Struggling with physics homework? In this video, we walk through step-by-step methods to calculate the electric field and electric potential for various charge distributions. Using clear examples and ...

Inductors may look like simple coils, but they play a key role in controlling current and storing energy in circuits. This ...

The irregular, swirling motion of fluids we call turbulence can be found everywhere, from stirring in a teacup to currents in the planetary atmosphere. This phenomenon is governed by the Navier-Stokes ...

Mathematician Richard Evan Schwartz of Brown University tackled the problem in a recent study by working backward from an existing polyhedral torus to answer questions about what would be needed to ...

Two ways of measuring how fast the universe is expanding disagree, a puzzle known as the Hubble tension. Tiny magnetic fields from the Big Bang may offer a solution.
