In nature, most of our basic forces both attract and repel. In fact, gravity is the only exception. But, according to theorists, sound waves actually have negative gravity. Hosted by: Olivia Gordon ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Solve an electrostatics tape problem by calculating the charge on tapes using basic electric force concepts and clear step-by-step reasoning. Perfect practice for Coulomb’s law, charge interactions, ...

But only in the last 70 years have we known for certain they were there. In 1956, physicists Clyde Cowan and Frederick Reines ...

In a paper published January 21 in Nature, a team led by scientists at the University of Wisconsin–Madison have run complex numerical simulations of plasma flows that, while leading to turbulence, ...
