Volume 61 Issue 4
This month's cover shows the pyramids of Giza against a backdrop of azure, but does not show the cosmic ray muons that are streaming through the pyramids. Don Lincoln’s article “Using cosmic rays to see the unseeable" ; tells of recent efforts by physicists to identify previously undetected voids in these pyramids by using cosmic ray muons.
