In this video, we derive the electric field of a long uniformly charged rod using Gauss’s law. We choose an appropriate Gaussian surface, apply symmetry arguments, and walk through the math ...

In this video, we use Gauss’s law to find the electric field of a uniformly charged sphere. We derive the field both inside and outside the sphere, explain the symmetry behind the Gaussian surface ...

An application that can tap into a smartphone’s built-in barometer can be a helpful tool for teaching students about Stevin’s ...

A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

This is where Emmy Noether, a groundbreaking German mathematician, comes into the picture. She found a breathtakingly simple ...

Here’s what you’ll learn when you read this story: Researchers have made a breakthrough in applying the first law of thermodynamics to complex systems. The law is a bedrock of physics, but has long ...

Solar cells face significant challenges when deployed in outer space, where extremes in the environment decrease the efficiency and longevity they enjoy back on Earth. University of Toledo physicists ...

The second law of thermodynamics demands that the entropy of any closed macroscopic system should never decrease. The laws of physics naturally drive systems towards states of increasing disorder and ...

Welcome to the Department of Physics and Astronomy at the University of Delaware, where the pursuit of scientific discovery and innovation meets cutting-edge research and academic excellence. Our ...

The Martin A. Fisher School of Physics enjoys an international reputation for excellence in research, and is one of the highest-ranked of its size in the country. The department offers rigorous ...

Where next? Quantum metrology, fusion and medical physics are three hot topics to be featured on Physics World Live this year. (Courtesy: iStock/shutter_m) I used to set myself the challenge every ...
