Think knots are only for sailors and fishermen? Think again.
Chemists have found a way to knot tiny strands of molecules together in test tubes through a series of chemical reactions. No, I’m not making this up.
Now up until now, only three knots have been created in total out of the 6 billion known prime knot formations…the trefoil, figure-eight and pentafoil knots. But a new study has discovered a fourth, known as the 819 knot.
While previous knots have been woven with two strands, researchers braided together three strands using a five-step chemical reaction to create the 819 knot.
Science AAAS has an interesting YouTube video that shows what these knots might look like if we were tiny enough to actually see them…
So what’s so special about this new knot?
