2018 Nobel Prize for physics goes to tools made from light beams – a particle physicist explains

By Todd Adams, Florida State University

The Nobel Prize for physics was awarded to three scientists for the inventions of optical tweezers – in which two laser beams can hold a tiny object – and a method for creating powerful lasers.

Our world is full of light, and we depend upon it to power life on our planet. So it is appropriate to honor three scientists who invented new ways of using light rays to explore our world.

The 2018 Nobel Prize in physics was awarded to Arthur Ashkin, Gérard Mourou and Donna Strickland for developing tools made from light beams. Ashkin won half of the prize for his work on optical tweezers, which are beams of light that can actually manipulate tiny objects like cells or atoms, while Mourou and...
