All ChemThink Tutorials are Finished

Category : High School · No Comments · by April 15, 2020

“Chemical Reactions” and “Isotopes” are ready!

With the addition of the last two tutorials, all of the original ChemThink tutorials are now complete.  Now that they are HTML5-capable they will run in any modern browser.


It has been 4 years and 2 months since I started working on “The Particulate Nature of Matter”.  I feel like I just finished my dissertation.

Please spread the word that the original ChemThinks are all complete!

Also, I doubled the number of server CPU cores and RAM to support the increased usage over the next few months.  This cost several hundred dollars, but it is worth it to minimize the amount of friction for students working on ChemThink from home.  If you haven’t done so already, please consider donating on
