Imaginary time is a wonky concept for our time-bound brains, but in quantum theory and mathematics, it’s a useful tool for exploring radiation's interaction with materials. A new study from scientists ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'. When you shine light through almost any transparent material, the gridlock of ...

For almost a century, physicists have been intrigued by the fundamental question: why are complex numbers so important in quantum mechanics, that is, numbers containing a component with the imaginary ...

A new method for measuring three different properties of light, at the same time, has been developed using an ...

Unless you're a physicist, you've probably only encountered quantum mechanics on TV. And even when it was explained, you might've still been a little confused. The field of quantum mechanics was ...

Imaginary numbers might seem like unicorns and goblins — interesting but irrelevant to reality. But for describing matter at its roots, imaginary numbers turn out to be essential. They seem to be ...

Human cognition and AI cognition may never share a full axis. But independence does not imply isolation either. The future ...

Mathematicians were disturbed, centuries ago, to find that calculating the properties of certain curves demanded the seemingly impossible: numbers that, when multiplied by themselves, turn negative.
