WASHINGTON -- Some might find this look through the Prism as “illogical.” Scientists at New York University have developed for the first time a way to use oscilating beams of light to move an object.
The scientists used something called a Bessel beam which is a type of laser that directs light in concentric circles around a single dot rather than as a single beam. However, unlike most lasers, the light from a Bessel beam is not diffracted if it encounters an object in its path. It's this property that allows for pulling a particle.
This represents one more step into the land of science fiction. Entering the Prism to explain how physicists are co-opting one of Captain Kirk's favorite tools is NYU professor of physics, David Grier.
You never know what you’ll discover when you look through the Prism… colors, textures, answers. Every episode we will delve into the human mind, nature, or into the latest research to explore the facts and facets. Along the way, we’ll break ground, cause a few ripples, and hopefully, share a few laughs.The results are never final, but the quest for truth is unending… on the Prism.
