Guest Thinkers — February 16, 2011

Y’all come back now, hear?

How many times did I hear the title of this post when I was growing up in Virginia and visiting my relatives in the South?!

Hope you can join me, Miguel Guhlin, and Doug Johnson (and maybe a mystery guest?) at EdTechTalk this evening for the Women of Web 2.0 broadcast. We will be talking about issues related to K-12 technology leadership and administrators. The fun starts at 9pm Eastern / 6pm Pacific. You also can log in to the chat room (use the link on the left) to interact with us and our hosts, Vicki Davis, Cheryl Oakes, Jen Wagner, and Sharon Peters. If you can’t join us this evening, you can visit the Women of Web2.0 archives later on and download our podcast.

The big idea of Grand Unified Theories of physics

If the electromagnetic and weak forces unify to make the electroweak force, maybe, at higher energies, something even grander happens?
