The microscope weighs two tonnes, operates at minus 268 degrees Celsius and magnifies the atomic surface more than 100 million times. Remotely operated on a standard computer, researchers used the microscope to control a super-sharp needle along a copper surface to "feel" atoms. Only one nanometre from the surface, which is a billionth of a metre in distance, the needle can attract atoms and molecules on the surface and pull them to a specified location. The moving atom makes a unique sound that is critical feedback in determining how many positions it has moved. As the movie was being created, the scientists rendered still images of the individually arranged atoms, resulting in 242 single frames. As computer circuits shrink toward atomic dimensions, researchers are running into physical limitations using traditional techniques. "As data creation and consumption continue to get bigger, data storage needs to get smaller, all the way down to the atomic level," Mr Heinrich said. "We’re applying the same techniques used to come up with new computing architectures and alternative ways to store data to making this movie."
