A university student named David Nadlinger has won the top prize in a science photography contest held by UK’s Engineering and Physical Sciences Research Council after capturing a photo of a single atom.
The photo, titled “Single Atom in an Ion Trap” shows a single atom suspended in midair. It was captured using a standard DSLR camera and shows the tiniest speck of a positively charged strontium atom. The atom’s place is being held by an electric field created by two metal electrodes.
