Volume 62 Issue 4


This Month's cover shows BICEP2 (the Back- ground Imaging of Cosmic Extragalactic Polarization telescope) near the South Pole, which measures the polarization of the cosmic microwave background. See Don Lincoln's article “What is Cosmic Inflation?” for details about how BICEP2 fits into the cosmic inflation story.


And the Survey Says..., Astronotes, Fermi Questions, Figuring Physics, For the New Teacher, iPhysicsLabs, Just Physics, Little Gems, Physics Challenge for Teachers and Students, Talkin' Physics, Technology In The Classroom, Tricks of the Trade, Visual Physics, and Websights.
