The cerebellum is a funny little bit in the old middle bit of your brain that keeps your balance working. Applying a crowbar to it would merely have a simmilar effect to many pints of beer...
