The film demonstrates an experiment using an apparatus to observe the behavior of electrons in a uniform magnetic field. It explains how electrons are accelerated by an electron gun and then deflected ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the ...

Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment has revealed the radius of the proton's mass that is generated by the ...

The film explains the concept of electrons and their role in electric circuits. It describes how electric current is the flow of electric charges, primarily electrons, which cannot be seen but can be ...

Bit by bit, physicists are winnowing down the potential masses for hypothetical particles called axions. If they exist, the subatomic particles could make up dark matter, a mysterious source of mass ...

Scientists have made the most precise measurement yet of the electron's atomic mass. "It is a major technical improvement," said Edmund Myers, a physicist at Florida State University, who wrote an ...

Isaac Asimov dubbed neutrinos “ghost particles.” John Updike immortalized them in verse. They’ve been the subject of several Nobel Prize citations, because these weird tiny particles just keep ...

NEWPORT NEWS, VA – Nuclear physicists may have finally pinpointed where in the proton a large fraction of its mass resides. A recent experiment carried out at the U.S. Department of Energy’s Thomas ...
