Everybody! Okay, I think I'm done here as I cracked my own little 'mysteries': 1) My above message notes how to get better resolution. 2) The newer issue re. Stellarium? -I found that http://www.stellarium.o rg/ offers all the FREE versions we could ever use, including a free installa ble for even Windows-based systems. 3) The (default) real "scientific" packages were NOT -never in "Scientifi c" (SL), despite this really misleading (SL) name. i.e.: SL never held the masses of excellent educational and truly scientific-based applications. i.e.: Digging in my archives I found that I had once (5 years ago?) loa ded an old Quantian distro and marveled at the wealth of really scientific applications it offered. Since my kids were so young then I didn't maint ain the distro. The Resolution: This week, after fully loading SL with extra packages and effectively inventorying apps and testing much of it all, I now loaded... the newest version of perhaps SL's 'nemesis' system, Quantian (v 0.7.9.2), And, although this version hasn't changed since March '06, I believe it is far superior to SL in its offering of real "scientific" apps and opportunitie s for my kids. So, "Scientific Linux" lab guys, how about pursuing and integrating real scientific apps into your regular iso, let alone better versions of many of the basic apps -or else change the name? That's just my recommendation. (As it stands, I can't spend any more time w/ SL.) Note: Dirk at Quantia n is not so active with the Quantian distro, as he has a regular job, but h e is very active in its wealth of topics and real scientific subject matter . -"Hat's off" to Dirk! (And we all have Stellarium on our PCs now.) Thanks. See ya! Al
