In the world of optics, tiny structures called microcavities—often no wider than a human hair—play a crucial role in ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

hysics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming tools ...

Under the right conditions, superconducting magnets allow electricity to flow essentially undisturbed, producing intense magnetic fields for a variety of uses, including nuclear fusion experiments.

The magnetic field swirling around an enormous black hole, located about 55 million light-years from Earth, has unexpectedly switched directions. This dramatic reversal challenges theories of black ...

Tyler Loop took a moment to gather all the details in his head. It was Week 4. His Arizona team was playing at Utah, a temperate September Saturday in Salt Lake City last fall; around 87 degrees at ...

When a severe fault occurs within a transformer, the fault current escalates rapidly, making it challenging for differential protection systems to promptly isolate the faulty transformer. This delay ...

In the late 1980s, scientists realized they could understand the interior properties of the sun by observing the sound waves that resonate inside it. This technique, called helioseismology, revealed a ...

Leaker Majin Bu reports that Apple is developing a new iPhone 17 accessory: a shoulder strap for cases where the iPhone 17 hangs over your hip like a small bag. It keeps the iPhone always at hand, and ...
