About Science Notes 6

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.

Our Philosophy

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.

    I am the Head teacher of Science at an Australian High School and am interested in using your circle periodic table https://sciencenotes.org/downloadable-periodic-table-circle-tiles/
    and I understand it is copyrighted.
    It would be used in the school as a giant mural in a hallway to be made interactive with the Aurasma app. but for this to happen I need to be able to either access a very high resolution copy or get permission to rework/recreate it using adobe illustrator.
    Would this be OK is a high resolution copy was made available and used with your permission, or would I be able to adapt your idea to suit our needs (eg recreate a very similar copy)

    Thank you in advance

    Hello. I would like to use your Colorful Periodic Table in one of my videos. I understand that it is copyrighted and would like to ask permission before using it. I think I will find another table if you do not reply. I could not find information regarding asking questions, so I hope you will find this here in time. Thank you.

      Yes, you can use it in your video. We request the table not be reproduced online (able to be downloaded somewhere else) to protect ownership in search engines. It doesn’t sound like that is an issue for this project 🙂 Good luck with the video!

    I am presenting as the Conference for the Advancement of Science Teaching in Houston TX this month. It is the state science teachers conference in Texas. I am teaching teachers how to teach students to make accurate precise scientific measurement. I was wondering if I could use the article on your website titled “What Is the Difference Between Accuracy and Precision?” as part of this presentation. I would specifically like to reproduce it in a printed form for the participants. I would give you full attribution and include a link to your website.
