Where does the name "PhET" come from?
Our project originally focused on physics sims, and was hence named the *Ph*ysics *E*ducation *T*echnology project, or *PhET*. When we branched into chemistry, biology, mathematics and other areas, we decided to keep the name *PhET*, but to no longer describe it as an acronym.
How do I embed PhET simulations?
Click the "Embed" button under the simulation you would like to embed. This will bring up a text box of html code that you can copy and paste in order to embed the sim. Flash sims may be directly embedded or linked via an image to launch the sim. Java sims may only be linked via an image to launch the sim.
Some LMS may require you to use "https://" for the URL of the simulation.
I am a corporate partner. Do I need to pay to use sims in my product?
