In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley ...
For nearly two centuries, physics textbooks have treated light as magnetically indifferent to the materials it passes through ...
An experiment 180 years ago first demonstrated a connection between light and electromagnetism – but the link is deeper than ...
A single sewing needle is tiny enough to slip through fabric unnoticed, yet physics suggests that if it somehow struck Earth at light speed, the result would look less like a pinprick and more like a ...
Since then, countless experiments have confirmed that light always travels at the same speed in a vacuum — about 300,000 ...
The innovative Celeritas project, led by the Department of Energy’s Oak Ridge National Laboratory, provides a software tool that makes sure simulations used to analyze particles can run on the fastest ...
How do plants use sunlight to make their own food? We use light for more than just to see. We can use light’s energy to make electricity, clean water, even dry our clothes. Plants use sunlight to make ...
Most of us can relate to being worried about inflation: we are all concerned about the cost of living and what our political leaders are doing to address it. Sometimes, I have to remind myself that we ...
