When you gaze at the mighty Great Pyramid of Giza—sometimes called the Pyramid of Khufu—you’re looking at four and a half millennia of human effort. And in 2017, researchers revealed there’s more than ...

Imagine being able to see through walls of steel and concrete without cutting, drilling, or opening a single door. For decades, this has been the dream of scientists and security experts tasked with ...

Ben may have been right way back when Stan Lee and Jack Kirby created him and the rest of the Fantastic Four 64 years ago, but we know a heck of a lot more about cosmic rays today. Back then, Grimm, ...

In a muon tomography detector, cosmic-ray muons interact with an object and strike scintillators that emit photons. Wavelength-shifting fibers transmit the photons to photodetectors that digitize the ...

Muons tend to scatter more from high-atomic-number materials, so the technique is particularly sensitive to the presence of materials such as uranium. As a result, it has been used to create systems ...

Muons continually bombard the ground at a known rate and angular distribution. As muons lose energy when passing through matter, their flux is attenuated depending on the integrated density along ...
