    Do I Need to Buy Microsoft Office?

    By Posted on 6.12.2008 6 Comments

    Not necessarily. It’s hard to ignore MS Office, but you don’t need to blow 400 bucks to get your work done. In fact, you don’t need to install any programs at all. Sign up for the free Google Docs (documents.google.com) or Zoho (zoho.com), and you can do everything in a Web browser. The programs look similar to Word, Excel and PowerPoint and offer all the same features (save for a few lesser-used ones like certain spreadsheet formulas). Zoho even kicks in a few extra applets like a Wiki-building tool. Best of all, these applications let you access your files from any computer that’s online. If you don’t have reliable Internet access or are more comfortable installing programs on your computer, there’s no shortage of competition, either.

    Quantum Physics in a Glass

    By Posted on 7.25.2008 11 Comments

    Before the discovery in the 1920s of quantum mechanics—laws that explain the way the world works on the very small scale of atoms and electrons—the fact that bleach and peroxide glow when mixed would have seemed like just another chemical reaction that gives off light, like fire or fireflies. But it’s actually a glimpse into the impossible.

    i was actually going to try mixing bleach and hydrogen peroxide... they probably should have put the comment about that not working closer to the beginning
