I have received several awards for my site. Here are some of the reviews, and some excerpts of email I have received.
"The search engine just for kids" is an Australian site specializing in child-safe sites. You can find their review of my site under the category: School Time - Math.
"Your Quarks to Quasars site has been selected to receive the Griffith Observatory Star Award for the week of Jan. 12 - 18 (2003) for excellence in promoting astronomy to the public through the World Wide Web."
The Canadian Mathematics Society has added my site to its "Knot a Braid of Links" project. KaBoL is a "cool math site of the week" service. Check out their Braid of Links and their review of my site -- I'm knot 185.
From Australia: "I have just returned from a three hour trip on your website. It is the most enjoyable and informative 3 hours that I have spent in the last 10 years."
From England: "I was just browsing your website - excellent work! I had completely forgotten how much I enjoyed this when I saw the film so many years ago."
