In a groundbreaking discovery, physicists have observed light traveling in reverse, an event that significantly challenges ...

I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser’s group had a project dedicated to studying chemical reactions with attosecond pulses. Before ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many ...

Physics is the study of the underlying laws and mechanisms explaining how the universe works. Most of what we do in daily life is based on a principle or law of physics—dealing with forces, motion, ...

With the nature of the universe's two most elusive components up for debate, physicists have proposed a radical idea: Invisible particles called tachyons, which break causality and move faster than ...

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 ...

The Nobel Prize in physics was awarded to three scientists whose research demonstrates a way to create extremely short pulses of light that can provide information about processes inside atoms and ...

In a recent development that has stirred the scientific community, physicists have reported a fascinating observation of light traveling in reverse through a unique material. This extraordinary event ...
