Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

This interaction could help explain both why quantum processes can occur within environments like the brain and why we lose ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Physicists have long relied on elegant theorems to connect the abstract math of quantum theory with the tangible behavior of ...

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 ...
