Tis the season to be jolly, and what better way to celebrate than plonking a great big Christmas tree in your living room?
One Applied Physics student from the Delft University of Technology (TU Delft) in the Netherlands had a different view of how her Christmas tree would look like this year, though.
"Behold, the world's smallest #ChristmasTree!" read a TU Delft post on Twitter.
Indeed, Maura Willems decided to create what could well be the world's tiniest Christmas tree.
Willems had a 51 atom-"big" Christmas tree, which roughly translates as the size of a DNA strand. To provide an idea, a human hair is about 40,000 times wider. We're talking small.
Willems' tree was precisely four nanometers tall, or four-millionths of a millimeter — without counting the tree-topper.
It's fun to see such complex devices build a cheery creation such as a Christmas tree. It may not be extremely useful, but it's a little light-hearted physics fun
