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 ...

This video analyzes a uniformly charged sphere using Gauss’s law. We walk through the symmetry arguments, choose the correct Gaussian surfaces, and derive the electric field both inside and outside ...

Korean researchers detect hidden semiconductor defects 1,000× more sensitively, boosting efficiency, lifespan, and design ...

At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts ...
