A story about a small-big offer, which you can't refuse

Chen looked at the tiny chip through the microscope, but saw nothing. She kept zooming in on the picture more and more.

Chen looked at the tiny chip through the microscope, but saw nothing. She kept zooming in on the picture more and more. Next to her was her boyfriend, Elad, who stayed in this lab during the summer as part of a student exchange project between the Technion and the FZD institute in Dresden, Germany. She was very happy about the invitation to visit him and see what he was doing there.
Now she saw nothing, so she continued to zoom in on the image.
And suddenly she saw - a picture of a boy and a girl. Elad and Khan.
She continued to enlarge the image, but only when she reached a magnification of 250 times she was able to read: "Chen, will you marry me?" - and in German:
Chen, möchtest Du mich marryen? Elad.
When she recovered from the shock, Chen replied in the affirmative.
Chen received from Elad the smallest marriage proposal in the world. "Nanotechnology has interested me for a long time, so I was very happy about the opportunity to work in this field in Germany," he says. "Dresden is a very serious center in this field, and during my stay there I dealt with nanomechanical systems, and more specifically with nano-resonators. Today it is a very developed field, and its applications concern electronics, smell detection and other fields."
Elad worked at the institute under the close supervision of Joachen Grabing, a German postdoctoral student, and some time after his arrival there he asked for permission to carry out his original marriage proposal.
"The proposal was prepared using the stamping technology developed there, and I only had to do a few experiments to know how to achieve the best results in terms of resolution and aesthetics. I made several attempts and in the end I made the proposal that I showed to the microscope. It's basically imprinting (lithography), using electron beams, on a silicon chip coated with gold and titanium."
Elad grew up in Kiryat Bialik, where, in high school, he met Chen. Today they have been friends for 7.5 years, and in June, towards the end of Chen's studies at Bar Ilan (optometry), they will get married here in Israel. Elad is currently finishing his bachelor's degree and has already registered for a master's degree, at the Technion of course.
