We’re excited to add another simulation to our growing mathematics collection. With the new Graphing Lines simulation, explore the world of lines. Investigate the relationships between linear equations, slope, and graphs of lines. Challenge yourself in the line game!
If you’re running Java 7, we strongly encourage you update to Java Update 13 (build 1.7.0_13-b20). This latest Java release includes critical security patches and makes running Java in the browser more safe.
Get the upgrade here:
And if you’d like to learn more about the update, read about it here:
Note to Mac Users: to run our 3D simulations, Molecule Shapes or Plate Tectonics, you will still have to downgrade to Java 6 as described in our previous blog.
Have you tried Plate Tectonics or Molecule Shapes, but couldn’t get these sims to run on your computer?
Well, try again! We’ve upgraded both to work on as many platforms as possible. Please note that the simulations use LWJGL for the 3D graphics. Unfortunately, at this time LWJGL does not support Java 7 on Mac OSX. For to run these simulations, it is necessary to downgrade your Java to version 6. To learn how to do this, see

If you’re still having troubles, please let us know so we can ensure that it works for everyone.

See Tim Holt on El Paso Independent School District’s (EPISD) Digital Discoveries show how they use PhET.
Thanks Tom for the Shout Out!
Have you seen our latest video Using PhET in Lecture: Going Beyond Demos?
See how to use PhET simulations in powerful ways that engage a whole class in a large lecture setting. See examples of how you can incorporate clickers and other instructional techniques to deliver engaging interactive lecture demonstrations that will make maximum impact on student learning.
On January 10th, 2012, the United States Computer Emergency Readiness Team (US-CERT) released a bulletin regarding security issues with Java. One of the recommendations in this bulletin is to disable Java in web browsers. In many cases, this will prevent running PhET simulations directly from the PhET web site.
If you are a user of PhET simulations, are currently running Java 7 and want to still be able to use PhET simulations, we recommend that you take the following steps:
PhET will continue to monitor the situation surrounding Java security issues and will send out an update when the problems are fully resolved.
If you have questions or concerns regarding this, please contact us at phethelp@colorado.edu.
Thank you for using and supporting PhET Interactive Simulations!
The University of Colorado Office of Information Technology will be performing a scheduled system reboot of the PhET server on Thursday, January 10 at 11:00 PM Mountain Standard Time. During this time, PhET (http://phet.colorado.edu) will experience periods of unavailability. We expect that the outage will last only 10 minutes and that we will be back online very quickly. However, if you experience issues, please e-mail the PhET Help Desk at phethelp@colorado.edu.
Thanks for your patience during our system maintenance.
Happy New Year!
And thank you to all those who pledged their support to PhET in 2012. We are looking forward to an exciting 2013 with new simulations as well as making our more popular sims tablet compatible.
Don’t forget to try the HTML5 prototypes at:
A big ‘Thank You!’ to all of you who have already contributed to PhET during this campaign!
If you have considered a donation, but haven’t gotten to it yet, there’s still time!
It takes a village – our village of PhET users and supporters – to continue to bring these high quality science learning tools to teachers, like Amy from Texas, and their students.
“It truly brings tears to my eyes—not something done easily— when I can give them access to something as wonderful as your program.” – Amy P., 4th grade teacher, Dickinson, TX
Please become a PhET supporter with a donation today. Every donation – from small $10 donations to larger gifts – helps to fund the effort, and is much appreciated!
Thank you and Happy New Year!
In our new video, Nobel Laureate Carl Wieman explains why he donated his Nobel prize money to PhET and why it’s important for our community to continue to support PhET.
Consider donating to PhET this holiday season – now through Network for Good to support both anonymous and recurring donation options.
