Фибрации Хопфа - Универсальный элемент мироздания, совершенно отчётливо обнаруживаемый на всех масштабах вселенной – от космологического устройства пространства в целом до структуры элементарных частиц.
Hopf fibration - A universal element of the universe, perfectly clearly detected on all scales of the universe - from the cosmological device of space as a whole to the structure of elementary particles.
We still do not know of reliable experimental observation of hopfions anywhere. But the hopfion is a pearl of mathematical physics and is sure to be found in several real mediums.
