I'm adding links on here a few at a time. I'll try to keep them either useful or interesting, or maybe even both.

Post-It Notes 3.0 Lite is a useful free download. I use it to study by leaving information I need to know visible on my screen. Each time I re-boot my computer, the electronic Post-It Notes are on the desktop.

DreamCalc is a program that replaces the simple calculator that comes with Windows. It is a desktop scientific calculator. I've used the Free Version of DreamCalc a bit, and it works fine. I haven't tried the "Unlimited Free Trial" of DreamCalc Pro. It looks even better, but the download page says that after a certain amount of time you will be regularly reminded that you haven't paid for DreamCalc Pro. I'm sticking with the Free Version.

The sprawling website of Helmer Alaksen has a lot of interesting information. It is officially a mathematics website, but there are web links about calendars, sundials, culture, you name it. There is even a link called "Why Calculus?"

ScanView can be downloaded from Stanford's Digital Michelangelo Project at no cost. You can then use your mouse to turn a 3D David around and see him from different angles. While you're turning him, he loses some detail, but the detail comes back pretty well once you stop moving him.

Turning the Pages is a British website that allows you to virtually turn the pages of books like the Koran and a Leonardo Notebook. I've only looked at the Leonardo Notebook, so I can't really judge the Turning the Pages concept overall. But I can say it was interesting to browse through one of Leonardo's notebooks.

The Terror of Salvation is an analysis of the Last Judgement by Michelangelo written by Dr. John W. Dixon Jr., Professor Emeritus at the University of North Carolina at Chapel Hill. I took Introduction to Humanities during the Spring 2004 semester, so tried to find some web pages that do a good job of explaining possible meanings behind different works of art. This analysis does a great job of bringing up possible explanations and/or interpretations of the Last Judgement. Dr. Dixon makes it clear when what he is telling us is factual, and when he is stating opinion. He also does a good job of explaining why he feels the way he does about some things. (For instance, he makes a good case in attempting to relate the ceiling of the Sistine Chapel to the Last Judgement. I'm convinced. Jonah is the key.)

This online version of the School of Athens by Raphael is clickable. You can click on many of the people in the fresco to find out which philosopher they represent, and who had the honor of being the model for each.

If you want to learn more about the Sistine chapel and it's art, this is the site to visit.

If you're looking for some good language software and are willing to pay about $40, then I suggest LanguageNow!. LanguageNow! has audio, video, words are highlighted as you hear a paragraph spoken, etc. It's a good program.

If you're taking Astronomy, or if you're interested in Astronomy, you might want to visit astronomynotes.com. Nick Strobel created these documents for an astronomy class he teaches, and this website is well known and respected by many people. Oh. It's easy to understand, too.
