When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

World Quantum Day is celebrated every 14 April, with the numbers taken from Planck's constant, 4.14 × 10⁻¹⁵ electron-volts per second. This constant is central to understanding how energy behaves at ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means. Everyone has their favourite example of a ...

During the 20th century, researchers pushed the frontiers of science further than ever before with great strides made in two very distinct fields. While physicists discovered the strange ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...

Nobel Committee member Göran Johansson explains elements of quantum mechanics during a press conference to announce the winners of the 2025 Nobel Prize in Physics on October 7 in Stockholm. Christine ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...
