"A cool new way to improve behavior and engagement in your classroom. You can give instant time feedback to your students using your iPhone--very cool! If you're creative, there are many ways to use this tool starting today!"
You can search Google and Wolfram Alpha at the same time. This is a handy tool for educators and students alike. Wow. (I wonder how long Google and Wolfram will let it stay - awesome while it lasts, though.)
