  <pre><code>'''And what struck me was every place that I went to to see these telescopes, the astronomers and cosmologists are in search of a certain kind of silence, whether it's silence from radio pollution or light pollution or whatever.
  And it was very obvious that, if we destroy these silent places on Earth, we will be stuck on a planet without the ability to look outwards, because we will not be able to understand the signals that come from outer space.
  Thank you.

At the INK Conference, science writer Anil Ananthaswamy tours us around these amazing installations, taking us to some of the most remote and silent places on Earth.&lt;/description&gt;

  We really need to put the best we have to offer within reach of our children.
  If we don't do that, we're going to get the generation we deserve.
  They're going to learn from whatever it is they have around them.'''
