A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Is the electron a wave or a particle? Are the orbits of electrons in atoms similar to planetary orbits? What is the nature of light? Such were the questions that physicists were struggling with in the ...

On the morning of June 28, 1914, a Bosnian Serb student named Gavrilo Princip stood outside Moritz Schiller’s delicatessen near the Latin Bridge in Sarajevo. Sometime after 10:45 A.M., a motorcade ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

Thanks to advances in science, we’re now able to move beyond Bohm and Bohr’s theorizing; we can test their hypotheses through ...

The IBM Institute for Business Value (IBV) has published a beautiful book, good to read and also a substantial addition to any executive office: the fourth edition of The Quantum Decade. The 168-page ...

Picture Victorian London, but its skies are filled with airships. Steam-powered robots crowd the streets, mingling with people in top hats and petticoats. That type of retrofuturistic mash-up is the ...
