Annual celebration of Lobachevsky's birthday by participants of 's student Mathematical Olympiad • Lobachevsky is the subject of songwriter/mathematician 's humorous song ' from his album. In the song, Lehrer portrays a Russian mathematician who sings about how Lobachevsky influenced him: 'And who made me a big success / and brought me wealth and fame? / Nikolai Ivanovich Lobachevsky is his name.'

Lobachevsky's secret to mathematical success is given as '!' , as long as one is always careful to 'call it, please, '.

According to Lehrer, the song is 'not intended as a slur on [Lobachevsky's] character' and the name was chosen 'solely for reasons'. • In 's 1969 novella 'Operation Changeling' – which was later expanded into the novel (1971) – a group of sorcerers navigate a with the assistance of the ghosts of Lobachevsky. The story also contains the line, 'Nikolai Ivanovich Lobachevsky is his name,' possibly a nod to the Tom Lehrer song.

Diagonal size of the screen, or as it was called before - picture tube, is 25 cm. TV set can be connected to the AC with voltage 176-243 V (you can forget about expensive stabilizers!) or to DC with voltage 11-14.5 V, for example, right in your car. It can receive color and black-and-white programs by any channel in the meter long wave band, this model ('D' index) can also receive programs in the decimeter wave band.

Engraving of Leskov 1862 saw the launch of Leskov's literary career, with the publication of 'The Extinguished Flame' (later re-issued as 'The Drought') in the March issue of magazine, edited by, followed by the short novels (May 1863) and (September, 1863). In August the compilation Three stories by M. Stebnitsky came out.

Another trip, to in summer, resulted in a report on the community there, which was published as a brochure at the end of the year. In February 1864 magazine began serially publishing his debut novel (the April and May issues of the magazine, stopped by the censors, came out in June). The novel bore 'every sign of haste and literary incompetence,' as its author later admitted, but proved to be a powerful debut in its own way. No Way Out, which satirized nihilist communes on the one hand and praised the virtues of the common people and the powers of Christian values on the other, scandalized critics of the radical left who discovered that for most of the characters real life prototypes could be found, and its central figure, Beloyartsev, was obviously a caricature of author and social activist. All this seemed to confirm the view, now firmly rooted in the Russian literary community, that Leskov was a right-wing, 'reactionary' author. In April wrote in his review 'A Walk In the Garden of Russian Literature' (, 1865, No.3): 'Can any other magazine be found anywhere in Russia, besides, that would venture to publish anything written by and signed as, Stebnitsky?
