As someone who had never been taught about IEX, a technology that is so integral to our daily life, it was wonderful to understand. I enjoyed very much your writing on poetry and language, which brings respite to my slower working days.
Many thanks to you, I hope this inspires more to contribute their knowledge to the world in similar ways, as I know it has done for me.

This is all very fascinating and is an important part of the landscape of the world wide web.
We agree with your opinions on dictators that deserve to disappear.

My capstone/plant design final project is to design a wastewater treatment facility that outputs ultrapure water. Your page has provided so much information to me. It's so accessible, some of this information would have taken me much longer to sift through papers and textbooks to find. Thank you so much! | |

We've never had to chance to meet, but just wanted to point out that your website has been a very valuable tool. Thanks so much for your dedication to Ion Exchange, those wonderful little balls of chemistry! | |
