“A Physics student at Delft University of Technology creates world’s smallest Christmas tree made up of just 51 atoms from a perfect crystal lattice. The tree is exactly 4 nanometers tall, or 4 millionths of a millimeter.
The student Maura Willems for her graduation, uses high-powered microscope to build small structures, literally atom by atom, in order to study their quantum mechanical properties. Then changed each one’s position.”
