Simplify complex physics and math concepts with this easy guide to Lagrange multipliers! In this video, we explain how to calculate constraint forces in polar coordinates using step-by-step examples ...

Learn how to analyze the forces between three electric charges using fundamental electrostatics principles. This video explains force interactions, directions, and net force in a clear, step-by-step ...

When starting this ice challenge, most people just step on the side of the bowl and slide down to the bottom. Then you’re ...

Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then ...

Quantum mechanics has a way of sounding like pure philosophy until an experiment forces it into everyday language. In 2025, ...

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development. Sip a glass of wine, and you ...

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances will look different to my students who have studied physics through sports.

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

The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development. In March, a group of ...
