The S-300PMU [SA-10 land-based, SA-N-6 naval version] surface-to-air missile system is able to engage a number of targets simultaneously, countering intensive aircraft raids at low-to-high altitude. The SA-10 offers significant advantages over older strategic surface-to-air missile systems, including multitarget handling and engagement characteristics, a capability against low altitude targets with small radar
cross-sections such as cruise missiles, a capability against tactical ballistic missiles, and possibly a potential to intercept some types of strategic ballistic missiles. It was Russia's best system in this class. Real threat to enemy planes and ballistic missiles. Costs hundres thousands dollars each. And now a budget version - inflatable. First check the real thing:
We already have mentioned the strange behavior of Gregory Perelman. Today the Fields medal congress has started in Madrid, and their press service officially declared that Perelman refuses to accept his Field’s medal, an award that’s being considered as important among mathematicians as Nobel prize among other scientists. It is not known why Nobel chose not to establish a prize in Mathematics, although there are several
theories about the lack of one, nevertheless the history of the Fields Medal begins in the Committee of the International Congress set up by the University of Toronto in November of 1923, with the purpose of organizing the 1924 Congress to be held in Toronto. This decision of the bright mathematician confuses the Field’s medal commission. They actually now don’t know to whom they can award the prize.
