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.
Do you have an app?
We offer an iPad app that allows native offline use of all the HTML5 sims. Find it on the App Store here. Our app is $0.99 and proceeds fund more HTML5 sim development.
We currently do not offer an Android app.
Where can I get the source code?
The PhET HTML5 and Javascript source code lives on the PhET GitHub page. The PhET Java, Flash, and Flex source code lives in a Subversion repository. To get more information about accessing, see the Source Code page.
