Leap Second: How Chinese Dam Affects Planet Rotation Speed
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.
‘Mathematics Is Practically Everywhere: in Physics, Programming, Economics, Sociology, Biology, and Medicine’

Her story shows what social networks can say about its users to someone who knows how to listen.
