<< a certain geometrical structure of knots, which scientists call a Hopfion, manifests itself in unexpected corners of the universe, ranging from particle physics, to biology, to cosmology. >>
<< In a recent theoretical study, (..) (AA) discovered the presence of the Hopfion structure in nano-sized particles of ferroelectrics. >>
<< The Hopfion is a very abstract mathematical concept, (..) but the structure shows up in hydrodynamics, electrodynamics and even in the packing of DNA and RNA molecules in biological systems and viruses. >> Valerii Vinokur
<< When we visualized the polarization, we saw the Hopfion structure emerge, (..) We thought, wow, there is a whole world inside of these nanoparticles. >> Igor Luk'yanchuck.
