For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...

The dimensions of a physical quantity are the powers or exponents to which the base quantities are raised to represent that quantity. Note: Using the square brackets [ ] round a quantity means that we ...

A violation of one of the oldest empirical laws of physics has been observed by scientists. The experiments on purple bronze, a metal with unique one-dimensional electronic properties, indicate that ...

A physicist proposes that time has three dimensions instead of one, which could finally unite quantum mechanics and Einstein’s relativity into a single theory. The theory makes specific, testable ...

What if the Universe – and fundamentally, space itself – were like a pile of laundry? Have one. See this laundry pile? Looks just like our universe. No? Here, have another. See it now? It’s got three ...

Monolayers of transition metal dichalcogenides can exist in several structural polymorphs, including 2H, 1T and 1T′. The low-symmetry 1T′ phase has three orientation variants, resulting from the three ...
