Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Scientists at the European Organization for Nuclear Research (CERN)—operators of the world's largest particle physics lab—have conducted a groundbreaking experiment demonstrating a new technique for ...

Researchers have demonstrated a new technique for accelerating electrons to very high energies over short distances. The Large Hadron Collider (LHC) at the European Organization for Nuclear Research ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

Galileo’s most famous experiment has taken a trip to outer space. The result? Einstein was right yet again. The experiment confirms a tenet of Einstein’s theory of gravity with greater precision than ...

The ultra smooth mirror was required to enable the researchers to perform experiments on electron acceleration in medium density gas jets, with the subsequent goal to ...

According to legend, Galileo dropped weights off the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...
