How Were the Pyramids Built? Engineers Suggest a New Theory ...

Light can tie knots—literally. Engineers at Duke University have managed to manipulate laser beams to form intricate 3D patterns called optical knots, using custom-designed optics. These twisted beams ...

Researchers also believe that the intricacies of the resulting knots could be used to trap and manipulate tiny particles in 3D space. “Before we can actually use optical knots for any kind of ...

“We can use knot theory to analyse the shapes of many things in nature, especially string-like objects,” she adds. “While our research is highly fundamental, it has the bigger picture in ...
