They captured a single atom with an ordinary camera

The universe is vast and full of objects that are either too large or too small to be seen with the naked eye.

In order for human vision to be able to perceive these objects, humans have built huge telescopes and electronic microscopes to convert objects to a normal size for us.
It is this fact that David Nadlinger's photo from Oxford University is so impressive. He manages to capture a single atom with a very ordinary camera.
In the center of the picture is a pale blue dot - positively charged strontium atom -

Strontium ion (Strontium is the 38th chemical element of the Mendelean table with the designation Sr, belongs to alkaline earth metals). When ions of this type are illuminated with the correct blue-violet laser, they absorb the light particles and emit them back.

Overlander realized that if he set his camera to a sufficiently long exposure, he would have captured this broadcast in a digital image. To this end, he goes to the Oxford University lab and places the camera tripod so that she can capture the ion in a vacuum.
To get an idea of ​​how small the object of this image is, keep in mind that the distance between the two needles is 2 mm - roughly the same as the diameter of standard spaghetti. The pale blue dot at the center of the image is actually the ion, but if we have to be honest, it's not the real size, but just the light it returns from the laser.

" The idea of ​​seeing a single atom with an unarmed eye seemed to me

as a bridge between the microscopic world and our macroscopic reality, "says the student. " After a few calculations I realized the numbers were on my side. Then, on a quiet Sunday, I went to the laboratory with a camera and a tripod, and I was rewarded with the picture of a small light blue dot, "he told the media.

On February 12, 2018, Nadelder's photo won the prize of the 5th Annual World Scientific Edition of the British Council for Physical Sciences Research Council (EPSRC).
EPSRC is the main sponsor of UK physics and engineering research. More than 100 scientific photographs were taken in the competition, among which the photograph of an atom captured by an ordinary camera is not the only breathtaking and confusing mind.

" Every year we are impressed by the quality and creativity of our contestants and this year was no exception. They want to show the world the beauty of science and engineering, "said Prof. Tom Rodden, Executive Director of the agency.
