10-year-old solves science riddle and co-authors paper
First he assisted his father with Sudoku, then helped him crack a chemistry problem that had puzzled him for years. Meet Linus Hovmöller Zou and his dad Sven
You cracked a puzzle about the structure of strange crystals called approximants that had gone unsolved for eight years. Tell us more.
Sven: Approximants are related to quasicrystals, which are ordered atomic structures but with symmetries that were believed to be impossible – for example, 5-fold symmetry. The approximants we studied have 5-fold and 10-fold symmetry.
The result was Linus's name on the paper he wrote with his father, published in the Philosophical Transactions of the Royal Society A this month.
What did you make of that?
Linus: It's rare and strange and cool. I don't know how many other 10-year-old kids have done this.
How did this father-son collaboration begin?
Linus: Me and my father did some Sudoku. He was like, "Let's put this number here and this number here," but I said that he was wrong. Then he was like, "You're better at puzzles than me," and he asked if I wanted to help with this thing that he'd been working on for a few years. We sat down and found the solutions to some of these crystals.
Sven: We cracked it together. We cracked four structures out of six remaining. It was pretty much a 50/50 effort.
Is there a similarity between solving Sudoku puzzles and piecing together diffraction patterns and electron micrographs to solve approximant structures?
Sven: Quite a lot actually. Linus's main contribution was coming at it with an absolutely clear mind, being smart and able to put the puzzle together. I sort of knew too many things and when I tried to do it myself, your brain just gets exhausted by all the different things you keep in your head at the same time. With a fresh, empty brain so to speak, you can do something. When solving problems, it is always good to have someone to discuss it with.
Linus: What we did was to solve a set of puzzles, where the pieces were "wheels" that could be connected in different ways.
Did it take long?
Linus: It took two days to find the solutions.
Linus is obviously exposed to a lot of science. Does a career in research beckon?
Sven: Because of our interest in the quasicrystals, we had Daniel Shechtman [winner of the chemistry Nobel for discovering quasicrystals] here for dinner after he got his prize. He talked a little bit with Linus and said he could become an excellent scientist. But we are not pushing him, he can be what he wants.
Linus: I don't know what I want to do yet.
When you're not solving crystal structures, what do you like to do?
Linus: I like to play computer games with my friends. I have met a lot of people in different countries when I play games; for example, Cyprus and Denmark. I also like to watch videos on YouTube.
