"I've been reading the material on your website for quite a few years now. I just wanted to compliment you both on the knack that you have for translating what are often quite complex scientific concepts into a form suitable for a lay audience. Not only do you get the text right, but the images and diagrams are always well chosen. You also manage to convey the excitement of the science. I don't know of another site quite like yours but I can say that I've yet to see one that matches the quality of yours, year in, year out."

"Thank you very much for the articles on the WWW! I think it is amazing what careful research tells us about the beginning of our Solar System. The articles combine both my interests in geology and astronomy. I hope you will continue this series for a long time!"

"Thank you...great article on the Sweden meteorites... we all thought they were very small...great pictures. Anyway ...one thing led to another...and I spent 3 wonderful hours exploring other articles and what you are all doing."

Searching for Ancient Solar System Materials on the Moon, Earth, and Mars: "This was a cool one -- loved how you linked all these topics together!"

"I find your articles at the perfect level for me to assimilate new research I can't read in depth. I say to myself, 'well, if they're writing about it I probably can't ignore it any longer.' I have posted your URL for graduate classes, and will do so for our upper-division undergrad classes."

"I found the level of difficulty perfect for eager to learn undergrads--not too difficult and not much jargon, and when advanced topics or analysis methods were used, they were usually well explained at a basic level."

"I hope you will excuse the unsolicited compliment, but I found your material to be wonderfully illustrative for students (and me!). Thanks!"
