Researchers predict that this summer, the planet may once again approach its maximum rotation speed. The causes of this acceleration are not fully understood, and there is still no definitive scientific explanation. Leonid Zotov, Professor at the School of Applied Mathematics, MIEM HSE, notes that if, in the past, the so-called ‘leap second’ was added on New Year’s Eve, then for the first time in history, the question has arisen about whether it is time to subtract one.

Roman Gaydukov, Associate Professor at the MIEM HSE School of Applied Mathematics, has modelled the fluid flow around a rotating disk with small surface irregularities. His solution allows for predicting fluid flow behaviour without the need for powerful supercomputers. The results have been published in Russian Journal of Mathematical Physics.
