Members of the auk family, such as these guillemots and puffins... propel themselves, not with their feet like ducks, but with their wings, and they … - David Attenborough

How is it that [birds] can withstand the pull of gravity that keeps the rest of us tied so firmly to the ground? The secret is a wing with a thick, rounded front edge that curves gently downwards toward the back edge which is very thin. As thin, in fact, as a feather. As the bird glides forward, the air flowing under the wing is impeded by the wing's downward curve so it becomes slightly compressed, and that pushes the wing up. At the same time, the air flowing across the top of the wing is deflected upwards by the wing's front edge, so reducing its pressure. If the air is moving fast enough, then the slight suction from above, combined with the push from beneath will be enough to lift the bird into the air [...] and ample to keep it aloft.

This City in Ukraine was once Home to almost 50 thousand people. It had everything a community would need for a comfortable life. But on the 26th of April 1986, it suddenly became uninhabitable. The nearby Nuclear Power Station of Chernobyl exploded. And less than in 48 hours the city was evacuated. No one has lived here since

I don't think any human society is prepared to make decisions which they may not like if they're made by people who don't speak the same language... It's very easy, as we all know, to be very tolerant of minorities until they become majorities and you find yourself a minority. It's easy to say 'Oh yes, these lovely people – I love the way they wear such interesting costumes.' You know, that's fine until some day you find that they're actually telling you what to do and that they've actually taken over the town council and what you thought was your home was not. I'm not supporting it; I'm saying it's what it is.
