Hi there! Welcome to Science Notes. We got our start back in 2001 writing About.com’s Chemistry website, but have an interest in all aspects of science (not just chemistry), so we started this site as a way to expand on interests.
As you can tell, we follow astronomy quite closely and enjoy growing crystals in spare time. Anne has a thing for fire, so we have a lot of pyrotechnic projects. We’re best known for our periodic tables. If you have particular areas of science you’d like to see covered, be sure to let us know.
We live in South Carolina. We have (too many) cats, including two with a tendency to help with projects and writing. In our down time, we’re into video games, swimming, and kayaking.
About Anne Helmenstine
Anne Helmenstine has a Ph.D. in Biomedical Sciences from the University of Tennessee-Knoxville/Oak Ridge National Laboratory and B.A. degrees in Physics and Mathematics from Hastings College, Nebraska. She has worked as a scientist, college professor, scientific consultant, photojournalist, and science writer.
When About.com became Thoughtco.com, Anne stayed on the team, but expanded science coverage to include chemistry, physics, math, biology, astronomy, psychology, and animals. She explains how stuff works on Science Notes, writes projects, and manages the site’s newsletter and social media. She uses Daz, Bryce, and other programs to render 3D images for the site and takes original photos.

We believe in free information. We offer original graphics as posters, t-shirts, etc., on RedBubble, but all the content on Science Notes is free to download and print for personal use. (It’s all copyrighted, so we’ll send your host a nastygram if you put it on your site or try to sell it. Stealing is bad.)
Yes, the site has ads. Believe it or not, we make our living doing this! We prohibit certain types of ads to keep the site kid- and school-friendly. We hate pop-ups, anything that autoplays sound, or any ad that covers content. If you see something like that, let us know and we’ll go on a search and destroy mission.
