The goal of drive-system engineers is usually pretty straightforward. Specify the smallest motor and drive needed to accelerate and run a load at a required rate, and determine the braking forces ...

The following is an excerpt from Seven Brief Lessons On Physics, by Carlo Rovelli. These lessons were written for those who know little or nothing about modern science. Together they provide a rapid ...

From Newton's Laws of Motion to electric forces, these concepts explain why matter behaves the way it does.artpartner-images/The Image Bank/Getty Images Physics is the science that quantifies reality.

A new study enhances hydrogen molecule predictions, achieving unprecedented precision in testing fundamental physics and ...

One of the most well-accepted physical theories makes no logical sense. Quantum mechanics, the theory that governs the smallest possible spaces, forces our human brains to accept some really wacky, ...

Using basic principles of physics, scientists can compute how much of each type of lithium should have been created during the Big Bang. But, the theory doesn’t match the data. The difference between ...
