The notion of dimension at first seems intuitive. Glancing out the window we might see a crow sitting atop a cramped flagpole experiencing zero dimensions, a robin on a telephone wire constrained to ...

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible field, but from the hidden geometry of space itself. Instead of treating extra ...

In the illustration: A tesseract (a four-dimensional cube) and the "shadow" it casts on a plane—the quasicrystal discovered by Shechtman. According to Prof. Bartal, "The fact that a quasicrystal is a ...

Physicists have long treated mass as a basic ingredient of nature, something particles simply possess, even as the Higgs mechanism explained only part of the story. A new wave of theoretical work now ...

Linked Weyl surfaces, a novel type of topological phase that exists in five-dimensional space, have now been experimentally observed. The work provides a unique platform for exploring various ...
