我们项目原先专注于物理仿真程序，所以命名为*Ph*ysics（物理） *E*ducation（教育） *T*echnology（技术），即“PhET”。后来，我们又有了化学、生物、数学等分支。虽然我们仍决定使用*PhET*，但我们不会告诉大家真相了。
We offer apps for both iOS and Android/Chromebook. Please see specific information by platform:
Chromebook
Android phone/tablet
iOS iPad/iPhone
All versions of our apps allow native, offline use of all of our HTML5 sims and proceeds fund more HTML5 sim development.

您不需要任何许可。PhET仿真程序是开放的教育资源，您可以自由的与您的学生分享它。
如果您将PhET用于研究，您不需要任何许可。请通过这个表格告知我们您的研究。
我们很高兴接收新的创意和完善现有仿真程序的建议。请在这里提交他们！
在您想要选择的仿真程序下方点击“插入”，这样会生成一个html码。您可以复制该码以插入仿真程序。Flash仿真程序可以通过插入或者链接的图标直接运行，Java仿真程序则只能通过链接的图标运行。
有些LMS也许需要在仿真程序地址前加上“https:/”。
