Schrodinger's Cat is a hypothetical thought experiment created in 1935 by a man who loved physics and hated cats.

The more closely we observe the present moment, the more amorphous it becomes.

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.

The enigmatic saga of one of astrophysics' most wanted particles.

Quantum bits (aka qubits), the reader is assured, are somehow "entangled" such that they rely on one another. If more detail is needed, we're told entanglement links qubits no matter how far apart they are—so long as the qubits are “coherent.” This hardly helps! So let's try a different approach.

When a theory breaks, you learn how to build it better.

«ASK WEIRD QUESTIONS Einstein had a wild imagination. He asked himself questions like: What would he feel if he rode an elevator through outer space? What would he see if he chased a beam of light?»

You're six miles up, alone and falling without a parachute. Though the odds are long, a small number of people have found themselves in similar situations—and lived to tell the tale.

Many reactions emit energy, often in large amounts, but cosmic efficiency is another metric altogether. Here's how to maximize your output.

A century ago, quantum physics overthrew our view of a deterministic Universe. A profound 21st century theorem closes the door even further.

The icy ballet of stone upon ice makes curling one of the most intriguing sports of the Winter Olympics. But scientists still haven't quite figured out the physics of how they move.

Over the span of a single lifetime, the world has changed in ways that would have been virtually unimaginable in the first half of the 20th century. Two major breakthroughs that occurred in physics —…

Watching, modeling and even playing winter sports help students internalize physics concepts, including acceleration, momentum and friction.

You can apply the classic laws of physics to your to-do list to be more productive—starting with Newton's famous first law.
