Understand the principles of rigid body equilibrium and torque. Learn how forces and rotations balance in physical systems.

Cats rarely crash and burn, always seeming to land on their feet. But how? Researchers have uncovered the secret behind their midair control.

The secret to this acrobatic skill lies in an extremely flexible part of the spine that allows cats to twist in the air and land safely.

Explore 25 science experiments that defied the laws of physics, revealing mind-bending phenomena that challenge intuition.

Scientists at Harvard have built a miniature device that can twist and tune light in real time. By rotating two stacked photonic crystals and adjusting their spacing with a tiny mechanical system, ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

Animals come in an extraordinary range of body shapes. A starfish looks nothing like an earthworm, a mouse, or a human. Yet even closely related species can appear radically different: corals, ...

Today's sea level rise is significant enough to slow the rotation of the planet by just over a millisecond per century.

These long E. coli cells can swim their way into tubes, like catheters, so DeCurtis et al. studied the dynamics of elongated ...

Researchers at the University of Konstanz have uncovered a new mechanism of sliding friction: resistance to motion that ...

The familiar phenomenon has puzzled researchers for centuries, but experiments are finally making sense of its unruly behaviours.

Twenty years on, relive the iconic scene from Sir David Attenborough's Planet Earth that changed our understanding of how polar bears adapt to survive. Once pelted with pebbles, India's ...
