When light interacts with matter, its constituent electrons, ions and molecules move by following the electric field vector of light. These light-driven motions provide unique opportunities for the ...

I’ve already made the argument that numerical models (using computer code) should be an integral part of the introductory physics course. But what if you don’t know where to start? Suppose you are ...

Equal and Opposite Charges: The charges must be equal in magnitude but opposite in sign (+q and -q). This ensures that the ...

Low-intensity electric fields can disrupt the division of cancer cells and slow the growth of brain tumors, suggest laboratory experiments and a small human trial, raising hopes that electric fields ...
