Yeah. Nobody at all nowadays reads Kovalevskaya’s own mathematical writings as part of their “schooldays” education on calculus or applied mathematics. Not even Russians (or more aptly, not even French or Germans, since Kovalevskaya’s major publications on mathematics were in those international languages of scholarship rather than in the “provincial” minority language Russian). They read modern textbooks instead.
However, the OP may instead have been referencing Kovalevskaya’s non-mathematical writings, particularly her memoiric A Russian Childhood and Nihilist Girl. Sounds plausible to me that Russian schoolchildren would be expected to read (parts of) those, just as many American high-schoolers are expected to read Melville’s somewhat autobiographical Moby-Dick.

They’ve been linked in another thread . . . and they’re terrible.
I suspect our friend is actually a Tellarite. He does not argue for a reason; he simply argues.
Can we get back on-topic to discussing intimate frictions please?
I am abashed that you Westerners are unfamiliar with the superior Soviet marital aids, such as Khrushchev-Yeltsin Jelly (far superior to the American K-Y Jelly), and Glorious Proletariat condoms! Certainly every schoolboy would be familiar with them.
Ribbed, for the pleasure of the masses!
