Important note regarding printing
Before printing turn off the optional header and footer information. Also, make the left margin 0.75 in (1.9 cm) and the other margins 0.5 in (1.3 cm) so that the page breaks I built into the pages work as intended. Use only Internet Explorer to print as Netscape and Firefox both implement the page code a bit differently and I haven't optimized the pages for those browsers. My apologies if you are using a Mac: I cannot guarantee that you will be able to print these pages as I intended.
Some of the
files are PDFs and you need the Acrobat Reader available from Adobe. Some files are also MS Word 97 or RTF documents,
which just about anyone should be able to view. If you have trouble, try going

Science and Pseudoscience
Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What have we to offer in exchange? Uncertainty! Insecurity!
—Isaac Asimov
Hofstadter’s Law
It always takes longer than you think it’s going to take, even when you take into account Hofstadter’s Law.
—Douglas Hofstadter
The Unknown
It ain’t what you don’t know that gets you in trouble. It’s what you know for sure that just ain’t so.
—Mark Twain
Understanding the Universe
“The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy.”
—Steven Weinberg
