Dive into rotational dynamics with **“Physics Tutorial: Moment Of Inertia Of A Ring About An Axis.”** This video breaks down the concept of moment of inertia for a ring, explaining how mass ...

Master the mechanics behind motion in **“Solve The Speed Of A Mass Connected To A Rod Like A Pro.”** In this video, we break down a classic physics problem step by step, making complex concepts easier ...

An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

In science, there are thousands of ways to measure the world around us that the average person may never encounter. For example: Pascals to measure pressure, Candles to measure light intensity, and ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

There’s a lot more to the story of the Higgs boson than just one man named Higgs. Despite the appeal of the “lone genius” narrative, it’s rare that a discovery can be attributed solely to the work of ...

While it’s pretty high-concept physics, the team says the discovery could eventually open up a range of applications for ZrSiS similar to that of graphene. “It is a layered material, which means once ...

Some clusters of galaxies may not need dark matter in order for their physics to work. In new research, a physicist describes a “shell singularity,” where gravity applies without mass. Today’s ...

Physicists have taken one small-but-consequential step toward measuring the mass of an elusive "ghost particle" called a neutrino — an achievement that could poke a significant hole in the Standard ...
