The Physics Teacher
April 2024
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.
