Вот почему Ракетные Двигатели за 100 лет почти НЕ изменились

Right now, try lifting yourself up by your own shoelaces — it won't work. Now answer this: how, then, does a rocket accelerate in absolute emptiness, where there's nothing to push off from? The answer is far more elegant than «the exhaust pushes against the air», as almost everyone assumes — and it uncovers a whole chain of things that school kept quiet about. In this video we descend inside a running engine, where a 3300-degree inferno rages — hotter than the melting point of any metal on Earth — and work out why it nonetheless doesn't turn into a candle. We'll understand Newton's third law the way you've never understood it; we'll look inside the nozzle, whose shape is calibrated to the micron; and we'll meet a deaf schoolteacher from Kaluga whose equation still has humanity by the throat and won't let it reach the stars. We'll break down why rockets are 90% fuel and deliberately fall to pieces on the way up, how the solid-fuel monster differs from the liquid-fuel one, how an engine weaker than a sheet of paper outruns them all, and what third, nuclear path might finally carry us to Mars. No formulas — just hands-on physics, jaw-dropping numbers, and the very truth you'll get wrong if you quit halfway. Watch to the end.
