Animation Science

Take a Deep Dive Into the Relative Scale of Atoms Through the Tip of a Ballpoint Pen

August 30, 2019

Laura Staugaitis

The Super Zoom is a new computer-generated animation that shows how everything in the universe is made of minuscule foundational elements. The 3 minute-long short grounds itself with a relatable starting point: a ballpoint pen and ruled paper. On the lower right side of the screen, a scale adjusts as the “camera” zooms further and further in, breaking through the pen tip’s metal surface into more and more minute layers. The Super Zoom was created by Pedro Machado, a computer graphics designer who is based in Brazil. You can watch more of Machado’s videos on Vimeo.

Photo of a Single Atom Wins Top Prize in Science Photography Contest

You might need your glasses for this one. Quantum physicist David Nadlinger from the University of Oxford managed to capture an image that would have been impossible only a few years ago: a single atom suspended in an electric field viewable by the naked eye. The amazing shot titled “Single Atom in an Ion Trap” recently won the overall prize in the UK’s Engineering and Physical Sciences Research Council (EPSRC) science photo and imaging contest. You can see the atom in the shot above, the tiny speck at the very center.

To be clear, the photo doesn’t capture just the atom, but rather light emitted from it while in an excited state. From the EPSRC:

‘Single Atom in an Ion Trap’, by David Nadlinger, from the University of Oxford, shows the atom held by the fields emanating from the metal electrodes surrounding it. The distance between the small needle tips is about two millimetres.

When illuminated by a laser of the right blue-violet colour the atom absorbs and re-emits light particles sufficiently quickly for an ordinary camera to capture it in a long exposure photograph. The winning picture was taken through a window of the ultra-high vacuum chamber that houses the ion trap.

Laser-cooled atomic ions provide a pristine platform for exploring and harnessing the unique properties of quantum physics. They can serve as extremely accurate clocks and sensors or, as explored by the UK Networked Quantum Information Technologies Hub, as building blocks for future quantum computers, which could tackle problems that stymie even today’s largest supercomputers.

“The idea of being able to see a single atom with the naked eye had struck me as a wonderfully direct and visceral bridge between the minuscule quantum world and our macroscopic reality,” shared Nadlinger. “A back-of-the-envelope calculation showed the numbers to be on my side, and when I set off to the lab with camera and tripods one quiet Sunday afternoon, I was rewarded with this particular picture of a small, pale blue dot.”

Designed by engineer André Waterkeyn for the 1958 World’s Fair in Brussels, Belgium, Atomium is a 102m (335 ft) tall model of a unit cell of an iron crystal (each sphere representing an atom) enlarged 165 billion times. Filmmaker Richard Bently was allowed access to shoot this great exterior and interior timelapse of the building which is comprised of 27 sequences filmed over five nights and two days. (via Vimeo)
